No one on this thread has answered why they won’t allow radiation detectors, because there isn’t any.
Might as well be from a science fiction novel.
One of the predictions of the Widom-Larsen theory of LENR is the lack of neutron flux and hard radiation. It also predicts random bursts of soft x-rays, and neutron bursts from reaction sites that have shut down. If I was Rossi, I wouldn’t want my competition insight of what is happening in my reaction vessel.
Any sufficiently advanced technology is indistinguishable from magic.
Arthur C. Clarke, “Profiles of The Future”, 1961 (Clarke’s third law)
That’s where we are right now with Low Energy Nuclear Reactions (LENR).
Take some time to read the presentations, you might learn something.
The US Patent office thinks they know something. See patent #7893414 “Apparatus and Method for Absorption of Incident Gamma Radiation and its Conversion to Outgoing Radiation at Less Penetrating, Lower Energies and Frequencies”
If I was a scientist/engineer who figured out a process to reliably create a usable LENR device, and I knew it was unlikely some one could reverse engineer it, I would keep my mouth shut and go into production.
Just like Andrea Rossi. Just start building them, and eventually retire filthy rich.
