This proposed experiment is based on a minority viewpoint, in the interpretation of Dennis Craven's NI-Week demonstration, which after due consideration of the past 24 years of LENR, stands out to me as the most important experiment since 1989. Your assessment may vary, but the pluses of it are: that it is simple, understated, essentially unpowered, solid state, robust, long-running, well-constructed, and the error possibilities are greatly reduced.
IOW it is "elegant" to the extreme. The highest compliment that can be leveled at any breakthrough experiment in LENR is "elegance." However, I cannot really label the underlying M.O for this thermal gain as the "Cravens effect" since he is on record as favoring a nuclear explanation, so for now my version is being called the SPADEX effect for "superparamagnetic deuterium exchange"... to be explained in following postings. To backup a bit, the H/D exchange reaction is similar to a form of phase-change, and is a preferential reordering of a loaded metal matrix, where the two hydrogen isotopes play musical chairs at a rather phenomenal rate. The H/D exchange reaction can be described in the usual one-way form as chemical and conservative; or in this interpretation as a sequential thermal anomaly which is continuously being "reset" via nanomagnetism and the zero point field. The H/D exchange reaction is surprisingly energetic but is chemical - non-nuclear. So the first question is how can magnetism change the preferential ordering of a metal matrix where D has already replaced H for net chemical gain? This would be necessary if the energetic effect is to be made sequential and cumulative over time- and not a one-way affair. The second question is where does the reset energy come from. When we look at the spin, magnetic moment and NMR properties of the two isotopes, H & D - there is an enormous difference. Magnetic moment alone is triple for protons over deuterons and NMR frequency variation is even more lopsided. In short, the magnetic variation is so extreme between the two isotopes that the small preference for deuterium in the chemical exchange reaction is easily modulated (to the extent the near-field oscillates), which dynamic effect is felt more by protons than by deuterons. It can be noted that the B-field of samarium-cobalt can be .4 T at one micron, but at 10 nm spacing - the effect on protons could be significantly higher (if inverse square holds as expected). A magnetic Casimir force will provide that "free" oscillation in the context of a balance between superparamagnetism and superferromagnetism. In short, this may be the key to understanding the H/D exchange reaction as a sequential route to thermal gain in the Cravens NI-Week experiment. An actual self-powered experiment will be presented in the next post on this subject - which is open-source to the extent that anyone can order the parts and try it, thanks more to Dennis than to me. Only a self-powered experiment means anything these days, yet few design for it from the start, and AFAIK, it has not yet been achieved. Estimate of the out-of-picket cost is about one-large, as they say in Vegas or Joisey... and it is a crap-shot, but isn't all of life? Jones
