Hielscher Stirling 1 Assembled Model

The unusual Hielscher Hot Air Engine Stirling 1 has a flywheel in the shape of a propeller and its displacer cylinder is a thin-walled can made of tin. It can be fuelled either using a spirit burner or tea-light. The number of revolutions per minute will be lower when the engine is operated using a tea-light due to the lower temperature.
