High-altitude kites could be used to generate clean energy at a cost comparable with that of polluting power stations, researchers claim.This would be especially effective the kites were placed somewhere with a lot of hot air blowing...I'm thinking somewhere near the UN myself...
The “Laddermill” is a chain of controllable wing-like kites attached to a looped cable stretching more than five miles into the sky.
Strong high altitude winds acting on the “kitewings” produce as upward force on one side of the loop and a downward force on the other, causing it to rotate.
The slowly-turning cable drives a power generator in the Laddermill base station.
Although the concept sounds far fetched, its developers at Delft Technical University in the Netherlands hope to build a working model in the next four years.

Kites as Alternative Energy Source
From the Scotsman:
