Doughnuts for (wind) dollars

Wind turbines should be able to spin a little faster and a little longer if new research by Leviathan Energy plays out.

The company came up with a method to direct the winds around a wind turbine more efficiently into the path of the blades. A doughnut-shaped plastic and metal skirt is placed at the base of the turbine, directing windflow more efficiently.

Supposedly it will increase efficiency by 15-30 percent.

We're just at the beginning stages of real advances in wind power. I can't wait until the price comes down -- and the technology improves -- to the point where I can cost-effectively add one to my home.
