If you already have something rotating, why worry about any funny
transmissions.  Just create a magnetic field with a permanent or
electromagnet, mount some sort of coil on the rotating device, and
presto, you have an alternator.  The real power source is whatever
is doing the spinning.

I am coming in late, so I may well have missed something mentioned
earlier.

In this particular case, IIRC it spins too slow and needs too much
power for that the be practical.

A rotating transformer is the best answer in this case.  It's just
like any other transformer, except the primary and secondary can
rotate relative to each other.  Standard, off-the-shelf technology.

Try a search for "Propeller clocks"  they much power a spinning led bar
