Wind Power

I just learned about a company making a new kind of wind turbine.  The company is called Makani Power and the wind turbines they build are unlike anything else I've ever seen.  They have a flying wing, tethered like a kite to the ground that flies in circles to generate power.  They use 90% less material, can operate over deep water and can access winds at higher altitudes than conventional wind turbines.
I'm thinking that, given global climate change, the fact that these are relatively portable to relocate as conditions change, is a huge plus.
