Stirling Engine A description of a Stirling engine. The engine is made of a glass tube with empty displacer inside. The working piston-membrane is made of a rubber glove. Hot reservoir is heated by a flame of gas. The engine has a heavy weight on the arm, which changes position of center of mass. It causes balancing moves of the engine and shifts the displacer inside the tube. Finally the engine rotate about 1 minute. The efficiency of the Stirling engine is similar to that of the Carnot cycle.
