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 declines. 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. Named after its inventor, Robert Stirling, the original Stirling engine dates back almost 200 years. Today, high-tech Stirling engines are being used in arrays of giant mirrored solar collectors and common applications like compact generators.
