Let me refine the previous posting with this reworded and conditional paragraph, not that it will be any less provocative to either camp:
*Given that both hydino-tech and LENR may involve QM reactions of hydrogen within the confines of a host element (i.e. the "energy hole"), if either technology is proved to be fully reproducible leading to a robust on-demand device (and especially if both are headed that way) - then: it follows (from this POV) that they will involve (as a 'sine qua non') differing versions of the same underlying quantum phenomenon. Specifically this predecessor state will involve "factional ground states" of hydrogen, as predicted by Robert Carroll, which are either temporary or transient.* Footnote: "Arcturus By Dawn" by Robert R. Carroll, where the fractional quantum hypothesis first appeared, was once available online, but in checking - the hosting site is no longer operational. This is mentioned only to counter the assertion that Mills 'discovered' and/or invented this state. The actual discovery of the heat anomaly "hot hydrogen" in modern times was likely "Langmuir's torch." Anyway, the full process might also involve the Casimir or similar force (ZPE) within a metal matrix or catalytic energy hole, which serves as an intermediary pressure force to accomplish the "factional ground state," which precedes LENR; but unlike Mills' CQM - there is no assertion that the fractional state be stable over extended periods of time. FWIW - The probabilities which I would assign to the various outcomes: 1) Probability of excess heat and transmutation in LENR - 100% 2) Probability of excess heat in hydrino tech - 100% 3) Probability of getting 'on demand' excess heat, for a time frame of years - without significant radioactivity in LENR: 10% 4) Probability of getting 'on demand' excess heat for a time frame of years - without significant radioactivity from hydrinos 90% or more. SIDE NOTE: I believe that eventually, even in the hydrino situation there will be some transmutation and trace radioactivity - if only "to balance the local-extropy books". The laws of thermodynamics may stretch and distort but there will be an eventual source of energy, unless ZPE supplies it all. However, since there is less chance of free neutrons or tritium, with hydrinos, then any radioactivity will likely be less toxic (to non-toxic) and may involve single proton transmutations, which would be impossible without a deeply redundant hydrino (acting as a near neutral particle). Such reactions include: sodium to magnesium 23Na --> 24Mg - or argon to potassium, 39Ar --> 40K (which is mildly radioactive) -or potassium to calcium, 39K -> 40Ca. If the above were true, and recent developments indicate it could be true, then it is almost certain that Mills has seen the radioactive signature of 40K in his old experiments, possibly after many months of operation - and yet failed to publicly acknowledge this fact because he fears the "taint" of cold fusion. Now that is ironic, since as of today the tables may be reversed in the perception of many. It can be noted that BLP seems to have now abandoned potassium, which is one of the most active catalyst elements - in favor of sodium - which was not even acknowledged as active for the first 12 years of experiments... and this curious switch away from a more active catalyst to a less active one could relate solely to the issue of radioactivity (after extended time periods of operation with potassium). As mentioned, the sodium to magnesium "QM balancing act" 23Na --> 24Mg would not leave much of a long-term signature, especially if the hydrino was depleted of energy, due to shrinkage. That one may be a natural phenomenon as well, in that certain land-locked bodies of water have anomalously high Mg levels together with corresponding depletions of Na, leading to a hypothesis that solar hydrinos have accumulated in those locales over millions of years.
