axil : Rossi made his claims a few days after R.Mills made public his SUN-CELL direct current conversion of XUV radiation (which needs much more technical knowledge than Mills thought/had at that time ...).
Recently also Trump has confirmed, that he had no contact to Russia... If you like, you can believe anything!
The universe is charge neutral. Thus what about the counterpart of the electrons?? Who/what produces them???
If you have a nuclear process with about 1MeV excess energy that is available as a photon, then in the right environment a pair of electron/positron can be produced. If this happens inside a nucleus, then potentially a neutron will be converted into a proton and you get your excess electron. But so far no unusual (High energetic) beta-decays have been reported in LENR experiments.
Axil: It is time that you show us a concrete LENR reaction that produces muons. Holmlid is high energy physics! on a small space.
Unusual (High energetic) beta-decay is not my conjecture. My conjecture was direct conversion of energy to mesons through hadronization.
Search the posts on this site for posts by me using the keyword hadronization for an extensive overview of that process.
