The Renewable Energy Experiment Kit is a complete eco toy that allows children to experiment with different renewable energy sources. The kit includes a wind turbine, a solar cell, electrolytic cells and a hand-powered dynamo which can all be used to generate electricity. The generated electricity is stored in a built-in rechargeable battery, and the effectiveness of each energy source can be measured using the built-in voltmeter.
Once the internal battery has been charged, the battery can be used to power a motor, LEDs, and a buzzer using the provided alligator clips. The kit also comes with an educational booklet which explains the different methods for reducing energy costs at home as well as energy generating methods in the real world.
The Renewable Energy Experiment Kit is available for $49.95 from Hammacher Schlemmer.
