In reply to Nigel Dyer's message of Fri, 22 Sep 2017 19:07:58 +0100: Hi, There is a much simpler explanation. The collapsing bubbles *contain* a mixture of broken water molecule pieces. Among those pieces there will be both Hydrogen atoms and individual water molecules. The latter act as a catalyst the shrink the Hydrogen, as do other Hydrogen atoms and O++ ions. The reaction is essentially chemical, but of a higher order (energy wise) than other chemical reactions. The COP is about the right order of magnitude, as is are the initial conditions required to initiate the process. They are creating Hydrinos, they just don't know it.
