(This is peripheral to the point, but anyway...) I don't agree. If it runs without any input, then the fact that it produces substantial output power can be identified without instruments. You can tell if a 1.5 kW space heater is working without instruments, just as you can tell if firewood is burning or not without a thermometer. Now, to judge whether it exceeds chemical energy requires instruments only if it exceeds it narrowly, by a factor of 10 or less maybe. But he's claiming a factor of a million or so, so if he produced 100 times more than chemical, that would be easy to identify without instruments. He could use the heat to heat a big swimming pool, or a series of tanker trucks, or something. If he takes the water from ambient to boiling, and you estimate the volume, then no instruments are needed. Or if he used the heat to produce electricity, and then used the electricity to do some work, like lifting a large truck, or to power an electric car, then instruments would not be needed to estimate the energy to within a factor of 100. Of course, Rossi is nowhere near that level, and it would take some time, so for the demos he is doing, where the claimed output barely exceeds what he claims is feasible chemically (taking only a fraction of the weight of the ecat), then yes, instruments are needed, especially since he also has to provide input either continuously or periodically. But to me, his need for instruments to demonstrate such a dramatic effect, makes it much less credible.

If Rossi's reactions depends on new physics to produce heat from nickel and hydrogen, then so be it. My objection in this instance was not that. It was that the observations he is basing the claim on depend on *other* implausibilities. The new physics is presumably in the H-Ni, but that shouldn't change the way water gets heated by the hot conduits it flows through. Those heating elements still have to get hot, and the way the heat flows through the brass or steel pipes is surely not affected by Rossi's new H-Ni physics. Heat is still heat, surely. What if the temperature read 90C at atmospheric pressure, and he claimed complete vaporization. That would be implausible because water boils at 100C at atmospheric pressure. Would you then say that this is a new phenomenon, and so we don't know what temperature water boils at when the heat comes from a Rossi reaction? Therefore we can't say that it's implausible? Would you say that?
