Gas Street, Concord, New Hampshire
Reference number: 100001962
The Concord Gas Light Company Gasholder House, in Concord, New Hampshire, is the last remaining example of a gasholder house in the United States that retains its interior wrought-iron gasholder. The storage tank held purified manufactured coal gas. The cylindrical brick structure was designed and erected by Deily & Fowler of Laurel Iron Works, Philadelphia. During the second half of the nineteenth century, coal gas was an important fuel for municipal, industrial, and domestic illumination and, therefore, played a significant role in the growth of American cities and industry. The Concord Gas Light Company, suppliers of illuminating gas to City of Concord, installed the Gasholder House in 1887–1888, during one of several late-nineteenth-century improvements to its facility on South Main Street.

From the 1946 catalogue issued by the Mitchell Engineering group, a company whose interests spanned a wide range both the manufacturing of many types of engineering equipment as well as constructing and fitting out industrial and commercial buildings and structures. One of their areas of expertise was in electricity generating where they made boilers, fuel handling an ash disposal equipment.
Seen here is a contract undertaken for the pre-nationalisation municipal electricity undertaking of Bristol City Council. The City Council had started to generate electricity in 1891 but by the mid-1920s the two original stations, within the city, were proving too small and increasingly obsolete. Construction at the dockside site at Portishead began in 1926 and the station was commissioned in 1929. As a 'selected' station it provided power to the National Grid under the control of the Central Electricity Board. In 1937 the station underwent partial reconstruction including the erection of this single chimney stack, seen here, to replace the original six seperate steel ones. It was, in post war years, joined by Portishead "B" station, at which point this became "A" and after a short period following conversion to oil firing after local coal fields became exhausted and closed, A station ceased generation in 1976 with demolition of the chimneys taking place in the early 1980s - B station closed in 1982.
Stone wall at Mihintale. I tend to believe that there is a reason why some stones are at an angle and have 5 edges. They could have easily straighten it up, given what we can see around.
This is a laser cut piece of steel we keep in Civil Club, which represent the VW shell of UBC Engineering. UBC engineers are famous for their pranks on Engineering week. Every year on the first day of Engineering week, UBC undergrad engineers hang a VW shell with a red E on it from a bridge! Where? Who knows, it could be our beautiful Lions Gate Bridge, or Golden Gates of California! I know it's not the best prank, but it has turned into a tradition since decades ago.
E week is in February, but I'm studying too much E-material these days that I liked to post this.
Hopefully this year, in Feb, I will take pictures of the hung VW from "a bridge"!

Speaking of engineering and bulky costumes. "Iron Man" is another interesting challenge. I've read that it's taken the designers of the "real" costume three movies to figure out how to make the armor work without pinching the hell out of the actor.
So the challenge for cosplayers is to make it lightweight, comfortable, practical, and affordable. Like all engineering challenges, it's always a question of "how do we define the goal of this project?" and then giving yourself the freedom to jettison ideas and features that you "want" instead of "need," if necessary.
What good is a rigid costume that you can wear for about 27 minutes before you cry "uncle"? I've seen people in chain-mail suits who looked — what a surprise — like they were carrying 72 pounds of metal all over their bodies. Hardly happy campers and you rarely see them twice on the same day.
This set of Iron Man armor is made of foamcore, it seems, and it looks great. Would it fool you into thinking it's the movie costume? Of course not, but that's not really the goal of cosplay. It hits all of the design points, it's well-executed, and you can look at it without thinking "Oh, that poor, poor man..."

Our middle-school students at Tam High are building a City of the Future together, using arts and electronics to make a model of what our world may be like in 100 years.
In our sixth class, students worked in teams to make public spaces for their city: underwater mines, segregated neighborhoods, surface rubbles and gated skyscrapers for the rich. This week’s creations included a new city sign, more ladders, more mine workers, and tall, skinny towers scraping the crimson sky.
They also agreed on a final name for their city: 15A, named after its sector coordinates. In their post-apocalyptic city of the future, the rich are separated from the poor, who mine the sea floor and are oppressed by a government run by machines.
I am teaching this after-school class with Geo Monley and Cynthia Gilbert, and we are happy to see our students so engaged in this project. Through this course, they are developing a range of skills, from creative expression to science and engineering (STEAM). And they are learn to create interactive art with simple electronics, in a playful and collaborative way that makes learning more fun.

The Rendsburg High Bridge (in German: "Rendsburger Hochbrücke") with its suspension ferry (in German: "Schwebefähre") crossing the Kiel Canal (in German: "Nord-Ostsee-Kanal") on the left, Rendsburg, Schleswig-Holstein, Germany
Some background information:
The Rendsburg High Bridge (officially: "Eisenbahnhochbrücke Rendsburg") is a railway viaduct on the Neumünster–Flensburg line that also serves as a transporter bridge. The bridge, which is made out of steel, crosses the Kiel Canal at Rendsburg in the German state of Schleswig-Holstein. It is owned by the Federal Water and Navigation Administration that also owns and runs the canal.
The Kiel Canal (formerly known as the "Kaiser-Wilhelm-Kanal") is a 98 km (61 miles) long freshwater canal in the German state of Schleswig-Holstein. The canal was finished in 1895, but later widened. It links the North Sea at Brunsbüttel to the Baltic Sea at Kiel-Holtenau. An average of 460 km (290 miles) is saved by using the Kiel Canal instead of going around the Jutland Peninsula. This not only saves time but also avoids storm-prone seas and having to pass through the Danish straits. The Kiel Canal is one of the world's most frequented artificial waterways with an annual average of 32,000 ships (90 daily), transporting approximately 100 million tons of goods.
The first connection between the North and Baltic Seas was constructed while the area was ruled by Denmark–Norway. It was called the Eider Canal and used stretches of the Eider river for the link between the two seas. Completed during the reign of Christian VII of Denmark in 1784, the Eider Canal was a 43 km (27 miles) part of a 175 km (109 miles) waterway from Kiel to the Eider river's mouth at Tönning on the west coast. It was only 29 m (95 feet) wide with a depth of 3 m (9.8 feet), which limited the vessels that could use the canal to 300 tons.
After 1864, the Second Schleswig War put Schleswig-Holstein under the government of Prussia (from 1871 the German Empire). A new canal was sought by merchants and by the German navy, which wanted to link its bases in the Baltic and the North Sea without the need to sail around Denmark. In June 1887, construction started at Holtenau, near Kiel. The canal took over 9,000 workers eight years to build. In 1895, emperor Wilhelm II officially opened the canal for transiting from Brunsbüttel to Holtenau. The next day a ceremony took place in Holtenau, where Wilhelm II named the waterway the Kaiser-Wilhelm-Kanal (after his grandfather, emperor Wilhelm I), and laid the final stone.
To cope with the increasing traffic and the demands of the Imperial German Navy, between 1907 and 1914 the canal was widened by Germany to allow dreadnought battleships to pass through. Two larger canal locks in Brunsbüttel and Holtenau were installed to complete the enlargement. After World War I, the Treaty of Versailles required the canal to be open to vessels of commerce and of war of any nation at peace with Germany, while leaving it under German administration. Only the United States opposed this proposal to avoid setting a precedent for similar concessions on the Panama Canal. The government under Adolf Hitler repudiated its international status in 1936, but the canal was reopened to all traffic after World War II. In 1948, its current name was adopted.
The canal is governed by detailed traffic rules. Each vessel using the canal is categorized into one of six traffic groups according to its dimensions. Larger ships are obliged to accept pilots and specialized canal helmsmen, in some cases even the assistance of a tugboat. Furthermore, there are regulations regarding the passing of oncoming ships. Larger ships may also be required to moor at the bollards provided at intervals along the canal to allow the passage of oncoming vessels. All permanent, fixed bridges crossing the canal since its construction have a clearance of 42 m (138 feet).
Maximum length for ships passing the Kiel Canal is 235.50 m (772.6 feet), with the maximum width (beam) of 32.50 m (106.6 feet). These ships can have a draught of up to 7.00 m (22.97 feet). Ships up to a length of 160.00 m (524.93 feet) may have a draught up to 9.50 m (31.2 feet). The bulker Ever Leader (deadweight 74,001 t) is considered to be the cargo ship that to date has come closest to the overall limits.
When the Kiel Canal was built, it cutted through existing traffic lines including the railway line between Neumünster and Flensburg for which two parallel swing bridges were erected. Main railway lines had right of way over ships on the canal and ships had to stop, losing about half an hour when a train passed. This was considered the major obstacle as the ships were unable to overtake and could pass each other at dedicated enlarged areas so that the traffic on the entire canal was hampered. Especially the navy pressed for a separation of traffic flows as closed bridges could delay flotillas by several hours.
In order to allow the railway line to pass above the canal, the new railway bridge was to have a clearance of 42 metres over the canal's mean water level. It was erected between 1911 and 1913 to a design by the civil engineer Friedrich Voss and replaced the earlier swing bridges. The steel viaduct has a length of 2,486 metres (8,156 feet) and is supplemented by embankments that bring the overall length of the structure to about 7.5 kilometres (4.7 miles). The cantilever main bridge is 317 metres (1,040 feet) long, has a main span of 140 metres (460 feet).
To serve Rendsburg station, situated at ground level only a couple of hundred metres from the main bridge, the railway line is routed through a large 360-degree loop on the north bank of the canal. The total cost of the construction, including the relocation of railway lines but excluding work related to the elevation of Rendsburg station, was 13.4 million Mark Today, this figure would correspond to roughly 66 million Euro. It included 5.7 million Mark for bridges, 2.7 million Mark for the mounds and 1.3 million Mark for underpasses and the relocation of roads.
The suspension ferry is already in operation since the bridge’s opening in 1913. Since then even its timetable was never changed. It runs daily every 15 minutes from early morning until late at night. It covers a distance of 125 metres (410 feet) within 1½ minutes and provides the shortest connection between the municipality of Osterrönfeld and the town of Rendsburg. As this means of transportation is especially useful to students on their way to school, larger maintenance work that requires suspension of service is coordinated with school holidays.
The gondola is fourteen metres long and six metres wide, and travels six metres above the canal. In recent years the nominal transport capacity has been reduced from six to four automobiles in order to factor in increased car size and weight. While the gondola is equipped with nautical equipment such as radio, radar and life-rafts, there is no prerequisite for the operator to hold a master's licence for inland navigation.
The suspension ferry met with two major accidents: During a storm in 1993, the unmanned and unlit gondola broke loose at night, was blown over the canal and collided with a ship. But both ship and gondola suffered only minor damage. In 2016 the gondola of the transporter bridge collided with the general cargo ship Evert Prahm and was heavily damaged. Two people, the waterman and the only passenger, were injured. After that, the suspension ferry was demounted and moved to a shipyard, but was found to be irreparably damaged. Construction of its replacement (optically almost true to original) began in 2020 and service resumed in 2022.
At the time, the Rendsburg High Bridge was built, it was regarded as a prime example of the German art of engineering. In 2013, it was awarded a "Historic Icon of German art of Engineering" (in German: "Historisches Wahrzeichen der Ingenieursbaukunst in Deutschland") by the German Chamber of Engineers and hence, also by the Federal Government of Germany. By the way, whenever a ship passes through the Rendsburg High Bridge, it is welcomed by a loudspeaker announcement, the sound of a bugle and last but not least the national anthem of the country, under whose flag it sails. You can imagine that watching the different ships passing by is quite entertaining.
