The morning sunrise in Condobolin in far western NSW starts to warm up the town as VL362, VL353 and GL109 shunt 8890 back onto the mainline, having stabled the previous night in the yard after traveling from Broken Hill. The train consisted of CQMY wagons being transferred from Bowmans in South Australia to Bathurst and was operated by Sydney Rail Services.
The engines would travel light engine to Goulburn as D890 after dropping the wagons off the following day.

Using Energy Efficiently
For all the energy required to propel a vehicle, not all of it makes it to the wheels. Some of it is lost to friction and heat. Vehicle inefficiency can be classified into two categories of losses: road-load and energy conversion. At Tesla, careful attention is given to both to achieve the maximum range. The Tesla Roadster leverages both an incredible electric powertrain and an engineer’s obsession with efficiency to be the most efficient production sports car on the market today.
London Drive the Future
In 1982 Mercedes-Benz released the production version of more than a decade's research into developing a compact format, efficient and safe luxury car. The name '190' referred back to the 1950 and 60s versions of 'reduced power output' models of their mainstream saloon car range. The 190E specified a fuel-injected 2.0 litre, four cylinder engine, whilst a 190 model, without the 'E' (for einspritz' appellation, referred to the same engine, but using a carburetor.
This is the version most commonly seen in taxis, along with a 2.0 litre 4-cylinder diesel, with even less power......
Then something strange happened within the halls of Mercedes-Benz....
190E 2.3-16 & 2.5-16 "Cosworth":
In the late 1970s, Mercedes competed in rallying with the big V8-powered Coupés of the R107 Series, mainly the light-weight Mercedes 450 SLC 5.0. Mercedes wished to take the 190 E rallying, and asked British engineering company Cosworth to develop an engine with 320 bhp (239 kW) for the rally car. This project was known as project "WAA' by Cosworth". During this time, the Audi Quattro with its all-wheel drive and turbocharger was launched, making the 2.3-16v appear outclassed. With a continued desire to compete in high-profile motor sport with the 190, and also now an engine to do it with, Mercedes turned to the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) motor sport series instead. Cars racing in this championship, however, had to be based on a roadgoing model. Mercedes therefore had to put into series production a 190 fitted with a detuned version of the Cosworth engine. This high-performance model was known as the 190 E 2.3-16, and debuted at the Frankfurt Auto Show in September 1983, after its reputation had already been established. Three cars, only slightly cosmetically altered, had set three world records in August at the Nardo testing facility in Italy, recording a combined average speed of 154.06 mph (247.94 km/h) over the 50,000 km endurance test, and establishing twelve international endurance records. The Mercedes 190-E Cosworth was also featured on the second episode in series fifteen of the popular car show Top Gear.
Engin:
2.5-16 Cosworth
The Cosworth engine was based on the M102 four cylinder 2.3-litre 8-valve 136 hp (101 kW) unit already fitted to the 190- and E-Class series. Cosworth developed the cylinder head, "applying knowledge we've learnt from the DFV and BDA." It was made from light alloy using Coscast's unique casting process and brought with it dual overhead camshafts and four valves per cylinder, meaning 16 valves total which were developed to be the "largest that could practically be fitted into the combustion chamber".
In roadgoing trim,the 2.3 L 16-valve engine made "185 hp (138 kW) at 6,200 rpm and 174 lb·ft (236 N·m) at 4,500 rpm. The oversquare 95.50 x 80.25 mm bore and stroke dimensions ensuring that it revs easily up to the 7000 rpm redline". Acceleration from 0–100 km/h (62 mph) was less than eight seconds, and the top speed was 230 km/h (143 mph).
US-Specification cars had a slightly reduced compression ratio (9.7:1 instead of 10.5:1), and were rated at 167 hp (125 kW) @ 5800 rpm and 162 lb·ft (220 N·m) @ 4750.
The roadgoing version of the engine was reconfigured with reduced inlet and exhaust port sizes, different camshaft profiles, no dry sump configuration and Bosch K-jetronic replacing the specialised Kugelfischer fuel injection. These changes helped bring power down to the required 185 bhp (138 kW) specification, but still resulted in a "remarkably flexible engine, with a very flat torque curve and a wide power band". The heads for the engines were cast at Cosworth's Coscast foundry in Worcester and sent to Germany to be fitted to the rest of the engine, parts of which were different from the standard 2.3 including light pressed alloy pistons, and rings designed to withstand higher engine speeds, whilst con-rods, bearings and bearing caps were found to be strong enough as standard and left unaltered.
16v differences:
Due to their performance, the 16-valve cars were different from the other 190 models. The body kit on the 2.3-16 and 2.5-16 reduced the drag coefficient to 0.32, one of the lowest CD values on a four-door saloon of the time, whilst also reducing lift at speed. The steering ratio was quicker and the steering wheel smaller than that on other 190s, whilst the fuel tank was enlarged from 55 to 70 L. The Getrag 5-speed manual gearbox was unique to the 16-valve and featured a 'racing' gear pattern with 'dog-leg' first gear, left and down from neutral. This meant that the remaining 2nd, 3rd, 4th and 5th gears were in a simple H pattern allowing fast and easy selection. The gearchange quality was, however, noted as "notchy, baulky", criticisms which weren't levelled at the BMW M3 (E30) which shared the same gearbox. The pattern is also unusual in that the driver engages reverse by shifting left and up from neutral, as for first gear in a conventional pattern. This was demonstrated in a Top Gear episode (S15E02) where James May took a 190E 2.3-16 Cosworth and repeatedly confused reverse and first gear. An oil cooler was fitted to ensure sufficient oil cooling for the inevitable track use many of these cars were destined for.
The strictly four-seater interior had Recaro sports seats with strong side bolsters for front and rear passengers. 3 extra dials - an oil temperature gauge, stopwatch and voltmeter - were included in the centre console. The 190 E 2.3-16 was available in only two colours, Blue-Black metallic (Pearl Black in the US), and Smoke Silver. The 2.5-16 added Almandine Red and Astral Silver.
All 2.3-16-valve 190 models are fitted with a Limited Slip Differential (LSD) as standard. They were also available with Mercedes' ASD system which was standard equipment on the 2.5-16v. The ASD is an electronically controlled, hydraulically locking differential which activates automatically when required. The electronic control allows varied amounts of differential lock from the standard 15% right up to 100%. It is not a traction control system however, and can only maximize traction rather than prevent wheel spin. Activation of the ASD system is indicated by an illuminating amber triangle in the speedometer.
The suspension on 16-valve models is very different from the standard 190 (W201). As well as being lower and stiffer, it has quicker dampers, larger anti-roll bars, harder bushings and hydraulic Self-levelling suspension (SLS) on the rear. This allows the rear ride height to remain constant even when the car is fully loaded.
At the inauguration of the new, shorter Nürburgring in 1984, a race with identical cars was held, with former and current F1 pilots at the wheel. A then unknown Ayrton Senna took first place.
Private Teams such as AMG later entered the 2.3-16 in touring cars races, especially the DTM. In the late 1980s, the 2.5-16 (never released in the United States) raced many times, against the similar BMW M3 and even the turbocharged Ford Sierra RS Cosworth.
Evolution models:
2.5-16 Evolution II
With the debut of the BMW M3 Sport Evolution, Mercedes' direct competitor, it became obvious that the 2.5-16 needed a boost for the circuit. In March 1989, the 190 E 2.5-16 Evolution debuted at the Geneva Auto Show. The Evo I, as it came to be called, had a new spoiler and wider wheel arches. Many changes were made to under-the-skin components such as brakes and suspension. There was a full SLS suspension allowing vehicle ride height to be adjusted from an interior switch. All were intended to allow the Evolution cars to be even more effective round a track.
The Evo I's output is similar to the 202 bhp (151 kW) of the "regular" 2.5-16. However this car had a redesigned engine of similar capacity but, most importantly, a shorter stroke and bigger bore which would allow for a higher rev limit and improved top-end power capabilities. Additional changes stretch to "rotating masses lightened, lubrication improved and cam timing altered". Cosworth also list a project code "WAC" for the development of the short-stroke Evolution engine.
Only 502 units of the Evolution model were produced for homologation in compliance with DTM rules. For those customers desiring even more performance, a PowerPack option engineered by AMG was available for DM 18,000. The PowerPack option included hotter camshafts, a larger diameter throttle body, more aggressive ignition and fuel management as well as optimization of the intake and exhaust systems. The net result was an additional 30 bhp (22 kW).
In March 1990, at the Geneva Auto Show, the 190 E 2.5-16 Evolution II was shown. With the success of the first Evolution model, this model's 502-unit production was already sold before it was unveiled.
The "Evo II" included the AMG PowerPack fitted to the same short-stroke 2.5 engine as the Evolution, as well as a full SLS suspension allowing vehicle ride height to be adjusted from an interior switch. An obvious modification to the Evolution II is a radical body kit (designed by Prof. Richard Eppler from the University of Stuttgart) with a large adjustable rear wing, rear window spoiler, and Evolution II 17-inch wheels. The kit served an aerodynamic purpose — it was wind tunnel tested to reduce drag to 0.29, while at the same time increasing downforce. Period anecdotes tell of a BMW executive who was quoted as saying "if that rear wing works, we'll have to redesign our wind tunnel." The anecdote claims that BMW did.
As mentioned 500 were made in "blauschwarz" blue/black metallic. But the last two, numbers 501 and 502 were made in astral silver.

An important thing to remember is that even though pixel sizes keep getting smaller and smaller, the technology is advancing, so the smaller pixels are more efficient at collecting light. For instance, the Sony A7rII is back-illuminated which allows more photons to hit the sensor. Semiconductor technology is always advancing, so the brilliant engineers are always improving the signal/noise ratio. Far higher pixel counts, as well as better dynamic ranger, are thus not only possible, but the future!

View your artistic mission into photography as an epic odyssey of heroic poetry! Take it from Homer in Homer's Odyssey: "Tell me, O muse, of that ingenious hero who travelled far and wide after he had sacked the famous town of Troy. Many cities did he visit, and many were the nations with whose manners and customs he was acquainted; moreover he suffered much by sea while trying to save his own life and bring his men safely home; but do what he might he could not save his men, for they perished through their own sheer folly in eating the cattle of the Sun-god Hyperion; so the god prevented them from ever reaching home. Tell me, too, about all these things, O daughter of Jove, from whatsoever source you may know them. " --Samuel Butler Translation of Homer's Odyssey

The loco is now at the Ribble Steam Railway, Preston and their website shows the following information:
'Efficient' was built at the Caledonia works of Andrew Barclay & Sons in Kilmarnock. It is a standard Barclay saddle tank with 14" x 22" cylinders and 3' 5" driving wheels. Painted in the Kilmarnock firms usual green lined livery and lettering, it spent it's entire working life at McKechnie Brothers' copper smelting works at Widnes. It shared the duties here with a smaller Barclay engine named 'Economic', which failed to live up to it's name and was scrapped in 1955. There were also two 100h.p. Sentinels as well.
When no longer required at the copper works 'Efficient' was purchased by the Liverpool Locomotive Preservation Group and moved to Seacombe in July 1969. From here, it worked the two Docker railtours in 1971 and 1972, double-headed with 'Lucy'. 'Efficient' moved to Southport in July 1973, where she had the distinction of being the first steam locomotive to enter the newly formed museum. She was fitted with a new inner firebox in 1981, and was a regular performer at Southport until the late 1990s when the site closed, eventually arriving at Preston on 27th July 1999. Efficient's last public steaming was in April 2000 as she took part in the closing celebrations at Shelton Steelworks in Stoke. A firm favourite amongst the crews at the museum, investigation was carried out during the summer of 2005 to bring the loco back into service.
Unfortunately, due to the extent of the work required on the boiler, she will have to wait her turn. She is on view in the museum in a 'as in industrial use' condition.
Some background:
Simple, efficient and reliable, the Regult (リガード, Rigādo) was the standard mass production mecha of the Zentraedi forces. Produced by Esbeliben at the 4.432.369th Zentraedi Fully Automated Weaponry Development and Production Factory Satellite in staggering numbers to fill the need for an all-purpose mecha, this battle pod accommodated a single Zentraedi soldier in a compact cockpit and was capable of operating in space or on a planet's surface. The Regult saw much use during Space War I in repeated engagements against the forces of the SDF-1 Macross and the U.N. Spacy, but its lack of versatility against superior mecha often resulted in average effectiveness and heavy losses. The vehicle was regarded as expendable and was therefore cheap, simple, but also very effective when fielded in large numbers. Possessing minimal defensive features, the Regult was a simple weapon that performed best in large numbers and when supported by other mecha such as Gnerl Fighter Pods. Total production is said to have exceeded 300 million in total.
The cockpit could be accesses through a hatch on the back of the Regult’s body, which was, however, extremely cramped, with poor habitability and means of survival. The giant Zentraedi that operated it often found themselves crouching, with some complaining that "It would have been easier had they just walked on their own feet". Many parts of the craft relied on being operated on manually, which increased the fatigue of the pilot. On the other hand, the overall structure was extremely simple, with relatively few failures, making operational rate high.
In space, the Regult made use of two booster engines and numerous vernier thrusters to propel itself at very high speeds, capable of engaging and maintaining pace with the U.N. Spacy's VF-1 Valkyrie variable fighter. Within an atmosphere, the Regult was largely limited to ground combat but retained high speed and maneuverability. On land, the Regult was surprisingly fast and agile, too, capable of closing with the VF-1 variable fighter in GERWALK flight (though likely unable to maintain pace at full GERWALK velocity). The Regult was not confined to land operations, though, it was also capable of operating underwater for extended periods of time. Thanks to its boosters, the Regult was capable of high leaping that allowed the pod to cover long distances, surprise enemies and even engage low-flying aircraft.
Armed with a variety of direct-fire energy weapons and anti-personnel/anti-aircraft guns, the Regult offered considerable firepower and was capable of engaging both air and ground units. It was also able to deliver powerful kicks. The armor of the body shell wasn't very strong, though, and could easily be penetrated by a Valkyrie's 55 mm Gatling gun pod. Even bare fist attacks of a VF-1 could crack the Regult’s cockpit or immobilize it. The U.N. Spacy’s MBR-07 Destroid Spartan was, after initial battel experience with the Regult, specifically designed to engage the Zentraedi forces’ primary infantry weapon in close-combat.
The Regult was, despite general shortcomings, a highly successful design and it became the basis for a wide range of specialized versions, including advanced battle pods for commanders, heavy infantry weapon carriers and reconnaissance/command vehicles. The latter included the Regult Tactical Scout (リガード偵察型). manufactured by electronics specialist Ectromelia. The Tactical Scout variant was a deadly addition to the Zentraedi Regult mecha troops. Removing all weaponry, the Tactical Scout was equipped with many additional sensor clusters and long-range detection equipment. Always found operating among other Regult mecha or supporting Glaug command pods, the Scout was capable of early warning enemy detection as well as ECM/ECCM roles (Electronic Countermeasures/Electronic Counter-Countermeasures). In Space War I, the Tactical Scout was utilized to devastating effect, often providing radar jamming, communication relay and superior tactical positioning for the many Zentraedi mecha forces.
At the end of Space War I in January 2012, production of the Regult for potential Earth defensive combat continued when the seizure operation of the Factory Satellite was executed. After the war, Regults were used by both U.N. Spacy and Zentraedi insurgents. Many surviving units were incorporated into the New U.N. Forces and given new model numbers. The normal Regult became the “Zentraedi Battle Pod” ZBP-104 (often just called “Type 104”) and was, for example, used by Al-Shahal's New U.N. Army's Zentraedi garrison. The related ZBP-106 was a modernized version for Zentraedi commanders, with built-in boosters, additional Queadluun-Rhea arms and extra armaments. These primarily replaced the Glaug battle pod, of which only a handful had survived. By 2067, Regult pods of all variants were still in operation among mixed human/Zentraedi units.

The kit and its assembly:
I had this kit stashed away for a couple of years, together with a bunch of other 1:100 Zentraedi pods of all kinds and the plan to build a full platoon one day – but this has naturally not happened so far and the kits were and are still waiting. The “Reconnaissance & Surveillance” group build at whatifmodellers.com in August 2021 was a good occasion and motivation to tackle the Tactical Scout model from the pile, though, as it perfectly fits the GB’s theme and also adds an exotic science fiction/anime twist to the submissions.
The kit is an original ARII boxing from 1983, AFAIK the only edition of this model. One might expect this kit to be a variation of the 1982 standard Regult (sometimes spelled “Reguld”) kit with extra parts, but that’s not the case – it is a new mold with different parts and technical solutions, and it offers optional parts for the standard Regult pod as well as the two missile carrier versions that were published at the same time, too. The Tactical Scout uses the same basis, but it comes with parts exclusive for this variant (hull and a sprue with the many antennae and sensors).
I remembered from a former ARII Regult build in the late Eighties that the legs were a wobbly affair. Careful sprue inspection revealed, however, that this second generation comes with some sensible detail changes, e. g. the feet, which originally consisted of separate toe and heel sections (and these were hollow from behind/below!). To my biggest surprise the knees – a notorious weak spot of the 1st generation Regult kit – were not only held by small and flimsy vinyl caps anymore: These were replaced with much bigger vinyl rings, fitted into sturdy single-piece enclosures made from a tough styrene which can even be tuned with small metal screws(!), which are included in the kit. Interesting!
But the joy is still limited: even though the mold is newer, fit is mediocre at best, PSR is necessary on every seam. However, the good news is that the kit does not fight with you. The whole thing was mostly built OOB, because at 1:100 there's little that makes sense to add to the surface, and the kit comes with anything you'd expect on a Regult Scout pod. I just added some lenses and small stuff behind the large "eye", which is (also to my surprise) a clear part. The stuff might only appear in schemes on the finished model, but that's better than leaving the area blank.
Otherwise, the model was built in sub-sections for easier painting and handling, to be assembled in a final step – made possible by the kit’s design which avoids the early mecha kit’s “onion layer” construction, except for the feet. This is the only area that requires some extra effort, and which is also a bit tricky to assemble.
However, while the knees appear to be a robust construction, the kit showed some material weakness: while handling the leg assembly, one leg suddenly came off under the knees - turned out that the locator that holds the knee joint above (which I expected to be the weak point) completely broke off of the lower leg! Weird damage. I tried to glue the leg into place, but this did not work, and so I inserted a replacement for the broken. This eventually worked.
Painting and markings:
Colorful, but pretty standard and with the attempt to be authentic. However, information concerning the Regults’ paint scheme is somewhat inconsistent. I decided to use a more complex interpretation of the standard blue/grey Regult scheme, with a lighter “face shield” and some other details that make the mecha look more interesting. I used the box art and some screenshots from the Macross TV series as reference; the Tactical Scout pod already appears in episode #2 for the first time, and there are some good views at it, even though the anime version is highly simplified.
Humbrol enamels were used, including 48 (Mediterranean Blue), 196 (RAL 7035, instead of pure white), 40 (Pale Grey) and 27 (Sea Grey). The many optics were created with clear acrylics over a silver base, and the large frontal “eye” is a piece of clear plastic with a coat of clear turquoise paint, too.
The model received a black ink washing to emphasize details, engraved panel lines and recesses, as well as some light post-shading through dry-brushing. Some surface details were created with decal stripes, e. g. on the upper legs, or with a black fineliner, and some color highlights were distributed all over the hull, e. g. the yellowish-beige tips of the wide antenna or the bright blue panels on the upper legs.
The decals were taken OOB, and thanks to a translation chart I was able to decipher some of the markings which I’d interpret as a serial number and a unit code – but who knows?
Finally, the kit received an overall coat of matt acrylic varnish and some weathering/dust traces around the feet with simple watercolors – more would IMHO look out of place, due to the mecha’s sheer size in real life and the fact that the Regult has to be considered a disposable item. Either it’s brand new and shiny, or busted, there’s probably little in between that justifies serious weathering which better suits the tank-like Destroids.
A “normal” build, even though the model and the topic are exotic enough. This 2nd generation Regult kit went together easier than expected, even though it has its weak points, too. However, material ageing turned out to be the biggest challenge (after all, the kit is almost 40 years old!), but all problems could be overcome and the resulting model looks decent – and it has this certain Eighties flavor! :D
The BMW i8, first introduced as the BMW Concept Vision Efficient Dynamics, is a plug-in hybrid sports car developed by BMW. The 2015 model year BMW i8 has a 7.1 kWh lithium-ion battery pack that delivers an all-electric range of 37 km (23 mi) under the New European Driving Cycle (NEDC).[5] Under the United States Environmental Protection Agency (EPA) cycle, the range in EV mode is 24 km (15 mi) with a small amount of gasoline consumption.
The BMW i8 can go from 0–100 km/h (0 to 60 mph) in 4.4 seconds and has a top speed of 250 km/h (155 mph). The BMW i8 has a fuel efficiency of 2.1 L/100 km (134.5 mpg-imp; 112.0 mpg-US) under the NEDC test with carbon emissions of 49 g/km. EPA rated the i8 combined fuel economy at 76 equivalent (MPG-equivalent) (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent).
The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany. The production version of the BMW i8 was unveiled at the 2013 Frankfurt Motor Show. The i8 was released in Germany in June 2014. Deliveries to retail customers in the U.S. began in August 2014. Global cumulative sales totaled almost 4,500 units through June 2015.
History
The i8 is part of BMW's "Project i" and it is being marketed as a new brand, BMW i, sold separately from BMW or Mini. The BMW i3, launched for retail customers in Europe in the fourth quarter of 2013, was the first model of the i brand available in the market, and it was followed by the i8, released in Germany in June 2014 as a 2015 model year. Other i models are expected to follow.
The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany, In 2010, BMW announced the mass production of the Concept Vision Efficient Dynamics in Leipzig beginning in 2013 as the BMW i8. The BMW i8 gasoline-powered concept car destined for production was unveiled at the 2011 Frankfurt Motor Show. The production version of the BMW i8 was unveiled at the 2013 International Motor Show Germany. The following are the concept and pre-production models developed by BMW that precedeed the production version.
BMW Vision EfficientDynamics (2009)
BMW Vision EfficientDynamics concept car is a plug-in hybrid with a three cylinder turbodiesel engine. Additionally, there are two electric motors with 139 horsepower. It allows an acceleration to 100 km/h (62 mph) in 4.8 seconds and an electronically limited top speed of 250 km/h (160 mph).
According to BMW, the average fuel consumption in the EU test cycle (KV01) is 3.76 liters/100 kilometers, (75.1 mpg imp), and has a carbon dioxide emission rating of 99 grams per kilometer (1,3 l/100 km and 33g CO2/km ; EU-PHEV ECE-R101). The estimated all-electric range is 50 km (31 mi), and the 24-liter petrol tank extends the total vehicle range to up to 700 km (430 mi). The lightweight chassis is made mainly from aluminum. The windshield, top, doors and fenders are made from polycarbonate glass, with the body having a drag coefficient of 0.26.
The designers in charge of the BMW Vision EfficientDynamics Concept were Mario Majdandzic, Exterior Design and Jochen Paesen, Interior Design.
The vehicle was unveiled in 2009 International Motor Show Germany, followed by Auto China 2010.
BMW i8 Concept (2011)
BMW i8 Concept plug-in hybrid electric vehicle includes an electric motor located in the front axle powering the front wheels rated 96 kW (131 PS; 129 hp) and 250 N·m (184 lb·ft), a turbocharged 1.5-liter 3-cylinder gasoline engine driving rear wheels rated 164 kW (223 PS; 220 hp) and 300 N·m (221 lb·ft) of torque, with combined output of 260 kW (354 PS; 349 hp) and 550 N·m (406 lb·ft), a 7.2 kWh (26 MJ) lithium-ion battery pack that allows an all-electric range of 35 km (22 mi). All four wheels provide regenerative braking. The location of the battery pack in the energy tunnel gives the vehicle a low centre of gravity, enhancing its dynamics. Its top speed is electronically limited to 250 km/h (160 mph) and is expected to go from 0 to 100 km/h (0 to 60 mph) in 4.6 seconds. Under normal driving conditions the i8 is expected to deliver 80 mpg-US (2.9 L/100 km; 96 mpg-imp) under the European cycle. A full charge of the battery will take less than 2 hours using 220V. The positioning of the motor and engine over the axles results in optimum 50/50 weight distribution.
The vehicle was unveiled at the 2011 International Motor Show Germany, followed by CENTER 548 in New York City, 42nd Tokyo Motor Show 2011, 82nd Geneva Motor Show 2012, BMW i Born Electric Tour at the Palazzo delle Esposizioni at Via Nazionale 194 in Rome, Auto Shanghai 2013.

BMW i8 Concept Spyder (2012)
The BMW i8 Concept Spyder included a slightly shorter wheelbase and overall length over the BMW i8 Concept, carbon-fibre-reinforced plastic (CFRP) Life module, drive modules made primarily from aluminium components, interlocking of surfaces and lines, 8.8-inch (22.4 cm) screen display, off-white outer layer, orange tone naturally tanned leather upholstery.
The vehicle was unveiled in Auto China 2012 in Beijing and won Concept Car of the Year, followed by 83rd Geneva International Motor Show 2013.
The designer of the BMW i8 Concept Spyder was Richard Kim.
BMW i8 coupe prototype (2013)
The design of the BMW i8 coupe prototype was based on the BMW i8 Concept. The BMW i8 prototype has an average fuel efficiency of less than 2.5 L/100 km (113.0 mpg-imp; 94.1 mpg-US) under the New European Driving Cycle with carbon emissions of less than 59 g/km. The i8 with its carbon-fiber-reinforced plastic (CFRP) passenger cell lightweight, aerodynamically optimized body, and BMW eDrive technology offers the dynamic performance of a sports car, with an expected 0–100 km (0–60 mi) sprint time of less than 4.5 seconds using both power sources. The plug-in hybrid system of the BMW i8 comprises a three-cylinder, 1.5-liter BMW TwinPower turbo gasoline engine combined with BMW eDrive technology used in the BMW i3 and develops maximum power of 170 kW (230 hp). The BMW i8 is the first BMW production model to be powered by a three-cylinder gasoline engine and the resulting specific output of 115 kW (154 hp) per liter of displacement is on a par with high-performance sports car engines and is the highest of any engine produced by the BMW Group.
The BMW i8's second power source is a hybrid synchronous electric motor specially developed and produced by the BMW Group for BMW i. The electric motor develops maximum power of 131 hp (96 kW) and produces its maximum torque of around 320 N·m (240 lbf·ft) from standstill. Typical of an electric motor, responsive power is instantly available when starting and this continues into the higher load ranges. As well as providing a power boost to assist the gasoline engine during acceleration, the electric motor can also power the vehicle by itself. Top speed in electric mode is approximately 120 km/h (75 mph), with a maximum driving range of up to 35 km (22 mi). Linear acceleration is maintained even at higher speeds since the interplay between the two power sources efficiently absorbs any power flow interruptions when shifting gears. The BMW i8 has an electronically controlled top speed of 250 km (160 mi), which can be reached and maintained when the vehicle operates solely on the gasoline engine. The model-specific version of the high-voltage 7.2 lithium-ion battery has a liquid cooling system and can be recharged at a conventional household power socket, at a BMW i Wallbox or at a public charging station. In the US a full recharge takes approximately 3.5 hours from a conventional 120V, 12 amp household circuit or approximately 1.5 hours from a 220V Level 2 charger.
The driver can also select several driving modes: SPORT, COMFORT and ECO PRO. Using the gear selector, the driver can either select position D for automated gear selection or can switch to SPORT mode. SPORT mode offers manual gear selection and at the same time switches to very sporty drive and suspension settings. In SPORT mode, the engine and electric motor deliver extra performance, accelerator response is faster and the power boost from the electric motor is maximized. And to keep the battery topped up, SPORT mode also activates maximum energy recuperation during overrun and braking as the electric motor’s generator function, which recharges the battery using kinetic energy, switches to a more powerful setting. The Driving Experience Control switch on the center console offers a choice of two settings. On starting, COMFORT mode is activated, which offers a balance between sporty performance and fuel efficiency, with unrestricted access to all convenience functions. Alternatively, the ECO PRO mode can be engaged, which, on the BMW i8 as on other models, supports an efficiency-optimized driving style. On this mode the powertrain controller coordinates the cooperation between the gasoline engine and the electric motor for maximum fuel economy. On deceleration, the intelligent energy management system automatically decides, in line with the driving situation and vehicle status, whether to recuperate braking energy or to coast with the powertrain disengaged. At the same time, ECO PRO mode also programs electrical convenience functions such as the air conditioning, seat heating and heated mirrors to operate at minimum power consumption, but without compromising safety. The maximum driving range of the BMW i8 on a full fuel tank and with a fully charged battery is more than 500 km (310 mi) in COMFORT mode, which can be increased by up to 20% in ECO PRO mode. The BMW i8’s ECO PRO mode can also be used during all-electric operation. The vehicle is then powered solely by the electric motor. Only if the battery charge drops below a given level, or under sudden intense throttle application such as kickdown, is the internal combustion engine automatically activated.
The vehicle was unveiled in BMW Group's Miramas test track in France.
Production version
The production BMW i8 was designed by Benoit Jacob. The production version was unveiled at the 2013 International Motor Show Germany, followed by 2013 Les Voiles de Saint-Tropez. It features butterfly doors, head-up display, rear-view cameras and partially false engine noise. Series production of customer vehicles began in April 2014. It is the first production car with laser headlights, reaching further than LED lights.
The i8 has a low vehicle weight of 1,485 kg (3,274 lb) (DIN kerb weight) and a low drag coefficient (Cd) of 0.26. In all-electric mode the BMW i8 has a top speed of 120 km/h (75 mph). In Sport mode the i8 delivers a mid-range acceleration from 80 to 120 km/h (50 to 75 mph) in 2.6 seconds. The electronically controlled top speed is 250 km/h (160 mph).
Range and fuel economy[edit]
The production i8 has a 7.1 kWh lithium-ion battery pack with a usable capacity of 5.2 kWh and intelligent energy management that delivers an all-electric range of 37 km (23 mi) under the NEDC cycle. Under the EPA cycle, the range in EV mode is 15 mi (24 km), with a gasoline consumption of 0.1 gallons per 100 mi, and as a result, EPA's all-electric range is zero. The total range is 330 mi (530 km).
The production version has a fuel efficiency of 2.1 L/100 km (134.5 mpg-imp; 112.0 mpg-US) under the NEDC test with carbon emissions of 49 g/km.[5] Under EPA cycle, the i8 combined fuel economy in EV mode was rated 76 equivalent (MPG-equivalent) (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent), with an energy consumption of 43 kW-hrs/100 mi and gasoline consumption of 0.1 gal-US/100 mi. The combined fuel economy when running only with gasoline is 28 mpg-US (8.4 L/100 km; 34 mpg-imp), 28 mpg-US (8.4 L/100 km; 34 mpg-imp) for city driving, and 29 mpg-US (8.1 L/100 km; 35 mpg-imp) in highway.
The U.S. Environmental Protection Agency's 2014 edition of the "Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends" introduced utility factors for plug-in hybrids to represent the percentage of miles that will be driven using electricity by an average driver, in electric only or blended modes. The BMW i8 has a utility factor in EV mode of 37%, compared with 83% for the BMW i3 REx, 66% for the Chevrolet Volt, 65% for the Cadillac ELR, 45% for the Ford Energi models, 43% for the McLaren P1, 39% for the Porsche Panamera S E-Hybrid, and 29% for the Toyota Prius PHV.

The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany. The production version of the BMW i8 was unveiled at the 2013 Frankfurt Motor Show. The i8 was released in Germany in June 2014. Deliveries to retail customers in the U.S. began in August 2014. Global cumulative sales totaled almost 4,500 units through June 2015.
History
The i8 is part of BMW's "Project i" and it is being marketed as a new brand, BMW i, sold separately from BMW or Mini. The BMW i3, launched for retail customers in Europe in the fourth quarter of 2013, was the first model of the i brand available in the market, and it was followed by the i8, released in Germany in June 2014 as a 2015 model year. Other i models are expected to follow.
The initial turbodiesel concept car was unveiled at the 2009 International Motor Show Germany, In 2010, BMW announced the mass production of the Concept Vision Efficient Dynamics in Leipzig beginning in 2013 as the BMW i8. The BMW i8 gasoline-powered concept car destined for production was unveiled at the 2011 Frankfurt Motor Show. The production version of the BMW i8 was unveiled at the 2013 International Motor Show Germany. The following are the concept and pre-production models developed by BMW that precedeed the production version.

BMW i8 Concept (2011)
BMW i8 Concept plug-in hybrid electric vehicle includes an electric motor located in the front axle powering the front wheels rated 96 kW (131 PS; 129 hp) and 250 N·m (184 lb·ft), a turbocharged 1.5-liter 3-cylinder gasoline engine driving rear wheels rated 164 kW (223 PS; 220 hp) and 300 N·m (221 lb·ft) of torque, with combined output of 260 kW (354 PS; 349 hp) and 550 N·m (406 lb·ft), a 7.2 kWh (26 MJ) lithium-ion battery pack that allows an all-electric range of 35 km (22 mi). All four wheels provide regenerative braking. The location of the battery pack in the energy tunnel gives the vehicle a low centre of gravity, enhancing its dynamics. Its top speed is electronically limited to 250 km/h (160 mph) and is expected to go from 0 to 100 km/h (0 to 60 mph) in 4.6 seconds. Under normal driving conditions the i8 is expected to deliver 80 mpg-US (2.9 L/100 km; 96 mpg-imp) under the European cycle. A full charge of the battery will take less than 2 hours using 220V. The positioning of the motor and engine over the axles results in optimum 50/50 weight distribution.

sur la ligne 69 à destination de Saint-Alban – Centre Commercial, avenue de Villemur, Saint-Alban (Haute-Garonne (31), Occitanie, France, FR)
In 1982 Mercedes-Benz released the production version of more than a decade's research into developing a compact format, efficient and safe luxury car. The name '190' referred back to the 1950 and 60s versions of 'reduced power output' models of their mainstream saloon car range. The 190E specified a fuel-injected 2.0 litre, four cylinder engine, whilst a 190 model, without the 'E' (for einspritz' appellation, referred to the same engine, but using a carburetor.
This is the version most commonly seen in taxis, along with a 2.0 litre 4-cylinder diesel, with even less power......
Then something strange happened within the halls of Mercedes-Benz....
190E 2.3-16 "Cosworth":
In the late 1970s, Mercedes competed in rallying with the big V8-powered Coupés of the R107 Series, mainly the light-weight Mercedes 450 SLC 5.0. Mercedes wished to take the 190 E rallying, and asked British engineering company Cosworth to develop an engine with 320 bhp (239 kW) for the rally car. This project was known as project "WAA' by Cosworth". During this time, the Audi Quattro with its all-wheel drive and turbocharger was launched, making the 2.3-16v appear outclassed. With a continued desire to compete in high-profile motor sport with the 190, and also now an engine to do it with, Mercedes turned to the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) motor sport series instead. Cars racing in this championship, however, had to be based on a roadgoing model. Mercedes therefore had to put into series production a 190 fitted with a detuned version of the Cosworth engine. This high-performance model was known as the 190 E 2.3-16, and debuted at the Frankfurt Auto Show in September 1983, after its reputation had already been established. Three cars, only slightly cosmetically altered, had set three world records in August at the Nardo testing facility in Italy, recording a combined average speed of 154.06 mph (247.94 km/h) over the 50,000 km endurance test, and establishing twelve international endurance records. The Mercedes 190-E Cosworth was also featured on the second episode in series fifteen of the popular car show Top Gear.
Engine:
2.5-16 Cosworth
The Cosworth engine was based on the M102 four cylinder 2.3-litre 8-valve 136 hp (101 kW) unit already fitted to the 190- and E-Class series. Cosworth developed the cylinder head, "applying knowledge we've learnt from the DFV and BDA." It was made from light alloy using Coscast's unique casting process and brought with it dual overhead camshafts and four valves per cylinder, meaning 16 valves total which were developed to be the "largest that could practically be fitted into the combustion chamber".
In roadgoing trim,the 2.3 L 16-valve engine made "185 hp (138 kW) at 6,200 rpm and 174 lb·ft (236 N·m) at 4,500 rpm. The oversquare 95.50 x 80.25 mm bore and stroke dimensions ensuring that it revs easily up to the 7000 rpm redline". Acceleration from 0–100 km/h (62 mph) was less than eight seconds, and the top speed was 230 km/h (143 mph).
US-Specification cars had a slightly reduced compression ratio (9.7:1 instead of 10.5:1), and were rated at 167 hp (125 kW) @ 5800 rpm and 162 lb·ft (220 N·m) @ 4750.
The roadgoing version of the engine was reconfigured with reduced inlet and exhaust port sizes, different camshaft profiles, no dry sump configuration and Bosch K-jetronic replacing the specialised Kugelfischer fuel injection. These changes helped bring power down to the required 185 bhp (138 kW) specification, but still resulted in a "remarkably flexible engine, with a very flat torque curve and a wide power band". The heads for the engines were cast at Cosworth's Coscast foundry in Worcester and sent to Germany to be fitted to the rest of the engine, parts of which were different from the standard 2.3 including light pressed alloy pistons, and rings designed to withstand higher engine speeds, whilst con-rods, bearings and bearing caps were found to be strong enough as standard and left unaltered.
16v differences:
Due to their performance, the 16-valve cars were different from the other 190 models. The body kit on the 2.3-16 and 2.5-16 reduced the drag coefficient to 0.32, one of the lowest CD values on a four-door saloon of the time, whilst also reducing lift at speed. The steering ratio was quicker and the steering wheel smaller than that on other 190s, whilst the fuel tank was enlarged from 55 to 70 L. The Getrag 5-speed manual gearbox was unique to the 16-valve and featured a 'racing' gear pattern with 'dog-leg' first gear, left and down from neutral. This meant that the remaining 2nd, 3rd, 4th and 5th gears were in a simple H pattern allowing fast and easy selection. The gearchange quality was, however, noted as "notchy, baulky", criticisms which weren't levelled at the BMW M3 (E30) which shared the same gearbox. The pattern is also unusual in that the driver engages reverse by shifting left and up from neutral, as for first gear in a conventional pattern. This was demonstrated in a Top Gear episode (S15E02) where James May took a 190E 2.3-16 Cosworth and repeatedly confused reverse and first gear. An oil cooler was fitted to ensure sufficient oil cooling for the inevitable track use many of these cars were destined for.
The strictly four-seater interior had Recaro sports seats with strong side bolsters for front and rear passengers. 3 extra dials - an oil temperature gauge, stopwatch and voltmeter - were included in the centre console. The 190 E 2.3-16 was available in only two colours, Blue-Black metallic (Pearl Black in the US), and Smoke Silver. The 2.5-16 added Almandine Red and Astral Silver.
All 2.3-16-valve 190 models are fitted with a Limited Slip Differential (LSD) as standard. They were also available with Mercedes' ASD system which was standard equipment on the 2.5-16v. The ASD is an electronically controlled, hydraulically locking differential which activates automatically when required. The electronic control allows varied amounts of differential lock from the standard 15% right up to 100%. It is not a traction control system however, and can only maximize traction rather than prevent wheel spin. Activation of the ASD system is indicated by an illuminating amber triangle in the speedometer.
The suspension on 16-valve models is very different from the standard 190 (W201). As well as being lower and stiffer, it has quicker dampers, larger anti-roll bars, harder bushings and hydraulic Self-levelling suspension (SLS) on the rear. This allows the rear ride height to remain constant even when the car is fully loaded.
At the inauguration of the new, shorter Nürburgring in 1984, a race with identical cars was held, with former and current F1 pilots at the wheel. A then unknown Ayrton Senna took first place.
Private Teams such as AMG later entered the 2.3-16 in touring cars races, especially the DTM. In the late 1980s, the 2.5-16 (never released in the United States) raced many times, against the similar BMW M3 and even the turbocharged Ford Sierra RS Cosworth.

Mittelenglisch nennt man die Form der englischen Sprache, die etwa zwischen dem 12. und der Mitte des 15. Jahrhunderts gesprochen wurde.

Sie teilen dieselbe bio-georaphische Klimaregion: Atlanisch.
Biogeographic Region: Atlantic
-
Das Altenglische entstand, als die Angeln, Jüten, Friesen und Sachsen sich ab ca. 450 in Britannien ansiedelten.
Altenglisch wurde ursprünglich mit Runen geschrieben, übernahm nach der Bekehrung zum Christentum jedoch das lateinische Alphabet, dem man einige Zeichen hinzufügte. So etwa wurde der Buchstabe Yogh aus dem Irischen übernommen, der Buchstabe ð (eth) war eine Abwandlung des lateinischen d, und die Buchstaben þ (thorn) und ƿ (wynn) stammen aus dem Fuþorc (der anglo-friesischen Variante der gemeingermanischen Runenreihe, dem älteren Fuþark).
Für Sprecher des modernen Englisch ist diese Sprachstufe ohne gezieltes Erlernen nicht mehr verständlich. Sie ist eine eng mit dem Friesischen und Niederdeutschen verwandte westgermanische Sprache und gehört der Gruppe der germanischen Sprachen an, einem Hauptzweig der indoeuropäischen Sprachfamilie.
Die angelsächsische Sprache spaltete sich ab dem 5. Jahrhundert vom kontinentalen Westgermanisch ab, als die Angeln, Sachsen, Friesen und Jüten sich in Britannien ansiedelten (Schlacht von Mons Badonicus). Vom 8. Jahrhundert an ist sie schriftlich belegt und erreicht um 1000 ein hohes Maß an Standardisierung (Spätwestsächsisch der „Schule von Winchester“).
Aus den vorher auf der Insel gesprochenen keltischen Sprachen übernahm das Angelsächsische nur sehr wenige Lehnwörter.
...
Durch die dänische und norwegische Einwanderung ab dem 8. Jahrhundert hat die englische Sprache gegenüber der altsächsischen Sprache auch zahlreiche nordgermanische Elemente integriert, die allerdings erst in den mittelenglischen Texten in größerer Zahl auftauchen, darunter neben einigen hundert anderen Wörtern so zentrale Begriffe wie sky, leg und das moderne Pronomen they.
Stärker noch als in der niedersächsischen Sprache wurden auch Elemente der lateinischen Sprache aufgenommen, insbesondere im Bereich des religiösen Wortschatzes.
Die Dialektsprecher auf dem Festland und der Insel konnten sich miteinander verständigen.
Einschnitt:
Mit der Eroberung Englands durch die französischen Normannen 1066
wurde die Sprache durch den französischen Einfluss aus der Normandie so sehr verändert, dass man sie ab diesem Zeitpunkt als mittelenglische Sprache bezeichnet.
...
Thema - you - they.
Um mehr zu sagen, ist die etymologische Seite dieses "Problems" sehr erhellend: Früher im Altenglischen war das ursprüngliche Wort für "Du" - "thou" - man findet es noch in alten sakralen Texten und Liedern. Und Ihr hieß ye- ye bezog sich also auf mehr als einen Anzuredenden.
Dann nach der normannischen Eroberung fand ein Einzug französischer Sprachelemente ins Englische statt, dies nennt sich Mittelenglische Zeit. "Thou" wurde langsam ersetzt durch "ye" da die französisch-höfische Sitte den Plural vorschrieb, um eine höherstehende Person anzusprechen, dies übertrug sich später auf gleichgestellte Personen.
Jedoch verblieb "thou" noch lange Zeit im Sprachgebrauch. Die Unterscheidung zwischen formaler und nicht-formaler Anrede kam von der üblich Anrede von Königen und anderen höfischen Adelspersonen im Plural. Das wurde schließlich weiter ausgedehnt, um jedwede höhergestellte Person oder Unbekannte mit dem Pluralwort "ye" anzureden. Denn dies wurde als höf-licher ! empfunden.
Das französische "tu" wurde als ein sehr intimes oder herablassendes Anredewort empfunden, einem Fremden gegenüber insbesondere als beleidigend. Im 18. Jahrhundert schrieb Samuel Johnson (ein sehr einflußreicher Gelehrter seiner Zeit, Autor, Essayist, Kritiker, Verfasser des ersten maßgeblichen Lexikons der Englischen Sprache) in seinem Werk: A Grammar of the English Tongue: "im zeremoniellen Sprachgebrauch..wird die zweite Person Plural für die zweite Person Singular verwendet..". Vergleichsweise schreibt The Merriam Webster Dictionary of English Usage, dass um 1650 herum bei den meisten Sprechern des südbritannischen Englisch "thou" unüblich geworden war, sogar im informalen Sprachgebrauch unter Freunden nicht mehr verwendet wurde.
Also wir erkennen: Das Wörtchen "thou" war veraltet, und das "ye" hat sich einfach als das gebräuchlichere Wort für "du", also die 2. Person Singular, eingeschlichen gehabt, weil man wohl zum einen sich dem Adel dadurch näher fühlte, also sich sozial aufgewertet sah, und die Gefahr, unhöflich zu sein, verringert wurde. Interessantes
Nebendetail:
auch heute gibt es in England noch einen Ort , wo das "thou" noch lebt im Sprachgebrauch:Lichfield, Staffordshire, wo Dr. Samuel Johnson geboren wurde. Und natürlich richtet sich das Verb nach dem Mehrzahlpronomen "ye", das "ye" das zum heutigen "you" verschmolzen ist!

Fangruida: human landing on Mars 10 cutting-edge technology
[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]
Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project
-------------------------------------------------- -------------
Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.
Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.
1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.
Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant
High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.
Nuclear-powered spaceship for Use of nuclear power are three kinds:
The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.
The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,
Plasma Engine
Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "
The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.
Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.
Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.
3, high-performance nuclear rocket
Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.
Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works.
Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust.
A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.
Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction.
Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.
Of course there are various research and development of rocket technology and technical solutions to try.
It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.
Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

3. For the purposes of this principle, compensation should be made to include reimbursement of the duly substantiated expenses for search, recovery and clean
Cost management work, including the cost of providing assistance to third parties.
10. The principle of dispute settlement
Since the implementation of these principles will lead to any dispute in accordance with the provisions of the UN Charter, by negotiation or
Other established procedures to resolve the peaceful settlement of disputes.
Here quoted the important provisions of the United Nations concerning the use of outer space for peaceful nuclear research and international conventions, the main emphasis on the Peaceful Uses of provisions related constraints .2 the use of nuclear rockets in outer space nuclear studies, etc., can cause greater attention in nuclear power nuclear rocket ship nuclear research, manufacture, use and other aspects of the mandatory hard indicators. this scientists, engineering and technical experts are also important constraints and requirements. as IAEA supervision and management as very important.
2. radiation. Space radiation is one of the greatest threats to the safety of the astronauts, including X-rays, γ-rays, cosmic rays and high-speed solar particles. Better than aluminum protective effect of high polymer composite materials.
3. Air. Perhaps the oxygen needed to rely on oxidation-reduction reaction of hydrogen and ilmenite production of water, followed by water electrolysis to generate oxygen. Mars oxygen necessary for survival but also from the decomposition of water, electrolytically separating water molecules of oxygen and hydrogen, this oxygen equipment has been successfully used in the International Space Station. Oxygen is released into the air to sustain life, the hydrogen system into the water system.
4. The issue of food waste recycling. At present, the International Space Station on the use of dehumidifiers, sucked moisture in the air to be purified, and then changed back to drinkable water. The astronauts' urine and sweat recycling. 5. water. The spacecraft and the space station on purification system also makes urine and other liquids can be purified utilization. 6. microgravity. In microgravity or weightlessness long-term space travel, if protective measures shall not be treated, the astronauts will be muscle atrophy, bone softening health. 7. contact. 8. Insulation, 9 energy. Any space exploration are inseparable from the energy battery is a new super hybrid energy storage device, the asymmetric lead-acid batteries and supercapacitors in the same compound within the system - and the so-called inside, no additional separate electronic control unit, this is an optimal combination. The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.
Plantar molt
After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space
Bone and muscle loss
Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.
Space Blindness
Space Blindness refers astronaut decreased vision.
Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.
Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.

With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.
Space sickness
In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.
Robot surgeons
Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.
Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.
Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.
These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant.

High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.
Fuel storage
In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.
This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.
Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.
When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards
Mars
Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.
Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.
Super rigid parachute to help slow the landing vehicle.
Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very
Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.
In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.
The moon is sterile. Mars is another case entirely.

Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.
Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.
*** Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.
Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

The outermost layer of the crust.
Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.
Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.
In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.
Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core
The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].
Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.
Lunar landscape
Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.
Regolith
TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.
Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology
Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project
[
"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.
In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.
In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.
Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.
Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.
.
After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.
Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.
The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.
Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.
Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.
Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.
Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown
Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.
Water quality monitoring sampling system:
Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.
Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.
Equipment cooling water system:
Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.
Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.
Safety Injection System: The main components of this system is the high-pressure injection pump.
Radioactive waste treatment systems:
Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.
Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

The design of the BMW i8 coupe prototype was based on the BMW i8 Concept. The BMW i8 prototype has an average fuel efficiency of less than 2.5 L/100 km (113.0 mpg-imp; 94.1 mpg-US) under the New European Driving Cycle with carbon emissions of less than 59 g/km. The i8 with its carbon-fiber-reinforced plastic (CFRP) passenger cell lightweight, aerodynamically optimized body, and BMW eDrive technology offers the dynamic performance of a sports car, with an expected 0–100 km (0–60 mi) sprint time of less than 4.5 seconds using both power sources. The plug-in hybrid system of the BMW i8 comprises a three-cylinder, 1.5-liter BMW TwinPower turbo gasoline engine combined with BMW eDrive technology used in the BMW i3 and develops maximum power of 170 kW (230 hp). The BMW i8 is the first BMW production model to be powered by a three-cylinder gasoline engine and the resulting specific output of 115 kW (154 hp) per liter of displacement is on a par with high-performance sports car engines and is the highest of any engine produced by the BMW Group.
The BMW i8's second power source is a hybrid synchronous electric motor specially developed and produced by the BMW Group for BMW i. The electric motor develops maximum power of 131 hp (96 kW) and produces its maximum torque of around 320 N·m (240 lbf·ft) from standstill. Typical of an electric motor, responsive power is instantly available when starting and this continues into the higher load ranges. As well as providing a power boost to assist the gasoline engine during acceleration, the electric motor can also power the vehicle by itself. Top speed in electric mode is approximately 120 km/h (75 mph), with a maximum driving range of up to 35 km (22 mi). Linear acceleration is maintained even at higher speeds since the interplay between the two power sources efficiently absorbs any power flow interruptions when shifting gears. The BMW i8 has an electronically controlled top speed of 250 km (160 mi), which can be reached and maintained when the vehicle operates solely on the gasoline engine. The model-specific version of the high-voltage 7.2 lithium-ion battery has a liquid cooling system and can be recharged at a conventional household power socket, at a BMW i Wallbox or at a public charging station. In the US a full recharge takes approximately 3.5 hours from a conventional 120V, 12 amp household circuit or approximately 1.5 hours from a 220V Level 2 charger.
The driver can also select several driving modes: SPORT, COMFORT and ECO PRO. Using the gear selector, the driver can either select position D for automated gear selection or can switch to SPORT mode. SPORT mode offers manual gear selection and at the same time switches to very sporty drive and suspension settings. In SPORT mode, the engine and electric motor deliver extra performance, accelerator response is faster and the power boost from the electric motor is maximized. And to keep the battery topped up, SPORT mode also activates maximum energy recuperation during overrun and braking as the electric motor’s generator function, which recharges the battery using kinetic energy, switches to a more powerful setting. The Driving Experience Control switch on the center console offers a choice of two settings. On starting, COMFORT mode is activated, which offers a balance between sporty performance and fuel efficiency, with unrestricted access to all convenience functions. Alternatively, the ECO PRO mode can be engaged, which, on the BMW i8 as on other models, supports an efficiency-optimized driving style. On this mode the powertrain controller coordinates the cooperation between the gasoline engine and the electric motor for maximum fuel economy. On deceleration, the intelligent energy management system automatically decides, in line with the driving situation and vehicle status, whether to recuperate braking energy or to coast with the powertrain disengaged. At the same time, ECO PRO mode also programs electrical convenience functions such as the air conditioning, seat heating and heated mirrors to operate at minimum power consumption, but without compromising safety. The maximum driving range of the BMW i8 on a full fuel tank and with a fully charged battery is more than 500 km (310 mi) in COMFORT mode, which can be increased by up to 20% in ECO PRO mode. The BMW i8’s ECO PRO mode can also be used during all-electric operation. The vehicle is then powered solely by the electric motor. Only if the battery charge drops below a given level, or under sudden intense throttle application such as kickdown, is the internal combustion engine automatically activated.
The vehicle was unveiled in BMW Group's Miramas test track in France.
Production version
The production BMW i8 was designed by Benoit Jacob. The production version was unveiled at the 2013 International Motor Show Germany, followed by 2013 Les Voiles de Saint-Tropez. It features butterfly doors, head-up display, rear-view cameras and partially false engine noise. Series production of customer vehicles began in April 2014. It is the first production car with laser headlights, reaching further than LED lights.
The i8 has a low vehicle weight of 1,485 kg (3,274 lb) (DIN kerb weight) and a low drag coefficient (Cd) of 0.26. In all-electric mode the BMW i8 has a top speed of 120 km/h (75 mph). In Sport mode the i8 delivers a mid-range acceleration from 80 to 120 km/h (50 to 75 mph) in 2.6 seconds. The electronically controlled top speed is 250 km/h (160 mph).
Range and fuel economy[edit]
The production i8 has a 7.1 kWh lithium-ion battery pack with a usable capacity of 5.2 kWh and intelligent energy management that delivers an all-electric range of 37 km (23 mi) under the NEDC cycle. Under the EPA cycle, the range in EV mode is 15 mi (24 km), with a gasoline consumption of 0.1 gallons per 100 mi, and as a result, EPA's all-electric range is zero. The total range is 330 mi (530 km).
The production version has a fuel efficiency of 2.1 L/100 km (134.5 mpg-imp; 112.0 mpg-US) under the NEDC test with carbon emissions of 49 g/km.[5] Under EPA cycle, the i8 combined fuel economy in EV mode was rated 76 equivalent (MPG-equivalent) (3.1 L gasoline equivalent/100 km; 91 mpg-imp gasoline equivalent), with an energy consumption of 43 kW-hrs/100 mi and gasoline consumption of 0.1 gal-US/100 mi. The combined fuel economy when running only with gasoline is 28 mpg-US (8.4 L/100 km; 34 mpg-imp), 28 mpg-US (8.4 L/100 km; 34 mpg-imp) for city driving, and 29 mpg-US (8.1 L/100 km; 35 mpg-imp) in highway.
The U.S. Environmental Protection Agency's 2014 edition of the "Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends" introduced utility factors for plug-in hybrids to represent the percentage of miles that will be driven using electricity by an average driver, in electric only or blended modes. The BMW i8 has a utility factor in EV mode of 37%, compared with 83% for the BMW i3 REx, 66% for the Chevrolet Volt, 65% for the Cadillac ELR, 45% for the Ford Energi models, 43% for the McLaren P1, 39% for the Porsche Panamera S E-Hybrid, and 29% for the Toyota Prius PHV.

I am working on several books on "epic photography," and I recently finished a related one titled: The Golden Number Ratio Principle: Why the Fibonacci Numbers Exalt Beauty and How to Create PHI Compositions in Art, Design, & Photography: An Artistic and Scientific Introduction to the Golden Mean . Message me on facebook for a free review copy!

The Golden Ratio informs a lot of my art and photographic composition. The Golden Ratio also informs the design of the golden revolver on all the swimsuits and lingerie, as well as the 45surf logo! Not so long ago, I came up with the Golden Ratio Principle which describes why The Golden Ratio is so beautiful.
The Golden Number Ratio Principle: Dr. E’s Golden Ratio Principle: The golden ratio exalts beauty because the number is a characteristic of the mathematically and physically most efficient manners of growth and distribution, on both evolutionary and purely physical levels. The golden ratio ensures that the proportions and structure of that which came before provide the proportions and structure of that which comes after. Robust, ordered growth is naturally associated with health and beauty, and thus we evolved to perceive the golden ratio harmonies as inherently beautiful, as we saw and felt their presence in all vital growth and life—in the salient features and proportions of humans and nature alike, from the distribution of our facial features and bones to the arrangements of petals, leaves, and sunflowers seeds. As ratios between Fibonacci Numbers offer the closest whole-number approximations to the golden ratio, and as seeds, cells, leaves, bones, and other physical entities appear in whole numbers, the Fibonacci Numbers oft appear in nature’s elements as “growth’s numbers.” From the dawn of time, humanity sought to salute their gods in art and temples exalting the same proportion by which all their vital sustenance and they themselves had been created—the golden ratio.

Transportes Generales Comes acaba de incorporar cuatro unidades de Irizar i6 Efficient con chasis Volvo B13R.
Estas unidades, numeradas del 611 al 614, acaban de ser matriculadas, y en el día de ayer, el 611 hizo su primera salida, estrenándose en la línea Cádiz-Algeciras-Málaga.
Estos Irizar i6 vienen a reforzar la flota de la empresa gaditana, y a sustituir a los veteranos Irizar Century III Volvo B12B, de la serie 499-510, que con sus 18 años de antiguedad, todavía están rodando (salvo cuatro unidades), con total solvencia.
Cuentan con el motor B13R de Volvo, de 430 cv de potencia, y disponen de una longitud de 13.35 metros.
Como novedad, cuentan con display electrónico lateral y trasero (además del frontal), algo que solía estar destinado solo a las unidades de cercanías.
Además son los primeros coches de largo recorrido que estrenan el nuevo logo de la empresa, además del TPA de la Junta (aunque como detalle, la culera no debería estar en verde Junta de Andalucía, sólo el tercio lateral, ya que ese esquema sólo está destinado para los coches del Consorcio de Transportes).
Vemos al 612 el 8 de Julio de 2024, entrando en Chiclana procedente de La Línea y dirección Sevilla.

Due to the higher energy usage of incandescent light bulbs in comparison to more energy efficient alternatives, like compact fluorescent lamps and LED lamps, some governments have passed laws and regulations that have started to phase out their usage.
Brazil and Venezuela started to phase them out in 2005, and other nations are planning scheduled phase-outs: Ireland in 2009, Australia in 2010, Canada in 2012, and the U.S. between 2012 and 2014.
Most of these laws and regulations do not ban the usage of incandescents, but rather ban their sale.
SAVE THE BULB !! :p
On a lighter note...................
Q: How many Psychiatrists does it take to change a lightbulb?
A: Only one, but the bulb has got to really WANT to change.
Q: How many programmers does it take to screw in a lightbulb?
A: None. That's a hardware problem.
Q: How many `Real Men' does it take to change a lightbulb?
A: None: `Real Men' aren't afraid of the dark.
Q: How many `Real Women' does it take to change a lightbulb?
A: None: A 'Real Woman' would have plenty of real men around to do it.
Q: How many folk singers does it take to screw in a lightbulb?
A: Two. One to change the bulb, and one to write a song about how good the old lightbulb was.
Q: How many lawyers does it take to change a lightbulb?
A: How many can you afford?
Q: How many mystery writers does it take to screw in a lightbulb?
A: Two, one to screw it almost all the way in and the other to give it a surprising twist at the end.
Q: How many existentialists does it take to screw in a lightbulb?
A: Two: One to screw it in and one to observe how the lightbulb itself symbolizes a single incandescent beacon of subjective reality in a netherworld of endless absurdity reaching out toward a maudlin cosmos of nothingness.
"Black bears are efficient berry-eaters, consuming up to 30,000 berries a day in a good year. They gather berries quickly, using their sensitive, mobile lips and swallowing them whole. The berries enter a two-part stomach, which grinds the pulp off the seeds. The seeds pass through the digestive tract unbroken and able to germinate, making black bears important seed dispersers. Each summer, they spread the seeds of their favorite berries all over their home ranges."
www.bear.org/website/bear-pages/black-bear/foraging-a-foo...
"Black bears are omnivorous animals, but mostly eat vegetation and fruits. Despite their tough appearance and long teeth and claws, 85% of a black bear's diet comes from plants. They also like to eat honey and can rip open a whole tree to get into a beehive. Black bears' thick coats protect them from stinging bees, meaning they can eat the honeycombs as fast or as slowly as they like. At night, black bears in the Pacific Northwest fish for salmon in rivers. A few enterprising bears also venture into human-populated areas to steal from trashcans or campsites. In the fall, when they are preparing for hibernation, black bears eat lots of bugs like ants and bees for their protein. Black bears also sometimes catch baby deer, cows and moose, but they are more likely to try to steal carcasses from more active predators like wolves, coyotes and cougars. The extra proteins help them gain fat for their long, annual hibernation." From www.whatdobearseat
Yesterday, 5 September 2019, friend Pam and I had a great day out in Kananaskis. It had been just over two months since I drove myself out there, but Pam had been only two days ago. There were a few different places that she wanted to stop yesterday, and she was hoping to see a bear - preferably a Grizzly, but we were out of luck for that. However, we were lucky enough to see two Black Bears, which was such a treat.
Our day started off really well, leaving the city at 7:00 am. Driving along a backroad SW of the city, a small, rather cute, old barn was our first find. It was set back from the road and easily missed, so I'm glad I spotted it.
Further on, we came across a White-tailed Deer feeding in a field, and it looked so beautiful in the early morning sun. Normally, I don't get out this early and I know I miss that special light.
Going to have to finish description, etc. later ....

The Toyota Mirai , Japanese for "future") is a hydrogen fuel cell vehicle manufactured by Toyota, one of the first such vehicles to be sold commercially. The Mirai was unveiled at the November 2014 Los Angeles Auto Show. As of December 2017, global sales totaled 5,300 Mirais. The top selling markets were the U.S. with 2,900 units, Japan with 2,100 and Europe with 200.
Under the United States Environmental Protection Agency (EPA) cycle, the 2016 model year Mirai has a total range of 502 km (312 mi) on a full tank, with a combined city/highway fuel economy rating of 66 mpg‑US (3.6 L/100 km; 79 mpg‑imp) equivalent (MPG-equivalent), making the Mirai the most fuel efficient hydrogen fuel cell vehicle rated by the EPA, and the one with the largest range.
Cascade Heights, Burnaby, British Columbia
In 2004, Rafael Viñoly Architects designed 20 Fenchurch Street, a high-performance, energy-efficient building to replace an obsolete office tower in the heart of the City of London. The design breaks with common architectural expression by enlarging the floor plans at the top of the building instead of the bottom, creating additional public space at ground level and providing extra leasable floor area to the valuable upper stories.
20 Fenchurch Street is also uniquely crowned by a three-level Sky Garden, London’s first publicly accessible tall building observation deck, featuring 360-degree views of the city, beautifully landscaped gardens, an open air terrace, two restaurants and the ability to host a variety of functions.
The tower, comprising thirty-two levels of Grade A office space and a double height ground-floor lobby, ascends to a height of 176.66 m (579 ft.). The building’s profile rises from a narrow base to a wide, curved roof, making it a distinctive addition to London’s skyline, while the curved floor plates reference the plot site boundaries and adjacent street patterns.
Vertical louvers on the building’s façade provide sun shading on the east and west elevations, which follow the fanning form and organic curves of the building as they open out and wrap over the roof and Sky Garden. The north and south elevations feature extensive glazing to maximize views, while the curtain wall on the upper floors of the north façade extends to the roof louvers arched above, providing a large urban window spanning the full height of the Sky Garden.
At ground level, the narrowed base creates open landscaped plazas and pedestrian paths through the site, including a pocket park that connects Rood Lane and Philpot Lane. The development also includes a separate five-storey Annex Building to the south of the site, housing retail space that draws visitors to the plaza and enlivens the space.
The building has been designed to offer maximum efficiency and flexibility for potential tenants, with all office floors and services capable of being sub-divided into independent tenancies. The building is also targeting a BREEAM Excellent rating with the incorporation of sustainable technology including PV cells and a fuel cell tri-generation system designed to reduce CO2 emissions.
Due for completion in early 2014, this innovative project will combine public and private spaces, offering businesses and public visitors alike, the opportunity to experience stunning views of London and embrace 20 Fenchurch Street as a new landmark for the capital.

In 1982 Mercedes-Benz released the production version of more than a decade's research into developing a compact format, efficient and safe luxury car. The name '190' referred back to the 1950 and 60s versions of 'reduced power output' models of their mainstream saloon car range. The 190E specified a fuel-injected 2.0 litre, four cylinder engine, whilst a 190 model, without the 'E' (for einspritz' appellation, referred to the same engine, but using a carburetor.
This is the version most commonly seen in taxis, along with a 2.0 litre 4-cylinder diesel, with even less power......
Then something strange happened within the halls of Mercedes-Benz....
190E 2.3-16 & 2.5-16 "Cosworth":
In the late 1970s, Mercedes competed in rallying with the big V8-powered Coupés of the R107 Series, mainly the light-weight Mercedes 450 SLC 5.0. Mercedes wished to take the 190 E rallying, and asked British engineering company Cosworth to develop an engine with 320 bhp (239 kW) for the rally car. This project was known as project "WAA' by Cosworth". During this time, the Audi Quattro with its all-wheel drive and turbocharger was launched, making the 2.3-16v appear outclassed. With a continued desire to compete in high-profile motor sport with the 190, and also now an engine to do it with, Mercedes turned to the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) motor sport series instead. Cars racing in this championship, however, had to be based on a roadgoing model. Mercedes therefore had to put into series production a 190 fitted with a detuned version of the Cosworth engine. This high-performance model was known as the 190 E 2.3-16, and debuted at the Frankfurt Auto Show in September 1983, after its reputation had already been established. Three cars, only slightly cosmetically altered, had set three world records in August at the Nardo testing facility in Italy, recording a combined average speed of 154.06 mph (247.94 km/h) over the 50,000 km endurance test, and establishing twelve international endurance records. The Mercedes 190-E Cosworth was also featured on the second episode in series fifteen of the popular car show Top Gear.
Engin:
2.5-16 Cosworth
The Cosworth engine was based on the M102 four cylinder 2.3-litre 8-valve 136 hp (101 kW) unit already fitted to the 190- and E-Class series. Cosworth developed the cylinder head, "applying knowledge we've learnt from the DFV and BDA." It was made from light alloy using Coscast's unique casting process and brought with it dual overhead camshafts and four valves per cylinder, meaning 16 valves total which were developed to be the "largest that could practically be fitted into the combustion chamber".
In roadgoing trim,the 2.3 L 16-valve engine made "185 hp (138 kW) at 6,200 rpm and 174 lb·ft (236 N·m) at 4,500 rpm. The oversquare 95.50 x 80.25 mm bore and stroke dimensions ensuring that it revs easily up to the 7000 rpm redline". Acceleration from 0–100 km/h (62 mph) was less than eight seconds, and the top speed was 230 km/h (143 mph).
US-Specification cars had a slightly reduced compression ratio (9.7:1 instead of 10.5:1), and were rated at 167 hp (125 kW) @ 5800 rpm and 162 lb·ft (220 N·m) @ 4750.
The roadgoing version of the engine was reconfigured with reduced inlet and exhaust port sizes, different camshaft profiles, no dry sump configuration and Bosch K-jetronic replacing the specialised Kugelfischer fuel injection. These changes helped bring power down to the required 185 bhp (138 kW) specification, but still resulted in a "remarkably flexible engine, with a very flat torque curve and a wide power band". The heads for the engines were cast at Cosworth's Coscast foundry in Worcester and sent to Germany to be fitted to the rest of the engine, parts of which were different from the standard 2.3 including light pressed alloy pistons, and rings designed to withstand higher engine speeds, whilst con-rods, bearings and bearing caps were found to be strong enough as standard and left unaltered.
16v differences:
Due to their performance, the 16-valve cars were different from the other 190 models. The body kit on the 2.3-16 and 2.5-16 reduced the drag coefficient to 0.32, one of the lowest CD values on a four-door saloon of the time, whilst also reducing lift at speed. The steering ratio was quicker and the steering wheel smaller than that on other 190s, whilst the fuel tank was enlarged from 55 to 70 L. The Getrag 5-speed manual gearbox was unique to the 16-valve and featured a 'racing' gear pattern with 'dog-leg' first gear, left and down from neutral. This meant that the remaining 2nd, 3rd, 4th and 5th gears were in a simple H pattern allowing fast and easy selection. The gearchange quality was, however, noted as "notchy, baulky", criticisms which weren't levelled at the BMW M3 (E30) which shared the same gearbox. The pattern is also unusual in that the driver engages reverse by shifting left and up from neutral, as for first gear in a conventional pattern. This was demonstrated in a Top Gear episode (S15E02) where James May took a 190E 2.3-16 Cosworth and repeatedly confused reverse and first gear. An oil cooler was fitted to ensure sufficient oil cooling for the inevitable track use many of these cars were destined for.
The strictly four-seater interior had Recaro sports seats with strong side bolsters for front and rear passengers. 3 extra dials - an oil temperature gauge, stopwatch and voltmeter - were included in the centre console. The 190 E 2.3-16 was available in only two colours, Blue-Black metallic (Pearl Black in the US), and Smoke Silver. The 2.5-16 added Almandine Red and Astral Silver.
All 2.3-16-valve 190 models are fitted with a Limited Slip Differential (LSD) as standard. They were also available with Mercedes' ASD system which was standard equipment on the 2.5-16v. The ASD is an electronically controlled, hydraulically locking differential which activates automatically when required. The electronic control allows varied amounts of differential lock from the standard 15% right up to 100%. It is not a traction control system however, and can only maximize traction rather than prevent wheel spin. Activation of the ASD system is indicated by an illuminating amber triangle in the speedometer.
The suspension on 16-valve models is very different from the standard 190 (W201). As well as being lower and stiffer, it has quicker dampers, larger anti-roll bars, harder bushings and hydraulic Self-levelling suspension (SLS) on the rear. This allows the rear ride height to remain constant even when the car is fully loaded.
At the inauguration of the new, shorter Nürburgring in 1984, a race with identical cars was held, with former and current F1 pilots at the wheel. A then unknown Ayrton Senna took first place.
Private Teams such as AMG later entered the 2.3-16 in touring cars races, especially the DTM. In the late 1980s, the 2.5-16 (never released in the United States) raced many times, against the similar BMW M3 and even the turbocharged Ford Sierra RS Cosworth.
Evolution models:
2.5-16 Evolution II
With the debut of the BMW M3 Sport Evolution, Mercedes' direct competitor, it became obvious that the 2.5-16 needed a boost for the circuit. In March 1989, the 190 E 2.5-16 Evolution debuted at the Geneva Auto Show. The Evo I, as it came to be called, had a new spoiler and wider wheel arches. Many changes were made to under-the-skin components such as brakes and suspension. There was a full SLS suspension allowing vehicle ride height to be adjusted from an interior switch. All were intended to allow the Evolution cars to be even more effective round a track.
The Evo I's output is similar to the 202 bhp (151 kW) of the "regular" 2.5-16. However this car had a redesigned engine of similar capacity but, most importantly, a shorter stroke and bigger bore which would allow for a higher rev limit and improved top-end power capabilities. Additional changes stretch to "rotating masses lightened, lubrication improved and cam timing altered". Cosworth also list a project code "WAC" for the development of the short-stroke Evolution engine.
Only 502 units of the Evolution model were produced for homologation in compliance with DTM rules. For those customers desiring even more performance, a PowerPack option engineered by AMG was available for DM 18,000. The PowerPack option included hotter camshafts, a larger diameter throttle body, more aggressive ignition and fuel management as well as optimization of the intake and exhaust systems. The net result was an additional 30 bhp (22 kW).
In March 1990, at the Geneva Auto Show, the 190 E 2.5-16 Evolution II was shown. With the success of the first Evolution model, this model's 502-unit production was already sold before it was unveiled.
The "Evo II" included the AMG PowerPack fitted to the same short-stroke 2.5 engine as the Evolution, as well as a full SLS suspension allowing vehicle ride height to be adjusted from an interior switch. An obvious modification to the Evolution II is a radical body kit (designed by Prof. Richard Eppler from the University of Stuttgart) with a large adjustable rear wing, rear window spoiler, and Evolution II 17-inch wheels. The kit served an aerodynamic purpose — it was wind tunnel tested to reduce drag to 0.29, while at the same time increasing downforce. Period anecdotes tell of a BMW executive who was quoted as saying "if that rear wing works, we'll have to redesign our wind tunnel." The anecdote claims that BMW did.
As mentioned 500 were made in "blauschwarz" blue/black metallic. But the last two, numbers 501 and 502 were made in astral silver.

Eleven supremely fit and ruthlessly efficient cricketers, on top of their game, had their dreams of a first-ever world title ended by one audacious man. That cricket is a team game is an oft repeated cliché but South Africa were eliminated from the World Twenty20 at Trent Bridge solely because of Shahid Afridi's intensity and all-round skill.
Pakistan were yet to win a game against significant opposition in the tournament because of a team performance. They lost to England and Sri Lanka, beat minnows Netherlands and Ireland, and relied on Umar Gul to rout New Zealand. Their players hadn't contributed collectively and so it was unlikely all 11 players would maximise potential against opponents as able as South Africa. To have a hope of playing at Lord's on Sunday, Pakistan needed individual brilliance from one of their matchwinners: probably Gul, possibly Younis Khan, or perhaps Misbah-ul-Haq.
Instead, it came from Afridi. Pakistan and Afridi supporters always hope that it will come from him. They roar him to the crease, brimming with optimism, hoping he will destroy the opposition with his recklessly cavalier approach. Thousands of fans celebrated his arrival at the crease at Trent Bridge after Pakistan had lost Shahzaib Hasan in the second over.
Did they know that Afridi's last half-century, in any format of the game, came 28 innings ago, against Zimbabwe at Multan in 2008? And the one before that was 19 innings earlier, against Sri Lanka in Abu Dhabi in 2007? It didn't matter, for when it comes to Afridi, there's always reason to hope. He'll disappoint more often than not, but his successes are so spectacular that it's worth the heartbreaks.
Afridi batted at No. 6 during the initial stages of the World Twenty20 and having to necessarily find the boundary immediately didn't work for him. He made 5 against England, holing out to mid-on, was bowled for 13 by Dirk Nannes against Netherlands, and was dismissed for a first-ball duck against Sri Lanka. Pakistan decided to push him up to No. 5 against New Zealand and he made 29 low-pressure runs off 18 balls, and 24 off 13 balls at No 3 against Ireland. Afridi said Younis supported him fully, put no pressure on him, and asked him to bat higher in the order, only requesting that he take his time and not attempt impractical risks like trying to pull Muttiah Muralitharan into orbit off his first delivery.
On first evidence at Trent Bridge, Afridi appeared not to heed that request, whacking his first ball, from Wayne Parnell, over mid-on for four. He was bristling with aggression when Jacques Kallis tested his skill against the short ball. Afridi was beaten by the first couple but pulled two out of the following three to the midwicket boundary. Kallis walked up to him and stared and Afridi's response was an attempt to get under the skin of the bowler. "He [Kallis] came close to me, I gave him a kiss," Afridi said. "A flying kiss."
Afridi's posture had betrayed disappointment when Kamran Akmal fell off his 12th ball, having scored 23 off the first 11, by top-edging a pull to mid-on. Afridi had also started quickly, scoring 15 off nine, but wasn't about to go the Akmal way. No risks were taken immediately after the fielding restrictions were lifted, Afridi being content with working the ball cleverly into gaps to score at a run a ball.
Not until the 11th over did he cut loose, against Johan Botha, and his execution was precise. Three times in a row Afridi made room by moving towards leg, and all three times he placed the ball into the gap on the extra cover boundary. And when Graeme Smith reinforced his field, Afridi played the deftest of late cuts to take 18 off the over. His first moment of indiscretion was also his last for an ill-timed swipe across the line against JP Duminy's first ball went straight in the air. Trent Bridge reverberated with applause as Afridi returned to the dugout, having scored 51 off 34 balls. And he was only half done.
While Afridi's batting deteriorated over the last couple of years, his bowling has been vital to Pakistan's limited-over success. He even said on Cricinfo that he rates himself as a bowler first. So unlike his batting, Afridi's legspin was in top form during the World Twenty20 with eight wickets and an economy of less than six an over, going into the game against South Africa.
Bouyed by his batting, Afridi's high intensity levels kept him in the thick of the action. He appeared stunned after Gul dropped Smith and hit his head on the ground, standing motionless for a few moments before realising the ball needed to be collected, and then attended to his injured team-mate. He was given the ball in the seventh over and found rhythm immediately, getting one to turn, bounce and rip past Kallis' bat. Gibbs watched that from the non-striker's end and so pushed forward, playing away from his body for the legbreak, a ball later. It didn't turn. Instead it fizzed off the pitch and skidded straight through, knocking back off stump.
Afridi had an edge put down by Kamran Akmal off AB de Villiers in his next over. Unfazed, he forced the batsmen to play on the next ball, and celebrated in trademark style: running to the side of the pitch, standing upright with his chest proudly out, a knowing grin in his face and his left hand raised in triumph while his team-mates rushed in from all corners of the outfield. As they mobbed him, the DJ got the crowd going by playing Dil Dil Pakistan.
Afridi finished with 2 for 16 to go with his half-century. After he was done, Saeed Ajmal dismissed Kallis, Gul bowled a succession of yorkers, and Mohammad Aamer kept his cool when entrusted with the final over. There was no doubt, though, why Pakistan had won. It was obvious from the number of times Smith mentioned Afridi's name during the post-match press conference without even being specifically asked.

Some background:
Simple, efficient and reliable, the Regult (リガード, Rigādo) was the standard mass production mecha of the Zentraedi forces. Produced by Esbeliben at the 4.432.369th Zentraedi Fully Automated Weaponry Development and Production Factory Satellite in staggering numbers to fill the need for an all-purpose mecha, this battle pod accommodated a single Zentraedi soldier in a compact cockpit and was capable of operating in space or on a planet's surface. The Regult saw much use during Space War I in repeated engagements against the forces of the SDF-1 Macross and the U.N. Spacy, but its lack of versatility against superior mecha often resulted in average effectiveness and heavy losses. The vehicle was regarded as expendable and was therefore cheap, simple, but also very effective when fielded in large numbers. Possessing minimal defensive features, the Regult was a simple weapon that performed best in large numbers and when supported by other mecha such as Gnerl Fighter Pods. Total production is said to have exceeded 300 million in total.
The cockpit could be accesses through a hatch on the back of the Regult’s body, which was, however, extremely cramped, with poor habitability and means of survival. The giant Zentraedi that operated it often found themselves crouching, with some complaining that "It would have been easier had they just walked on their own feet". Many parts of the craft relied on being operated on manually, which increased the fatigue of the pilot. On the other hand, the overall structure was extremely simple, with relatively few failures, making operational rate high.
In space, the Regult made use of two booster engines and numerous vernier thrusters to propel itself at very high speeds, capable of engaging and maintaining pace with the U.N. Spacy's VF-1 Valkyrie variable fighter. Within an atmosphere, the Regult was largely limited to ground combat but retained high speed and maneuverability. On land, the Regult was surprisingly fast and agile, too, capable of closing with the VF-1 variable fighter in GERWALK flight (though likely unable to maintain pace at full GERWALK velocity). The Regult was not confined to land operations, though, it was also capable of operating underwater for extended periods of time. Thanks to its boosters, the Regult was capable of high leaping that allowed the pod to cover long distances, surprise enemies and even engage low-flying aircraft.
Armed with a variety of direct-fire energy weapons and anti-personnel/anti-aircraft guns, the Regult offered considerable firepower and was capable of engaging both air and ground units. It was also able to deliver powerful kicks. The armor of the body shell wasn't very strong, though, and could easily be penetrated by a Valkyrie's 55 mm Gatling gun pod. Even bare fist attacks of a VF-1 could crack the Regult’s cockpit or immobilize it. The U.N. Spacy’s MBR-07 Destroid Spartan was, after initial battel experience with the Regult, specifically designed to engage the Zentraedi forces’ primary infantry weapon in close-combat.
The Regult was, despite general shortcomings, a highly successful design and it became the basis for a wide range of specialized versions, including advanced battle pods for commanders, heavy infantry weapon carriers and reconnaissance/command vehicles. The latter included the Regult Tactical Scout (リガード偵察型). manufactured by electronics specialist Ectromelia. The Tactical Scout variant was a deadly addition to the Zentraedi Regult mecha troops. Removing all weaponry, the Tactical Scout was equipped with many additional sensor clusters and long-range detection equipment. Always found operating among other Regult mecha or supporting Glaug command pods, the Scout was capable of early warning enemy detection as well as ECM/ECCM roles (Electronic Countermeasures/Electronic Counter-Countermeasures). In Space War I, the Tactical Scout was utilized to devastating effect, often providing radar jamming, communication relay and superior tactical positioning for the many Zentraedi mecha forces.
At the end of Space War I in January 2012, production of the Regult for potential Earth defensive combat continued when the seizure operation of the Factory Satellite was executed. After the war, Regults were used by both U.N. Spacy and Zentraedi insurgents. Many surviving units were incorporated into the New U.N. Forces and given new model numbers. The normal Regult became the “Zentraedi Battle Pod” ZBP-104 (often just called “Type 104”) and was, for example, used by Al-Shahal's New U.N. Army's Zentraedi garrison. The related ZBP-106 was a modernized version for Zentraedi commanders, with built-in boosters, additional Queadluun-Rhea arms and extra armaments. These primarily replaced the Glaug battle pod, of which only a handful had survived. By 2067, Regult pods of all variants were still in operation among mixed human/Zentraedi units.

The kit and its assembly:
I had this kit stashed away for a couple of years, together with a bunch of other 1:100 Zentraedi pods of all kinds and the plan to build a full platoon one day – but this has naturally not happened so far and the kits were and are still waiting. The “Reconnaissance & Surveillance” group build at whatifmodellers.com in August 2021 was a good occasion and motivation to tackle the Tactical Scout model from the pile, though, as it perfectly fits the GB’s theme and also adds an exotic science fiction/anime twist to the submissions.
The kit is an original ARII boxing from 1983, AFAIK the only edition of this model. One might expect this kit to be a variation of the 1982 standard Regult (sometimes spelled “Reguld”) kit with extra parts, but that’s not the case – it is a new mold with different parts and technical solutions, and it offers optional parts for the standard Regult pod as well as the two missile carrier versions that were published at the same time, too. The Tactical Scout uses the same basis, but it comes with parts exclusive for this variant (hull and a sprue with the many antennae and sensors).
I remembered from a former ARII Regult build in the late Eighties that the legs were a wobbly affair. Careful sprue inspection revealed, however, that this second generation comes with some sensible detail changes, e. g. the feet, which originally consisted of separate toe and heel sections (and these were hollow from behind/below!). To my biggest surprise the knees – a notorious weak spot of the 1st generation Regult kit – were not only held by small and flimsy vinyl caps anymore: These were replaced with much bigger vinyl rings, fitted into sturdy single-piece enclosures made from a tough styrene which can even be tuned with small metal screws(!), which are included in the kit. Interesting!
But the joy is still limited: even though the mold is newer, fit is mediocre at best, PSR is necessary on every seam. However, the good news is that the kit does not fight with you. The whole thing was mostly built OOB, because at 1:100 there's little that makes sense to add to the surface, and the kit comes with anything you'd expect on a Regult Scout pod. I just added some lenses and small stuff behind the large "eye", which is (also to my surprise) a clear part. The stuff might only appear in schemes on the finished model, but that's better than leaving the area blank.
Otherwise, the model was built in sub-sections for easier painting and handling, to be assembled in a final step – made possible by the kit’s design which avoids the early mecha kit’s “onion layer” construction, except for the feet. This is the only area that requires some extra effort, and which is also a bit tricky to assemble.
However, while the knees appear to be a robust construction, the kit showed some material weakness: while handling the leg assembly, one leg suddenly came off under the knees - turned out that the locator that holds the knee joint above (which I expected to be the weak point) completely broke off of the lower leg! Weird damage. I tried to glue the leg into place, but this did not work, and so I inserted a replacement for the broken. This eventually worked.
Painting and markings:
Colorful, but pretty standard and with the attempt to be authentic. However, information concerning the Regults’ paint scheme is somewhat inconsistent. I decided to use a more complex interpretation of the standard blue/grey Regult scheme, with a lighter “face shield” and some other details that make the mecha look more interesting. I used the box art and some screenshots from the Macross TV series as reference; the Tactical Scout pod already appears in episode #2 for the first time, and there are some good views at it, even though the anime version is highly simplified.
Humbrol enamels were used, including 48 (Mediterranean Blue), 196 (RAL 7035, instead of pure white), 40 (Pale Grey) and 27 (Sea Grey). The many optics were created with clear acrylics over a silver base, and the large frontal “eye” is a piece of clear plastic with a coat of clear turquoise paint, too.
The model received a black ink washing to emphasize details, engraved panel lines and recesses, as well as some light post-shading through dry-brushing. Some surface details were created with decal stripes, e. g. on the upper legs, or with a black fineliner, and some color highlights were distributed all over the hull, e. g. the yellowish-beige tips of the wide antenna or the bright blue panels on the upper legs.
The decals were taken OOB, and thanks to a translation chart I was able to decipher some of the markings which I’d interpret as a serial number and a unit code – but who knows?
Finally, the kit received an overall coat of matt acrylic varnish and some weathering/dust traces around the feet with simple watercolors – more would IMHO look out of place, due to the mecha’s sheer size in real life and the fact that the Regult has to be considered a disposable item. Either it’s brand new and shiny, or busted, there’s probably little in between that justifies serious weathering which better suits the tank-like Destroids.
A “normal” build, even though the model and the topic are exotic enough. This 2nd generation Regult kit went together easier than expected, even though it has its weak points, too. However, material ageing turned out to be the biggest challenge (after all, the kit is almost 40 years old!), but all problems could be overcome and the resulting model looks decent – and it has this certain Eighties flavor! :D
