Discover the Stirling engine, a simple, clean and efficient energy technology that is quickly becoming a viable source of electricity as the availability of fossil fuels decline. The Stirling engine in this kit uses renewable energy from the sun to drive a generator, which charges a rechargeable battery to power an electric car. Today, high-tech Stirling engines are being used in arrays of giant mirrored solar collectors and common applications like compact generators. The Stirling engine uses a permanently enclosed volume of gas, such as air or helium, to perform the mechanical work. The kit includes the charging station with a mirrored parabolic dish and cylindrical glass bulb Stirling engine, an electric car, and a full-color, 64-page manual.
