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.

Nah it means, once the water is at a rolling boil, turning the heat up more wont increase the heat of the water, just the rate at which its becoming steam.
Of course, the heat will dissipate if you turn it off.
