There is a possible cross-connection between the Mizuno breakthrough and the Holmlid technique for dense hydrogen conversion into energy, as practiced by Norront: i.e. "annihilation technology".
Basically both techniques could involve three basic steps: a spillover catalyst, dense hydrogen accumulation, and a photon-pumped SP (surface plasmon) activity in the substrate (or laser irradiation). The Mizuno operative mechanism could be annihilation instead of fusion, since the details favor that route - pending the documentation of adequate helium which would change things. The detail of interest is that protium works as well or better than deuterium, based on his earlier paper. The Norront video clip claims: "Annihilation is the most efficient way of converting mass to energy." But in fact, prior to Holmlid - this was far from true - and it was extraordinarily inefficient. Annihilation required a beam-line with enormous acceleration gradient. Holmlid effectively discovered a low-tech method for pre-activation (densification) followed by photon irradiation, lowering the input energy by roughly a factor of a billion-to-one. It looks like a fabulous back-door method, but is it too good to be true? Can the deflated electron at some point "borrow" nuclear mass, to the extent that gluons cannot bind quarks effectively - thus the proton teeters on the edge of stability? Norront does not explain how and why annihilation becomes efficient with only a small laser, nor do they mention that gain happens at a lower rate with only semi-coherent photon input - IOW a laser is not required (plasmons are a substitute). If you look at the original theory of Mills, as evolved through the eyes of others, we imagine that the electron of the hydrogen atom is first giving up a cascade of UV energy via "shrinkage" or deflation - but then at very close proximity, suddenly there will be relativistic mass increase as the electron becomes relativistic. This mass-energy deficit at femtometer offset is met by coupling to the nucleus itself, which then becomes destabilized (i.e. the back door). Ultimately then, most of the excess energy seen will be derived from the nucleus, in addition to the ~500 keV shed from the deflated electron (so-called angular momentum). As nuclear mass is being extracted beyond a stability point - perhaps we have the key to Holmlid's result; where proton annihilation is indeed "the most efficient way of converting mass to energy." ------------------------------- This PR video was made for investors, and is impressive in its claims. https://www.youtube.com/watch?v=ZoWMJNT4J88 Of course, we are begging for more specific technical details about their progress. They claim to be converting charged particles from laser ablated dense hydrogen directly into electricity. That would be on a laboratory scale. Will it scale up? ....
