With the previous research findings of significant excess heating for approximately 21 hours, the issue was raised of chemical reactions possibly accounting for the reaction. The attempt to repeat the results empirically ruled out the likelihood of this with no excess heating demonstrated during that run. It is possible that the chemical reaction used to produce the hydrogen was in some way inhibited as evidenced by only a small amount of hydrogen occasionally being detected outside of the cell with the gas detector. With that possibility in mind, calculations were performed to examine the possibility of chemical reactions accounting for the excess heat. In short, it is not possible for chemical reactions to account for the heat.
If we take the entire internal volume of the cell (27.8 ml) and filled the entire volume with lithium hydroxide, we would get 1.69 moles of LiOH. Therefore, if all of the hydrogen contained in that amount of LiOH was liberated and burned (.85 moles of H2), we get 121.5 kJ (33.75 Whr of energy). This yields a maximum average output of 1.67 watts over the 21 hour period. In actuality, the amount of LiOH was conservatively 13 times less than used for these calculations giving 2.6 Whr of energy potential. We can safely rule out chemical reactions as being the source of the temperature difference. Feel free to check my calculations (cell internal volume of .25″ by 3″).
With the failed replication attempt, the concern about having only one end sealed during the calibration run as being a source of the difference was ruled out. The last thing to consider is whether there was some kind of systematic variable that was introduced when the cell was filled and returned to the tube furnace. Although it is unclear what that could have been, it is safer to assume it was the case until it can be ruled out through replication. In order to help rule out this possibility, an additional temperature sensor will be placed on top of the tube furnace providing another measurement that would be less effected by the precise placement of the reactor tube.
Three new cells have been constructed and are presently drying. Tomorrow will commence the calibration run for the next experiment, followed by the active experimental run on Monday (if all goes according to plan).
