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.
