A model of the stirling engine. This device converts heat directly to mechanical motion, which can then be converted to electricity by attaching a generator. This type of engine has been around since the internal combustion engine, but has never been practical in something like an automobile. The Stirling Engine, however, is perfect for generating power from solar heat as you will see in the following photos.
