Scientists look high in the sky for power
Jet stream could fill global energy needs, researchers say

Scientists are eyeing the jet stream, an energy source that rages night and day, 365 days a year, just a few miles above our heads. If they can tap into its fierce winds, the world's entire electrical needs could be met, they say.

The trick is figuring out how to harness the energy and get it down to the ground cost-effectively and safely.

Dozens of researchers in California and around the world believe huge kite-like wind-power generators could be the solution. As bizarre as that might seem, respected experts say the idea is sound enough to justify further investigation.

It goes into more wonky goodness in the article, but it's not too dense for someone as simple as myself.

Big Wind = Big Energy.
