Surely you mean rectifying the stepped-down 100V audio line input to the hotel room unit? Transferring the electricity originally derived from the mains downstairs, converted to audio and sent to the hotel room clock up the PA distribution wiring?

I can't see the BBC being so generous as to provide sufficient field strength to overcome a diode voltage drop for the abstraction of free electricity!
