From: Jed Rothwell Big difference. There is no evidence that hydrogen fusion is involved in Rossi.
There is no evidence it isn't. No one has checked, as far as I know. Really? The highest quality testing which was performed in Bologna was radiation monitoring. Top notch instrumentation and technique. Why is the lack of radiation above background "no evidence" for the proposition that hydrogen fusion cannot be involved? Sorry for the double negative but it is pretty obvious that radiation was checked for, and that radiation is a relic of fusion, and none was observed above background. In Pd-D fusion, gammas have been observed above background even in experiments in the one watt range - and this is claimed to be contributory evidence for fusion (along with transmutation). Rossi claimed many kilowatts of excess energy in January yet no radiation was observed, even through a gap in the shielding where the monitor was placed. The Swedes did isotopic analysis and found natural isotope ratios and no radioactivity. This is strong evidence against any kind of nuclear reaction having taken place. It bears repeating: There is no evidence that hydrogen fusion is involved in Rossi.
