Since we all love to recycle, I thought I'd ask if anybody has tried using helicopter rotor blades as a wind turbine?
Since the blades are usually designed to operate with tips speeds approaching the speed of sound, and the lift loads can get quite high, I'd say that they're over-designed for the task. That said, it's all built for you....
I know, some of you will say it's a crazy idea. But that doesn't mean someone hasn't tried it anyway...
