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.
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 flame uses isopropyl alcohol.
Special thanks to Jan Ridders for sharing his original design and offering constant guidance and suggestions during the build.
