No, she isn't. She says she does not understand McKubre's papers. Anyone who does not understand those papers does not understand calorimetry, because McKubre's calorimetry is relatively simple and easy to understand, by design, as McKubre himself explains in his papers.
Yes, there were hundreds of working reactors. They were run thousands of times, as the paper from He shows. They were all small laboratory bench-top devices. Larger reactors cannot be constructed. No one knows how to effectively control the reaction so it cannot be scaled up. Some progress in control and reproducibility has been made, as you see in the papers by McKubre and the ENEA.
There are not now, today, hundreds of reactors because -- as I said before -- the researchers are dead from old age. Dead people do not conduct experiments.
(Note that when I say "as you see" I mean you have to actually read the papers. You have not read the papers, and I doubt you will. If you had read anything, you wouldn't need me to spoon-feed you the above information. Anyone familiar with the research knows what I just wrote.)
My point still stands Jed. Despite your claim of thousands of successful tests we are yet to see one working reactor.
Can you please provide me a link to McKubre's paper. I will read it and then we'll discuss.
