Electric Generator
This belt-driven generator may be used with our Steam Engine (63030-00 ). Operating at approximately 1500 rpm, the generator will produce enough electricity to light the included 3.8 volt bulb. The unit is mounted on a metal base (7.6×11.4 cm) and has a V-grooved pulley for the drive belt.

The Stirling Design External Combustion Engine
Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.
