I'm looking for an electrical coupling to provide 120VAC
to equipment on a rotating platform. The platform can
only turn one way, so it can't have wires up the hub.

Is there a commercial product out there, and if so, what
is it called? None of the electrical places I talked to
knew of anything like this...
