Steve, > But your question pertains more directly to the consumption of mass in exchange for energy...it would take a long, long time for the fuel to be consumed.
Not exactly what I was refering to, but close. The "devil is in the details" as they say .... Specifically what I am suggesting is that in any population of hydrogen there could concievably exist a small (PPM or less) previously undetected population of metastable isomers (a much smaller ratio that the deuterium content of sea water, for instance.) Even in CF, this possibility has never been ruled out, in either experiment or in QM theory that a population of metastable isomers does not exist and is responsible for the excess energy. These might or might not be the same as "natural" (i.e. solar-derived) hydrinos. The excess energy might come from either a higher cross-section for fusion, or a direct release of low energy x-rays or EUV. Jones
