Why put a turbine on the ground when you can make it airborne? This inventive design looks more like a top-secret Air Force plane than a wind turbine. Designed by Makani Power, the Airborne Wind Turbine has the advantage of being able to collect wind at higher altitudes. Each propeller makes about 7.5 kilowatts of power, which is sent back down to Earth via a cable.
The turbine can be easily launched from land or from a platform out at sea. A medley of videos featuring the flying turbine in flight, and highlighting its specs, can be found at the Makani Power website.
