Jack,
One has to wonder about the credibility of an anonymous poster who claims to get excess heat in a Celani experiment, publishes no data, and instead of using Constantin wire as does Celani – he uses nickel. Or is the data and other details posted somewhere? At best - that makes it a Thermacore experiment, which actually gives it more credibility than Celani. But it should not be confused with Celani where the wire treatment is said to be critical. There is no doubt that Thermacore had about the same gain using nickel and also could not make it go higher than about COP ~1.5. From: Jack Cole me356 seems fairly certain about getting excess heat repeatedly in Celani type experiments (up to 1.5x). He does mention using 30ft of wire! Maybe that matters. https://www.lenr-forum.com/forum/index.php/Thread/2850-me356-Celani-Ni-Wire-replication/?pageNo=1 Andrew Hrischanovich also reports achieving 1.5x in Celani type experiments and notes higher pressure seemed to help ~10 bar. In personal communication, he indicates being unable to push it beyond that and is currently focused on TiH2. http://www.e-catworld.com/2016/02/05/tales-from-the-laboratory-of-experimental-physics-lenr-research-in-ukraine-and-russia-by-andrew-hrischanovich-alan-smith/ Of course as we have seen time and again, there is often something discovered which invalidates the results.
