Check the listing for details. Nano Fin Stirling Engine. Condition: New. Listed at 134.75 USD. This engine is a gamma, with a displacer inside the main chamber and power cylinder connected to it by a transfer tube. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small power piston which in turn drives the flywheel.
