๐Ÿ”— Twike

๐Ÿ”— Automobiles ๐Ÿ”— Cycling

The Twike (a portmanteau of the words twin and bike) is a human-electric hybrid vehicle (HEHV) designed to carry two passengers and cargo. Essentially a velomobile with an electrical hybrid engine, it can be driven in electric-only mode or electric + pedal power mode. Pedaling warms the user, making electric heating in winter unnecessary, extends the range of the vehicle but does not substantially add to the vehicle's top speed.

Constructed of lightweight materials such as aluminium (frame) and plastic (shell), the 246ย kg (542ย lb) (unladen, varying with battery weight) tricycle vehicle first used NiCd batteries, later Li-Mn, LiFePO4 and LiIon. Typically ranges reach from 50 to over 500ย km depending on battery size, type, status on one side and speed and altitude profile and load on the other. Energy is reclaimed while driving through regenerative braking, and load is removed from the electric system by use of the pedalling system which transfers its input directly to the drivetrain (i.e., both systems operate in parallel, not in series).

๐Ÿ”— Jerrycan

๐Ÿ”— Military history ๐Ÿ”— Military history/Military science, technology, and theory ๐Ÿ”— Automobiles ๐Ÿ”— Military history/World War II ๐Ÿ”— Military history/German military history ๐Ÿ”— Military history/European military history ๐Ÿ”— Containers

A jerrycan (also written as jerry can or jerrican) is a robust liquid container made from pressed steel. It was designed in Germany in the 1930s for military use to hold 20 litres (4.4ย impย gal; 5.3ย USย gal) of fuel. The development of the jerrycan was a significant improvement on earlier designs, which required tools and funnels to use, and it contained many innovative features for convenience of use and robustness. After widespread use by both Germany and the Allies during the Second World War, today similar designs are used worldwide for fuel and water containers, some of which are also produced in plastic. The designs usually emulate the original steel design and are still known as jerrycans. The original design of jerrycan and various derivatives remain in widespread military use.

๐Ÿ”— Kei Car

๐Ÿ”— Automobiles ๐Ÿ”— Japan ๐Ÿ”— Japan/Car

Kei car (or keijidลsha, kanji: ่ปฝ่‡ชๅ‹•่ปŠ, "light automobile", pronouncedย [keหdส‘idoหษ•a]), known variously outside Japan as Japanese city car, ultramini, or Japanese microcar, is the Japanese vehicle category for the smallest highway-legal passenger cars. Similar Japanese categories exist for microvans, and kei trucks. These vehicles are most often the Japanese equivalent of the EU A-segment (city cars).

The kei-car category was created by the Japanese government in 1949, and the regulations have been revised several times since. These regulations specify a maximum vehicle size, engine capacity, and power output, so that owners may enjoy both tax and insurance benefits. In most rural areas they are also exempted from the requirement to certify that adequate parking is available for the vehicle.

Kei cars have become very successful in Japan, consisting of over one-third of domestic new-car sales in fiscal 2016, despite dropping from a record 40% market share in 2013, after the government increased the kei-car tax by 50% in 2014. In 2018, seven of the 10 top-selling models were kei cars, including the top four, all boxy passenger vans: Honda N-Box, Suzuki Spacia, Nissan Dayz, and Daihatsu Tanto. Isuzu is the only manufacturer that has never offered a kei-sized vehicle for either private ownership or commercial trucks and microvans.

In export markets, though, the genre is generally too specialized and too small for most models to be profitable. Notable exceptions exist, though, for instance the Suzuki Alto and Jimny models, which were exported consistently from around 1980. Kei cars are not only popular with the elderly, but they are also popular with youths because of their affordability.

Nearly all kei cars have been designed and manufactured in Japan, but a version of the French-made Smart was briefly imported and officially classified as a kei car, and since then, the British Caterham 7 160 has also received such classification.

๐Ÿ”— Trabant

๐Ÿ”— Germany ๐Ÿ”— Brands ๐Ÿ”— Automobiles ๐Ÿ”— Germany/GDR

Trabant (German: [tสaหˆbant] ) is a series of small cars produced from 1957 until 1991 by former East German car manufacturer VEB Sachsenring Automobilwerke Zwickau. Four models were made: the Trabant 500, Trabant 600, Trabant 601, and the Trabant 1.1. The first model, the 500, was a relatively modern car when it was introduced.

It featured a duroplast body on a steel chassis, front-wheel drive, a transverse two-stroke engine, and independent suspension. Because this 1950s design remained largely unchanged until the introduction of the last model, the Trabant 1.1 in 1990, the Trabant became symbolic of the former East Germany's stagnant economy and the collapse of the Eastern Bloc in general. Called "a spark plug with a roof", 3,096,999 Trabants were produced. Older models have been sought by collectors in the United States due to their low cost and fewer restrictions on the importation of antique cars. The Trabant also gained a following among car tuning and rallying enthusiasts.

๐Ÿ”— Gyrocar

๐Ÿ”— Russia ๐Ÿ”— Russia/technology and engineering in Russia ๐Ÿ”— Automobiles

A gyrocar is a two-wheeled automobile. The difference between a bicycle or motorcycle and a gyrocar is that in a bike, dynamic balance is provided by the rider, and in some cases by the geometry and mass distribution of the bike itself, and the gyroscopic effects from the wheels. Steering a motorcycle is done by precessing the front wheel. In a gyrocar, balance was provided by one or more gyroscopes, and in one example, connected to two pendulums by a rack and pinion.

The concept was originally described in fiction in 1911 "Two Boys in a Gyrocar: The story of a New York to Paris Motor Race" by Kenneth Brown, (Houghton Mifflin Co). However the first prototype Gyrocar, The Shilovski Gyrocar, was commissioned in 1912 by the Russian Count Pyotr Shilovsky, a lawyer and member of the Russian royal family. It was manufactured to his design by the Wolseley Tool and Motorcar Company in 1914 and demonstrated in London the same year. The gyrocar was powered by a modified Wolseley C5 engine of 16โ€“20ย hp, with a bore of 90ย mm and a stroke of 121ย mm. It was mounted ahead of the radiator, driving the rear wheel through a conventional clutch and gear box. A transmission brake was fitted after the gearbox โ€“ there were no brakes on the wheels themselves. The weight of the vehicle was 2.75 tons and it had a very large turning radius.

In 1927 Louis Brennan, funded to the tune of ยฃ12,000 (plus a ยฃ2000 per year) by John Cortauld built a rather more successful gyrocar. Two contra-rotating gyros were housed under the front seats, spun in a horizontal plane at 3500 rpm by 24V electric motors powered from standard car batteries. This was the greatest speed obtainable with the electric motors available, and meant that each rotor had to weigh 200ย lb (91ย kg) to generate sufficient forces. Precession was in the vertical fore-aft plane. The car had a Morris Oxford engine, engine mountings, and gearbox. Two sidewheels (light aircraft tailwheels were used) were manually lowered on stopping; if the driver forgot and switched off the gyros and walked away, the car would continue to balance itself using the gyro momentum for a few minutes, and then the wheels would automatically be dropped to stop tipping.

๐Ÿ”— Sinclair C5 Electric Car (1985)

๐Ÿ”— Automobiles ๐Ÿ”— Engineering

The Sinclair C5 is a small one-person battery electric velomobile, technically an "electrically assisted pedal cycle". It was the culmination of Sir Clive Sinclair's long-running interest in electric vehicles. Although widely described as an "electric car", Sinclair characterised it as a "vehicle, not a car".

Sinclair had become one of the UK's best-known millionaires, and earned a knighthood, on the back of the highly successful Sinclair Research range of home computers in the early 1980s. He hoped to repeat his success in the electric vehicle market, which he saw as ripe for a new approach. The C5 emerged from an earlier project to produce a small electric car called the C1. After a change in the law, prompted by lobbying from bicycle manufacturers, Sinclair developed the C5 as an electrically powered tricycle with a polypropylene body and a chassis designed by Lotus Cars. It was intended to be the first in a series of increasingly ambitious electric vehicles, but the development of the follow-up C10 and C15 models never got further than the drawing board.

On 10 January 1985, the C5 was unveiled at a glitzy launch event but it received a less than enthusiastic reception from the British media. Its sales prospects were blighted by poor reviews and safety concerns expressed by consumer and motoring organisations. The vehicle's limitations โ€“ a short range, a maximum speed of only 15 miles per hour (24ย km/h), a battery that ran down quickly and a lack of weatherproofing โ€“ made it impractical for most people's needs. It was marketed as an alternative to cars and bicycles, but ended up appealing to neither group of owners, and it was not available in shops until several months after its launch. Within three months of the launch, production had been slashed by 90%. Sales never picked up despite Sinclair's optimistic forecasts and production ceased entirely by August 1985. Out of 14,000 C5s made, only 5,000 were sold before its manufacturer, Sinclair Vehicles, went into receivership.

The C5 became known as "one of the great marketing bombs of postwar British industry" and a "notoriousย ... example of failure". Despite its commercial failure, the C5 went on to become a cult item for collectors. Thousands of unsold C5s were purchased by investors and sold for hugely inflated prices โ€“ as much as ยฃ5,000, compared to the original retail value of ยฃ399. Enthusiasts have established owners' clubs and some have modified their vehicles substantially, adding monster wheels, jet engines, and high-powered electric motors to propel their C5s at speeds of up to 150 miles per hour (240ย km/h).

๐Ÿ”— Unsafe at Any Speed

๐Ÿ”— Books ๐Ÿ”— Automobiles

Unsafe at Any Speed: The Designed-In Dangers of the American Automobile is a non-fiction book by consumer advocate Ralph Nader, first published in 1965. Its central theme is that car manufacturers resisted the introduction of safety features (such as seat belts), and that they were generally reluctant to spend money on improving safety. This work contains substantial references and material from industry insiders. It was a best seller in non-fiction in 1966.

๐Ÿ”— Electro Gyrocator

๐Ÿ”— Automobiles

The Electro Gyro-Cator was claimed to be the world's first automated commercially available automotive navigation system. It was co-developed by Honda, Alpine, and Stanley Electric Co..

Unlike most navigation systems of today, it did not use GPS Satellites to maintain its position and discern movement of the vehicle. Rather, it was an Inertial navigation system, because it contained a helium gas gyroscope that could detect both rotation and movement. A special servo gear was also attached to the transmission housing to feed information to the Gyro-Cator to help maintain position, map speed and distance traveled.

Transparent maps were placed inside the unit and it would scroll them past a 6 inch monochrome CRT illuminated screen as the car traveled along. The monitor would indicate by a series of circles (or cross hairs) on the screen to show the vehicle's current location or display lines for path of travel. A marking pen was also included to help make personal indicators on the map if needed. Adjustments could be made to change the display scale, position, rotation, brightness, and contrast. In its only year of production in 1981, it was announced as an option on that year's Honda Accord and Honda Vigor, but at ยฅ300,000 ($2,746 USD), it was almost a quarter of the value of the car. It is not clear how many units were actually sold to customers as a "dealer option". A patent for gyroscope design was introduced to the US in design patent D274332.

Documented weight for the unit was roughly 20ย lb (9ย kg). A display unit, with a cutaway of the Gyroscope, is currently shown at the Honda Collection Hall at Twin Ring Motegi, Japan.
