- A unique demonstration tool of an alternate energy source
- Demonstrate to students the principle of the expansion and contraction of water vapor to power a model airplane propeller
- The Stirling engine is designed to operate with either hot or cold water
- To operate the Stirling engine, place on top of a mug of boiling water
- A cylinder on the bottom of the engine reacts to the vapor of the heated water by allowing the water from the hot side of the cylinder to the cold side
- The resulting expansion/contraction of the gases in the cylinder causes a rubber diaphragm to react and in turn move the propeller
- Properly designed Stirling engines have two power pulses per revolution, making them a very smooth engine to operate
- Engine is fully assembled
- Recommended for grades 7 and up
