(48) Gary Hart's Stirling Low Temperature Differential Engine

This is one of the prettiest Low Temperature Differential Engines I've seen. It is running from the cold generated by sitting on ice cubes. It will run in the opposite direction if it is setting on a heated surface.

Olympus C-300Z
1/30s f/5.6 at 6.0mm iso100 with Flash full exif

other sizes: small medium large original auto
