Windmill

I've read a lot about it, and I want to draw your attention to the idea which says on the battery charge electric cars with wind.
I think it is full of possibilities, as with wind power converter is not changed at the drag cars. And the weight of the entire system (material-aluminum) would be about 40 kg. I even have a rough drawing of the device. I believe that nothing is impossible!
