This rotary engine constructed by Latheman’s Crazy Machines puts Nikola Tesla’s reciprocating thermo-magnetic motor design into practice.
The motor Tesla developed consists of a movable rider composed of a soft magnetic material pulled in one direction by a spring and the other by a magnet. The magnet pulls the rider to a position in which it can be heated by a flame, as you can see in the video.
The operation of the motor relies upon the Curie temperature, a temperature at which the rider is no longer attracted to the magnet. The spring pulls the rider away from the flame and, as it cools, it regains its magnetic properties and is again attracted to the magnet, a process that repeats itself over and over again.
