I imagine it would have to be some sort of impractically large closed-loop steam system, probably running around the perimeter of the pot, with a rotating paddle inside. Not at all practical, but it would be neat.

There are things called stovetop fans that look like just a metal base with a fan attached to it, but they have a Peltier module or Stirling engine hidden inside. They use heat from the stove to turn the fan and blow warm air around the room. Should be able to make something using that trick that sticks down into a pot and stirs things. The thickness of the stuff being stirred will be the issue.
