For to record ... and to correct potential disinformation. Excess heat as seen recently in Celani/Technova etc. is NOT simply a surface morphology effect, according to Ahern's EPRI report.
Rather, excess heat depends on both nano-geometry and the proper alloy being found together in the same powder. Unfortunately, EPRI have not yet published this report, but the experiments showed clearly that identical nano-geometry, in a variety of metal powders, have massively different thermal effects, dependent on the alloy. The original Copper-Nickel alloy which inspired Celani to do this recent work came from Ahern, and showed the excellent predicted results, much better than palladium, which corroborated the Romanowski paper. That paper was based on simulation, not experiment; and Ahern's work offered the first important corroboration. He chose the alloy (which was supplied by Ames Labs) specifically from the Romanowski data (details of which Celani curiously misquoted in his paper). BTW - with titanium-nickel alloys (both metals implicated in prior LENR experiments) - there was NO excess heat, despite having good nano-features. That pretty much tells you that it is completely incorrect to label this as a surface morphology effect only. Pure nano-nickel is poor, pure nano-palladium is poor but an alloy of 90% Pd and 10% Ni is excellent (though not as good as the Cu-Ni alloys). The differences are not small. For excess heating, according to Ahern - you must have the 2-12 nm surface features and you must ALSO have the proper spillover alloy, which Romanowski essentially nailed. Hopefully EPRI will publish the study soon. Jones
