Low Temperature Stirling Engine

The Low Temperature Stirling Engine is a compact, transparent Stirling engine for demonstrating the operation and fundamental design of such engines. A temperature difference of approximately 5ºC between the base and top plates is sufficient to set the motor in motion. This difference can be generated just by the warmth of a human hand or by cooling through contact with a cold object from a refrigerator. The top plate’s matte, black coat also enables the device to be operated as a solar-powered engine. In this case the direction of rotation will depend on whether the heat is applied from above or from below.

The power cylinder is made of precision glass, while the displacement cylinder and flywheel are made of acrylic glass; this allows a clear observation of the movements of the power piston, displacement mechanism and crankshaft drive. The crankshaft and connecting rod have miniature precision ball bearings.

The Stirling Engine is available in fully-assembled or kit form (for self-assembly). 


  • Runs with a temperature difference of just 5ºC between the top and bottom plates
  • Heat can be fed from below (e.g. heat from a human hand) or above (e.g. heat from the sun)
  • Transparent components make it easy to view the functioning 


  • Rotation speed: 80 rpm at ΔT = 10ºC
  • Flywheel: 110mm diameter
  • Dimensions: 138mm x 110mm diameter
