Curie-effect heat engine
The rotor is a circle of magnetic material. A magnet is fixed next to it. The rotor in one place, locally, is heated to Curie temperature, as a consequence of which the magnetic coupling temporarily disappears and the rotor-stator circuit is out of a stable position.
The rotor shifts, the cold part of the rotor is moved. As the rotor rotates, the heated parts cool down and come to a heating point with a temperature below the Curie point. The whole cycle repeats.
