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.

If you get a good rolling boil, you shouldn’t need to stir macaroni.
Tho it is a bit of a waste of energy, since a rolling boil is more than you need to cook pasta.
I remember my high school science teacher saying that once you reach boiling point any extra energy input is wasted.
That doesn’t seem to be true in practice though.
I guess in a full rolling boil more of the water is at boiling point rather than just the layer at the bottom.
