I dunno, shouldn't be too much at all for Rossi to do; just a little of his special nickel fuel which would likely cost him a buck or two plus his time.Really, how much could it possibly cost to duplicate his experiment or create a LERN / eCat to test?
Really, how much?
For someone else? Gotta be really tough. Only been done by a few people at all... Mostly working for NASA, who of course is part of the USGov, who is of course under control of the Oil lobby... So let's not go down that route either.
