92348 Micro Stirling Motor, £249.00
Robert Stirling invented his engine in 1816, using an intercylinder hot-cold air-exchange system in which the heat source is external to the mechanical parts. There are no explosions, so they are very smooth, quiet and safe, but no commercial application was found until a recent reawakening of interest for localised electricity generation.
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.
