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.

I’ve thought long about this, specifically those devices that use the pizeo electric effect to move a fan.
Problem is that you need a temperature difference to make the effect go. But ideally I’m imagining a fish that swims around the pot converting heat to work.
