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).
On July 2, 2010, Blackbird set the world's first certified record for going directly downwind, faster than the wind, using only power from the available wind during its run on El Mirage Dry Lake. The yacht achieved a dead downwind speed of about 2.8 times the speed of the wind. [1] [18]
Land sailing. A windsport is any type of sport which involves wind-power, often involving a non-rigid airfoil such as a sail or a power kite. The activities can be land-based, on snow, on ice or on water. Windsport activity may be regulated in some countries by aviation/maritime authorities if they are likely to interfere with other activities.

An auxiliary engine will be used to navigate harbors and provide emergency power. [ 7 ] While the design is meant to be usable for different types of ships and even retrofitted to existing vessels, [ 7 ] the first vessel from the Oceanbird concept is planned to be a 200 m (660 ft) long roll-on/roll-off ship with a capacity of up to 7,000 cars.
SkySails' kite propulsion from upper wind power is a traction use of high altitude wind power. Up to 100 million tons of carbon emissions every year could be saved by widespread use of SkySails technology, according to the International Maritime Organization .
Scientists from the University of Southampton are experimenting with a new wing-sail which can be fitted to vessels to use the wind to travel. Sea trials under way for wind-powered sail in bid to ...
