Stirling Engine Demonstrator in detail
The story
In 1816 the Scottish minister Robert Stirling patented a hot-air engine, safer than the steam boilers of his day, which exploded with alarming regularity. Long overshadowed by the petrol engine, the Stirling cycle now works in silent submarines, solar power plants and cryogenic coolers.
What you'll see move
Turn the flywheel: the displacer and the power piston follow each other a quarter turn apart. You see the displacer shuttle the gas from the hot side to the cold side, and the power piston collect the work, exactly as in the real engine. A hand-driven teaching model: no flame, no heat.
