High-altitude wind energy using kite: A revolution in renewable energy
A mechanism is designed to convert the oscillating tether tension, caused by the vertical motion of a kite, into rotary shaft motion to drive a generator. Another mechanism is designed which converts the continuous pull of the kite into electric power. The design uses a commercially-available parafoil kite which is 4.5 meters squared in size which is found to be useful.
Link: Generating electricity using kites instead of wind turbines have certain advantages like generating power at low cost while eliminating certain environmental problems associated with wind turbines;
kites can fly at greater heights than wind turbines.
Since wind speed increases with height and the available power are proportional to wind speed cubed, the wind power potential is larger for kites.
