I think it's valuable to approach this topic as would a stage magician - just recall how far this sort of keen observational common sense got Randi; you don't need a whole lot of physics, but you do need a "jaundiced eye". Rossi is not renowned for his honesty, after all, and therefore one has to be prepared to fight fire with fire, but without devolving into some hopelessly crabby sceptic. I realise that discussing the mechanics of a scam may be distasteful to some purists, but hey, there's a lot of money involved here, and we are all grown-ups.
Below we're discussing the input hoax. As for the output hoax, I've run across a second possibility (my first was infrared lasers). Those long "resistors" could serve double duty as RF receiving antennae. Same principle as the lasers, but just a different frequency. And note that all this was done inside Rossi's own facility. Note further that, according to Randi, scientists are the most easily-fooled audience of all. Just ask Geller and Taylor.

That's "small". A battery would need to supply (say, conservatively) 500 W for 116 hours, or 200 MJ. Lithium batteries are about 2 MJ/Kg, so that's 100 Kg of battery. I agree that's unlikely but don;t have enough information to make the call.

A power meter looking at wall power is blind to any internal power source in the box that directly supplies the device with additional power. What sort of internal power source? A generator? That would noisy and obvious. A battery? That would run out before 5 days elapse. Or, if Rossi has developed such a battery, it is an important discovery in its own right. A hidden wire? It would have to be a fairly large wire, to carry 500 to 800 W. They would see it. Do you have anything else in mind? - Jed
