Good point Robin. There could have been accumulating H2/O2 bubble formation that suddenly recombined (burned) to give the big jump in temperature. Jack has a neat Android based controller that lets him collect data by cell phone. I think we will be hearing more on his progress as time goes on.
The real problem with simple electrolysis as a way of looking for thermal gain which is due to such things as Ni-H LENR - is that without a recombiner, you have two contradictory or self-cancelling influences... in the sense that high efficiency in water-splitting efficiency actually carries away significant amounts of heat from the cell, and makes the cell cooler than it otherwise would be. Thus, an inefficient cell for water-splitting in terms of liters of gas per minute, can show more thermal rise than an efficient cell for water-splitting unless the heat of the gas which bubbles off is accounted for. It usually is not. This is most problematic since thermal gain in the electrolyte should be an easy and reliable way to document the anomalous nickel-hydrogen reaction -IF- all the heat could be retained. A recombiner usually requires platinum, and thus is not seen too often in low-cost experiments. But there can be a work around in trying to maintain hydrogen on the cathode for as long as possible. However, that means manipulating the voltage to a minimum level, but catch-22 low voltage electrolysis is known to cool a cell on its own. More on this later: a milliwatt UV laser could be the answer. UV lasers are available for almost nothing these days, and using one could be a way to safely employ a sealed cell in which almost no extra energy from the laser recombines the gas a few times per second. -----Original Message----- From: mix...@bigpond.com Hi, At 11350 seconds it suddenly flattens off. The curve after the jump appears to be a continuation of the curve before 11350 seconds. This gives me the impression that something changed at about 11350 seconds which was restored during the jump. Perhaps something like a change in conductivity &/or bubble formation at 11350 seconds that released just before the jump? >Here is the run overnight with the graphite anode replacing the stainless >steel. That temperature jump about half way through seems intriguing. > I've never seen it do that before. It occurred over 90 seconds. http://www.lenr-coldfusion.com/wp-content/uploads/2013/06/6-15-13.png
