The vehicle draws power from the faster of the two media in each case and imparts it to the slower of the two: upwind, drawing power from the wind and imparting it to the wheels and, downwind, drawing power from the wheels and imparting it to the rotor: in each case in proportion to the velocity of the medium, relative to the vehicle.

Wind-powered vehicles derive their power from sails, kites or rotors and ride on wheels—which may be linked to a wind-powered rotor—or runners. Whether powered by sail, kite or rotor, these vehicles share a common trait: As the vehicle increases in speed, the advancing airfoil encounters an increasing apparent wind at an angle of attack ...
Greenbird is a wind-powered vehicle that broke the land speed record for sail-powered vehicles at the dry Ivanpah Lake on March 26, 2009. [1] It was built by the British engineer Richard Jenkins. Greenbird reached a peak speed of 126.1 mph (202.9 km/h). [2]
High-performance watercraft that can exceed the speed of the true wind include sailing catamarans and foiling sailing craft. Ice boats and land-sailing craft are often able to do so. There are also wind-powered vehicles that can travel faster than the wind, such as the rotor-powered Blackbird, which are outside the scope of this article.
The U.S. government chose winning bids Tuesday to develop wind power off New England in the first commercial sale for floating offshore wind on the Atlantic coast. The Bureau of Ocean Energy ...
Sailing downwind, the apparent wind decreases the more the ship speeds up and at exactly the true wind speed, would drop to zero, so that the wind turbine can generate no power and also no thrust if used in the autogyro mode. Therefor windmill ships are limited to less than wind speed when travelling directly downwind, as with other sailing craft.

Land sailing, also known as sand yachting, land yachting or dirtboating, [1] entails overland travel with a sail-powered vehicle, similar to sailing on water. [2] Originally, a form of transportation or recreation, it has evolved primarily into a racing sport since the 1950s. Vehicles used in sailing are known as sail wagons, sand yachts, or ...
