Nauticalia

This is a tiny, working, replica of Robert Stirling's 'hot air external combustion engine' - invented in Scotland in 1816. How does it work? Light the little alcohol (methylated spirit) burner and watch. Hot air expands, cold air contracts. The vacuum-chamber housed piston goes back and forth, making the flywheel whiz round. It doesn't really do anything useful, but is an absolute pleasure to watch! Measures 6x4", in gold-plate, hardwood and glass.
