The magnetic motor will be cheaper than a standard motor to make, as the rotor and stator assemblies can be set into plastic housings, due to the fact that the system creates very little heat. Further, with the motor's energy efficiency, it will be well suited for any application where a motor has limited energy to drive it. While development is still focused on replacing existing devices, Minato says that his motor has sufficient torque to power a vehicle. With the help of magnetic propulsion, it is feasible to attach a generator to the motor and produce more electric power than was put into the device. Minato says that average efficiency on his motors is about 330 percent.

 

Mention of Over Unity devices in many scientific circles will draw icy skepticism. But if you can accept the idea that Minato's device is able to create motion and torque through its unique, sustainable permanent magnet propulsion system, then it makes sense that he is able to get more out of the unit than he puts in in terms of elctrical power. Indeed, if the device can produce a surplus of power for longer periods, every household in the land will want one.

 

"I am not in this for the money," Minato says. "I have done well in my musical career, but I want to make a contribution to society -- helping the backstreet manufacturers here in Japan and elsewhere. I want to reverse the trends caused by major multinationals. There is a place for corporations. But as the oil industry has taught us, energy is one area where a breakthrough invention like this cannot be trusted to large companies."

 

Minato was once close to making a deal with Enron. But today, he is firmly on a mission to support the small and the independent -- and to go worldwide with them and his amazing machine. "Our plan is to rally smaller companies and pool their talent, and to one day produce the technology across a wide range of fields."

 

When we first got the call from an excited colleague that he'd just seen the most amazing invention -- a magnetic motor that consumed almost no electricity -- we were so skeptical that we declined an invitation to go see it. If the technology was so good, we thought, how come they didn't have any customers yet?

We forgot about the invitation and the company until several months later, when our friend called again. "OK," he said. "They've just sold 40,000 units to a major convenience store chain. Now will you see it?" In Japan, no one pays for 40,000 convenience store cooling fans without being reasonably sure that they are going to work.

 

The Maestro ~

 

The streets of east Shinjuku are littered with the tailings of the many small factories and workshops still located there -- hardly one's image of the headquarters of a world-class technology company. But this is where we are first greeted outside Kohei Minato's workshop by Nobue Minato, the wife of the inventor and co-director of the family firm. The workshop itself is like a Hollywood set of an inventor's garage. Electrical machines, wires, measuring instruments and batteries are strewn everywhere. Along the diagram-covered walls are drill presses, racks of spare coils, Perspex plating and other paraphernalia. And seated in the back, head bowed in thought, is the 58-year-old techno maestro himself. Minato is no newcomer to the limelight. In fact, he has been an entertainer for most of his life, making music and producing his daughter's singing career in the US. He posseses an oversized presence, with a booming voice and a long ponytail. In short, you can easily imagine him onstage or in a convertible cruising down the coast of California -- not hunched over a mass of wires and coils in Tokyo's cramped backstreets. Joining us are a middle-aged banker and his entourage from Osaka and accounting and finance consultant Yukio Funai. The banker is doing a quick review for an investment, while the rest of us just want to see if Minato's magnetic motors really work. A prototype car air conditioner cooler sitting on a bench looks like it would fit into a Toyota Corolla and quickly catches our attention. Seeing is Believing ~

Nobue then takes us through the functions and operations of each of the machines, starting off with a simple explanation of the laws of magnetism and repulsion. She demonstrates the "Minato Wheel" by kicking a magnet-lined rotor into action with a magnetic wand. Looking carefully at the rotor, we see that it has over 16 magnets embedded on a slant -- apparently to make Minato's machines work, the positioning and angle of the magnets is critical. After she kicks the wheel into life, it keeps spinning, proving at least that the design doesn't suffer from magnetic lockup. She then moves us to the next device, a weighty machine connected to a tiny battery. Apparently the load on the machine is a 35kg rotor, which could easily be used in a washing machine. After she flicks the switch, the huge rotor spins at over 1,500 rpms effortlessly and silently. Meters show the power in and power out. Suddenly, a power source of 16 watt or so is driving a device that should be drawing at least 200 to 300 watts. Nobue explains to us that this and all the other devices only use electrical power for the two electromagnetic stators at either side of each rotor, which are used to kick the rotor past its lockup point then on to the next arc of magnets. Apparently the angle and spacing of the magnets is such that once the rotor is moving, repulsion between the stators and the rotor poles keeps the rotor moving smoothly in a counterclockwise direction. Either way, it's impressive. Next we move to a unit with its motor connected to a generator. What we see is striking. The meters showed an input to the stator electromagnets of approximately 1.8 volts and 150mA input, and from the generator, 9.144 volts and 192mA output. 1.8 x 0.15 x 2 = 540mW input and 9.144 x 0.192 = 1.755W out. But according to the laws of physics, you can't get more out of a device than you put into it. We mention this to Kohei Minato while looking under the workbench to make sure there aren't any hidden wires. Minato assures us that he hasn't transcended the laws of physics. The force supplying the unexplained extra power out is generated by the magnetic strength of the permanent magnets embedded in the rotor. "I'm simply harnessing one of the four fundamental forces of nature," he says. Although we learned in school that magnets were always bipolar and so magnetically induced motion would always end in a locked state of equilibrium, Minato explains that he has fine-tuned the positioning of the magnets and the timing of pulses to the stators to the point where the repulsion between the rotor and the stator (the fixed outer magnetic ring) is transitory. This creates further motion -- rather than a lockup. (See the sidebar on page 41 for a full explanation). Real Products ~ Nobue Minato leads us to the two devices that might convince a potential investor that this is all for real. First, she shows us the cooling fan prototype that is being manufactured for a convenience store chain's 14,000 outlets (3 fans per outlet). The unit looks almost identical to a Mitsubishi-manufactured fan unit next to it, which is the unit currently in wide use. In a test, the airflow from both units is about the same. The other unit is the car air conditioning prototype that caught our eye as we came in. It's a prototype for Nippon Denso, Japan's largest manufacturer of car air conditioners. The unit is remarkably compact and has the same contours and size as a conventional unit. Minato's manufacturing skills are clearly improving.

The Banker and his Investment ~

Minato has good reason to complain about Japan's social and cultural uniformity. For years, people thought of him as an oddball for playing the piano for a living, and bankers and investors have avoided him because of his habit of claiming that he'd discovered a breakthrough technology all by himself -- without any formal training. However, the Osaka banker stands up after the lecture and announces that before he goes, he will commit \100 million to the investment pool. Minato turns to us and smiles. We brought him good luck, and this was his third investor in as many weeks to confirm an interest. Bringing the Tech to the Table ~ With the audience gone, we ask Minato what he plans to do to commercialize the technology. His game plan is simple and clear, he says. He wants to retain control, and he wants to commercialize the technology in Japan first -- where he feels he can ensure that things get done right. Why doesn't he go directly to the US or China? His experiences in both countries, he suggests, have been less than successful. "The first stage is critical in terms of creating good products and refining the technology. I don't want to be busy with legal challenges and IP theft while doing that." Still, the export and licensing of the technology are on his agenda, and Minato is talking to a variety of potential partners in other countries. Whereas another inventor might be tempted to outsource everything to a larger corporation, part of what drives Minato is his vision of social justice and responsibility. The 40,000 motors for the convenience store chain are being produced by a group of small manufacturers in Ohta-ku and Bunkyo-ku, in the inner north of Tokyo -- which is becoming a regional rust belt. Minato is seized with the vision of reinvigorating these small workshops that until the 80s were the bedrock of Japan's manufacturing and economic miracle. Their level of expertise will ensure that the quality of the motors will be as good as those from any major company. International Prep " Despite his plan to do things domestically first, Minato is well prepared for the international markets. He is armed with both six years of living and doing business in Los Angeles in the early 90s -- and with patent protection for over 48 countries. His is hardly a provincial perspective. His US experience came after playing the piano for a living for 15 years. He began tinkering with his invention in the mid-70s. The idea for his magnetic motor design came from a burst of inspiration while playing the piano. But Minato decided to drop everything in 1990 to help his daughter Hiroko, who at the age of 20 decided that she wanted to be a rhythm and blues star in the US. Minato is a strong believer in family: If Hiroko was going to find fame and fortune in the US, Dad had better be there to help manage her. He suceeded in helping Hiroko to achieve a UK dance chart number one hit in 1995. In 1996 Minato returned to Japan and his magnetic motor project. The following year he displayed his prototypes to national power companies, government officials and others at a five-day conference in Mexico City. Interest was palpable, and Minato realized that his invention might meet a global need for energy-saving devices.

Subsequent previews and speeches in Korea and Singapore further consolidated his commitment to bringing the invention to fruition, and he was able to bring in several early-stage investors.

During the late 90s, Minato continued to refine his prototypes. He also stayed in constant contact with his lawyer, registering patents in major countries around the world. Through his experiences in the US he realized that legal protection was critical, even if it meant delaying release of the technology by a couple of years. Ironically, by the time he'd won patents in 47 countries, the Japanese patent office turned him down on the grounds that "[the invention] couldn' t possibly work" and that somehow he was fabricating the claims. But a few months later they were forced to recant their decision after the US patent office recognized his invention and gave him the first of two patents. As Minato notes: "How typical of Japan's small-minded bureaucrats that they needed the leadership of the US to accept that my invention was genuine." By 2001, the Minatos had refined their motors and met enough potential investors to enter into a major international relationship, initially with a Saudi company, to be followed thereafter by companies in the US and elsewhere. However, fate dealt the investors and Minato's business a serious blow when the World Trade Center was attacked in New York. The Saudis retreated, and Minato's plans fell back to square one. Now Minato is once again ready to move. With the first order in the works and more orders pending successful prototypes, he has decided that investors don't have to be primary partners. He is actively accepting inquiries from corporate investors who can bring strategic advantages and corporate credibility with them. His company, Japan Magnetic Fan, will make a series of investment tie-up announcements in the first and second quarters of 2004. Implications ~ Minato's motors consume just 20 percent or less of the power of conventional motors with the same torque and horse power. They run cool to the touch and produce almost no acoustic or electrical noise. They are significantly safer and cheaper (in terms of power consumed), and they are sounder environmentally. The implications are enormous. In the US alone, almost 55 percent of the nation's electricity is consumed by electric motors. While most factory operators buy the cheapest motors possible, they are steadily being educated by bodies like NEMA (National Electrical Manufacturers Association) that the costs of running a motor over a typical 20-year lifespan comprise a purchase price of just 3 percent of the total, and electricity costs of 97 percent. It is not unusual for a $2,000 motor to consume $80,000 of electricity (at a price of .06 cents per kilowatt hour). Since 1992, when efficiency legislation was put into place at the US federal level, motor efficiency has been a high priority -- and motors saving 20 percent or so on electrical bills are considered highly efficient. Minato is about to introduce a motor which saves 80 percent, putting it into an entirely new class: The $80,000 running cost will drop to just $16,000. This is a significant savings when multiplied by the millions of motors used throughout the USA and Japan -- and eventually, throughout the world. The Devices ; Minato's invention and its ability to use remarkably less power and run without heat or noise make it perfect for home appliances, personal computers, cellphones (a miniature generator is in the works) and other consumer products.

Magnetic Rotation Apparatus

 

(June 14. 1998)

 

Kohei Minato

 

Abstract --- The magnetic rotation apparatus of the present invention has first and second rotors rotatably supported and juxtaposed. The first and second rotors are connected so as to be rotatable in opposite directions in a cooperating manner. A number of permanent magnets are arranged on a circumferential portion of the first rotor at regular intervals, and just as many permanent magnets are arranged on a circumferential portion of the second rotor at regular intervals. Each permanent magnet has one magnetic polarity located radially outward from the rotors, and has the other magnetic polarity located radially inward toward the rotors. The polarity of each permanent magnet, which is located radially outward from the rotors, is identical. When the first and second rotors are rotated in a cooperating manner, the phase of rotation of the permanent magnets of one rotor is slightly advanced from that of the permanent magnets of the other rotor. One of the permanent magnets of one rotor is replaced with the electromagnet. The radially outward polarity of the electromagnet can be changed by reversing the direction in which a current is supplied to the electromagnet.

  

TECHNICAL FIELD

 

The present invention relates to a magnetic rotation apparatus in which a pair of rotors are rotated by utilizing a magnetic force.

 

BACKGROUND ART

 

An electromotor is well known as a rotation apparatus utilizing a magnetic force. For example, an AC electromotor comprises a rotor having a coil, a stator surrounding the rotor, and a plurality of electromagnets, disposed on the stator, for generating a rotating magnetic field. An electric power must be constantly supplied to the electromagnets in order to generate the rotating magnetic field and keep the rotor rotating, i.e., an external energy, or electric energy, is indispensable for the rotation of the rotor. Under the circumstances, a magnetic rotation apparatus, which employs permanent magnets in lieu of electromagnets and can rotate a rotor only by a magnetic force of the permanent magnets, is highly desirable. The present application proposes a magnetic rotation apparatus which comprises a pair of rotors rotatable in opposite directions in a cooperating manner, and a plurality of permanent magnets stationarily arranged at regular intervals on the peripheral portion of each rotor. One end portion of each permanent magnet of both rotors, which has the same polarity, is located radially outward of the rotors. When the two rotors are rotated in a cooperating fashion, a permanent magnet on one rotor and a corresponding permanent magnet on the other, which form a pair, approach and move away from each other periodically. In this case, the phase of rotation of the magnet on one rotor advances a little from that of the corresponding magnet on the other rotor. When the paired permanent magnets approach each other, magnetic repulsion causes one rotor to rotate. The rotation of one rotor is transmitted to the other rotor to rotate the same. In this manner, other pairs of magnets on both rotors sequentially approach each other, and magnetic repulsion occurs incessantly. As a result, the rotors continue to rotate. In the above apparatus, in order to stop the rotation of the rotors, a brake device is required. If an ordinary brake device is mounted on the magnetic rotation apparatus, the entire structure of the apparatus becomes complex, and a driving source for the brake device must be provided separately. The present invention has been developed in consideration of the above circumstances, and its object is to provide a magnetic rotation apparatus including a brake device for suitably stopping the rotation of rotors.,DISCLOSURE OF THE INVENTION The magnetic rotation apparatus of the present invention is provided with magnetic force conversion means which is substituted for at least one pair of permanent magnets of the paired rotors. In a normal state, the magnetic force conversion means causes a magnetic repulsion, as in the other pairs of permanent magnets. When it is intended for the rotors to stop, the magnetic force conversion means causes a magnetic attraction force. Since a magnetic attraction force can be produced between the rotors at any time, the magnetic attraction force serves to stop the rotors. The brake device constituted by the magnetic force conversion means differs from an ordinary brake device which forcibly stops a pair or rotors by using a frictional force. In the brake device of this invention, by converting a magnetic repulsion force to a magnetic attraction force, the rotors can be braked in the state that the movement of the rotors is reduced. Thus, the rotors can be stopped effectively. BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic perspective view showing a magnetic rotation apparatus according to an embodiment of the invention;

FIG. 2 is a schematic plan view showing the relationship between the first and second rotors; FIG. 3 is a perspective view of a permanent magnet; FIG. 4 shows an electromagnet, a permanent magnet cooperating with the electromagnet, and a driving circuit the electromagnet; and FIG. 5 is a view for explaining how a pair of rotors rotate. BEST MODE OF CARRYING OUT THE INVENTION FIG. 1 shows a magnetic rotation apparatus embodying the present invention. The magnetic rotation apparatus has frame 1. Frame 1 is provided with a pair of rotation shafts 2 which extend vertically and in parallel to each other. Shafts 2 are located at a predetermined distance from each other. Upper and lower ends of each shaft 2 are rotationally supported on frame 1 via bearing 3. First rotor 4a is mounted on one of rotation shafts 2, second rotor 4b is mounted on the other rotation shaft 2. First and second rotors 4a and 4b are arranged on the same level. Rotors 4a and 4b have similar structures. For example, each rotor 4a (4b) comprises two ring-shaped plates 5 which are spaced apart from each other in the axial direction of the rotation shaft 2. Gears 6a and 6b made of synthetic resin are, as cooperating means, attached to lower surfaces of first and second rotors 4a and 4b. The diameters of gears 6a and 6b are identical but larger than those of rotors 4a and 4b. Gears 6a and 6b mesh with each other. First and second rotors 4a and 4b are thus rotatable in opposite directions in a cooperating manner. In FIG. 1, reference numeral 7 indicates support arms for supporting first and second rotors 4a and 4b.

For example, 16 magnets are arranged at regular intervals on a peripheral portion of first rotor 4a. These magnets are secured between two ring-shaped plates 5. In this embodiment, among the 16 magnets, one is electromagnet 9a (see FIG. 2), and the others are permanent magnets 8a. FIG. 2 shows only some of permanent magnets 8a. As shown in FIG. 3, permanent magnet 8a comprises case 10, and a plurality of rod-like ferromagnetic members 11 housed in case 10. Ferromagnetic member 11 is, for example, a ferrite magnet. Ferromagnetic members 11 of each permanent magnet 8a are arranged such that ferromagnetic members 11 have the same polarity at one end. In first rotor 4a, for example, an N-polarity end portion of each permanent magnet 8a faces radially outward, and an S-polarity end portion of magnet 8a faces radially inward. As shown in FIG. 2, when each permanent magnet 8a is located between two shafts 2, angle C formed by longitudinal axis A of magnet 8a and imaginary line B connecting two shafts 2 is, for example, set to 30.degree. C. On the other hand, electromagnet 9a is, as shown in FIG. 4, constituted by U-shaped iron core 12, and coil 13 wound around core 12. Electromagnet 9a is arranged such that both N- and S-polarity end portions face radially outward of first rotor 4a, and the above-mentioned angle C is formed, similarly to the case of permanent magnet 8a. The same number of permanent magnets (8b,9b) as the total number of all permanent magnets and electromagnet (8a,9a) of first rotor 4a are secured on a peripheral portion of second rotor 4b at regular intervals. In FIG. 2, when first and second rotors 4a and 4b are rotated in opposite directions, each permanent magnet of second rotor 4b periodically moves toward and away from the corresponding one of the magnets (8a,9a) of first rotor 4a. The permanent magnets (8b,9b) of second rotor 4b will now be described in greater detail. Permanent magnets 8b of second rotor 4b, which periodically move toward and away from permanent magnets 8a of first rotor 4a in accordance with the rotation of rotors 4a and 4b, have a structure similar to that of permanent magnets 8a of first rotor 4a. The polarity of that end portion of each permanent magnet 8b which is located radially outward from second rotor 4b, is identical with that of the end portion of each permanent magnet 8a of first rotor 4a. That is, the radially outward portion of each permanent magnet 8b has an N-polarity. Permanent magnet 9b of second rotor 4b, which periodically moves toward and away from electromagnet 9a of first rotor 4a, has a structure shown in FIG. 4. Permanent magnet 9b has a structure similar to that of permanent magnets 8a. Both polarities of electromagnet 9a face radially outward from first rotor 4a. Permanent magnet 9b has two different polarities which face radially outward from second rotor 4b and correspond to both polarities of electromagnet 9a. As shown in FIG. 2, when each permanent magnet 8b,9b is located between two rotation shafts 2, angle E formed by longitudinal axis D of the magnet (8b,9b) and imaginary line B connecting two shafts 2 is, for example, set to 56.degree. C. In addition, when rotors 4a and 4b are rotated in opposite directions, as shown by arrows, the magnets (8a,9a) of first rotor 4a move a little ahead of the corresponding permanent magnets (8b,9b) of second rotor 4b, in a region in which both magnets (8a,9a; 8b,9b) approach one another. In other words, the phase of rotation of the magnets (8a,9a) of first rotor 4a advances by a predetermined angle in relation to the permanent magnets (8b,9b) of second rotor 4b. As shown in FIG. 4, electromagnet 9a of first rotor 4a is electrically connected to drive circuit 14. Drive circuit 14 includes a power source for supplying an electric current to coil 13 of electromagnet 9a. While rotors 4a and 4b rotate, drive circuit turns on electromagnet 9a upon receiving a signal from first sensor 15 only when electromagnet 9a and permanent magnet 9b are in a first region in which they periodically approach each other. First sensor 15 is an optical sensor comprising a light-emitting element and a light-receiving element. As shown in FIG. 1, first sensor 15 is attached to a portion of frame 1 above first rotor 4a. First sensor 15 emits light in a downward direction. The light is reflected by reflection plate 16 projecting radially inward from the inner edge of first rotor 4a. First sensor 15 receives the reflected light, and feeds a signal to drive circuit 14. Thus, drive circuit 14 turns on electromagnet 9a. The circumferential length of reflection plate 16 is equal to that of the above-mentioned first region. When magnets 9a and 9b enter the first region, first sensor 15 is turned on, and when they leave the first region, first sensor 15 is turned off. When drive circuit 14 receives a signal from first sensor 15, it excites electromagnet 9a such that both polarities of electromagnet 9a correspond to those of permanent magnet 9b of second rotor 4b. Drive circuit 14 is electrically connected to switching circuit 17. When brake switch 18 is operated, switching circuit 17 reverses the direction in which an electric current is supplied to electromagnet 9a. When the current supplying direction of drive circuit 14 is reversed, drive circuit 14 excites electromagnet 9a only in a time period in which drive circuit 14 receives a signal from second sensor 19. Second sensor 19 has a structure similar to that of first sensor 15, and is attached to frame 1 so as to be located closer to the center of rotor 4a than first sensor 15. Reflection plate 20, which corresponds to the position of second sensor 19, is formed integral to an inner edge portion of reflection plate 16. As shown in FIG. 2, compared to reflection plate 16, reflection plate 20 extends in rotational direction of first rotor 4a, indicated by the arrow. The operation of the above-described magnetic rotation apparatus will now be explained with reference to FIG. 5. In FIG. 5, rotation shaft 2 of first rotor 4a is denoted by 01, and rotation shaft 2 of second rotor 4b is denoted by 02. Only the radially outward polarity, that is, N-polarity, of the magnets of rotors 4a and 4b is shown, for the sake of convenience. Although electromagnet 9a and permanent magnet 9b have both polarities located radially outward, only the N-polarity thereof is shown. When first and second rotors 4a and 4b are put in a position shown in FIG. 5, magnetic pole Nb1 of one permanent magnet of second rotor 4b is located in a line connecting shafts 01 and 02. In this case, polarity Na1 of first rotor 4a, which is paired with polarity Nb1, is a little advanced from polarity Nb1 in the rotational direction of first rotor 4a. For example, as shown in FIG. 5, magnetic pole Na1 is advanced from polarity Nb1 by an angle of X.degree.. Polarities Na1 and Nb1 exert repulsion force F1 upon each other along line L. Supposing that an angle, formed by line M, which is drawn from shaft 01 perpendicularly to line L, and the line connecting shafts 01 and 02 is represented by Y, and that the length of line K is represented by R, torques Ta1 and Tb1 caused by repulsion force F1 to rotate first and second rotors 4a and 4b can be given by: Ta1=F1.multidot.R.multidot.cos (Y-X)

Tb1=F1.multidot.R.multidot.cos Y Since cos (Y-X)>cos Y, Ta1>Tb1.

As shown in FIG. 5, since magnetic pole Na1 is advanced from magnetic pole Nb1 by angle X.degree., first rotor 4a receives a greater torque than second rotor 4b. Thus, first rotor 4a forwardly rotates in the direction of the arrow in FIG. 5. Mention is now made of paired magnets of rotors 4a and 4b in the vicinity of magnetic poles Na1 and Nb1. Magnetic poles Nan and Nan-1 of first rotor 4a are advanced ahead of magnetic pole Nal in the rotational direction. Magnetic poles Nan and Nan-1 receive a torque produced by a repulsion force acting between magnetic poles Nan and Nan-1 and corresponding magnetic poles Nbn and Nbn-1. In FIG. 5, magnetic poles Nan and Nan-1 receive a smaller torque, as they rotate farther from the location of magnetic pole Na1. It is well known that a torque of first rotor 4a, which is caused by a repulsion force acting on magnetic poles Nan and Nan-1, is decreased in inverse proportion to the square of the distance between paired magnetic poles Na and Nb.

Magnetic poles Na2 and Na3, behind magnetic pole Na1, receive a torque which tends to rotate rotor 4a in the reverse direction. This torque is considered to be counterbalanced with the torque acting on magnetic poles Nan and Nan-1. In FIG. 5, attention should be paid to the region of magnetic poles Na1 and Na2. As first rotor 4a forwardly rotates, the direction in which a torque applies to magnetic pole Na2, is changed from the reverse direction to the forward direction, before magnetic pole Na2 reaches the position of magnetic pole Na1. The torque for forwardly rotating rotor 4a is larger than that for reversely rotating rotor 4a. Therefore, first rotor 4a is easily rotated in the direction shown in FIG. 2. Second rotor 4b is considered to receive a torque in a direction reverse to the direction shown in FIG. 2, as seen from the description of first rotor 4a. It is obvious that second rotor 4b receives a maximum torque at the position of magnetic pole Nb1. As seen from the above formula, torque Tb1 applied to second rotor 4b in a direction reverse to that denoted by the arrow is smaller than torque Ta1 applied to first rotor 4a in the forward direction. The rotation of first rotor 4a is transmitted to second rotor 4b through gears 6a and 6b. By determining the relationship between the strengths of torques Ta1 and Tb1, second rotor 4b is thus rotated in a direction reverse to the rotational direction of first rotor 4a, against the torque applied to second rotor in the direction. As a result, first and second rotors 4a and 4b are kept rotating, since a torque for rotating rotors 4a and 4b in a cooperating manner is produced each time magnetic poles Na of first rotor 4a pass across the line connecting shafts 01 and 02. In a diagram shown in the right part of FIG. 5, a solid line indicates a torque applied to first rotor 4a, and a broken line indicates a torque applied to second rotor 4b. The ordinate indicates a distance between each magnetic pole and the line connecting shafts 01 and 02 of rotors 4a and 4b. The first region in which electromagnet 9a of first rotor 4a is turned on is set in a range of Z during which a torque is applied to first rotor 4a in the forward direction. In order to stop the cooperative rotation of rotors 4a and 4b, brake switch is turned on to operate switching circuit 17. Thus, the direction in which drive circuit 14 supplies a current to electromagnet 9a is reversed. The polarities of electromagnet 9a are reversed. The torque applied to electromagnet 9a in the forward direction is stopped. When electromagnet 9a approaches permanent magnet 9b, a magnetic attract:on force is produced. As a result, the rotation of rotors 4a and 4b is effectively slowed down and stopped. Since the second region, in which electromagnet 9a is excited, is larger than the first region, a large braking force can be obtained from a magnetic attraction force. In the above embodiment, since electromagnet 9a is excited only in a specific region, a large electric power is not required. In addition, since electromagnet 9a rotates and brakes rotors 4a and 4b, a braking mechanism for a magnetic rotation apparatus can be obtained without having to make the entire structure of the apparatus complex. The present invention is not restricted to the above embodiment. With the exception of the paired electromagnet and permanent magnet, all permanent magnets of the rotors are arranged such that their end portions of the same polarity face radially outward from the rotors. However, it is possible that the polarities of the radially outward end portions of the permanent magnets are alternately changed. Namely, it should suffice if the polarities of the radially outward end portions of the first rotor are identical to those of the corresponding radially outward end portions of the second rotor. The magnets may have different magnetic forces. Furthermore, an electric power for exciting the electromagnet can be derived from the rotation of the rotors or from the revolving magnetic field of the permanent magnet.

Angles C and E are not restricted to 30.degree. and 56.degree.. They may be freely determined in consideration of the strength of the magnetic force of the permanent magnet, a minimum distance between adjacent magnets, angle x, and the like. The number of magnets of the rotor is also freely chosen.

Industrial Applicability ~ As described above, the magnetic rotation apparatus of the present invention can be used as a driving source in place of an electric motor, and as an electric generator. US Patent # 5,594,289 (Cl. 310/152) Magnetic Rotating Apparatus (January 14, 1997) Kohei Minato Abstract --- On a rotor which is fixed to a rotatable rotating shaft, a plurality of permanent magnets are disposed along the direction of rotation such that the same magnetic pole type thereof face outward. In the same way, balancers are disposed on the rotor for balancing the rotation of this rotor. Each of the permanent magnets is obliquely arranged with respect to the radial direction line of the rotor. At the outer periphery of the rotor, an electromagnet is disposed facing this rotor, with this electromagnet intermittently energized based on the rotation of the rotor. According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets. This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets. Claims --- [ Claims not included here ] Description BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic rotating apparatus, and more particularly, to a magnetic rotating apparatus which utilizes repulsive forces produced between a permanent magnet and an electromagnet.

2. Description of the Prior Art In a conventional electric motor, an armature as a rotor consists of turns of wires, and electric field as a stator consists of a permanent magnet. In such the conventional electric motor, however, current must be usually supplied to windings of the armature which is rotated. When the current is supplied, heat is generated, which gives rise to the problem that not much driving force is efficiently generated. This, in turn, gives wise to the problem that the magnetic forces cannot be efficiently obtained from the permanent magnet. In addition, in the conventional electric motor, since the armature is so constructed as consisting of the windings, the moment of inertia cannot be made very high, so that enough torque cannot be obtained. To overcome the above-described problems of such the conventional electric motor, the inventor proposed, in Japanese Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486) a magnetic rotating apparatus in which a plurality of the permanent magnets are disposed along the two rotors, respectively, at a predetermined angle, and in which an electromagnet is disposed at one of the rotors. In a generally constructed conventional electric motor, there is a limit as to how much the efficiency of energy conversion can be increased. In addition, the torque of the electric motor cannot be made high enough. For the above reasons, hitherto, various improvements have been made on existing electric motors, without any success in producing an electric motor so constructed has providing satisfactory characteristics. In the magnetic rotating apparatus disclosed in Japanese Patent Publication No. 6868/1993 (U.S. Pat. No. 4,751,486) a pair of rotors is rotated. Therefore, it is necessary for each of the rotors to have high precision, and in addition, measures must be taken for easier rotation control. SUMMARY OF THE INVENTION In view of the above-described problems, the object of the present invention is to provide a magnetic rotating apparatus in which rotational energy can be efficiently obtained from the permanent magnet with a minimum amount of electrical energy, and in which rotation control can be carried out relatively easily. According to one aspect of the present invention, there is provided a magnetic rotating apparatus comprising a rotating shaft; a rotor which is fixed to the rotating shaft and which has disposed thereon permanent magnet means and means for balancing rotation, the permanent magnet means being disposed such that a plurality of magnetic poles of one (or first) polarity type is arranged along an outer peripheral surface in the direction of rotation, and a plurality of magnetic poles of the other (or second) polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; electromagnet means, which is disposed facing this rotor, for developing a magnetic field which faces the magnetic field of the permanent magnet means of the rotor and detecting means for detecting rotating position of the rotor to allow the electromagnet means to be energized. According to another aspect of the present invention, there is provided a magnetic rotating apparatus comprising a rotating shaft a rotor which is fixed to the rotating shaft and which has disposed thereon a plurality of permanent magnets and balancers for balancing rotation, the permanent magnets being disposed such that one magnetic polarity type is arranged along an outer peripheral surface in the direction of rotation and the other magnetic polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; an electromagnet, which is disposed facing this rotor, for developing a magnetic field which produces the other magnetic polarity type on the facing surface; and energizing means for intermittently energizing the electromagnet means from where the leading permanent magnet, based on the rotation of the rotor, passes the facing surface of the electromagnet in the direction of rotation. According to still another aspect of the present invention, there is provided magnetic rotating apparatus comprising a rotating shaft; a first rotor which is fixed to the rotating shaft and which has disposed thereon permanent magnet means and means for balancing rotation, the permanent magnet means being disposed such that a plurality of magnetic poles of the second polarity type is arranged along an outer peripheral surface in the direction of rotation, and a plurality of magnetic poles of the first pole type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; a second rotor which rotates along with the first rotor and is fixed to the rotating shaft, having disposed thereon a plurality of permanent magnets and balancers for balancing rotation, the permanent magnets being disposed such that one magnetic polarity type is arranged along an outer peripheral surface in the direction of rotation and the other magnetic polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line a first and a second electromagnet means, which are magnetically connected and disposed facing the first and second rotors, respectively, for developing a magnetic field which faces the magnetic field of the permanent magnet means of the first and second rotors; and detecting means for detecting rotating position of the rotors to allow the electromagnet means to be energized. The nature, principle and utility of the invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings: FIG. 1 is a perspective view schematically illustrating a magnetic rating apparatus according to one embodiment of the present invention FIG. 2 is a side view of the magnetic rotating apparatus illustrated in FIG. 1; FIG. 3 is a plan view of a rotor of the magnetic rotating apparatus illustrated in FIGS. 1 and 2;

FIG. 4 is a circuit diagram illustrating a circuit in the magnetic rotating apparatus shown in FIG. 1; FIG. 5 is a plan view showing a magnetic field distribution formed between the rotor and the electromagnet of the magnetic rotating apparatus shown in FIGS. 1 and 2, and FIG. 6 is an explanatory view illustrating a torque which causes rotation of the rotor of the magnetic rotating apparatus shown in FIGS. 1 and 2. DESCRIPTION OF THE PREFERRED EMBODIMENTS The magnetic field developed by an electromagnet means and that of a permanent magnet means of a rotor repel each other. In addition, the magnetic field of the permanent magnet means is flattened by the magnetic fields of other nearby permanent magnets and electromagnet means. Therefore, a torque is produced therebetween to efficiently rotate the rotor. Since the rotor has a high inertial force, when the rotor starts rotating, its speed increases by the inertial force and the turning force. A magnetic rotating apparatus related to one embodiment of the present invention will be described with reference to the following drawings. FIGS. 1 and 2 are schematic diagrams of a magnetic rotating apparatus related to one embodiment of the present invention. In the specification, the term "magnetic rotating apparatus" will include an electric motor, and from its general meaning of obtaining turning force from the magnetic forces of permanent magnets, it will refer to a rotating apparatus utilizing the magnetic forces. As shown in FIG. 1, in the magnetic rotating apparatus related to one embodiment of the present invention, a rotating shaft 4 is rotatably fixed to a frame 2 with bearings 5. To the rotating shaft 4, there are fixed a first magnet rotor 6 and a second magnet rotor 8, both of which produce turning forces and a rotated body 10, which has mounted therealong a plurality of rod-shaped magnets 9 for obtaining the turning forces as energy. They are fixed in such a manner as to be rotatable with the rotating shaft 4. At the first and second magnet rotors 6 and 8, there are provided, as will be described later in detail with reference to FIGS. 1 and 2, a first electromagnet 12 and a second electromagnet 14 respectively are energized in synchronism with rotations of the first and second magnet rotors 6 and 8, both of which face each other and are each disposed in a magnetic gap. The first and second electromagnets 12 and 14 are respectively mounted to a yoke 16, which forms a magnetic path. As shown in FIG. 3, the first and second magnet rotors 6 and 8 each have disposed on its disk-shaped surface a plurality of tabular magnets 22A through 22H for developing a magnetic field for generating the turning forces and balancers 20A through 20H, made of non-magnetic substances, for balancing the magnet rotors 6 and 8. In the embodiments, the first and second magnet rotors 6 and 8 each have disposed along the disk-shaped surface 24 at equal intervals the eight tabular magnets 22A through 22H along half of the outer peripheral area and +the eight balancers 20A through 20H along the other half of the outer peripheral area.

As shown in FIG. 3, each of the tabular magnets 22A through 22H are disposed so that its longitudinal axis 1 makes an angle D with respect to a radial axis line 11 of the disk-shaped surface 24. In the embodiment, an angle of 30 degrees and 56 degrees have been confirmed for the angle D. An appropriate angle, however, can be set depending on the radius of the disk-shaped surface 24 and the number of tabular magnets 22A through 22H to be disposed on the disk-shaped surface 24. As illustrated in FIG. 2, from the viewpoint of effective use of the magnetic field, it is preferable that the tabular magnets 22A through 22H on the first magnet rotor 6 are positioned so that their N-poles point outward, while the tabular magnets 22A through 22H on the second magnet rotor 8 are positioned so that their S-poles point outward. Exterior to the first and second magnet rotors 6 and 8, the first and second electromagnets 12 and 14 are disposed facing the first and second magnet rotors 6 and 8 respectively in the magnetic gap. When the first and second electromagnets 12 and 14 are energized, they develop a magnetic field identical in polarity to the their respective tabular magnets 22A through 22H so that they repel one anther. In other words, as shown in FIG. 2, since the tabular magnets 22A through 22H on the first magnet rotor 6 have their N-poles facing outwards, the first electromagnet 12 is energized so that the side facing the first magnet rotor 6 develops an N-polarity. In a similar way, since the tabular magnets 22A through 22H on the second magnet rotor 8 have their S-poles facing outwards, the second electromagnet 14 is energized so that the side facing the tabular magnets 22A through 22H develops a S-polarity. The first and second electromagnets 12 and 14, which are magnetically connected by the yoke 16, are magnetized so that the sides facing their respective magnet rotors 6 and 8 are opposite in polarity with respect to each other. This means that the magnetic fields of the electromagnets 12 and 14 can be used efficiently. A detector 30, such as microswitch, is provided to either one of the first magnet rotor 6 or second magnet rotor 8 to detect the rotating position of the magnet rotors 6 and 8. That is, as shown in FIG. 3, in a rotational direction 32 of the tabular magnets 22A through 22H, the first and the second magnet rotors 6 and 8 are respectively energized when the leading tabular 22A has passed. In other words, in the rotational direction 32, the electromagnet 12 or 14 is energized when starting point So, located between the leading tabular magnet 22A and the following tabular magnet 22B coincides with the center point Ro of either the electromagnet 12 or 14. In addition, as illustrated in FIG. 3, in the rotational direction 32 of the tabular magnets 22A through 22H, the first and the second magnet rotors 6 and 8 are de-energized when the last tabular magnet 22A has passed. In the embodiment, an end point Eo is set symmetrical to the starting point So on the rotating disk-shaped surface 24. When the end point Eo coincides with the center point Ro of either the electromagnet 12 or 14, the electromagnet 12 or 14 is de-energized, respectively. As will be described later, with the center point Ro of the electromagnet 12 or 14 arbitrarily set between the starting point So and the end point Eo, the magnet rotors 6 and 8 start to rotate when the electromagnets 12 and 14 and their tabular magnets 22A through 22H face one another. When a microswitch is used as the detector 30 for detecting the rotating position, the contact point of the microswitch is allowed to slide along the surface of the rotating disk-shaped surface 24. A step is provided for the starting point So and the end point Eo so that the contact of the microswitch closes between the starting point So and the end point Eo. The area along the periphery therebetween protrudes beyond the other peripheral areas of the rotating disk-shaped surface 24. It is apparent that a photo sensor or the like may be used instead of the microswitch as the detector 30 for detecting the rotating position. As shown in FIG. 4, the windings of the electromagnets 12 and 14 are connected to a DC power source 42 through a movable contact of a relay 40, which is connected in series with the windings. A series circuit containing the relay 40 (solenoid) and the detector 30 or microswitch is connected to the DC power source 42. In addition, from the viewpoint of energy conservation, a charger 44 such as a solar cell is connected to the DC power source 42. It is preferable that the DC power source 42 is constantly chargeable using solar energy or the like. In the magnetic rotating apparatus illustrated in FIGS. 1 and 2, a magnetic field distribution shown in FIG. 5 is formed between the tabular magnets 22A through 22H, disposed on each of the magnet rotors 6 and 8, and the electromagnets 12 and 14 which face them, respectively. When the electromagnet 12 or 14 is energized, a magnetic field of a tabular magnet of the tabular magnets 22A through 22H, adjacent to the electromagnet 12 or 14, is distorted in the longitudinal direction in correspondence with the rotational direction. This results in the generation of a repulsive force therebetween. As is apparent from the distortion of the magnetic field, the repulsive force has a larger component in the longitudinal or perpendicular direction, and produces a torque, as shown by an arrow 32. Similarly, a magnetic field of a tabular magnet of the tabular magnets 22A through 22H, which next enters the magnetic field of the electromagnet 12 or 14, is distorted. the repulsive force produced between the tabular magnets of the tabular magnets 22A through 22H, which have already entered the magnetic field of the electromagnets, a repulsive force operates between both of the poles M and M' of the tabular magnet at the rotating side and the electromagnet at the stationary side, respectively. Therefore, from the relationship illustrated in FIG. 6, an angular torque T is generated based on the formula: T=F. a.cos (.alpha.-.beta.), where in a is a constant. The angular torque starts the rotation of the rotating disk-shaped surface 24. After the rotating disk-shaped surface 24 has started rotating, its rotating speed gradually increases due to an inertial moment thereof, which allows a large turning driving force to be produced. After a stable rotation of the rotating disk-shaped surface 24 has been produced, when a necessary electromotive force can be developed in an electromagnetic coil (not illustrated) by externally bringing it near a rotated body 10 to be rotated along with the rotating disk-shaped surface 24. This electric power can be used for other applications. This rotating principle is based on the rotating principle of the magnetic rotating apparatus already disclosed in Japanese Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486) by the inventor. That is, even if an electromagnet, provided for one of the rotors of the magnetic rotating apparatus disclosed in the same Patent Application, is fixed, it is rotated in accordance with the rotating principle disclosed therein. For details, refer to the above Japanese Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486).

The number of tabular magnets 22A through 22H is not limited to "8" as shown in FIGS. 1 and 3. Any number of magnets may be used. In the above-described embodiment, although the tabular magnets 22A through 22H are disposed along half of the peripheral area of the disk-shaped surface 24, and the balancers 20A through 20H are disposed along the other half of the peripheral area, the tabular magnets may further be disposed along other areas of the disk-shaped surface 24. It is preferable that balancers, in addition to magnets, are provided along a portion of the peripheral area on the disk-shaped surface. The counter weights, which do not need to be formed into separate blocks, may be formed into one sheet of plate which extends on the outer peripheral area of the disk-shaped surface. In addition, in the above-described embodiments, while the construction is such as to allow the electromagnets to be energized for a predetermined period of time for every rotation of the rotating disk-shaped surface, the circuit may be so constructed as to allow, upon increased number of rotations, energization of the electromagnets for every rotation of the rotating disk-shaped surface, starting from its second rotation onwards. Further, in the above-described embodiment, a tabular magnet has been used for the permanent magnet, but other types of permanent magnets may also be used. In effect, any type of magnet may be used as the permanent magnet means as long as a plurality of magnetic poles of one type is disposed along the outer surface of the inner periphery and a plurality of magnetic poles of the other type are disposed along the inner peripheral surface of the disk-shaped surface, so that a pair of corresponding magnetic poles of one and the other polarities is obliquely arranged, with respect to the radial line 11, as shown in FIG. 3. Although the tabular magnets 22A through 22H are mounted on the magnet rotors 6 and 8 in the above embodiment, they may be electromagnets. In this case, the electromagnets 12 and 14 may be the alternative of electromagnets or permanent magnets.

According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets. This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets. It should be understood that many modifications and adaptations of the invention will become apparent to those skilled in the art and it is intended to encompass such obvious modifications and changes in the scope of the claims appended hereto. KeelyNet: BBS Posting from Henry Curtis (11-18-1997)

Korean Magnetic Perpetual Motion Wheel I must apologize for not having all the details of this interesting device but will update the file when I get more info from the source. In email communications with John Schnurer, I happened to mention it and he's been on me since then to send him a diagram, yet I felt like it would simply be confusing because its operation is not clear or readily apparent from the information I had.The information that I have comes directly from long time friend Henry Curtis of Colorado. We both attended the 1997 ISNE conference in Denver and Henry was telling about this interesting machine he had seen while on a trip to the Phillipines. He said there was a free energy conference held there and he noticed a spinning bicycle wheel that was attached to a stand that sat on a table.The wheel was running when he first saw it, yet there did not appear to be any driving force such as a motor, belts, gears, etc..Henry said he watched it for quite awhile and it never stopped running. On expressing curiosity about the wheel, he was invited to stop it and start it up without any outside assistance.Henry reports the wheel was brought to a complete stop, then he gave it a spin with his hand and it began moving on its own. I am uncertain if it followed the tendency of other such devices to establish its own speed. Some devices like this can be spun up to high speed from an outside source, then will slow to a speed which is determined by the geometry and strength of the repelling or attracting forces that operate it.Henry swears it was the neatest thing he'd ever seen and drew a crude diagram of the arrangement on my notepad. Unfortunately, we were a bit rushed and I did not achieve a complete understanding of how it operated. That is why I did not want to blow smoke about it until more detail had been received, god knows, we don't need any more of that.However, perhaps someone can figure it out from the limited information I do have. The following drawing shows the wheel arrangement, one half was weighted, the other half had slanted magnets. I do not know whether they are all repelling, attracting or a mix of these forces. As you can imagine, the weight of the magnets must equal the weight of the other half of the wheel to balance out. Apparently the force of the magnetic repulsion or attaction provides the actual imbalance.Henry also said there was a patent on this device that is dated January 14, 1997. The inventor is a Japanese man named Minatu. The spelling of this name is uncertain. I did a search on the IBM server but found nothing even remote. Henry specifically said this was a United States patent. So, here it is. Perhaps Henry can come up with some more detail which can be used to update this file in future. Good luck.... KeelyNet: Update and Corrections from Henry Curtis (Wed, 19 Nov 1997) ~

From: Henry Curtis ~ To: Jerry Decker Subject: Bicycle wheel correction and update Jerry, Again we see that communication is difficult and memories are fallable. Obviously I am remiss in not having sent this to you months ago as I intended to, but as a sage of old observed "The spirit is willing, but the flesh is slow." During the first weekend of May, 1997, a group in Soeul, Korea headed up by Mr. Chi San Park, held The First International New Energy Conference in Seoul, Korea. I attended this conference and gave a talk on various approcahes to free energy. It was at this conference in Seoul, Korea that I saw the bicycle wheel and had the opportunity to work with it unattended by anyone else.The inventor is Kohei Minato, a Japanese rock musician, who reports that he has spent a million dollars out of his own pocket developing magnetic motors, because the world needs a better source of energy. He has several patents in various countries. His latest patent that I am aware of is United States Patent # 5,594,289. His development efforts have gone in the general direction of the Adams motor which the above patent is similar to. He had a working prototype of this design at the conference and reported that it used 150 watts power input and produced 450 watts output on a sustained basis. About a year ago CNN (in the US) had a 10 minute segment about him and his motors. In this video he is shown demonstrating two of his magnetic motors. I have a copy of this film clip that he gave to me. I will make a copy and send it to you. Unfortunately, the editors were not attuned to technical details and the pictures of the running machines show little useful detail. The Phillipine connection that you mention is completely erroneous. It was in Korea. The drawing on the web site is essentially correct with the following exceptions. The counter weight is a single curved piece of aluminum covering 180 degrees. Each of the several individual magnets on the other half of the wheel are slightly asymmetric, crescent shaped and nested. They are magnetised end to end with the N poles out. The motor is actuated by moving the N pole of a large permanet magnet (the drive magnet) toward the wheel. As this magnet is moved toward the wheel, the wheel starts to spin. As the magnet is moved closer to the wheel it spins faster. The acceleration of the wheel is rapid. So rapid in fact, as to be startling. To put it another way I was very impressed. The motor works. And it works very well. In the film clip a slight pumping action of Minato's hand holding the magnet is apparent. When I braced my hand so that there was no pumping action, the motor still ran. In fact it seemed to run better. Pumping action by the hand held magnet is not the power that drives the motor. When the drive magnet is moved away from the wheel it coasts rather quickly to a stop and comes to rest in a manner typical of any spinning bicycle wheel. Again when the wheel is at rest and a large magnet is moved up to the wheel it starts to spin. At no time is it necessary to touch the wheel to get it to rotate. Simply bring the N pole of a large magnet several inches from the wheel. The particular orientation of the wheel when it is at rest seems to have no effect on how well it starts to turn. Irrespective of how the wheel and the magnets on it are sitting; move the drive magnet near, it starts to spin. Move the magnet closer it spins faster. Move the magnet further away it slows up. The wheel was mounted on a stand made of aluminum angle pieces bolted together similar to the diagram in the above mentioned patent. The axle of the wheel was mounted parellel to the surface of the planet. I have attached a rough diagram of the wheel. Apparently the geometry of the magnets on the wheel is very important and subtle. I have built several small models none of which have shown the free energy effects of Minato's machine. The conference in Seoul was attended by several hundred people, most appeared to be under 40 and evenly divided between men and women. Presenters were from Korea, US, Japan, and China. Simultaneous translation was provided for all talks in the 3 day conference. Jerry, I hope this information is useful. I may be contacted by e-mail at mailto:hcurtis@mindspring.com or by phone at 303.344.1458.

KeelyNet: Email from Gene Mallove at Infinite Energy ~ I spoke to Bob Vermillion of Tri-Cosmos Development (Los Angeles, CA 310-284-3250 or fax 310-284-3260) today, just before he left for the three-day demonstrations of the Minato magnetic motor being held in Mexico City, Mexico on July 8, 9, 10th.Three (3) Minato Motors (MM), covered by US Patents # 5,594,289 (Jan 14, 1997) and # 4,751,486 (June 14, 1988), have been brought over from Japan. One was allegedly tested last evening by Grupo Bufete Industrial (supposedly one of the largest power generation construction companies in Mexico and South America). The company engineers were said (by Vermillion) to have measured an output /input ratio of 4.3 / 1. The printed literature, which I received in a Fedex packet from Vermillion states that the device can put out 500 watts (maximum) with an input of 34 watts.For those of you who wonder why the device is not self-sustaining -- oral info from Vermillion is that Minato *will* in the course of one of the demonstrations *remove the battery power supply* and let the device self-run -- presumably with a load. The press release makes no bones about the physics-busting character of the MM: "As rotations per minute (rpm's) increase, the electromagnetic consumption of the stator decreases. This phenomenon is in direct conflict with accepted laws of physics and is achieved through the repelling magnetic fields. It operates without heat, noise, or pollution of any kind. It can be produced in size from ultra-small to very large." It is said in the press release that applications from cell phones to laptop computers are under development. Vermillion told me of other parties who were planning to attend the demonstrations, which will be conducted both in public displays and with private party measurements. These include: ENRON, Bechtel, Tejas (a division of Shell Oil Corporation), Fluor Daniels, Kellogg Corp. .He told me that Hal Fox of New Energy News and the Fusion Information Center will be there (I confirmed with Hal that he will be there and will give us a full report.) I considered going myself (I was invited), but I trust Hal Fox to provide a full report --

Fate Crashed off coast of New Jersey, 4 April 1933

 

USS Akron (ZRS-4) was a helium-filled rigid airship of the U.S. Navy, the lead ship of her class, which operated between September 1931 and April 1933. It was the world's first purpose-built flying aircraft carrier, carrying F9C Sparrowhawk fighter planes, which could be launched and recovered while it was in flight. With an overall length of 785 ft (239 m), Akron and her sister ship Macon were among the largest flying objects ever built. Although LZ 129 Hindenburg and LZ 130 Graf Zeppelin II were some 18 ft (5.5 m) longer and slightly more voluminous, the two German airships were filled with hydrogen, and so the two US Navy craft still hold the world record for the largest helium-filled airships.[2]

 

Akron was destroyed in a thunderstorm off the coast of New Jersey on the morning of 4 April 1933, killing 73 of the 76 crewmen and passengers. The accident involved the greatest loss of life in any airship crash.

Technical description

 

The airship's skeleton was built of the new lightweight alloy duralumin 17-SRT.[3] The frame introduced several novel features compared with traditional Zeppelin designs. Rather than being single-girder diamond trusses with radial wire bracing, the main rings of Akron were self-supporting deep frames: triangular Warren trusses 'curled' round to form a ring. Though much heavier than conventional rings, the deep rings promised to be much stronger, a significant attraction to the navy after the in-flight break up of the earlier conventional airships R38/ZR-2 and ZR-1 Shenandoah.[4] The inherent strength of these frames allowed the chief designer, Karl Arnstein, to dispense with the internal cruciform structure used by Zeppelin to support the fins of their ships. Instead, the fins of Akron were cantilevered: mounted entirely externally to the main structure.[5] Graf Zeppelin, Graf Zeppelin II, and Hindenburg used a supplementary axial keel along the hull centerline. However, the Akron used three keels, one running along the top of the hull and one each side, 45 degrees up from the lower centreline. Each keel provided a walkway running almost the entire length of the ship. The electric and telephone wiring, control cables, 110 fuel tanks, 44 water ballast bags, 8 engine rooms, engines, transmissions, and water-recovery devices were placed along the lower keels. The inert gas helium was used instead of flammable hydrogen, which improved streamlining by allowing the engines to be safely placed inside the hull. A generator room, with 2 Westinghouse d.c. generators powered by a 30-h.p. internal combustion engine, was forward of the No. 7 engine room.[6]: 36, 187–197 

 

The main rings were spaced at 22.5 m (74 ft) and between each pair were three intermediate rings of lighter construction. In keeping with conventional practice, 'station numbers' on the airship were measured in meters from zero at the rudder post, positive forward and negative aft. Thus the tip of the tail was at station −23.75 and the nose mooring spindle was at station 210.75. Each ring frame formed a polygon with 36 corners and these (and their associated longitudinal girders) were numbered from 1 (at the bottom centre) to 18 (at the top centre) port and starboard.[7] Thus a position on the hull could be referred to, for example, as "6 port at station 102.5" (the number 1 engine room).

 

While Germany, France and Britain used goldbeater's skin to gas-proof their gasbags, Akron used Goodyear Tire and Rubber's rubberised cotton, heavier but much cheaper and more durable. Half the gas cells used an experimental cotton-based fabric impregnated with a gelatin-latex compound. This was more expensive than the rubberised cotton but lighter than goldbeater's skin. It was so successful that all the gasbags of Macon were made from it.[8] There were 12 gas cells, numbered 0 to XI, using Roman numerals and starting from the tail.[9] While the 'air volume' of the hull was 7,401,260 cu ft (209,580 m3), the total volume of the gas cells at 100 percent fill was 6,850,000 cu ft (194,000 m3). At a normal 95 percent fill with helium of standard purity, the 6,500,000 cu ft (180,000 m3) of gas would yield a gross lift of 403,000 lb (183,000 kg). Given a structure deadweight of 242,356 lb (109,931 kg),[10] this gives a useful lift of 160,644 lb (72,867 kg) available for fuel, lubricants, ballast, crew, supplies and military load (including the skyhook airplanes)

 

Eight Maybach VL II 560 hp (420 kW) gasoline engines were mounted inside the hull.[11] Each engine turned a two-bladed, 16 ft 4 in (4.98 m) diameter, fixed pitch, wooden propeller via a driveshaft and bevel gearing which allowed the propeller to swivel from the vertical plane to the horizontal.[12] With the engines' ability to reverse, this allowed thrust to be applied forward, aft, up or down.[13] It appears from photographs that the four propellers on each side were contra-rotating, each one turning the opposite way to the one ahead of it. Thus it would appear that the designers were aware that running the propellers in the air disturbed by the one ahead was not ideal. While the external engine pods of other airships allowed the thrust lines to be staggered, placing all four engine rooms on each side of the ship along the lower keel resulted in Akron's propellers all being in line. This proved problematic in service, as it induced considerable vibration which was especially noticeable in the emergency control position in the lower fin. By 1933, Akron had two of her propellers replaced by more advanced, ground-adjustable, three-bladed, metal propellers.[14] These promised a performance increase and were adopted as standard for Macon.

 

The outer cover was of cotton cloth, treated with four coats of clear and two coats of aluminum pigmented cellulose dope. The total area of the skin was 330,000 sq ft (31,000 m2) and it weighed, after doping, 113,000 lb (51,000 kg).[15]

 

The prominent dark vertical bands on the hull were condensers of the system designed to recover water from the engines' exhaust for buoyancy compensation. In-flight fuel consumption continuously reduces an airship's weight and changes in the temperature of the lifting gas can do the same. Normally, expensive helium has to be released to compensate and any way of avoiding this is desirable. In theory, a water recovery system such as this can produce 1 lb of ballast water for every lb of fuel burned, though this is unlikely to be achieved in practice.[13]

 

Akron could carry up to 20,700 US gal (78,000 L) of gasoline (126,000 lb (57,000 kg)) in 110 separate tanks which were distributed along the lower keels to preserve the ship's trim, giving her a normal range of 5,940 nmi (6,840 mi; 11,000 km) at cruising speed.[16] Theoretical maximum ballast water capacity was 223,000 lb (101,000 kg) in 44 bags, again distributed along her length, though normal ballast load at unmasting was 20,000 lb (9,100 kg).[15] Maximum ballast was never an option, because a full fuel and ballast load would have left only 4,600 lb (2,100 kg) lifting capacity for aircraft, crew, and supplies, and each fully loaded F9C fighter alone weighed 2,800 lb (1,300 kg).

 

The heart of the ship, and her sole reason for existing, was the airplane hangar and trapeze system. Aft of the control car, in bay VII, between frames 125 and 141.25, was a compartment large enough to accommodate up to five F9C Sparrowhawk airplanes. However, two structural girders partially obstructed Akron's aftmost hangar bays, limiting its capacity to three airplanes (one in each forward corner of the hangar and one on the trapeze). A modification to remove this design flaw was pending at the time of the ship's loss.[17]

 

The F9C was not the ideal choice, being designed as a 'conventional' carrier-borne fighter. It was heavily built to withstand carrier landings, downward visibility was not very good and it initially lacked an effective radio. But the primary role of Akron's airplanes was long-range naval scouting. What was actually needed was a stable, fast, lightweight scouting airplane with a long range,[18] but none existed capable of fitting between the structural members and into the airship's hangar, as the F9C could.

 

The trapeze was lowered through the T-shaped door in the bottom of the ship and into the slipstream, with an airplane attached to the crossbar by the 'skyhook' above its top wing, its pilot on board and its engine running. The pilot tripped the hook and the airplane fell away from the ship. On his return, he positioned himself beneath the trapeze and climbed up until he could fly his skyhook onto the crossbar, at which point it automatically latched shut. Now, with the engine idling, the trapeze and airplane were raised into the hangar, the pilot cutting his engine as he passed through the door. Once inside, the airplane was transferred from the trapeze to a trolley, running on an overhead 'monorail' system by which it could be shunted into one of the four corners of the hangar to be refueled and re-armed. Having a single trapeze raised two problems: it limited the rate at which airplanes could be launched and recovered and any fault in the trapeze would leave any airborne scouts with nowhere to land. The solution was a second, fixed trapeze permanently rigged further aft along the bottom of the ship at station 102.5 and known as the 'perch'. By 1933 a perch was fitted and in use. Three more perches were planned (at stations 57.5, 80 and 147.5) but these were never fitted.[17]

 

Akron revived an idea used, and eventually rejected, by the German Navy zeppelins during World War I: the spähkorb or 'spy basket'.[19] The "angel basket" or "sub-cloud observation car", allowed the airship to remain hidden in a cloud layer, while still observing the enemy below. The small car, rather like an airplane fuselage without wings, could be lowered on a 1000 foot long cable. The observer on board communicated with the ship by telephone. In practice, the device was unstable, almost looping over the airship during its only test flight.[6]

 

During the design stage, in 1929, the navy requested an alteration to the fins. It was considered desirable for the bottom of the lower fin to be visible from the control car. Charles E. Rosendahl had witnessed, from the control room, Graf Zeppelin almost snagging her fin on high-tension power lines during her heavy take off into an unsuspected but very marked temperature inversion from Mines Field, Los Angeles at the start of the last leg of her round-the-world flight earlier that year.[20] The design change would also allow direct vision between the main control car and the emergency control position in the lower fin. The control car was moved 8 ft (2.4 m) aft and all the fins were shortened and deepened. The leading edge root of the fins no longer coincided with a main (deep) ring and instead the foremost attachment was now to an intermediate ring at frame 28.75. This achieved the required visibility, improved low-speed controllability, due to the increased span of the control surfaces, and simplified stress calculations, by reducing the number of fin attachment points. The designers and the navy's inspectors, led by the very experienced Charles P Burgess, were entirely satisfied with the revised stress calculations. However, this alteration has been the subject of much criticism as an "inherent defect" in the design and is often alleged to have been a major factor in the loss of Akron's sister ship Macon.[21] Construction for both ships amounted to $8,800,000 (in 1931 dollars) with the Akron accounting $5,538,400 of the total.[22]

Construction and commissioning

 

Construction of ZRS-4 was begun on 31 October 1929 at the Goodyear Airdock in Akron, Ohio by the Goodyear-Zeppelin Corporation.[23] Because it was larger than any airship previously built in the US, a special hangar was constructed.[24] Chief Designer Karl Arnstein and a team of experienced German airship engineers instructed and supported design and construction of both U.S. Navy airships USS Akron and USS Macon.[25]

 

On 7 November 1929, Rear Admiral William A. Moffett, the Chief of the U.S. Navy's Bureau of Aeronautics, drove the "golden rivet" into the main ring of "ZRS4". Erection of the hull sections began in March 1930. Secretary of the Navy Charles Francis Adams chose the name Akron (for the city near where it was being built), and Assistant Secretary of the Navy Ernest Lee Jahncke announced it in May 1930.[6]: 33

On 8 August 1931, Akron was launched (floated free of the hangar floor) and christened by First Lady Lou Henry Hoover, the wife of the President of the United States, Herbert Clark Hoover. The maiden flight of Akron took place around Cleveland on the afternoon of 23 September with Secretary of the Navy Adams and Rear Admiral Moffett on board. The airship made ten trial flights, including a 2000-mile journey, over 48 hours, to St. Louis, Chicago, and Milwaukee. On 21 October Akron left the Goodyear Zeppelin Air Dock for the Lakehurst Naval Air Station (NAS), with Lieutenant Commander Charles E. Rosendahl in command, arriving the next day. On Navy Day, 27 October 1931, the Akron was commissioned as a Navy vessel.[6]: 37–43

Maiden voyage

 

On 2 November 1931, Akron departed on her first cruise down the eastern seaboard to Washington, D.C. On 3 November the Akron took to the air with 207 persons on board. This demonstration was to prove that in an emergency airships could provide limited but high speed airlift of troops to outlying possessions. Over the weeks that followed, some 300 hours aloft were logged in a series of flights, including a 46-hour endurance flight to Mobile, Alabama, and back. The return leg of the trip was made via the valleys of the Mississippi River and the Ohio River.[6]: 47–49 

Participation in a search exercise (January 1932)

 

On the morning of 9 January 1932, Akron departed from Lakehurst to work with the Scouting Fleet on a search exercise. Proceeding to the coast of North Carolina, Akron headed out over the Atlantic where it was assigned to find a group of destroyers bound for Guantánamo Bay, Cuba. Once these were located, the airship was to shadow them and report their movements. Leaving the coast of North Carolina at about 7:21 on the morning of 10 January, the airship proceeded south, but bad weather prevented sighting the destroyers (contact with them was missed at 12:40 EST, although their crews had sighted Akron) and eventually shaped a course toward the Bahamas by late afternoon. Heading northwesterly into the night, Akron then changed course shortly before midnight and proceeded to the southeast. Ultimately, at 9:08 am on 11 January, the airship succeeded in spotting the light cruiser USS Raleigh and 12 destroyers, positively identifying them on the eastern horizon two minutes later. Sighting a second group of destroyers shortly thereafter, Akron was released from the evaluation about 10:00 a.m., having achieved a "qualified success" in the initial test with the Scouting Fleet, but the performance could have been better with radio detection finding equipment, and scout planes.[6]: 49–51 

 

As the historian Richard K Smith wrote in his definitive study, The Airships Akron and Macon, "...consideration given to the weather, duration of flight, a track of more than 3,000 mi (4,800 km) flown, her material deficiencies, and the rudimentary character of aerial navigation at that date, the Akron's performance was remarkable. There was not a military airplane in the world in 1932 which could have given the same performance, operating from the same base."[26]

First accident (February 1932)

 

Akron was to have taken part in Fleet Problem XIII, but an accident at Lakehurst on 22 February 1932 prevented her participation. While the airship was being taken from her hangar, the tail came loose from her moorings, was caught by the wind, and struck the ground.[27] The heaviest damage was confined to the lower fin area, which required repair. Also, ground handling fittings had been torn from the main frame, necessitating further repairs. Akron was not certified as airworthy again until later in the spring. Her next operation took place on 28 April, when it made a nine-hour flight with Rear Admiral Moffett and Secretary of the Navy Adams aboard.[6]: 53–55 

 

As a result of this accident, a turntable with a walking beam on tracks powered by electric mine locomotives was developed to secure the tail and turn the ship even in high winds so that it could be pulled into the massive hangar at Lakehurst.[28]

Testing of the "spy basket"

 

Soon after returning to Lakehurst to disembark her distinguished passengers, Akron took off again to conduct a test of the "spy basket"—something like a small airplane fuselage suspended beneath the airship that would enable an observer to serve as the ship's "eyes" below the clouds while the ship herself remained out of sight above them. The first time the basket was tried (with sandbags aboard instead of a man), it oscillated so violently that it put the whole ship in danger. The basket proved "frighteningly unstable", swooping from one side of the airship to the other before the startled gaze of Akron's officers and men and reaching as high as the ship's equator.[19] Though it was later improved by adding a ventral stabilizing fin, the spybasket was never used again.[29]

 

Akron and Macon (which was still under construction) were regarded as potential "flying aircraft carriers", carrying parasite fighters for reconnaissance. On 3 May 1932, Akron cruised over the coast of New Jersey with Rear Admiral George C. Day, and the Board of Inspection and Survey, on board, and for the first time tested the "trapeze" installation for in-flight handling of aircraft. The aviators who carried out those historic "landings"—first with a Consolidated N2Y trainer and then with the prototype Curtiss XF9C-1 Sparrowhawk—were Lieutenant D. Ward Harrigan and Lieutenant Howard L. Young. The following day, Akron carried out another demonstration flight, this time with members of the House Committee on Naval Affairs on board; this time, Lieutenants Harrigan and Young gave the lawmakers a demonstration of Akron's aircraft hook-on ability.[6]: 55–56 

 

Following the conclusion of those trial flights, Akron departed from Lakehurst, New Jersey on 8 May 1932, for the American west coast. The airship proceeded down the eastern seaboard to Georgia and then across the southern gulf states, continuing over Texas and Arizona. En route to Sunnyvale, California, Akron reached Camp Kearny in San Diego on the morning of 11 May and attempted to moor. Since neither trained ground handlers nor specialized mooring equipment were present, the landing at Camp Kearny was fraught with danger. By the time the crew started the evaluation, the helium gas had been warmed by sunlight, increasing lift. Lightened by 40 short tons (36 t), the amount of fuel spent during the transcontinental trip, Akron was now uncontrollably light.[6]: 56–57 

 

The mooring cable was cut to avert a catastrophic nose-stand by the errant airship which floated upwards. Most of the mooring crew—predominantly "boot" seamen from the Naval Training Station San Diego—released their lines although four did not. One let go at about 15 ft (4.6 m) and suffered a broken arm while the three others were carried further aloft. Of these, Aviation Carpenter's Mate 3rd Class Robert H. Edsall and Apprentice Seaman Nigel M. Henton soon plunged to their deaths while Apprentice Seaman C. M. "Bud" Cowart held on to his line and then secured himself to it[30] before being hoisted on board the airship an hour later.[31] Akron moored at Camp Kearny later that day before proceeding to Sunnyvale, California. Footage from the accident appears in the film Encounters with Disaster, released in 1979 and produced by Sun Classic Pictures.

West Coast flights

 

Over the weeks that followed, Akron "showed the flag" on the West Coast of the United States, ranging as far north as the Canada–US border before returning south in time to exercise once more with the Scouting Fleet. Serving as part of the "Green Force", the Akron attempted to locate the "White Force". Although opposed by Vought O2U Corsair floatplanes from "enemy" warships, the airship located the opposing forces in just 22 hours, a fact not lost upon some of the participants in the exercise in subsequent critiques.[6]: 58–59 

 

In need of repairs, Akron departed from Sunnyvale on 11 June 1932 bound for Lakehurst, New Jersey, on a return trip that was sprinkled with difficulties, mostly because of unfavorable weather, and having to fly at pressure height while crossing the mountains. Akron arrived on 15 June after a "long and sometimes harrowing" aerial voyage.[6]: 61–62 

 

Akron next underwent a period of voyage repairs before taking part in July in a search for Curlew, a yacht which had failed to reach port at the end of a race to the island of Bermuda. The yacht was later discovered safe off Nantucket.[32] It then resumed operations capturing aircraft on the "trapeze" equipment. Admiral Moffett again boarded Akron on 20 July, but the next day left the airship in one of her N2Y-1s which took him back to Lakehurst after a severe storm had delayed the airship's own return to base.[6]: 65–66 

Further tests as "flying aircraft carrier"

 

Akron entered a new phase of her career that summer of 1932, engaging in intense experimentation with the revolutionary "trapeze" and a full complement of F9C-2s. A key element of the entrance into that new phase was a new commanding officer, Commander Alger Dresel.[6]: 63–65 

Third accident (August 1932)

 

Another accident hampered training on 22 August when Akron's tail fin became fouled by a beam in Lakehurst's massive Hangar No 1 after a premature order to commence towing the ship out of the mooring circle. Nevertheless, rapid repairs enabled eight more flights over the Atlantic during the last three months of 1932. These operations involved intensive work with the trapeze and the F9C-2s, as well as the drilling of lookouts and gun crews.[6]: 66–67 

 

Among the tasks undertaken were the maintenance of two aircraft patrolling and scouting on Akron's flanks. During a seven-hour period on 18 November 1932, the airship and a trio of planes searched a sector 100 mi wide.[6]: 67 

Return to the fleet

 

After local operations out of Lakehurst for the remainder of 1932, Akron was ready to resume operations with the fleet. On the afternoon of 3 January 1933, Commander Frank C. McCord relieved Commander Dresel as commanding officer, the latter becoming the first commanding officer of Akron's sister ship Macon, whose construction was almost complete. Within hours, Akron headed south down the eastern seaboard toward Florida where, after refueling at the Naval Reserve Aviation Base, Opa-locka, Florida, near Miami, the next day proceeded to Guantánamo Bay for an inspection of base sites. At this time the N2Y-1s were used to provide aerial "taxi" service to ferry members of the inspection party back and forth.[6]: 73 

 

Soon thereafter, Akron returned to Lakehurst for local operations which were interrupted by a two-week overhaul and poor weather. In March, it carried out intensive training with an aviation unit of F9C-2s, honing hook-on skills. During the course of these operations, an overfly of Washington DC was made 4 March 1933, the day Franklin D. Roosevelt first took the oath of office as President of the United States.[6]: 74 

 

On 11 March, Akron departed Lakehurst bound for Panama stopping briefly en route at Opa-locka before proceeding on to Balboa where an inspection party looked over a potential air base site. While returning northward, the airship paused at Opa-locka again for local operations exercising gun crews, with the N2Y-1s serving as targets, before getting underway for Lakehurst on 22 March.[6]: 74–75 

Loss

 

Location of crash

 

On the evening of 3 April 1933, Akron cast off from the mooring mast to operate along the coast of New England, assisting in the calibration of radio direction finder stations. Rear Admiral Moffett was again on board along with his aide, Commander Henry Barton Cecil, Commander Fred T. Berry, the commanding officer of NAS Lakehurst, and Lieutenant Colonel Alfred F. Masury, U.S. Army Reserve, a guest of the admiral, the vice-president of Mack Trucks, and a strong proponent of the potential civilian uses of rigid airships.[6]: 77–78 

 

After casting off at 19:28, Akron soon encountered fog and then severe weather, which did not improve when the airship passed over Barnegat Light, New Jersey,[33] at 22:00. According to Richard Smith, "Unknown to the men on board the Akron, they were flying ahead of one of the most violent stormfronts to sweep the North Atlantic States in ten years. It would soon envelop them." Enveloped in fog, increased lightning and heavy rain, it became extremely turbulent at 00:15. The Akron began a rapid nose-down descent, reaching 1100 feet while still falling. Ballast was dumped, which stabilized the ship at 700 feet, and climbed back to 1600 feet cruising altitude. Then a second violent descent sent the Akron downwards at 14 feet per second. "Landing stations" alerted the crew, as the ship descended tail-down. The lower fin struck the sea, water entered the fin, and the stern was dragged under. The engines pulled the ship into a nose-high attitude, then the Akron stalled, and crashed into the sea.[6]: 78–80 

 

Akron broke up rapidly and sank in the stormy Atlantic. The crew of the nearby German merchant ship Phoebus saw lights descending toward the ocean at about 00:23 and altered course to starboard to investigate, with her captain believing that he was witnessing an airplane crash. At 00:55, executive officer Lieutenant Commander Herbert V. Wiley was pulled from the water while the ship's boat picked up three more men: Chief Radioman Robert W. Copeland, Boatswain's Mate Second Class Richard E. Deal, and Aviation Metalsmith Second Class Moody E. Erwin. Despite artificial respiration, Copeland never regained consciousness, and he died aboard Phoebus.[6]: 80  Although the German sailors spotted four or five other men in the water, they did not know their ship had chanced upon the crash of Akron until Lt. Commander Wiley regained consciousness half an hour after being rescued. The crew of Phoebus combed the ocean in boats for over five hours in a fruitless search for more survivors. The Navy blimp J-3—sent out to join the search—also crashed, with the loss of two men.[34]

 

The U.S. Coast Guard cutter Tucker—the first American vessel on the scene—arrived at 06:00, taking the airship's survivors and the body of Copeland on board. Among the other ships combing the area for survivors were the heavy cruiser Portland, the destroyer Cole, the Coast Guard cutter Mojave, and the Coast Guard destroyers McDougal and Hunt, as well as two Coast Guard aircraft. The fishing vessel Grace F from Gloucester, Massachusetts, also assisted in the search, using her seining gear in an effort to recover bodies.[35] Most casualties had been caused by drowning and hypothermia, since the crew had not been issued life jackets, and there had not been time to deploy the single life raft. The accident left 73 dead, and only three survivors. Wiley, standing next to the two other survivors, gave a brief account on 6 April.[36]

Aftermath of loss

See also: Cathedral of the Air

 

Akron's loss spelled the beginning of the end for the rigid airship in the U.S. Navy, especially since one of her leading proponents, Rear Admiral William A. Moffett, was among the dead. President Roosevelt said, "The loss of the Akron with her crew of gallant officers and men is a national disaster. I grieve with the Nation and especially with the wives and families of the men who were lost. Ships can be replaced, but the Nation can ill afford to lose such men as Rear Admiral William A. Moffett and his shipmates who died with him upholding to the end the finest traditions of the United States Navy." The loss of the Akron was the largest loss of life in any airship crash.[37]

 

Macon and other airships received life jackets to avert a repetition of this tragedy. When Macon was damaged in a storm in 1935 and subsequently sank after landing in the sea, 70 of the 72 crew were saved.

 

The songwriter Bob Miller wrote and recorded a song, "The Crash of the Akron", within one day of the disaster.[38]

 

In 2003, the U.S. submarine NR-1 surveyed the wreck site and performed sonar imaging of the Akron's girders.[39]

Assessment

 

For numerous reasons, in the opinion of U.S. naval aviation historian Richard K. Smith,[40] Akron never got the chance to show what it was capable of. Initially, the idea had been to use her as a scout for the fleet, just as the German Navy zeppelins had been used during World War I, with her airplanes being simply useful auxiliaries capable of extending her range of vision or of defending her against attacking enemy aircraft.[41] Gradually, in the minds of the more forward-thinking officers familiar with airship and scouting fleet operations, that was reversed, it and Macon came to be regarded as aircraft carriers, whose sole job was to get the scouting airplanes to the search area and then to support them in their flights.[42][43] The mothership herself should stay in the background, out of sight of enemy surface units, and act merely as a mobile advanced base for the airplanes, which should do all of the actual searching.[44] Any aircraft carrier could do that, but only an airship could do it so quickly since her speed was at least twice that of a surface ship, enabling her to get to the scene or be switched from flank to flank quickly. However, it was an experimental ship, a prototype, and it took time for the doctrine and suitable tactics to evolve. It also took time to develop the techniques of navigating, controlling, and coordinating the scouts. At first, developments were hampered by inadequate radio equipment,[45] as well as the difficulties encountered by the scout pilots in navigating, scouting, and communicating from their cramped open cockpits.[46]

 

Some politicians, some senior officers, and some sections of the press seemed predisposed to judge the airship experiment a failure without regard to the evidence.[47] Even within the Navy's Bureau of Aeronautics, many opposed spending so much on a single asset.[40] Smith also asserts that political pressure inside and outside the navy led to the ship being pushed too early to attempt too much.[48] Little allowance seems to have been made for the fact that this was a prototype, an experimental system, and that tactics for her use were being developed "on the hoof." As a result, the airship's performance in fleet exercises was not all that some had hoped and gave an exaggerated impression of the ship's vulnerability and failed to demonstrate her strengths.[49]

There are many different germs and infections inside and outside of the healthcare setting. Despite the variety of viruses and bacteria, germs spread from person to person through a common series of events. Therefore, to prevent germs from infecting more people, we must break the chain of infection. No matter the germ, there are six points at which the chain can

be broken and a germ can be stopped from infecting another person. The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.

• Infectious agent is the pathogen (germ) that causes diseases

• Reservoir includes places in the environment where the pathogen lives (this includes people,

animals and insects, medical equipment, and soil and water)

• Portal of exit is the way the infectious agent leaves the reservoir (through open wounds, aerosols, and splatter of body fluids including coughing, sneezing, and saliva)

• Mode of transmission is the way the infectious agent can be passed on (through direct or indirect contact, ingestion, or inhalation)

• Portal of entry is the way the infectious agent can enter a new host (through broken skin, the respiratory tract, mucous membranes, and catheters and tubes)

• Susceptible host can be any person (the most vulnerable of whom are receiving healthcare, are immunocompromised, or have invasive medical devices including lines, devices, and airways)

The way to stop germs from spreading is by interrupting this chain at any link. Break the chain by cleaning your hands frequently, staying up to date on your vaccines (including the flu shot), covering coughs and sneezes and staying home when sick, following the rules for standard and contact isolation, using personal protective equipment the right way, cleaning and disinfecting the environment, sterilizing medical instruments and equipment, following safe injection practices, and using antibiotics wisely to prevent antibiotic resistance.

It takes a chain reaction of events for infections to spread to others. The way to stop germs from spreading is by interrupting the chain. When you go into a hospital or other healthcare setting to receive care, you become vulnerable to catching infections. But the good news is that patients, their families, and visitors can take steps to prevent infections by simply knowing the top infection prevention basics!

 

Are you a healthcare professional? Learn how you can break the chain of infection in healthcare settings.

   

The best way to stay healthy while visiting the hospital is to speak up for your care. Don’t be shy. After all, we’re talking about your health. Your doctors, your nurses, and other members of your care team want you to have a voice in your care.

So ask questions, voice concerns, and make sure you’re comfortable with the care you are getting while in the hospital or other healthcare facility.

 

Keeping your hands clean is the number one way to prevent the spread of infection. Clean your hands after using the bathroom; after sneezing, blowing your nose, or coughing; before eating; when visiting someone who is sick; or whenever your hands are dirty.

Make sure that everyone around you, including your healthcare providers and your visitors, do too. Did you see them clean their hands? If not, it’s okay to ask them to clean their hands!

 

Ask about safe injection practices. Safe injection practices are steps that your healthcare providers should follow when they give injections. For example, not using the same needle or syringe on more than one patient.

Remember: One needle, one syringe, only one time.

 

Ask to have your room or equipment cleaned. Keeping healthcare facilities clean is extremely important. It’s very easy for germs to be passed from the surfaces to the hands and to other people.

So speak up and ask to have your room or equipment cleaned if they appear dirty or dusty.

 

Ask questions about the medications that are prescribed to you. Know what they are for, how to take them, how long you should take them, and how often you should take them. If you are taking antibiotics, take them exactly as prescribed, even if you start to feel better.

Using antibiotics the wrong way can cause bacteria to grow into superbugs.

 

Ask about vaccines you need to stay healthy. The majority of Americans who die each year from vaccine-preventable diseases are adults. Vaccines are a very effective way to prevent the suffering (and costs) associated with vaccine-preventable infections.

Vaccines are among the safest medical products available. The potential risks associated with the diseases these vaccines prevent are much greater than the potential risks associated with the vaccines themselves.

 

Know about infection preventionists. These germ sleuths work every day to protect you. Your safety is their #1 priority. They strive to keep you, visitors, volunteers, employees, and healthcare providers safe from infection.

Infection preventionists partner with your healthcare team to make sure everyone is doing the right things to keep you safe from healthcare-associated infections.

 

Become familiar with healthcare-associated infections. Healthcare-associated infections (HAIs) are infections that patients can get while receiving treatment for medical or surgical conditions. No matter where you are—in a hospital, a long-term care facility, outpatient surgery center, dialysis center, doctor’s office, or elsewhere—you are at risk for infections.

These kinds of infections are often preventable.

Evidence always plays a major role in devising a strategy for any global health crisis – it becomes even more important when the circumstances of that crisis continuously evolve. With the total count of Coronavirus patients exceeding 885,000 across more than 170 countries, it is clear that COVID-19 is a once-in-a-lifetime pandemic and a crisis of unprecedented magnitude.Italy and Spain now have over 100,000 confirmed cases of the virus, while the US will soon pass the 200,000 mark. The lesson from these developments is clear: we must abandon the assumptions that COVID-19 will be contained without drastic public health interventions. On 16 March, researchers from Imperial College of London announced a searing report on the impact of an uncontrolled pandemic, that describes the cost of inaction: approximately 510,000 deaths in the UK and 2.2 million in the US. The report highlighted that infections would peak by the middle of June and, without effective policies in place, could lead to as many as 55,000 deaths on the worst day. This scenario is corroborated by emerging evidence suggesting that younger adults, who were previously thought to be less affected – are also prone to developing severe forms of the coronavirus infection. Upon publication of the report, the UK government changed its previous policy of “building herd immunity” and the US reinforced its approach to adopt stricter measures towards containing the spread of the infection.While the numbers in the report are sobering, it does provide guidance on how to develop a global health strategy for containing COVID-19. To be successful, all major countries around the world must act now.

The report described two major approaches available for containing COVID-19. One is mitigation: slowing down the spread of the epidemic but not interrupting the transmission completely, while ensuring the healthcare needs for those who are at risk of developing serious forms of the infection are met. This approach, which includes “social distancing” along with isolation and quarantining of cases, is unlikely to contain the pandemic and may result in the death of thousands of patients while severely burdening health systems, especially available intensive care units. As such, the researchers recommend the second approach, suppression, as more optimal. Suppression refers to a reversal of epidemic spread by reducing the infectivity of the coronavirus and continued maintenance of this approach for up to 18 months. A reversal of spread can be achieved by the implementation of non-pharmaceutical interventions (NPI). These include strict lockdown measures – social distancing in entire populations, the closure of schools and community spaces – and extending these measures until vaccines can be developed. Infectivity of COVID-19 is determined by its reproduction number, or R0 (pronounced R naught), which current epidemiological estimates suggest lies between 1.5 to 3. This means that every COVID-19 patient can infect up to three other people on average. The suppression strategy will require the elimination of human-to-human transmission by lowering the R0 to less than one, which is postulated to halt the spread of the infection. Mitigation strategies, the researchers observe, are unlikely to reduce R0 to less than one. To achieve these metrics, the first step would be to test as many individuals as possible even the ones who may not exhibit symptoms. This is important because coronavirus infection has a longer incubation period of 1-14 days (compared to 1-4 days in flu) and emerging evidence suggests that people with mild or no symptoms may be responsible for the rapid spread of the infection. This approach was also underscored by the Director-General of the World Health Organization), Dr Tedros Ghebreyesus, who highlighted the importance of “breaking the chains of transmission”. This identification of infected individuals by rapid and reliable testing will be crucial to building an effective approach to impede the spread of the infection. The next critical step will be case isolation and voluntary home quarantines. These NPIs should be supplemented by strict social distancing with people maintaining almost six feet of distance along with the closure of schools, universities, bars, and other areas of social gatherings. This is especially important because recent investigation suggests that coronavirus is viable in aerosols for hours and on surfaces for days. The suppression strategy will also ensure that healthcare systems are not overburdened and capacity for critical care is preserved – a practice that has come to be known as “flattening the curve”. Failure to suppress the transmission of infection in countries like Italy has been responsible for the decimation of its healthcare systems leading to thousands of deaths. The implementation of these suppression strategies is also the reason that countries in Asia, such as Singapore, Hong Kong SAR and Taiwan, China, have succeeded in maintaining low case counts of COVID-19. Learning from the experiences of the Severe Acute Respiratory Syndrome (SARS) epidemic of 2003 and swine flu of 2009, these countries instituted strict travel controls and rapid screening and contact tracing of infected individuals. To develop resilient response systems that can halt the transmission, these countries also escalated the production of tests for COVID-19 soon after the genetic sequence of the virus became available. Singapore even enacted mandatory quarantines with criminal penalties for violators. Although some experts have highlighted the limited applicability of complete lockdown measures in developing economies, such countries can still benefit from implementing strict mitigation strategies.With a case fatality rate of up to 3.4% and up to 60% of the global population at risk, many of these measures may seem drastic, but they are also necessary to halt the transmission of this deadly pathogen. It may even seem an overreaction to an epidemic that is not well understood and where comprehensive data is missing. However, given the trajectory of the infection in Italy and the rapid collapse of its entire health system, it is prudent to exercise extreme caution to prevent other countries from trailing that path. In moments of extreme uncertainty, the judgement of leaders is as important as evidence. To combat the pandemic of COVID-19, we will need to sacrifice short-term comforts for long-term gains. More than evidence, this will require courage on the part of national leaders; their next step will become a part of their legacy.

High Dynamic Range (HDR)

 

High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present a similar range of luminance to that experienced through the human visual system. The human eye, through adaptation of the iris and other methods, adjusts constantly to adapt to a broad range of luminance present in the environment. The brain continuously interprets this information so that a viewer can see in a wide range of light conditions.

 

HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different, narrower range, exposures of the same subject matter. Non-HDR cameras take photographs with a limited exposure range, referred to as LDR, resulting in the loss of detail in highlights or shadows.

 

The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR) or standard-dynamic-range (SDR) photographs. HDR images can also be acquired using special image sensors, such as an oversampled binary image sensor.

 

Due to the limitations of printing and display contrast, the extended luminosity range of an HDR image has to be compressed to be made visible. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved local contrast (or exaggerated for artistic effect).

 

In photography, dynamic range is measured in exposure value (EV) differences (known as stops). An increase of one EV, or 'one stop', represents a doubling of the amount of light. Conversely, a decrease of one EV represents a halving of the amount of light. Therefore, revealing detail in the darkest of shadows requires high exposures, while preserving detail in very bright situations requires very low exposures. Most cameras cannot provide this range of exposure values within a single exposure, due to their low dynamic range. High-dynamic-range photographs are generally achieved by capturing multiple standard-exposure images, often using exposure bracketing, and then later merging them into a single HDR image, usually within a photo manipulation program). Digital images are often encoded in a camera's raw image format, because 8-bit JPEG encoding does not offer a wide enough range of values to allow fine transitions (and regarding HDR, later introduces undesirable effects due to lossy compression).

 

Any camera that allows manual exposure control can make images for HDR work, although one equipped with auto exposure bracketing (AEB) is far better suited. Images from film cameras are less suitable as they often must first be digitized, so that they can later be processed using software HDR methods.

 

In most imaging devices, the degree of exposure to light applied to the active element (be it film or CCD) can be altered in one of two ways: by either increasing/decreasing the size of the aperture or by increasing/decreasing the time of each exposure. Exposure variation in an HDR set is only done by altering the exposure time and not the aperture size; this is because altering the aperture size also affects the depth of field and so the resultant multiple images would be quite different, preventing their final combination into a single HDR image.

 

An important limitation for HDR photography is that any movement between successive images will impede or prevent success in combining them afterwards. Also, as one must create several images (often three or five and sometimes more) to obtain the desired luminance range, such a full 'set' of images takes extra time. HDR photographers have developed calculation methods and techniques to partially overcome these problems, but the use of a sturdy tripod is, at least, advised.

 

Some cameras have an auto exposure bracketing (AEB) feature with a far greater dynamic range than others, from the 3 EV of the Canon EOS 40D, to the 18 EV of the Canon EOS-1D Mark II. As the popularity of this imaging method grows, several camera manufactures are now offering built-in HDR features. For example, the Pentax K-7 DSLR has an HDR mode that captures an HDR image and outputs (only) a tone mapped JPEG file. The Canon PowerShot G12, Canon PowerShot S95 and Canon PowerShot S100 offer similar features in a smaller format.. Nikon's approach is called 'Active D-Lighting' which applies exposure compensation and tone mapping to the image as it comes from the sensor, with the accent being on retaing a realistic effect . Some smartphones provide HDR modes, and most mobile platforms have apps that provide HDR picture taking.

 

Camera characteristics such as gamma curves, sensor resolution, noise, photometric calibration and color calibration affect resulting high-dynamic-range images.

 

Color film negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range

 

Tone mapping

Tone mapping reduces the dynamic range, or contrast ratio, of an entire image while retaining localized contrast. Although it is a distinct operation, tone mapping is often applied to HDRI files by the same software package.

 

Several software applications are available on the PC, Mac and Linux platforms for producing HDR files and tone mapped images. Notable titles include

Information stored in high-dynamic-range images typically corresponds to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors as they should appear on a monitor or a paper print. Therefore, HDR image formats are often called scene-referred, in contrast to traditional digital images, which are device-referred or output-referred. Furthermore, traditional images are usually encoded for the human visual system (maximizing the visual information stored in the fixed number of bits), which is usually called gamma encoding or gamma correction. The values stored for HDR images are often gamma compressed (power law) or logarithmically encoded, or floating-point linear values, since fixed-point linear encodings are increasingly inefficient over higher dynamic ranges.

 

HDR images often don't use fixed ranges per color channel—other than traditional images—to represent many more colors over a much wider dynamic range. For that purpose, they don't use integer values to represent the single color channels (e.g., 0-255 in an 8 bit per pixel interval for red, green and blue) but instead use a floating point representation. Common are 16-bit (half precision) or 32-bit floating point numbers to represent HDR pixels. However, when the appropriate transfer function is used, HDR pixels for some applications can be represented with a color depth that has as few as 10–12 bits for luminance and 8 bits for chrominance without introducing any visible quantization artifacts.

 

History of HDR photography

The idea of using several exposures to adequately reproduce a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, as the luminosity range was too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive.

 

Mid 20th century

Manual tone mapping was accomplished by dodging and burning – selectively increasing or decreasing the exposure of regions of the photograph to yield better tonality reproduction. This was effective because the dynamic range of the negative is significantly higher than would be available on the finished positive paper print when that is exposed via the negative in a uniform manner. An excellent example is the photograph Schweitzer at the Lamp by W. Eugene Smith, from his 1954 photo essay A Man of Mercy on Dr. Albert Schweitzer and his humanitarian work in French Equatorial Africa. The image took 5 days to reproduce the tonal range of the scene, which ranges from a bright lamp (relative to the scene) to a dark shadow.

 

Ansel Adams elevated dodging and burning to an art form. Many of his famous prints were manipulated in the darkroom with these two methods. Adams wrote a comprehensive book on producing prints called The Print, which prominently features dodging and burning, in the context of his Zone System.

 

With the advent of color photography, tone mapping in the darkroom was no longer possible due to the specific timing needed during the developing process of color film. Photographers looked to film manufacturers to design new film stocks with improved response, or continued to shoot in black and white to use tone mapping methods.

 

Color film capable of directly recording high-dynamic-range images was developed by Charles Wyckoff and EG&G "in the course of a contract with the Department of the Air Force". This XR film had three emulsion layers, an upper layer having an ASA speed rating of 400, a middle layer with an intermediate rating, and a lower layer with an ASA rating of 0.004. The film was processed in a manner similar to color films, and each layer produced a different color. The dynamic range of this extended range film has been estimated as 1:108. It has been used to photograph nuclear explosions, for astronomical photography, for spectrographic research, and for medical imaging. Wyckoff's detailed pictures of nuclear explosions appeared on the cover of Life magazine in the mid-1950s.

 

Late 20th century

Georges Cornuéjols and licensees of his patents (Brdi, Hymatom) introduced the principle of HDR video image, in 1986, by interposing a matricial LCD screen in front of the camera's image sensor, increasing the sensors dynamic by five stops. The concept of neighborhood tone mapping was applied to video cameras by a group from the Technion in Israel led by Dr. Oliver Hilsenrath and Prof. Y.Y.Zeevi who filed for a patent on this concept in 1988.

 

In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera that combined two images captured by a sensor3435 or simultaneously3637 by two sensors of the camera. This process is known as bracketing used for a video stream.

 

In 1991, the first commercial video camera was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Georges Cornuéjols.

 

Also in 1991, Georges Cornuéjols introduced the HDR+ image principle by non-linear accumulation of images to increase the sensitivity of the camera: for low-light environments, several successive images are accumulated, thus increasing the signal to noise ratio.

 

In 1993, another commercial medical camera producing an HDR video image, by the Technion.

 

Modern HDR imaging uses a completely different approach, based on making a high-dynamic-range luminance or light map using only global image operations (across the entire image), and then tone mapping the result. Global HDR was first introduced in 19931 resulting in a mathematical theory of differently exposed pictures of the same subject matter that was published in 1995 by Steve Mann and Rosalind Picard.

 

On October 28, 1998, Ben Sarao created one of the first nighttime HDR+G (High Dynamic Range + Graphic image)of STS-95 on the launch pad at NASA's Kennedy Space Center. It consisted of four film images of the shuttle at night that were digitally composited with additional digital graphic elements. The image was first exhibited at NASA Headquarters Great Hall, Washington DC in 1999 and then published in Hasselblad Forum, Issue 3 1993, Volume 35 ISSN 0282-5449.

 

The advent of consumer digital cameras produced a new demand for HDR imaging to improve the light response of digital camera sensors, which had a much smaller dynamic range than film. Steve Mann developed and patented the global-HDR method for producing digital images having extended dynamic range at the MIT Media Laboratory. Mann's method involved a two-step procedure: (1) generate one floating point image array by global-only image operations (operations that affect all pixels identically, without regard to their local neighborhoods); and then (2) convert this image array, using local neighborhood processing (tone-remapping, etc.), into an HDR image. The image array generated by the first step of Mann's process is called a lightspace image, lightspace picture, or radiance map. Another benefit of global-HDR imaging is that it provides access to the intermediate light or radiance map, which has been used for computer vision, and other image processing operations.

 

21st century

In 2005, Adobe Systems introduced several new features in Photoshop CS2 including Merge to HDR, 32 bit floating point image support, and HDR tone mapping.

 

On June 30, 2016, Microsoft added support for the digital compositing of HDR images to Windows 10 using the Universal Windows Platform.

 

HDR sensors

Modern CMOS image sensors can often capture a high dynamic range from a single exposure. The wide dynamic range of the captured image is non-linearly compressed into a smaller dynamic range electronic representation. However, with proper processing, the information from a single exposure can be used to create an HDR image.

 

Such HDR imaging is used in extreme dynamic range applications like welding or automotive work. Some other cameras designed for use in security applications can automatically provide two or more images for each frame, with changing exposure. For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. Some of the sensor may even combine the two images on-chip so that a wider dynamic range without in-pixel compression is directly available to the user for display or processing.

Infrared Photography

 

In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.)

 

When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance known as the "Wood Effect," an effect mainly caused by foliage (such as tree leaves and grass) strongly reflecting in the same way visible light is reflected from snow. There is a small contribution from chlorophyll fluorescence, but this is marginal and is not the real cause of the brightness seen in infrared photographs. The effect is named after the infrared photography pioneer Robert W. Wood, and not after the material wood, which does not strongly reflect infrared.

 

The other attributes of infrared photographs include very dark skies and penetration of atmospheric haze, caused by reduced Rayleigh scattering and Mie scattering, respectively, compared to visible light. The dark skies, in turn, result in less infrared light in shadows and dark reflections of those skies from water, and clouds will stand out strongly. These wavelengths also penetrate a few millimeters into skin and give a milky look to portraits, although eyes often look black.

 

Until the early 20th century, infrared photography was not possible because silver halide emulsions are not sensitive to longer wavelengths than that of blue light (and to a lesser extent, green light) without the addition of a dye to act as a color sensitizer. The first infrared photographs (as distinct from spectrographs) to be published appeared in the February 1910 edition of The Century Magazine and in the October 1910 edition of the Royal Photographic Society Journal to illustrate papers by Robert W. Wood, who discovered the unusual effects that now bear his name. The RPS co-ordinated events to celebrate the centenary of this event in 2010. Wood's photographs were taken on experimental film that required very long exposures; thus, most of his work focused on landscapes. A further set of infrared landscapes taken by Wood in Italy in 1911 used plates provided for him by CEK Mees at Wratten & Wainwright. Mees also took a few infrared photographs in Portugal in 1910, which are now in the Kodak archives.

 

Infrared-sensitive photographic plates were developed in the United States during World War I for spectroscopic analysis, and infrared sensitizing dyes were investigated for improved haze penetration in aerial photography. After 1930, new emulsions from Kodak and other manufacturers became useful to infrared astronomy.

 

Infrared photography became popular with photography enthusiasts in the 1930s when suitable film was introduced commercially. The Times regularly published landscape and aerial photographs taken by their staff photographers using Ilford infrared film. By 1937 33 kinds of infrared film were available from five manufacturers including Agfa, Kodak and Ilford. Infrared movie film was also available and was used to create day-for-night effects in motion pictures, a notable example being the pseudo-night aerial sequences in the James Cagney/Bette Davis movie The Bride Came COD.

 

False-color infrared photography became widely practiced with the introduction of Kodak Ektachrome Infrared Aero Film and Ektachrome Infrared EIR. The first version of this, known as Kodacolor Aero-Reversal-Film, was developed by Clark and others at the Kodak for camouflage detection in the 1940s. The film became more widely available in 35mm form in the 1960s but KODAK AEROCHROME III Infrared Film 1443 has been discontinued.

 

Infrared photography became popular with a number of 1960s recording artists, because of the unusual results; Jimi Hendrix, Donovan, Frank and a slow shutter speed without focus compensation, however wider apertures like f/2.0 can produce sharp photos only if the lens is meticulously refocused to the infrared index mark, and only if this index mark is the correct one for the filter and film in use. However, it should be noted that diffraction effects inside a camera are greater at infrared wavelengths so that stopping down the lens too far may actually reduce sharpness.

 

Most apochromatic ('APO') lenses do not have an Infrared index mark and do not need to be refocused for the infrared spectrum because they are already optically corrected into the near-infrared spectrum. Catadioptric lenses do not often require this adjustment because their mirror containing elements do not suffer from chromatic aberration and so the overall aberration is comparably less. Catadioptric lenses do, of course, still contain lenses, and these lenses do still have a dispersive property.

 

Infrared black-and-white films require special development times but development is usually achieved with standard black-and-white film developers and chemicals (like D-76). Kodak HIE film has a polyester film base that is very stable but extremely easy to scratch, therefore special care must be used in the handling of Kodak HIE throughout the development and printing/scanning process to avoid damage to the film. The Kodak HIE film was sensitive to 900 nm.

 

As of November 2, 2007, "KODAK is preannouncing the discontinuance" of HIE Infrared 35 mm film stating the reasons that, "Demand for these products has been declining significantly in recent years, and it is no longer practical to continue to manufacture given the low volume, the age of the product formulations and the complexity of the processes involved." At the time of this notice, HIE Infrared 135-36 was available at a street price of around $12.00 a roll at US mail order outlets.

 

Arguably the greatest obstacle to infrared film photography has been the increasing difficulty of obtaining infrared-sensitive film. However, despite the discontinuance of HIE, other newer infrared sensitive emulsions from EFKE, ROLLEI, and ILFORD are still available, but these formulations have differing sensitivity and specifications from the venerable KODAK HIE that has been around for at least two decades. Some of these infrared films are available in 120 and larger formats as well as 35 mm, which adds flexibility to their application. With the discontinuance of Kodak HIE, Efke's IR820 film has become the only IR film on the marketneeds update with good sensitivity beyond 750 nm, the Rollei film does extend beyond 750 nm but IR sensitivity falls off very rapidly.

  

Color infrared transparency films have three sensitized layers that, because of the way the dyes are coupled to these layers, reproduce infrared as red, red as green, and green as blue. All three layers are sensitive to blue so the film must be used with a yellow filter, since this will block blue light but allow the remaining colors to reach the film. The health of foliage can be determined from the relative strengths of green and infrared light reflected; this shows in color infrared as a shift from red (healthy) towards magenta (unhealthy). Early color infrared films were developed in the older E-4 process, but Kodak later manufactured a color transparency film that could be developed in standard E-6 chemistry, although more accurate results were obtained by developing using the AR-5 process. In general, color infrared does not need to be refocused to the infrared index mark on the lens.

 

In 2007 Kodak announced that production of the 35 mm version of their color infrared film (Ektachrome Professional Infrared/EIR) would cease as there was insufficient demand. Since 2011, all formats of color infrared film have been discontinued. Specifically, Aerochrome 1443 and SO-734.

 

There is no currently available digital camera that will produce the same results as Kodak color infrared film although the equivalent images can be produced by taking two exposures, one infrared and the other full-color, and combining in post-production. The color images produced by digital still cameras using infrared-pass filters are not equivalent to those produced on color infrared film. The colors result from varying amounts of infrared passing through the color filters on the photo sites, further amended by the Bayer filtering. While this makes such images unsuitable for the kind of applications for which the film was used, such as remote sensing of plant health, the resulting color tonality has proved popular artistically.

 

Color digital infrared, as part of full spectrum photography is gaining popularity. The ease of creating a softly colored photo with infrared characteristics has found interest among hobbyists and professionals.

 

In 2008, Los Angeles photographer, Dean Bennici started cutting and hand rolling Aerochrome color Infrared film. All Aerochrome medium and large format which exists today came directly from his lab. The trend in infrared photography continues to gain momentum with the success of photographer Richard Mosse and multiple users all around the world.

 

Digital camera sensors are inherently sensitive to infrared light, which would interfere with the normal photography by confusing the autofocus calculations or softening the image (because infrared light is focused differently from visible light), or oversaturating the red channel. Also, some clothing is transparent in the infrared, leading to unintended (at least to the manufacturer) uses of video cameras. Thus, to improve image quality and protect privacy, many digital cameras employ infrared blockers. Depending on the subject matter, infrared photography may not be practical with these cameras because the exposure times become overly long, often in the range of 30 seconds, creating noise and motion blur in the final image. However, for some subject matter the long exposure does not matter or the motion blur effects actually add to the image. Some lenses will also show a 'hot spot' in the centre of the image as their coatings are optimised for visible light and not for IR.

 

An alternative method of DSLR infrared photography is to remove the infrared blocker in front of the sensor and replace it with a filter that removes visible light. This filter is behind the mirror, so the camera can be used normally - handheld, normal shutter speeds, normal composition through the viewfinder, and focus, all work like a normal camera. Metering works but is not always accurate because of the difference between visible and infrared refraction. When the IR blocker is removed, many lenses which did display a hotspot cease to do so, and become perfectly usable for infrared photography. Additionally, because the red, green and blue micro-filters remain and have transmissions not only in their respective color but also in the infrared, enhanced infrared color may be recorded.

 

Since the Bayer filters in most digital cameras absorb a significant fraction of the infrared light, these cameras are sometimes not very sensitive as infrared cameras and can sometimes produce false colors in the images. An alternative approach is to use a Foveon X3 sensor, which does not have absorptive filters on it; the Sigma SD10 DSLR has a removable IR blocking filter and dust protector, which can be simply omitted or replaced by a deep red or complete visible light blocking filter. The Sigma SD14 has an IR/UV blocking filter that can be removed/installed without tools. The result is a very sensitive digital IR camera.

 

While it is common to use a filter that blocks almost all visible light, the wavelength sensitivity of a digital camera without internal infrared blocking is such that a variety of artistic results can be obtained with more conventional filtration. For example, a very dark neutral density filter can be used (such as the Hoya ND400) which passes a very small amount of visible light compared to the near-infrared it allows through. Wider filtration permits an SLR viewfinder to be used and also passes more varied color information to the sensor without necessarily reducing the Wood effect. Wider filtration is however likely to reduce other infrared artefacts such as haze penetration and darkened skies. This technique mirrors the methods used by infrared film photographers where black-and-white infrared film was often used with a deep red filter rather than a visually opaque one.

 

Another common technique with near-infrared filters is to swap blue and red channels in software (e.g. photoshop) which retains much of the characteristic 'white foliage' while rendering skies a glorious blue.

 

Several Sony cameras had the so-called Night Shot facility, which physically moves the blocking filter away from the light path, which makes the cameras very sensitive to infrared light. Soon after its development, this facility was 'restricted' by Sony to make it difficult for people to take photos that saw through clothing. To do this the iris is opened fully and exposure duration is limited to long times of more than 1/30 second or so. It is possible to shoot infrared but neutral density filters must be used to reduce the camera's sensitivity and the long exposure times mean that care must be taken to avoid camera-shake artifacts.

 

Fuji have produced digital cameras for use in forensic criminology and medicine which have no infrared blocking filter. The first camera, designated the S3 PRO UVIR, also had extended ultraviolet sensitivity (digital sensors are usually less sensitive to UV than to IR). Optimum UV sensitivity requires special lenses, but ordinary lenses usually work well for IR. In 2007, FujiFilm introduced a new version of this camera, based on the Nikon D200/ FujiFilm S5 called the IS Pro, also able to take Nikon lenses. Fuji had earlier introduced a non-SLR infrared camera, the IS-1, a modified version of the FujiFilm FinePix S9100. Unlike the S3 PRO UVIR, the IS-1 does not offer UV sensitivity. FujiFilm restricts the sale of these cameras to professional users with their EULA specifically prohibiting "unethical photographic conduct".

 

Phase One digital camera backs can be ordered in an infrared modified form.

 

Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared (see Infrared spectrum#Commonly used sub-division scheme). They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to longer infrared wavelengths including those used in infrared astronomy often require cooling to reduce thermally induced dark currents in the sensor (see Dark current (physics)). Lower cost uncooled thermographic digital cameras operate in the Long Wave infrared band (see Thermographic camera#Uncooled infrared detectors). These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well.

Scene: Madison Square Garden 2

A low murmur swept down the avenue in front of the Garden as a black lead sedan and a fleet of white motorcycle escorts slowly rolled in. Four armored limousines followed, flanked by NYPD and state police SUVs. Behind them trailed a line of communication trucks, ambulances, and news vans—no more than fifty vehicles in all, but the weight of their presence was overwhelming.

The motorcade moved as if traffic signals held no meaning. The street had been completely shut down, and the convoy advanced in perfect synchrony. Police radio chatter leaked from the vehicles, while the blocked-off sidewalks were crowded with reporters clutching cameras and riot police standing firm. Near the center, three jet-black SUVs carried CAT operatives, their eyes scanning the street like silent sentinels from behind suppressor-equipped rifles.

On top of the limousines, state-of-the-art jamming devices disrupted all outside signals. Trailing them was a “Roadrunner” communications command vehicle bristling with antennas, maintaining real-time encrypted communication with the command center beneath the Garden.

At the tail end were fire department rapid response units, a hazmat vehicle, and two ambulances. The arrival of a presidential candidate was no longer a mere movement—it was a military operation. The city responded like a living neural network, absorbing and adjusting to the convoy’s every move.

Onlookers lined the barricades—civilians raising smartphones overhead, and journalists with grim faces behind their lenses. No one spoke. The crowd stood in solemn silence, bathed in the red and blue pulses of rotating lights, watching as the procession swept past like a scene from a film. But this wasn’t a movie. The silence was real. No one dared crack a joke.

Sniper teams were stationed on rooftops around the Garden. Occasionally, the word “clear” crackled over the comms. Inside the building, only those who had passed facial recognition were permitted to take position. In the chilled surveillance room where Jack sat, hundreds of camera feeds rotated every few seconds across the screens.

Inside the presumed presidential limousine, darkness cloaked everything—no figures visible behind the glass. Yet everyone on-site knew those clear windows hid layers of invisible defense. That silence, designed to preserve life, carried with it a deadly order that blanketed the entire convoy.

Overhead, two Black Hawk helicopters glided in low and began to hover above the Garden. They were escape vessels, should the worst occur—but more than that, they were a reminder that this place was, for tonight, a battlefield.

In the command room on the Garden’s B3 level, Jack sat under the blue glow of the monitors, listening intently to the radio in his ear.

“Eagle has arrived. Parking complete on B3. Zebra point passed. T-minus 45 seconds to approach.”

The voice in his earpiece made him bite his lip unconsciously. The coffee in his cup had long gone cold.

Onscreen, the divided camera feeds displayed the barricades on Seventh Avenue, snipers in standby, and now—the black limousine sliding into the underground garage.

The air tightened. Time became tangible. The tick of the second hand grew louder in everyone’s ears. Jack’s fingers trembled slightly as they reached for the radio button.

 

Scene: Madison Square Garden 1

Jack shifted the donut box in his hand and pressed the button for B3. The air in the elevator was cold, and he wiped the sweat from his brow as he watched the lights descend. The contrast with the heat above made his vision blur slightly.

Stepping out, he turned right. Immediately on the left was the briefing room door, where a security man in a rumpled suit greeted him.

“Everyone’s already waiting.”

Jack stood before the sensor and calmly turned his face toward it. A few seconds later, a mechanical chime signaled access approval, and the heavy fireproof doors slid open.

Once inside, Jack offered a small smile.

“I brought donuts. Make sure everyone gets some later.”

The security man grinned behind his sunglasses.

Beyond the thick soundproof door, 32 monitors glowed blue in the dim room. Staff members moved briskly and silently between the machines. The hum of servers filled the space, punctuated only by the occasional alert. In the center was the commander’s seat, surrounded in a ring by workstations. The wall-sized screen displayed rapid live cuts from over 400 arena cameras—spectator stands, lobby, corridors, VIP lounge, loading dock, backstage, utility room, underground passages…

If a single rat appeared in those tunnels, they’d be able to track it straight to the sewers.

Jack sat in the commander’s chair and flipped the switch on the gooseneck mic in front of him. Its flexible neck trembled as the red indicator light came on.

“I’ve got donuts. Sorry, no glazed. There’s Boston Cream, Chocolate Frosted, Strawberry Frosted, and Old-Fashioned. No coffee, so grab your own.”

“Old-Fashioned for me,” came Ben’s voice from the loading dock. He adjusted the transparent tube of his earpiece and muttered into his collar.

Jack gave a faint smile, then grew serious again as he leaned toward the mic.

“Eagle is about to arrive. Entering through Ben’s loading dock. Three minutes to VIP room. Fifteen-minute briefing. Then onstage. Let me remind you—tonight marks the official nomination of the presidential candidate at the National Convention. First Republican convention held here in over twenty years. Also, his fiancée, Eleanor Blake, is with him. Stunning and brilliant. Try not to fall for her. The only ones you’re allowed to admire are bulky bruisers in tactical gear. And don’t forget, VP candidate Cole Harrison is here too—he’s the leash on our foul-mouthed Justin. No matter what he says, don’t punch back. I’ll be the one getting punched later.”

Jack checked his watch.

“One minute out. When Justin’s team heads home, dig into the donuts. Over and out.”

From the monitor showing the VIP lounge, Daryl spoke up behind him.

“Jack, better check in with Elijah at the hospital. Make sure he’s on standby.”

Without turning, Jack raised his hand and called out.

“Elijah, you copy? Daryl thinks you’re chilling at Starbucks.”

Laughter came through the speaker, followed by the chaotic background noise of Bellevue Hospital.

“Daryl, how’d you know? I was just thinking of getting Jack fired.”

Swiveling in his chair, Daryl laughed back at the screen.

“Let’s hope Justin doesn’t end up in your ER.”

Jack cut in.

“All stations, go. Justin’s here. Stick to the plan. Let’s move.”

———————————

Scene: Madison Square Garden 3 — Justin, Eleanor, Cole

The door of the limousine opened from within, and Justin Bradford stepped out with a short sigh.

“Damn. It’s suffocating down here. Even a stray dog would turn up its nose at this parking garage.”

He brushed off the hem of his suit jacket with one hand, casting a grimace toward the concrete gloom.

Vice presidential candidate Cole Harrison followed quietly behind. Eight years older than Justin, Cole had once stood by Justin’s father, Lysus Bradford—through every rally and protest, until the day Lysus, still registered as a Democrat, was gunned down by a sniper. Cole had admired Lysus deeply for his commitment to voicing the will of the unheard.

Justin yawned, wide and unfiltered. Cole spoke gently beside him.

“This was the safest option. Too many unknowns outside. It’s dangerous.”

“Cole, you’re the biggest unknown we’ve got.”

“And that makes two of us, Justin,” Cole replied with a small, knowing smile.

The click of white heels echoed faintly as Eleanor Blake stepped onto the stained concrete. She wore a pale beige coat over her dress and moved with quiet elegance. Though her brow creased slightly at the stagnant air, she quickly replaced it with a smile and walked toward Justin.

“Justin,” she said, her voice gentle yet firm, “no more jokes at the staff’s expense. These people would lay down their lives for you.”

Justin gave a small, lopsided smile and brushed a kiss against her cheek.

“For their sake, I better live up to it.”

Flanked by security, the three of them began walking down the dim corridor. Faint LED lights flickered overhead. Dirty walls, cold silence, and a chill that crept under their skin accompanied them.

“These hallways always get to me,” Justin muttered.

“I understand,” Eleanor said softly. “But this is the safest route.”

“That’s exactly why we should be grateful,” Cole added. “It’s this kind of space that protects us.”

Eventually, they reached the elevator reserved for dignitaries. The face recognition system chirped quietly as it confirmed their identities.

“Just a few more steps to the VIP lounge,” said one of the agents.

Justin glanced back at Eleanor and shrugged.

“Let’s shake the Garden tonight.”

She touched his arm lightly and smiled.

“I’m counting on you, Justin.”

The three of them stepped into the elevator, the doors closing quietly behind them as it carried them upward.

 

Scene: Totto Ramen — Ana, Mika, Motorcade

— Red, Yellow, Blue —

It was just after 7 p.m. when a light rain began to fall on East 52nd Street.

Ana leaned against the wall of an old building next to Totto Ramen, absently watching the changing traffic light at the intersection to her right. The air was heavy with humid heat clinging to the concrete, making even the pedestrians seem to move slower than usual.

The signal turned green. As she dabbed her forehead with a handkerchief and squinted into the distance, she spotted Kana on the far side of the crosswalk, waving and running toward her with a smile.

Then, suddenly, the air shifted.

From the far side of the intersection, a fleet of black SUVs glided in, soundless and ghostlike. In the few dozen seconds between the lead vehicle’s arrival and the armored limousine at the rear disappearing, the entire intersection was sealed off—no one passed.

As the convoy disappeared down the avenue, the signal changed again. Foot traffic resumed. The city inhaled.

Kana reemerged from the crowd and waved once more.

After wrapping up their exhibit, Ana and Mika had packed their gear into Mika’s car and headed into Manhattan. Ana’s husband, Arjun, worked at LuminaTech Innovations—a hybrid company based in Williamsburg specializing in AI, cloud services, and cybersecurity. Though it was his day off, he’d had a meeting in Hudson Yards and was on a separate schedule from Ana.

Totto Ramen was nearby, and ever since Mika had first brought her there, it had become a favorite for Ana and Arjun alike.

“Sorry to keep you waiting. It’s been such a lovely day,” Mika said, slightly out of breath.

By “lovely,” she meant the two sharply dressed men from that morning, still lingering in their thoughts.

Ana answered with mild disinterest.

“Was it? That your type, Mika?”

Mika shrugged and smiled.

“Mm, I like someone close enough that I can run home to my parents if I need to.”

They laughed as they slid open the ramen shop’s wooden door and took seats at the counter. The place was bustling with Asian families enjoying their weekend. Familiar Japanese drifted from the far end of the counter.

Ana’s iPhone buzzed. It was a video call from Arjun.

She tapped the screen. His apologetic face appeared.

“The meeting’s running long. Go ahead and eat without me.”

Ana smiled gently.

“Be careful. A whole swarm of black cars just swept through here.”

Arjun responded immediately.

“They’re probably heading to the Garden. There’s supposed to be a Republican convention tonight. The candidate’s making his appearance.”

Mika, having caught the gist, nodded deeply.

“Yeah, it’s felt weird all day. The city’s tense—not your usual weekend.”

—————————————

Scene: Red Hook 1 — Amir and Rafi

Red Hook stood apart, even within Brooklyn.

Shielded by the shadows of skyscrapers, the red-brick warehouses, worn by wind and rain, groaned softly in the breeze. Each gust from the sea layered fresh salt onto the air, leaving streaks of rust blooming along the warehouse doors.

Beyond a broken fence, a long-unused warehouse door creaked open.

Amir stepped inside, allowing his eyes to adjust to the darkness. The smell of oil soaked into the concrete filled his nostrils.

“Let’s start here,” he said.

Rafi nodded without a word.

They had first come to this place five winters ago.

Having lost everything in Gaza at the hands of Israel, the two had fled legally through Egypt and Turkey, eventually arriving in Tapachula in southern Mexico. There, they made contact with a smuggler known as a coyote.

Rafi paid $12,000 per person to the traffickers—using cryptocurrency hacked through North Korean channels. The coins had been stolen through a North Korea–linked hacking syndicate. Amir wrote the code himself and erased all trace of the transaction. They had crossed borders not with blood, but with digits.

Later, under cover of night, they slipped beneath a border fence and entered the United States by land.

The night sky over Texas was a shade of dark blue they had never seen before. Low and clear, the deep blue held a fleeting kind of hope. But that hope was far outweighed by the hatred that had taken root in their hearts.

場面　マディソンスクエアガーデン２

 

　ガーデン正面の通りがわずかにざわめき、先導の黒いセダンと白バイク隊がゆっくりと進入してきた。次いで装甲に覆われたリムジンが４台つづき、市警と州警のSUVがその脇を固め、後方には通信車両、救急車、そして報道バンの列……　全部でざっと５０台にも満たないが、その重厚感は圧倒的だった――。

　車列は信号すら意味をなさず、完全に遮断された通りを、隊列の呼吸に従って前進していく。警察無線の交信が車外に漏れ、通行止めの歩道にはカメラを構えた記者と機動隊員が混じり合っていた。中腹には「CAT」と呼ばれる武装部隊が乗る漆黒のSUVが３台並び、サプレッサー付きライフルを持った隊員が、まるで車内から通りをスキャンするように視線を動かしている。

　リムジンの天井には、最新の妨害電波装置が搭載され、外部通信を一時的に遮断する。さらにその後方を、アンテナが林立した“ロードランナー”と呼ばれる通信司令車が追走し、ガーデン地下の指揮室とリアルタイムで暗号通信を続けている。

　車列の最後尾には消防局の緊急対応車、化学物質対応車、そして２台の救急車が控えていた。大統領候補がこの都市に足を踏み入れるというのは、もはや“移動”ではなく、“軍事行動”のようだった。街全体が、ひとつの生きた神経網のように、その動線を受け止めていた。

　歩道の柵沿いには、スマートフォンを高く掲げる市民と、顔を強張らせた報道カメラマンたちが入り混じっていた。群衆は押し黙り、ただエンジンのうなりと回転灯の光に照らされながら、目の前を通り過ぎる車列を見守っていた。まるで映画のワンシーンのようだが、空気は静まり返り、誰一人として軽口を叩く者はいない。

　ガーデン周辺の屋上には狙撃班が配備され、時折、無線越しに「クリア」の声が交錯した。建物内の全階層には顔認証を通過した要員だけが配置され、冷房の効いたジャックのいる監視室では、数百台のカメラ映像が数秒ごとに切り替わっている。

　大統領候補が乗ると目されるリムジンの車内は暗く、ガラス越しに人影すら映らない。だが、その曇りのない窓には、目に見えない幾重もの防御層が仕込まれていることを、現場の誰もが理解していた。命を守るために設計された沈黙と、殺気を孕んだ秩序が、車列全体を覆っている。

　背後から、２機のブラックホークが上空をなめるように飛来し、ガーデンの屋上でホバリングを始めた。万が一の脱出手段であり、また、この場が“戦場”であることを暗に示す存在だった。

　ジャックは、ガーデン地下三階の指令室で、モニターの青白い光に顔を照らされながら、無線に耳を傾けていた。

「イーグル、地下駐車場レベルB3にて停車完了。ポイント・ゼブラ通過。接近までTマイナス45秒」

　耳元のイヤーピースから流れるその声に、彼は無意識に唇を噛んだ。手元のカップに入ったコーヒーは、すでにぬるくなっていた。

　モニターには分割されたカメラ映像がずらりと並んでいる。第七通りのバリケード、スタンバイ中の狙撃手、そして今、地下駐車場の入口に黒いリムジンが滑り込む様子が映し出されていた。

　空気が一気に張り詰めた。誰もが秒針の音を意識し始め、静寂の中に微かな緊張が走った。ジャックの指が、わずかに震えながらも無線の送信ボタンに触れた。

  

場面　マディソンスクエアガーデン１

 

　エレベーターに乗ったジャックは、手にしたドーナツの箱を持ち替えると、地下三階へのボタンを押した。冷房の効いたエレベーター内で下っていくランプを見上げたまま、額の汗を拭った。熱した地上からの温度差で多少視界が滲んでいた。

　降りて、右手に行くと、すぐ左側にブリーフィングルームの扉があり、よれたスーツを着たセキュリティーの男性がジャックに挨拶した。

「みなさん、もうお待ちですよ」

　ジャックはセンサーの前に立ち、静かに顔を向けた。数秒後、「アクセス承認」の電子音とともに、重たい防火扉が左右に開いた。

　クリアするとジャックは、口元を緩めていった。

「ドーナツ買ってきたよ。あとでみんなで食べてくれ」

　セキュリティーの男性は、白い歯を見せ、サングラス越しに微笑んだ。

　厚い防音扉を越えると、薄暗い空間に32面のモニターが青白く光っていた。スタッフが機器の合間を縫って、言葉少なに忙しなく行き交っていく。室内には低く唸るサーバーの音と、時折アラート音だけが響いている。部屋の中央には指揮官席、その周囲に円を描くように並んだワークステーション。壁面いっぱいの巨大スクリーンには、アリーナ内400台以上のカメラがライブ映像を忙しなく切り替え、流し続けている。客席、ロビー、通路、VIPラウンジ、搬入口、ステージ裏、電気設備室、地下通路….

　もしも地下通路にねずみが一匹現れたら、下水溝まで追跡できるはずだ。

　ジャックは指揮官席に腰を下ろし、前方に据え付けられたグースネックマイクのスイッチを押した。しなる首元がわずかに揺れ、赤いインジケーターが点灯した。

「みんな、ドーナツを買ってきた。残念ながらグレーズドは売り切れだった。ボストンクリーム、チョコフロステッド、ストロベリーフロステッド、オールドファッション、以上だ。コーヒーもないからな。勝手に飲むように」

「ジャック、俺はオールドファッションな」

　搬入口にいるベンが、耳に伸びたセキュリティイヤピースの透明なチューブを整えながら、襟元に指を添え、モニター越しに呟いた。

　ジャックは軽く微笑み返してから、声を整え、目の前のマイクに向かって、真剣に伝えた。

「まもなく、イーグルがやってくる。ベンのいる搬入口から入り、３分でVIPルームへ。１５分の打ち合わせ後、アリーナへ登壇する。もう一度確認するが、今夜は大統領候補の指名が正式に確定する全国党大会だ。共和党は、２０年以上振りにここで開催するらしい。それから、フィアンセのエリノア・ブレイクもいっしょだ。容姿端麗な才女だ。見惚れるなよ。お前らが見惚れていいのは筋肉隆々の荒くれものだけだ。さらに副大統領候補のコール・ハリソンもいっしょだ。口の悪いジャスティンのお目付役だ。何を言われても決して殴り返すな。俺があとで殴られるからな」

　ジャックは腕時計を見た。

「あと１分で到着だ。ジャスティン一行が帰宅したら、ドーナツをたらふく食べてくれ。以上だ」

　画面左側に映ったVIPラウンジに見入っていたダリルが、ジャックの背中にいった。

「ジャック、病院のイライジャにも確認したほうがいい。ちゃんと待機しているようにってね」

　ジャックは背を向けたまま、腕を上げて返答するとイライジャに問いかけた。

「聞こえるか、イライジャ。お前がスタバでくつろいでると疑われてるぞ、ダリルに」

　イライジャは、笑いながら即答した。背後に、ベルビュー病院内の忙しないアナウンスが走っている。のんびりしたイライジャの声とは正反対だ。

「ダリル、なんでばれた？　そろそろジャックの首を飛ばそうと思ってさ」

　椅子を回転させたダリルは、右手のモニターに目を落としながら、イライジャに笑いながらいった。

「お前のところに、ジャスティンが運ばれないことを祈るよ」

　ジャックは、二人の会話を遮った。

「全員、スタートだ。ジャスティンが到着した。打ち合わせどおりに。頼んだぞ」

  

場面　マディソンスクエアガーデン３　ジャスティン、エリノア、コール

 

　リムジンのドアが内側から開き、ジャスティン・ブラッドフォードは短くため息をついて足を踏み出した。

「まったく、息が詰まるな。地下駐車場なんて、野良犬でも嫌がる」

　スーツの裾を片手で乱暴に払いつつ、顔をしかめて辺りを見回した。その後ろから、副大統領候補のコール・ハリソンが静かに車を降りた。彼はジャスティンより8歳年上だったが、かつてはその父、ライサス・ブラッドフォードのもとで行動を共にし、彼が民主党に籍を置き、狙撃により命を落とすその時まで、傍らで支え続けていた。ライサスが声なき国民の想いを代弁しようとする姿に、コールは深い感銘を受けていた。

　大きなあくびをこぼしたジャスティンに、コールは穏やかに言った。

「セキュリティ上の最善策だ。外は、あまりにも不確定要素が多い。危険だ」

「コールの言動の方がよほど先が読めないけどね」

「ジャスティン、そのままお前に返すよ」

　ジャスティンの皮肉に、コールは軽く微笑みながら冷静に返した。

　エリノア・ブレイクの白いハイヒールが、駐車場の暗いコンクリートに静かに降りた。淡いベージュのコートを羽織った彼女は、ヒールの音も控えめに、優雅に車外へ降り立った。地下の濁った空気に微かに眉を寄せながらも、すぐに笑みを浮かべ直し、ジャスティンに歩み寄った。

「ジャスティン、スタッフにつまらない冗談はやめてね。みんな、あなたのために命を投げ出す人たちよ」

　彼女の声は柔らかいが、芯のあるものだった。

　ジャスティンは少し顔をほころばせ、エリノアの頬に軽いキスをした。

「命か…なら、俺もその期待に応えないとな」

　セキュリティーに囲われた三人は地下駐車場の薄暗い通路へと歩みを進めた。所々薄汚れた壁と天井のLEDライトが冷たく落ちている。冷たさと静寂が辺りを覆っている。

「この手の通路は、いつ見ても気が滅入るな」

　ジャスティンが呟いた。

「気持ちはわかるけど、ここが最も安全なルートよ」エリノアが柔らかく返す。コールが間を埋めるように言った。

「こうした環境だからこそ、私たちが守られている。感謝するべきだ」

　しばらく歩くと、要人専用エレベーターの前に到着した。壁の顔認証システムが稼働し、認証音が静かに鳴った。

「VIPルームまであと少しです」

　セキュリティーのひとりがジャスティンらに告げた。

　ジャスティンは背後のエリノアをちらりと見て、肩をすくめていった。

「今夜、ガーデンを震わそう」

　エリノアが彼の腕に軽く触れ、優しく笑いかけた。

「期待してるわ、ジャスティン」

　三人は静かにエレベーターに乗り込み、VIPルームへと向かった。

  

場面　トットラーメン　アナ、ミカ、車列

 

—— 赤、黄色、青 ——

　イースト52丁目に小雨が舞い始めたのは、午後七時を少し過ぎた頃だった。

　アナは、トットラーメンの隣にある古いビルの壁面にもたれ、右手に見える十字路の信号をぼんやりと眺めていた。蒸し返すような湿気がコンクリートにまとわりつき、行き交う人々の足取りもどこか重たかった。

　信号が青に変わった。額の汗をハンカチで拭いながら、アナが目を細めると、十字路の向こうにカナの姿が見えた。彼女は手を振りながら、笑顔でこちらに駆け出してくる。

　そのとき、空気がふいに変わった。十字路の向こうから、黒いSUVの車列が音もなく滑り込んできた。先頭車両の到着から、最後尾の装甲リムジンが去るまでの数十秒間、交差点は完全に封鎖され、誰も通ることができなかった。

　車列が去ると、信号が切り替わり、ふたたび人の流れが戻り、動き出した。

　カナがその人波の中からふたたび現れ、手を振った。

　展示を終えたアナたちは、ミカの車に荷物を積み終えたあと、マンハッタンへ移動していた。

　アナの夫アルジュンは、ウィリアムズバーグにあるAI・クラウド・サイバーセキュリティを手がける複合企業「ルミナテック・イノベーションズ」に勤めている。今日は休日だったが、彼だけハドソンヤードで会議があり、アナらとは別行動だった。

　トットラーメンはその近くにあり、以前ミカに連れてきてもらってから、アナたち夫婦のお気に入りになっていた。

　「おまたせ。今日は朝から素敵だったね」

　息を切らせながら駆け寄ったミカが、そう言った。

　“素敵”というのは、今朝の高級スーツをまとった二人の男のことだ。

　アナは興味なさそうに答えた。

　「そうね。ミカはああいう男性が好み？」

　ミカは首をすくめ、笑って言った。

　「うーん、かなり遠い存在かな。私は、すぐ実家に帰れるくらいの距離感が好き」

　二人は笑い合いながら、ラーメン店の引き戸を開け、カウンターに並んで腰掛けた。店内は週末のため、アジア系の家族で賑わっていた。ミカの聞き慣れた日本語が遠くのカウンターから聞こえてくる。

　アナのiPhoneが震えた。アルジュンからのビデオ通話だった。

　画面をタッチすると、アルジュンが申し訳なさそうな表情で映った。

　「会議が延びてる。少し遅れるから、先に食べててくれ」

　アナは、静かに答えた。

「気をつけて来てね。さっきすごい車の軍団が流れていったわよ」

　アルジュンは、即答した。

「今日はガーデンで、共和党の大会があるらしい。次期大統領候補が立つらしいよ」

　傍で聞いていたミカが深々と頷きながら、同意した。

「なんか朝から物々しいのよね。いつもの週末と違うわ」

 

ーーーーーーーーー

 

場面　レッドフック１　アミール、ラフィ

  

　レッドフックは、ブルックリンの中でも異質だった。

　高層ビルの影に守られ、風雨に洗われた赤レンガの倉庫と錆びた港湾クレーンが、風に軋んでいる街だ。やってくる潮の匂いが重なるたびに上塗りされ、倉庫の鉄の扉に赤錆を浮かせていく。

　鍵の壊れたフェンスの向こう、何年も使われていなかった倉庫の扉が静かに開いた。

　アミールは一歩踏み入れ、光のない空間に目を慣らした。コンクリートに染み込んだ油の臭いが鼻をついた。

「ここから始めよう」

　その声に、ラフィが黙って頷いた。

　ふたりが初めてここにやってきたのは５年前の冬だ。イスラエルによってガザ地区ですべてを失った二人は、合法的にエジプトからトルコを経由し、メキシコの南部タパチュラへ行き、コヨーテと呼ばれる密入国請負人と接触した。ラフィは密入国業者へ一人あたり１２，０００ドルを支払った。すべて、北朝鮮経由でハッキングした仮想通貨での支払いだ。金の出どころは、北朝鮮系ハッカー集団を通じて奪ったコインだった。アミールの手でコードが組まれ、記録は消された。彼らは、血を流さずに数字を流して国境を超えたのだ。その後、国境のフェンスを夜に潜り、陸路でアメリカに入った。

　テキサスの夜空は、彼らが見たことのないほど青黒かった。低く、澄んだ深い青の美しさは、彼らの胸にいくらかの希望を与えていたが、それ以上に憎しみの強さが上回っていた。

The sexy 4 buckled sandals have her feet and ankles strapped beautifully, imprisoning them with white patent leather. The heavy leather cuffs with their straps pulled tightly are secured in place. She tries to flex her feet but they won't move, she can only wiggle a few of her toes, the sandals are too snug. She then tries to move her ankles but strains against the double buckled cuff which encircles her lower leg. She looks at the devices placed upon her and gives up, the wide 4 strapped calf cuffs are overwelmingly restrictive. The only movement she can muster is a slight toe out as her calves are bolted together. Little does she know that in the next few days the front of the sandals will be connected by a metal bar and extensions will be made to brace her legs together entirely. I can make a bondage device for you that you have only dreamed of. PLEASE LEAVE A COMMENT as I am curious to the attraction to braces and this type of bondage. These are for sale. As usual, I can make these for you as well as any other type of leather and/or metal bondage device you can think of. I can also make you "conventional" orthopedic leg and body braces as well as "bondage" style braces, contact me at my1970junk@msn.com.

I named this one 'The Device' because that's what they call the mysterious Egyptian contraption in the movie 'Stargate' before they find out what it actually is.

 

I kind of feel the same about this weird gizmo that lives outside Glasgow Science Centre. If anyone has any ideas about what this is, what it does or who designed it, I would love to hear more.

 

It may well be a covert transmitter to Science Centre security who appeared on the scene right after I took this shot and said I couldn't take photos. When I questioned this he made some lame excuse about the management of the Science Centre chasing me because they don't like people taking photos so close to the BBC TV studios.....eh?

 

Maybe 'The Device' was actually his spaceship.....

Happy Valentina's Day! 🚀 👩‍🚀 💫

 

Today is the 57th anniversary of the first woman in space — Russia's Valentina Tereshkova on Vostok 6, a scary bullet of a capsule that could not make a soft landing, necessitating a skydive leap during reentry (just as Yuri Gagarin had to do).

 

She was 26 at the time and an amateur skydiver. She is the youngest female astronaut and the only woman to fly solo. To date, only 12% of astronauts have been women, despite being arguably better suited for the job. That should change.

 

After the flight of Yuri Gagarin in 1961, Nikolai Kamanin, director of cosmonaut training, read in American media that female pilots were training to be astronauts. In his diary, he wrote, "We cannot allow that the first woman in space will be American. This would be an insult to the patriotic feelings of Soviet women." Approval was granted for five female cosmonauts in the next group, which would begin training in 1963. To increase the odds of sending a Soviet woman into space first, the female cosmonauts began their training before the males.

 

With a single flight, she logged more flight time than the combined times of all American astronauts who had flown before that date.

 

Her call sign in this flight was Chaika (Russian: Ча́йка, or 'Seagull'), later commemorated as the name of an asteroid, 1671 Chaika. After her launch, she radioed down:

 

"It is I, Seagull! Everything is fine. I see the horizon; it's a sky blue with a dark strip. How beautiful the Earth is"

— Wikipedia

 

As planned in all Vostok missions, Tereshkova ejected from the capsule during its descent at about four miles above Kazakhstan and made a parachute landing, quite a thrill ride for this skydiver!

 

She had dinner with some local villagers in the Altai Krai who helped her to get out of her spacesuit.

 

Her flight became Cold War propaganda to demonstrate the superiority of communism. At the 1963 World Congress of Women, Soviet leader Nikita Khrushchev used Tereshkova's voyage to declare the USSR had achieved equality for women.

 

I bought this in France from Tereshkova’s instructor at the Zhukovsky Air Force Engineering Academy. His translated description: "This is an angle measuring device of the Russian aerospace for astronomic navigation, especially for calculation of flight angles. It was personally used by the Soviet cosmonaut Valentina Tereshkova. It is the model CMK 3 numbered 2416305 (badge on the device). The device still possesses the original leather strap. It consists of a turning wheel that is marked with degree values. Once the zero point on the scale is adjusted to a certain height, the orbs’ and targets’ location can be measured. In 1963, Tereshkova was the first woman to fly into space and remained the only woman in space until Svetlana Savitskaya’s flight in 1982. The device is in good condition with traces of use. The dimensions are 12 x 19.5 x 6 cm (height x width x depth)."
