I wonder if it would not be better to do a simple comparison between cells... For that, one could build four cells (just to be certain): 2 exactly as Celani's; and 2 again exactly as Celani's, but without active wires. As you know, in the Celani's cells there are two wires: one active and another just for heating. With proper mounting, the four cells would have wires almost identical (size and initial resistance). Therefore, they could power them up in series (only the wires used for heating). In this case, all cells would receive the same amount of power and should show about the same internal and external temperatures. Unless of course, as many would expect (including me!), the active cells show excess heat. In this case, considering the amount of excess heat Celani saw (~12W of excess heat from 48W of input heat), it would be easy to spot the temperature differences and, therefore, prove that the excess heat came from some misterious reaction (LERN?) in the cells with an active wire in it.
By using two active and two inactive cells, one could rule out other factors if the inactive cells show the same internal and external temperatures and the active cells, at the same time, show significantly higher temperatures in accordance with Celani's colorimetric formulation. To avoid problems with pressure and gas composition, the cells could also be connected in series with tubes and receive the gases in series at the same time. Before power in, valves between cells (open during gas load) could be used to isolate then to avoid heat transfer via gas. I believe this approach is much easier and cheaper than flow calorimetry... Dear sceptics, could you see excess flaws in this approach? Alberto F. De Souza.
