A Stirling Engine is an external combustion engine that can run on many different heat sources. The Stirling Engine has the capability to produce power from both bio-fuels and focused sun rays, thus making it a viable green technology. In our project, A Fresnel lens is utilized to direct the rays of the sun onto the heat exchanger of the Stirling Engine. The Fresnel lens is advantageous to a standard lens as it, due to its unique design, is lightweight and transportable, just like a simple sheet of plastic.
