An accelerated weak-force interaction - as odd as this possibility may sound - could be of interest to those trying to find and optimize what is in fact "real" nuclear energy - but which may have been classified as LENR or Millsean - formerly.
This is rather ironic but the radioactive isotope of potassium, 40 K, has been tossed around for decades as being a prime hidden candidate for accelerated decay (assuming such is possible) and "free" energy. It does turn up prominently in experiments where energy gain is claimed. Curiously the patent in question does not mention the weak force or accelerated decay of potassium. Nor does it mention the Mills connection but it does supply some interesting thinking about a procedure to implement EC. Too bad that the IP (apparently) went nowhere. BTW - Excess energy of 40K potassium is 33.5 MeV per nucleon but the natural abundance of the rare isotope is only one part in 10,000 in natural ore, so the potential energy available - if it were not for the long half-life, is about a pound of KOH as the equal of a ton of coal. Not bad especially if that excess energy could be used to spit water, which is the interesting thing about lye - it has always been known to be the best electrolyte available. One idea for ultra efficient electrolysis would be to use RF instead of DC at the NMR frequency (a few MHz dependent on an applied magnetic field).
