Stirling Engine With Alcohol Burner

Nearly a century after it was invented, the Stirling Engine is still a unique and fascinating heat machine. Our desktop model allows your students to witness thermodynamics in action! The Stirling Engine Model uses a closed-cycle system in which air is compressed and expanded at different temperatures to create energy. Vividly demonstrates how thermal expansion and cold shrinkage can create enough mechanical energy to power an engine, and then have that mechanical energy converted to electrical energy to light four LEDs. The alcohol burner heat source is secured in a recessed well on the finished wooden base for safety. Engine can be run repeatedly for a memorable lesson in thermodynamics. 7" wide, 3.5" deep, 3.25" high.
