No, that is not an issue. He wrapped the cell in insulation. This allowed him to lower the input power a great deal while maintaining the activation temperature. But he was not able to lower input to zero. He hoped to do that to eliminate all doubts about the calorimetry. His plan was to trigger the effect with a heater and then gradually back off all heater power. I do not know why this did not work. I did not discuss it with him. I heard that it did not work. If the effect is an artifact, that would be a reason for it not to work. By the way, the Cerron-Zeballos paper is here: http://lenr-canr.org/acrobat/CerronZebainvestigat.pdf I am well aware of it, and it is one of the reasons I have remained wary of Focardi. I have heard reports that Focardi improved his calorimetry and addressed this. But he has not published any papers describing this improved calorimetry as far as I know, so I cannot judge whether he addressed these problems. Other researchers I know who have visited him have told me is is uncooperative. I have never met him or talked with him. Regarding Ed Storms' analysis, it applies to all isoperibolic calorimeters where you measure the temperature at the cell wall, regardless of what is happening inside the cell. The reaction inside the cell could be liquid, gas, or even nuclear plasma. The problem occurs when there is a lag in heating different cell wall components, and when the cell wall heating is not uniform. In an electrolysis cell, Melvin Miles recommends measuring the temperature wall rather than in the fluid. This eliminates all doubts about mixing the fluid. As I said, he uses a copper cylinder around the cell to ensure a uniform temperature. In other words, from the inside you have layers: cathode, anode, electrolyte, cell wall, copper wall, temperature sensor, crumpled up aluminum foil, second wall, ambient room air. His calibrations show that temperature sensors located in different places around the copper stay within a very small range of one-another. Changes in ambient air temperature and currents of air have little effect on the temperature sensors. - Jed
