I wouldn't bother with trying to make it efficient. I like the idea of
half oil drums mounted vertically, with the motor on the ground.

There are some interesting vertical-axis ideas around. At least you don't
have to worry about wind direction that way. It might prove to be a lot
more noisy though.
