Subject:      wind power math

Can someone give me a hand, please?

I'm concerned about how much horsepower I can get from a vertical shaft windmill
made from 2 50 gallon oil drums split long-ways, aligned long axis parallel to
shaft, and welded to the shaft to form 4 wind pockets.

So, what kind of power could I get if I had a really efficient rotation base for
the shaft to stand on?  I'd keep the shaft vertical with guy wires.

Can someone point me to the right equations?

Many thanks,

Rolfe
