Stirling Engine Kit

This fully functional Stirling Engine runs on a HOT cup or an ICE pack. Ingenious and simple: Heat or cool a cylinder (put it on a cup of coffee) and the piston moves air back and forth (technical word 'pists'). In this way, the air is alternatively heated and cooled, creating a cycle of compression and expansion, of high and low air pressure. A working piston, connected to the main cylinder, is kept in motion by the alternating air pressure, and in turn moves a crankshaft and flywheel. Height 16.5cm wide and 12.6cm deep. There is a commercial gadget on the market that sits on a stove and the heat from the stove allows the Stirling Engine to pump the warm air out into the room. Ours is made of stout card so be careful!
