solar Stirling engine ppt
The document discusses solar Stirling engines, which can convert solar energy to mechanical energy. A Stirling engine uses heat from an external source to power its operation. It was invented in 1816 and can achieve near-maximum theoretical efficiency. For solar applications, the heat source is solar energy collected via a dish collector. It then works by using pressure changes from heated gas to power pistons or generate electricity. Some benefits are its efficiency, quiet operation, and ability to provide power independent of transmission lines. It has potential applications for electricity generation, industries, homes, agriculture, and rural electrification. However, it also faces challenges in manufacturing and competing with established solar technologies.
