High as a kite -New technology is all about flying high. Researchers at the Carnegie Institution and California State are looking into using kites and high altitude wind power as an alternative energy source. The technique proposes the use of kite-like turbines that would be flown to the altitude of the jet stream and transmit the energy via a tether. Up to 40 megawatts of energy could b produced using this method. If enough kites were flown out, the power generated could meet the world demand for energy 100 times.
