How Stirling engines work
Video (00:58 minutes, without sound):
The Stirling engine in operation and the starting and stopping procedure.
Incidentally: Modern Stirling engines attain the same efficiency as good diesel engines. The running speed is, however, relatively slow and difficult to regulate so they are less well suited for use in cars.
Information and ideas:
From second 30 the video runs in slow motion to allow better observation.
