Hook a small motor to it. Small is key, a bike light is too big. Those toy 'stomper' trucks that run on a single AA battery is about all I would hope for. Of you want useful power you need longer blades and less of them. These are designed to turn fast with very little wind without going to fast in big winds. It should be fun and you learn, but of you want useful it is a waste of time. You're choice of goals.
