Description
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.
