Wind Power 2.0 Science Construction Kit (8 Experiments) Thames & Kosmos

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. The six models include a glider, sail car, jet car, tractor, racecar, and tricycle.
