Harness Wind Power with Electricity Generating Turbines Build
wind-powered generators to energize your electric vehicles and
charge your rechargeable batteries. When wind spins the turbine,
an electric generator turns, 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,
including 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. Simply 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, plus cond
