.: wind turbine kites to fly at 30,000 feet

Topic science & new tech (By Cif!, Sunday 25 October 2009 @12:59)

Researchers at Stanford University are trying to design high-altitude wind turbine kites that fly so high that airliners would have to fly around them. Flying an expected 30,000 feet above the Earth, the tethered kites would be able to reach powerful jet streams that can flow 10 times faster than winds closer to the ground.

According to Ken Caldeira, «If you tapped into 1% of the power in high-altitude winds, that would be enough to continuously power all civilization». He added that to generate the same amount of power, solar cells on the ground would have to cover roughly 100 times more area than a high-altitude wind turbine..
