Wind picked up on Thursday, tore the turbine. *BUT* got some good voltage out of it before I pulled it in. I didn't want it flying through the neighborhood and breaking something, or littering. Since the design works well enough, I can start looking for some Aluminum siding or flashing to make the blades bigger. I'll work this one backwards, and design the circumfrence to match the width of the finished blade, since there will be a limit to the width of the flashing or siding.
I still want to get pics of all this at some point.

Oh, well...
