Thanks Jay, yes that is a good analogy.

Of course spacecraft radiators are a bit more complex. In particular, they
generally need to transfer power and/or fluids across the rotary bearing.
These mechanisms are quite costly.

Hmm, I wonder if anybody has thought of using microwaves to transmit power
across rotating structures.
