All of these are in some way heat engines

Yeah but those heat engines don't rely on spinning things inside a magnetic field. Heat on one side, less heat on the other side, and you have current. No motors.

even photovoltaics are heat engines in broad definition

We're all heat engines on this blessed day if you broaden the definition enough.
