The Pack Rat Work Shop
This was the first Savonius type wind turbine I built. It is highly modified and drawn according to some plans I found on the net that came from some school. I don't remember exactly where but when I find it again I will put a link here for it.
This one is about 19 inches in diameter and close to
the same on height. It is made from 1/4" plywood and sheet
metal recycled from aluminum siding.
It's really more of a yard ornament than it is anything else but it was good practice in finding an easy way to build small vertical turbines.
