Eric, You make a good point. As a selfdeclared (precision) measurement addict , let me comment: 1) Calorimetry, especially with small effects, is a central issue. I do not know a lot about that, but manageble by careful analysis The possible errors even Rossi et al made in high-power contexts with COP>>1, makes my head scratch. How could this possibly be?
2) Small effects with small (+/- 1watt) systems are difficult to measure,agreed, but manageable with careful measurement techniques. Maybe Rossi put some hope in National Instruments, because this -ahem- measurement thing was all over his head. He is the guy for the big things, not for watching ants doing their walk. But the NI guys do not know a lot about the intricacies of physical effects, which they eventually measure to six points behind the comma, not knowing what they just measured a second ago. NI-management is not a lot of help here also. Those are basically the know-nothings, who see this as a commercial issue. So to call NI to the resuce of Rossi as the competents, is a pledge of a bunch of incompetents in the first place. It is like Apple accusing why Your girlfriend told you she leaves, because she was using an iphone. But it seems we did not yet reach the lowest(highest?) level of delusion. 3) I always wondered, why , as You mention, nobody monitors the development of the resisitivity of the base-reactant --day Ni or Ni-Cu over temperature-time- H-loading, which should vary significantly BEFORE any reaction takes place! Eg constantan, which is 55%Cu 44%Ni, 1%Mn has an extremely well known R-T coefficient. This is a reference. If this changes via H-loading, T, pressure and such, this would be significant! Just have a careful look, and know what You are doing! 4) calorimetrry maybe a difficult issue when small quantities are involved, but not insurmountable. Micro-Kelvins can be measured eg during phase-changes of metals, as I managed to contribute in my professional carreer. So what exactly is the solution to the problem? a) have a good grasp of Your effect b) have a good understanding of how you isolate the effect out of noise and side-effects. Quite basic, right?

High resistivity is not necessarily an issue, per se. In the Pd/D electrolysis experiments, as the palladium is loaded with deuterium, the resistivity goes up. Often the target loading is 0.95 or higher, so it seems likely that there is a lot of resistivity in a good run in such experiments. I think a common belief is that it is the *flux* of deuterium that is important in those experiments; whether the deuterium is entering the substrate or leaving it does not matter. Assuming a parallel can be drawn with Ni/H electrolysis, an AC current might not be undesirable in itself, unless it somehow messes up some other important variable. Eric
