Low Temperature Stirling Engine

by United Scientific

Use this little stainless beauty to teach teenagers and older students how heat engines work. This low-temperature-differential Stirling engine is beautifully machined. It works with hot water, ice water, a combination of hot water with ice cubes, or a hair dryer. The bigger the temperature differential the faster it runs, though it requires an approximate 50°F temperature difference between the top and bottom plates. It runs by exploiting the heat flow generated by the small temperature differences between room temperature and a container of hot water or ice. The Stirling Engine is an External Combustion Engine (the heat source is outside the engine) and can use any available source of adequate temperature.

 It measures 5-3/4″ tall with a 3-5/8″ dia flywheel and a 3-1/2″ dia x 7/8″ tall base. An instruction manual is included with the engine.
