Eric, thanks for the reference, That is exactly the point. As far as I can remember there are similar reports from eg Piantelli and others. What is missing is the conclusions in a wider context.
Which actually should be intuitively plausible: If a LENR-reaction starts, it produces A LOT of energy at a certain spot. My back-of the napkin estimates go in the order of magnitude of from 1000 to 10k base-material-atoms involved. Remember: 1k Ni-Atoms are a cube of approx 5nm^3. This zone heats up in a sub-microsecond-scale, and most probably melts or even explodes, ie releases local energy via a gaseous phase, the rest simply melting and possibly/probably losing its capability to start up another reaction, because it is structurally 'kaput'. Most of the evidence for LENR comes from quite low-key energy release, which must have a reason. My guess is, that these low-key reactions as maybe the MIT experiments do NOT cause melting or even explosions. We have a problem here: such low-key reactions are commercially uninteresting. So there is a need to prop up this meager evidence, and make a midge -at least in its current state- appear like an elephant. Decent, humble scientifically oriented minds consider that, and are not distracted by possible billions. So I listen more to the humble side , and not subjects or entities driven by an illusion of grandeur and big profit. It is enough that we have those artists in the financial business. No need to have them in the scientific/technological sector also.

I just happened upon a writeup by Stan Szpak, from SPAWAR, and others, concerning the PdD co-deposition process he pioneered, in which palladium is electroplated on a gold or copper or similar base. The SPAWAR video I have referred to elsewhere, which shows a number of bright hot spots rapidly appearing and disappearing against a red and blue background, is of one of these assemblies. What the authors have to say about it sounds similar to what Guenter guessed might be going on, where a small region destructively melts, or, in their words, explodes: The ‘hot spots’ observed in the infrared imaging experiments are suggestive of ‘miniexplosions’ (Figure 1b). To verify this, the Ag electrode on a piezoelectric transducer was used as the substrate for the Pd/D co-deposition. If a mini-explosion occurred, the resulting shock wave would compress the crystal. The shock wave would be followed by a heat pulse that would cause the crystal to expand. In these experiments, sharp downward spikes followed by broader upward spikes were observed in the piezoelectric crystal response. The downward spikes were indicative of crystal compression while the broader upward spikes are attributed to the heat pulse and the consequent crystal expansion following the explosion. >http://lenr-canr.org/acrobat/SzpakSlenrresear.pdf So there may be no reason to try to think up a nuclear active environment that is long-lived; it is possible that the NAE (if things can be generalized, here) typically explodes and goes away, with the reaction continuing on elsewhere in the substrate.
