...agreed, not a co$t-effective replacement today, but when electric water pumps eventually become more common, under ECU control, it would certainly be more energy efficient to modulate total flow and use energy pumping coolant around only when you really have to.

...instead of "pumping" all the time and then apply "throttling" on top of that.
