A Working Stirling Engine

Here is a great time lapse video of a working stirling engine in action.

This Stirling Engine uses neodymium magnets in the displacer and slide piston to control the return stroke of the displacer. A third magnet above the displacer balances the forces to minimize friction in the glass cylinder.

Major components of this working stirling engine design.

  • All pistons are made of graphite.
  • The main cylinder is a Pyrex test tube.
  • Engine is machined in brass and aluminum.
  • The base is Corian.
  • The fuel source to produce the flame is isopropyl alcohol inside the burner device on the right hand side.
