Playing with wind power

[suicideneil]

Ever seen those spinning signs they have outside some shops powered by the wind, they have one word on the back (top) and another on the front (bottom); when the sign spins you see both words together.. (like 'fish & chips') etc. Stick a shaft down the middle and mate that to your motor via the belt drive or whatever you plan to use...

They are shaped basically the same as the turbine you want to use, only in a single molded piece.
