American Wind Energy Associaton left me feeling sour for a few years. Someone asked the simple question about how to make more power with his home made genset. I read his suppled info on how it was designed and concluded that a bigger blade set was the simplest way to go. That was it, no complicated math theory on aerodynamics or any thing. just simple common sense!
I got shot all to pieces! What kind of idiot would propose using a bigger blade to catch more wind? aparently I should have answered with three pages of mathematical nonsense and told the poor guy he needs to go to an aerospace engineering company and spend a few hunderd thousand and have them reshape his wood blades to get a theoretical 10% more efficiency.
