Mirrored dish
Resembling large satellite dishes, these giant mirrored dishes collect solar radiation and use it to generate electricity in a novel way. Each dish bears its own Stirling engine, which works by using heat to expand a hot gas that drives pistons to produce electricity. Developed by Stirling Energy Systems, early versions are in use at Sandia National Laboratories in New Mexico.
