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.
The wind window is the 180 degree arc of the sky downwind of the rider in which the kite can be flown - roughly one fourth of a sphere's surface, which radius is the length of the lines. It is the atmosphere volume in which the kiter can navigate the kite to harvest wind energy.
Crosswind kite power is power derived from airborne wind-energy conversion systems (AWECS, also AWES) or crosswind kite power systems (CWKPS). The kite system is characterized by energy-harvesting parts flying transversely to the direction of the ambient wind, i.e., to crosswind mode; sometimes the entire wing set and tether set are flown in crosswind mode.
A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. [3] Some kite designs do not need a bridle; box kites can have a single attachment point. A kite may have fixed or moving anchors that can balance the kite.
Winds have various defining aspects such as velocity , the density of the gases involved, and energy content or wind energy. In meteorology, winds are often referred to according to their strength, and the direction from which the wind is blowing. The convention for directions refer to where the wind comes from; therefore, a 'western' or ...
The sport began to take off in popularity around 1972 and by the end of the 1970s it was the fastest growing sport in the world. Originally, all windsurfing boards were "long boards". This type of board went relatively slower through the water, but worked well in low wind conditions.
Glider pilots can stay airborne for hours by flying through air that is ascending as fast or faster than the glider itself is descending, thus gaining potential energy. [17] The most commonly used sources of rising air are thermals (updrafts of warm air); ridge lift (found where the wind blows against the face of a hill and is forced to rise); and
A 2010 Harris Poll found strong support for wind power in Germany, other European countries, and the United States. [145] [146] [152] Public support in the United States has decreased from 75% in 2020 to 62% in 2021, with the Democratic Party supporting the use of wind energy twice as much as the Republican Party.
