While on the subject of high-Q coupling, trihydrogen should be mentioned.
The trihydrogen cation - [H3+] is one of the most abundant ions in the universe, far more abundant than H2, since it is stable in the interstellar medium. Therefore, due to its natural stability in extreme circumstance - trihydrogen can form the basis of a compelling model for one variety of LENR. In this type of LENR, which is one of perhaps a dozen possible energetic hydrogen reactions - nanocavities are present; and H3+ could be the active agent for gain within these cavities. Here is a visualization. http://www.youtube.com/watch?v=laSRGS8-BU4 The center ball would be a proton with both electrons, preferably in reduced orbitals, tightly bound. There is no need for full electron degeneracy in this model. Therefore it could have a higher probability than reactions requiring electron degeneracy, which is rare. The two protons on either end of the centered hydride - are normally oscillating and bound by electrostatic and magnetic bonds which can flip to one of two net spin polarities - ortho and para. These two alignments have different spin energies. What is not shown in the video is the cavity walls, where the proton, on its excursions away from the center of mass, encounters the near field of the metal containment structure. This would provide electrostatic attraction to the wall, and enhanced range of oscillation and also would disrupt the oscillation resonance. Very often, due to the delay and phase shift, a returning proton will encounter the other returning proton, within the electron smear of the tight orbitals, and will react in the known diproton reaction, due to strong force attraction. This is not an elastic collision but is technically "reversible fusion" since the protons are still protons after the encounter and Pauli exclusion statistics prevents anything more. This reaction provides for asymmetric spin alteration from low spin to high spin via mass conversion and by coupling of nuclear spin to the net magnon spin of the entire system, including the nickel containment. The result is anomalous heat via a sequential Lamb shift, happening at THz frequencies. This would be a mechanism which functions as an alternative or in parallel to ZPE conversion, which can also happen at the same time in the same circumstances. In neither case is "real" fusion required, yet in both cases, there can be an occasional nuclear reaction or transmutation as a side effect. The side effect would typically supply only a tiny fraction of the excess energy of the sequential Lamb shift so it can be ignored. Jones
