Using Kites for Wind Power

The Kite Gen concept is simple: large controllable “kites” are drawn upward to altitudes around 800 meters, where average wind speeds are much greater than near the ground where current windmill designs reside. As these remotely controlled airfoils rise, their tethers power turbines on the ground while also maintaining control over their flight path. After reaching their maximum height, the kites are flown back down to ground level as motorized spools gather the tether. The retrieval phase requires only a small fraction of the power that is generated during the flight.
