Human-powered land vehicles

Human-powered land vehicles, such as the handcar (a human-powered railroad car), normally travel at ground level but can also travel above (for example, on a trestle) and below ground (such as when used in mining). Skateboards have the advantage of being so small and light that users can easily carry them when not skating. The most efficient human-powered land vehicle is the bicycle.[3] Compared to the much more common upright bicycle, the recumbent bicycle may be faster on level ground or down hills due to better aerodynamics while having similar power transfer efficiency. In 2009, Sam Whittingham pedaled a streamliner (a fully faired recumbent) for 200 m (660 ft) at 133.284 km/h (82.819 mph) in the Varna Tempest.[4] Velomobiles and cabin cycles are increasingly popular in colder and/or wetter countries due to the protection they offer against the environment. Freight bicycles are used as low-cost, zero-emission vehicles to haul cargo. Cycle rickshaws can be used as taxicabs. Dutch cyclist, Fred Rompelberg set a 268.8 km/h (167.0 mph) speed record at the Bonneville Salt Flats in Utah on October 3, 1995 while cycling in the wake of a motor dragster pace-car.[5] The wake of the pace-car reduced the aerodynamic drag against which Rompelberg pedalled to almost zero.[6] Greg Kolodziejzyk set two world records recognized by both the International Human Power d Vehicle Association and Guinness (TM) World Records on July 17, 2006 on a race track in Eureka, California. The first record is for the most distance traveled in 24 hours by human power 1,041 km (647 mi), and the second for the worlds fastest 1,000 km time trial (23 hours, 2 minutes).[7] In 1969, artists in a small Northern California town began the Kinetic sculpture race which has grown to a 42 mi (68 km), three-day all terrain, human-powered sculpture race and county wide event. It is held every year on the last weekend in May. This article is about the means of transport. For other uses, see Vehicle (disambiguation). Look up vehicle in Wiktionary, the free dictionary. Buses are a common form of vehicles used for public transport A vehicle (from Latin: vehiculum[1]) is a mobile machine that is designed or used to transport passengers or cargo. Most often vehicles are manufactured, such as bicycles, cars, motorcycles, trains, ships, boats and aircraft.[2] Vehicles that do not travel on land often are called craft, such as watercraft, sailcraft, aircraft, hovercraft and spacecraft. Land vehicles are classified broadly by what is used to apply steering and drive forces against the ground: wheeled, tracked, railed or skied. ISO 3833- 1977 is the standard, also internationally used in legislation, for road vehicles types, terms and definitions.[3]
