Could this be used as an engine of some kind? The spinny thing giving off EM waves and those waves are caught by something like a solar sail?

Perhaps in reverse (which should be equivalent, since Maxwells laws are time reversible).. rather than having waves amplified by stealing energy from the cylinder, waves could amplify the rotation of the cylinder.
