Again, we did not answer in silence here either. Rossi's position has always been that the COP can be determined despite what was behind the wall. And he is right!
No, he isn't right. You can't even measure it knowing what is in the fake customer site. You have to measure steam quality, and there was no means of doing that. There were no instruments capable of it.
However, using a common sense estimate of what the pressure had to be, it was easy to see there was only water, not steam, and the flow rate was far lower than claimed, so there was no excess heat. That is only a crude estimate. As Smith pointed out, if Rossi had wanted to measure the enthalpy, he could have easily done so.
We did not answer in silence. It was pointed out that Smith apparently didn't even read the manual, which states that the actual maximum pump rate is several times the rated output.
That's nuts. No manufacturer ever underrates a pump, or any other product. If the pump can produce 6 gpm under any circumstances, they always rate it at 6 gpm. Even if that can only happen in ideal circumstances. I have purchased and used many pumps. They never work as well as the rated capacity. I have also written many manuals. The manual and the face plate never understate capacity. They often disagree, because the tech writer is the last to know, and the manual is squared away before the product is ready. Where the manual and face plate differ, the face plate is right. There would be serious legal consequences if it understated or overstated ideal capacity, power consumption, or anything else.
Nobody but nobody would claim the pump(s) can only produce 3 gpm when they can actually produce 6 gpm.
