My 3 W figure is designed to be actual energy used, and applies equally
to the electrical and mechanical systems. Adding in the inefficiencies
won't change the basic energy requirement. A thermoelectric system by
the way would have no moving parts, apart from the cheap fan.

The problem being global warming. As an engineer and scientist, I'll
take nuclear over any currently offered alternatives.

I am illustrating the concepts involved with real numbers - as you
asked. You have seen the working, do your own numbers now, or put up
some other cases and I'll work them into a simple spreadsheet or something.
