I appreciate the benefits of solar power, wind power, hydropower, and other alternative energy sources, but do I really understand how they work? To be honest, no. Of course not. This little Loopwing Wind Power Generator Set, by Tamiya, Inc. is a great idea for ignoramuses like myself who want to see with our own eyes how one harnesses and converts wind into energy. The wing catches the breeze, converts it to electricity and powers the little model car, which you can then watch in action.

Available for $46.49 at Amazon.
