WOW!!!
I've heard vague references to this kind of technology for several years, but I had no idea that a proven design existed. This looks like it is worthy project.
At one time wind turbines were scoffed as being impractical, but there are thousands of them all over the place, and they are putting a lot of power into the grid.
I hope someone gets behind this one and soon...
They are putting unreliable power into the grid which must still be backed up with expensive power plants to cover the times when the wind doesn't blow. Windfarms are another feelgood environmentally correct (unless Teddy Kennedy can see them from his front porch) form of energy. They might actually contribute if they can find more efficient batteries to store excess energy.
