Am important rough energy balance anyway. >Peter [snip] If all Ni isotopes react equally, and 2/3 of Ni is Ni-58, and we assume single proton fusion, then the primary reaction would be:
Ni-58 + H -> Cu-59 + 3.42 MeV which then decays rapidly via positron decay according to Cu-59 -> Ni-59 + e+ + neutrino + 4.8 MeV (however a considerable portion of this will be lost via neutrinos; say 1/2?). so the total reaction energy is 3.42 + 2.4 = 5.82 MeV / Ni-58. 2/3 *50000 kWh / 6 MeV = 1.2E23 Ni-58 reactions, which is 12 gm Ni-58, or about 18 gm Ni altogether (assuming the other isotopes all yield about the same amount of energy / atom). So quite within the realm of possibility. OTOH, if he had 300 gm of Ni, and 1/3 was converted to Cu, then that represents considerably more energy, and one has to wonder where it all went?
