Hi David

Probably not, they are low voltage motors and you would be lucky to get over 1 volt as a windmill. A better motor would come from a old printer, but you wont really know unless you build the windmill and try a few different motors to see what gives the highest voltage.

Hi Glenn,
I hooked up my little slot car motor and made a little vawt with a laundry detergent cap placed a large funnel to channel wind to one side and its pumping out 3 volts in a 7mph wind.
I think the funnel helps a lot!!!!
