Szpak, et al took a video of hot spots on an electrode under the electrolyte, claiming they were ‘mini-nuclear explosions’. I added that they could as easily be chemical. Why do you think this is unprovable, and even, not already proven?
Hydrogen finds its way into the grain structure of the transition metal lattice where it accumulates in a defect in that lattice structure. The chemical bonds forming the lattice compresses the hydrogen as the amount of hydrogen atoms increase. Phonon vibrations also contributes to increasing pressure on the aggregation of hydrogen atoms confined within the lattice.
When the density of hydrogen atoms increases to a transformative level catalyzed by an increasing level of pressure, a change in state occurs in the cluster of hydrogen atoms where that cluster transforms from a gas into a metal. This solid hexagonal crystalline nanoparticle is then coated with Surface Plasmon Polaritons(SPP) which provides superconductivity together with the meissner effect. Such a transition has been experimentally observed by Miley, Holmlid and Hora.
After its formation, this hydrogen crystal erupts from the lattice and forms a crater most often marked by a melt of high temperature resistant metal lattice material mushrooming from a central exit cavity. The LENR reaction that produces this eruptive event results in a copious generation of alpha particles that are broadcast from the lattice in a spherical pattern whose density is governed by the inverse square law. The energy produced by the emergence of the hydrogen crystal from the lattice is captured and stored on the surface of the hydrogen metal particle and magnetically reinforces its structural integrity. The hydrogen crystal is now independent of the lattice and proceeds to catalyze more LENR reactions. Sourced by the metal lattice, the eruptive event most generally is surrounded by transmutation products derived from the lattice metal and other lattice surface material coverings that are then broadcast from the eruptive event.
