Many have pointed not just to the cold fusion production of He4, but critically, to the production of quantities of He4 that explain the measured heat.
If these results are correct, the implications for Mills's theory seem to be either the energy produced by He4 fusion events swamps the energy produced by the antecedent hydrino production, or Mills is wrong. The question therefore arises (again, assuming the He4 vs heat measurements are correct): "What is the expected ratio of energy produced by He4 fusion to the energy from antecedent hydrino production?"
