Hmmm... tritium activity increasing in chilled acetone near the freeaing point of D2O. What could that mean? Was D2O present at all? It appears that acetone melts at ?94.8°C so this is not likely to involve the same "brittle mechanical failure" mechanism of explosive ice, or is it? At any rate, when hydrogen (or deuterium) bonds fail catastrophically in an explosive failure, atoms do get accelerated to keV energies, thus the x-rays seen in exploding-ice. One can interpret the implications of the Fateev experiments, cited earlier, in many ways to suit their personal agenda, but one cannot deny that x-rays do result from this mechanical failure. Indeed Bridgman showed the same thing with may types of brittle failure. The Fusor of Miley Hull etc. has demonstrated rather conclusively that head-on D fusion of the "warm" ICF variety requires a minimum of 10 keV per particle. Unlike Ed, I do not agree that this is necessarily the same as hot plasma fusion, even though the fusion products may be the same. There could just be an under-appreciated resonance at 10-25 keV range. BTW the rock-solid Fusor results of R. Hull seem to show that there is no net advantage, perhaps a nerative return of energy, of going much beyond 25 keV per particle in energy in the Fusor, so this is not "exactly" the same as hot fusion, even though the ash is the same, confusion of no. Is it possible that "bubble fusion" is not about bubble *collapse,* necessarily but about the pulling apart of hydrogen bonds in bubble *formation* at the point where the bonds normally would start to stiffen, due to decreasing temperature? IOW when a deuterium bond is at zero-C at ambient pressure, and that pressure is suddenly removed, prior to cavitation in the formation of the bubble; then the "effective temperature" drops signicantly for those bonds. The bonds will tend to realign to the new angle (the angle they assume in the solid, which is different than the bond-angle of the liquid), and the Casimir force will wrench some small proportion of bare deuterons away in a brittle mechanical failure. What happens next is anybody's guess. Of course, wouldn't it be delightful, for other reasons, to learn that there was some heavy water in the acetone. Some fringe observers might then claim that D2O is the active medium... but even if not... Wonder what happens when you get the acetone temperature down closer to the f.p.? They aren't telling, for whatever reason, but the thought surely crossed their collective minds during the experiment, since they already found positive results going lower... maybe Knuke knows what happens at lower temperatures, yet ?
