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
