This is important! Rossi is saying that on Monday, they will upload a report by Levi et al. describing a self-sustaining run. This is the Holy Grail of cold fusion: a self-sustaining device that produces commercially useful levels of power.
People may have some doubts about Rossi's credibility, but I think there is no reason to doubt Levi and the others. If they say they saw the thing self-sustain, I for one will believe it. As I said before, this development is not all that surprising. There is plenty of supporting evidence from other experiments. There is no reason to doubt that a scaled up machine can be built. It is a little surprising that the breakthrough came with Ni-H. The temperatures and power density with Ni-H have usually been low in the past, as far as I know. Pd-D has achieved greater power density. - Jed
