High altitude wind energy from kites
A California company, Makani Power (www.makanipower.com), received a $10 million grant from Google to construct a system of extremely high-flying kites to exploit the fact that winds are much stronger and steadier thousands of feet above the ground. Earthbound wind turbines reach only up to 300 feet.

High-altitude windmills could provide 250 times the energy!
Using a conservative approach, they counted only the energy that could be generated from winds blowing over land at an altitude of 80 meters, the approximate height of a typical modern wind turbine. Under perfect conditions, the total would be 72 trillion watts. A few miles up, a turbine blade could generate up to 250 times the energy of the same blade near the ground. - Read More
