Stirling Engine • A unique demonstration tool of an alternate energy source
DC Motor Kit
• Comes with instruction booklet • Requires one AA battery ( not included )
• 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 Stock No 76-0538 Mfr No MM-1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $WEB
