Carnot is for heat engines. So the maximum efficiency of converting a heat differential into kinetic energy.

This is converting electricity into kinetic energy and vice versa. So it'd be the product of those two maximum efficiencies, whatever they are.

Where do you get that from? The article definitely seems to me to be describing a heat engine.
