futurescope:Wind turbine generates energy floating 350 feet off the groundTrials have just been finished on a new kind of wind turbine — an inflated, helium shell containing traditional blades that floats in the air stream. The airborne turbine is designed to capture stronger, high-altitude winds to provide a clean, portable and power energy option.In the recent tests held in Limestone, Maine, a 35-foot scale version of the turbine was shown to generate more than twice as much power at high altitude than generated at conventional tower heights.The Altaeros Airborne Wind Turbine (AWT) is transported to its location by a towable, docking trailer. The AWT is then deployed — in this trial some 350 feet above the ground — and held in place by tethers which also send the electricity generated back to the ground. Raising, operating and lowering the turbine was successfully completed a in fully automated cycle. […][more] -- source link
