To complicate matters, it must be mentioned that plasma electrolysis (glow discharge) with AC gain possibly be gainful, but we have been talking about low voltages in the Site's experiment. Here is a paper from Horace on discharge electrolysis
http://www.mtaonline.net/~hheffner/GlowExper.pdf From: Jeff Berkowitz And, by golly, here's another interesting note: the energy required to split water molecules by electrolysis is dramatically reduced in the presence of ... nickel borate. http://phys.org/news193055742.html That is only half the story and is probably disadvantageous for Site's borax nickel experiment, at least in the way it is being performed. Let me add, once again, that high efficiency in splitting water is counterproductive - STRONGLY counterproductive - when your aim is to increase the thermal rise in the electrolyte. The split gases carry away what would otherwise be thermal energy. This would be true to the extent that split gases are not recombined in situ. Recombination will not happen with DC power, as a general rule. The easiest way to recombine most of the split gases in situ, in an unpressurized cell, is with AC power. Done correctly, this will produce minimal net water-splitting and maximum thermal gain in the electrolyte. It helps to have recombining catalyst in the electrolyte, and nickel ions do exactly that. If the implications of Nocera were to be correct - then recombining gases which were split gainfully (OU) would then add anomalous heat, and that result would violate CoE unless there is a nuclear gain of some kind. The implication is that there is a nuclear (LENR) gain.
