It means he could be using nickel and hydrogen and possibly Mg, so that inspection, if he ever allowed it, would reveal nothing but the components he's claiming. Except some kind of pressure vessel is needed to store the hydrogen as the heat dissociates it from the metal. The unit described in table 2 is about 3 times larger than Rossi might need for his fat cat demos. It stores 36 MJ at 450C, and produces 4 kW power output, weighs 40 kg total, and requires a 20 L pressure vessel. So to store the 12 MJ needed for the Oct 6 demo, a 7L vessel would be needed, and the total weight might be 13 kg. What this should make clear is that energy storage is a well-developed science, and that if Rossi wants to convince skeptics that he is *producing* energy, he will need clear evidence of energy output significantly and unambiguously greater than energy input, whether or not it seems feasible to internet observers that the input could be usefully stored. (Of course, to really remove all doubt, the output should exceed the total mass of the unit in the best chemical fuel, but one step at a time...)
