Green Science Windmill Generator by Toysmith

Green Science Windmill Generator by Toysmith
I am pleased by the fact that many of the newer mechanical toys have "green" theme. Take this small scale wind generator. The Windmill Generator has a gear motor (which serves as a generator) and 6 inch propeller with a tail. After a bit of assembly you can watch the wind light up its LED bulbs.

From the product description:
How is energy produced by using windmills? Build this amazing wind generator and learn about renewable energy/ "green energy". Watch the LED glow as it is powered by free energy from the wind. No batteries required! Help save the planet by using a recycled plastic bottle to support your wind generator. Ages 8+
