High-Altitude Tethered Wind Turbine

In the video below, Altaeros Energies uses a scale prototype to demonstrate the ability of wind-turbine generators lifted 1,000 feet high (about three times the height of typical wind turbines) to produce twice the power output. Lift is provided by a helium-filled, inflatable shell. The technology is being developed for military, offshore, and other remote needs.
