Don't need to make any power, unless it's a gimme. So a drag device will do just fine.
Since the 'pushers' can only spin as fast as the wind is moving, it can be my wind-speed indicator.
Plus, I think it might keep the birds out of the area where it's installed.

I've noticed that our little plastic penguin with propeller arms on the deck railing
does keep the birds away when the wind is over 2 MPH..

I was looking at the FG 'blades' I have and trying to figure out a hub piece,
and I think the 4 blade will be the easier to built, since it just needs
a square block to mount the blades to. Wooden 4x4 maybe?
