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.

Made my own stir plate once with a computer fan, magnets, and a potentiometer. I am sure they come with heat if needed. They can come with extremely large stirring bars.
