I have seen sketches of those used for water pumping from a long long time ago. The only problem they have is if you have a Midwest thunderstorm come through without being there to stop it chances are you will be picking it out of your neighbors tree.

I spent 3 minutes doing this screen capture for you. Thanks for at least being interested. You go to the Chinese for a really good vertical axis windmill. I believe we can do this design much better these days. Make them with sails that contract in high winds. Build close to the ground where wind speeds are more moderate
