Hi, I hijack this subject to talk about nuclear isomers and Hydroton (Ed Storms) theor.
Abd in another thread interpreted the hydroton mechanism for producing energy before the fusion, as the transition toward lower energy nuclear isomer (he find it improbable). My intuition from the mass of experiments, is that LENR is the opposite of hot fusion, in that there is a strong preference for low activity outcome. Hot fusion, and many LENr theories assume the the coulomb barier, the weak barrier, is overcome by high energy. The result is that the outcome accumulate the energy of a fusion plus the energy of the barier, leading to high energy gammas, high momentum particles ejections, excited nuclei which desexcitate violently. Some other theories imagine tunnelling to avoid the coulomb/weak barier, but anyway the fusion alon lead to a similar unobserved results, high energy outcome. This is why I find interesting the idea of Ed Storms that the collectivity of nuclei emit energy slowly, like a leak, before an effective fusion which bring the collectivity to a normal energy state, of low excitation. For me it is only possible if the collectivity of nuclei cool down like water in deep cold space, or like in a fridge. First requirement is that the collectivity of nuclei are interacting in a new way, of this state will be the normal bottom state of individual nuclei. Maybe this requires mosbauer variants (like cook) or magnetism, or LAH/DiscreteBreather... who knows. the second requirement is something to pump energy out of the "water". One possibility is that strange quantum effects prevent x-rays to enter the hydroton, and let it leak (dunno if it is possible). Another is that there is a heat pump at quantum scale, why not discrete breather or things like that, why not exploiting unknown interactions like mosbauer variants... the first question, is if it is possible to have a coherent collectivity of nuclei which, like ice, have a lower energy than usual incoherent collectivity of nuclei. the second is if there is a possible "heat pump" that can do the job, like DB/LAH, or simply dark sky cooling (focusing energy interface toward a cold space/bandwidth , preventing local heat/radiation to interfere) PS: I don't want fringe answers (too easy to invent a new idea), but something based on material science and QM. That is the rule of my game ;-)
