I used to work for someone that was part owner of one of these windmills and had to put up one half million dollars as an investor.
He got a really good return on his money. They put out a tremendous amount of power I'm not sure that it's a hoax I just don't know enough about them but they are giant generators. Holland has used windmills for centuries and they ran machinery, pumps, grain grinders and all sorts of mechanics.

In the UK Scottish Power used generators to keep them turning to seem as if they were working -- Windmills great but these wind turbines are a hoax
