The little Stirling engine that could—without fuel. Simply place the engine over a cup of hot coffee or water and watch it go. To reverse engine’s direction, use ice water. Made of durable stainless steel, this stylish and affordable low-temperature differential unit demonstrates how heat engines convert heat energy into mechanical work. A classic demonstration of thermodynamics for middle school. Overall height, about 5-3/4”. Includes instructions; hot and cold source and cup are needed but not supplied.

Heat source should not exceed 100° C and cold source should not be below −20° C.

Avoid rough handling. This is a delicate instrument and the connections between the flywheel and pistons can be damaged. Always hold and handle by the base only to protect the delicate pieces. Item ships in a sturdy box that may be used for storage.

To ensure that the engine works well, perform the following 2 steps before each experiment:

    1. Rotate the flywheel by hand. The flywheel, connecting rods, and pistons should move freely and without resistance.
    2. Check that the connecting rods are properly seated. Linkages to the piston should move freely.

This engine is precision-manufactured; no special lubrication is required.

Flywheel diameter, 3-1/2” (9 cm)
Displacement cylinder diameter, 3-1/2” (9 cm)
Unit height, about 5-3/4” (14.5 cm)
