One interesting possibility arises from the experiment due to the factthat there is no fusion without a relatively strong magnetic field nor without very cold (but not liquid) deuterium gas in that strong field.
Both conditions are required. That intersection of two critical restrictions implies that a "temporary BEC" may exist under conditions where a full BEC is not seen. TheBEC assembles a dense target for muon interaction, on occasion. IOW there is recurrent boson condensation but on a transient basis. Only in the condensed state will fusion occur. And only a small population of deuterons is every in that transient BEC state. This was never considered, and no group pursued the finding further- probably because only a few muons from cosmic rays are available; and at the time there was no cheap and low energy way to produce muons. That may have changed --------------------------------------- The knock on cold fusion over the years has been lack of neutrons. Yet that "lack" is not accurate. As it turns out, 15 years ago Mizuno and others performed a defining experiment. Problem is... almost nobody quotes it today, or even knows about it. "Neutron emission from D2 gas in magnetic fields under low temperature" is the paper from 2004. Mizuno, Akimoto, Takahashi and Francesco Celanihttp://www.lenr-canr.org/acrobat/MizunoTneutronemi.pdf Summary "We observed neutron emissions from pure deuterium gas after it was cooled in liquid nitrogen and placed in a magnetic field. Neutron emissions were observed in ten out of ten test cases. Neutron burst ... were 1000 times higher than the background counts....We observed a clear neutron energy peak at 2.5MeV." (indicates d-d nuclear fusion) Comment: why is this study not given the credit it deserves? The authors are top notch. The results are astounding. The experiment was partially replicated by Ahern at MIT. The neutron bursts align with cosmic ray bursts (which create muons which then catalyze fusion). The solenoid magnetic field of .8 T is large, but could be obtained using permanent magnets. This experiment begs to be replicated today using permanent magnets and a tiny muon source using laser irradiation.
