Mark,
The first question that must be answered is: it the Ni-H phenomena Quantum Mechanical in nature, or is it Thermonuclear, on a reduced scale? There are some that still believe Ni-H is thermonuclear and in fact, Pd-D could be. In fact W-L theory tries hard not to be forced into making that decision, and has QM features - but if the defining detail of that theory involves neutrons, neutron capture - and subsequent weak-force reactions, just as are seen in traditional physics - then it is a thermonuclear theory. Theories that involve tunneling of protons in one form or another are QM based - if no neutron is involved. QM is normally too low in probability to account for much heat. But one aftermath of the development of the modern CPU by Intel and others is that QM tunneling (of electrons) can be engineer and optimized to occur at very high rates. A CPU operating a 2 GHz will have electrons tunneling in predictable fashion the high terahertz range. The CPU is a QM electron tunneling device operating at high probability. The CPU is a good model to use for proton tunneling - where instead of a small chip needing to shed 30 watts of heat (and not gainful) you have much more heat, and importantly it is anomalous due to the tunneling. If there is gain, then it must be defined. Without going into great detail on defining the gain for now, except to say that it comes from the mass of the proton, and it comes without much radiation or transmutation (some of each, but way too little to account for the gain), then it is easier to account for the quiescence phenomenon. Stated simply, quiescence involves "too much depletion" in the mass of the hydrogen so that the high level of probability of tunneling is reduced. This is where anything that relates to QM probability come in, and you have already found papers suggestive of a few of these factors. Rossi has designed a reactor where hydrogen is not circulated and it is likely that he could eliminate the problem with periodic dumping of H2 and reloading (every few hours) on a set schedule. There is evidence that DGT may be doing this already. Jones From: Mark Iverson-ZeroPoint If quiescence is a reality, and *if* it will require a scientific/QM understanding, the I don't think any amount of 'control engineering' is going to be much help. one will need to find out the cause of the quiescence, which is a physics problem. If the quiescence is of a reasonable periodic nature (i.e., repeatable), or if it gives you adequate 'warning' that it has started, then one could have 2 or 3 reactor cores inside, only one of which is 'running'. When it begins to go into quiescence, one then starts up one of the 'idle' cores. while shutting down the quiescent one. This is a brainless kind of solution, and wouldn't work if the quiescent core needs to be unassembled in order to make it 'ignite' again. If reactive capability can be reinstated by shocking it with a hi-V pulse or cycling H2 pressure, things like that, then it could be automated and done while in-situ. These are engineering problems, not scientific ones. -m
