NASA researchers aim to help get airborne wind power systems off the ground

NASA researchers aim to help get airborne wind power systems off the ground | Around The world  through my Eyes | Scoop.it

There are two basic types of kite-based airborne wind-energy systems. “Flygen” systems see turbines built into the kite that generate the electricity and feed it via a tether to a storage or distribution device on the ground. The second features a ground-based generator that is powered by the reeling out of the tether as the kite catches the wind. By tacking the kite upwind like a sailboat, the periodic reeling-in phase takes much less energy – around 10 percent – than is produced by the reeling-out phase, resulting in a 90 percent net energy gain
