G'day
Now I am really confused.
Perhaps someone can explain to me in words of one syllable why a variable
speed 12v electric motor, in the place of a water pump does not free up
power?
Sure the electricity has to come from the generator/alternator/battery but I
know that my car goes just as well with the lights on as it does with them
off.

The electric waterpump is constantly running and needs power which is
supplied by the engine. So you would not gain much if any. The only
advantage may be a better design and thus more efficient.
The fan is a different story as it not running most of the time.
