I'm always careful to separate BrLP's experimental claims from Mills's theory. On the experimental side, I consider the matter far from settled, even with the purported replications. I followed up on one such replication that was advertised as having been connected to the Harvard Smithsonian Center for Astrophysics (CfA). It turned out to have been done on the CfA premises by an independent contractor with no clear connection to Harvard, and the purported confirmation lent itself, it seemed to me, to other interpretations. Despite this underwhelming experience, I am open to the possibility that BrLP have an experimental phenomenon.
Is there a necessary connection between anything that BrLP might be seeing in their lab and Mills's theory? And have there been replications that have supported elements of his theory? This part is even less clear to me. But judging from your confidence I gather that you have done the footwork on this and can fill in some of the details for us.
I now accept the reduced orbital behavior of the atom below base level as a characteristic of gainful (overunity) technologies, because Holmlid has deminstated it experimentally. Mills is wrong in his interpretation. These compounds and elements which show low electron orbits are described in high pressure physics as metalized hydrides. One of those hydrides is metalized water. Mills calls it HOH.
I am using Mark LeClair's name for the metalized water nanoparticle, the Water Crystal. Connecting this subject to LENR, Randall Mills has found that water crystals are the active agent in the SunCell. Mills describes this special form of water as having no covalent chemical bonds. This lack of chemical bonds is a result of charge separation between the positively charged "hole' core of the nanoparticle and the electron cloud that orbits on the surface of the core of the superconductive crystal.
In the 1960s, Joe Papp used this process to produce a patented water explosive that could shred 5/8 inch stainless steel pipe. People have been injection HHO into their engines for many years now.
I beleive Holmlid, high pressure physics, and LeClair about the details of fractional electron orbitals, and not Mills.
The primary difference between the two interpretations of factional electron orbits is the nuclear nature of the interaction between these collapsed elements and other matter.
