Although most of the criticisms have been made elsewhere, Krivit has helpfully (for those critical of Rossi’s claims, at least) provided a clearinghouse for them.
The arguments supporting Krivit’s claim that the E-Cat achieves an energy gain of only one or two times input power are contained in the appendices to the main report. Krivit does not deny the possibility of achieving excess heat from nickel-hydrogen reactions and emphasizes that he has covered the field on various occasions before.
Regarding the charge, made more or less openly by both Andrea Rossi and Daniele Passerini (link is in Italian), that Krivit is in cahoots with Francesco Piantelli, Krivit does not address it directly, but says in his report: “I have not seen Piantelli for a few years, but I have been in touch with him recently to confirm the history of his research.”
Perhaps most interesting, because it’s news, is the last section of Krivit’s report, which confirms Rossi’s meeting with members of NASA’s Marshall Space Flight Center in Huntsville, Alabama, and identifies Michael A. Nelson as the man who arranged the meeting. According to Nelson, as reported by Krivit, Rossi made no demonstration and no agreement had yet been made between Rossi and NASA, but NASA is interested in testing Rossi’s device as long as the government doesn’t have to foot the bill. Nelson is eager to find out the truth about Rossi’s device, whatever it may be. These words from him are worth quoting here:
Rossi has brought a lot of attention to the field. Any researchers who have a legitimate claim are going to benefit from this.
