I am helping my sister with a high school project to demonstrate how a small wind turbine works. We're only looking to light a few LED's.

I found this small DC motor on ebay, and was wondering if it would be good to use for this project, since the RPM rating of this motor is so low.

120RPM / 12v DC = 10RPM per watt

Your suggestion??? The motor I'm looking at is here:

The reason the motor has such a low RPM rating is that it has an internal gear box attached. The question is if your wind blades will develop enough torque to be able to turn the motor backwards. I don't know the answer to that.
