Build wind-powered generators to energize your electric vehicles and charge your rechargeable batteries. The wind spins the turbine, which turns an electric generator, which in turn charges your rechargeable AA batteries (not included). You can then use those wind-charged batteries to power the model vehicles you build with our kit. The six models include a glider, sail car, jet car, tractor, racecar, and tricycle.

This kit includes two styles of wind turbine blades and a gearbox with three different gear ratios for experimenting. You can adjust the angle and number of wind turbine blades to make best use of wind, to make the LED light up brightly, and to charge the rechargeable battery as fast as possible. Explore this amazing, free source of renewable energy and store the electricity you generate for use in practical applications.

This kit includes a 40-page color instruction book with illustrated step-by-step instructions for assembling two windmills and six model vehicles, and conducting various experiments. The 133 building pieces included in this set are compatible with those in our Air + Water Power, Remote Control Machines, and Solar Power kits.

Ages 8 and up.
