The Alan/Russ experiment has been conducted by young plasma students for over a 100 years. This goes to show that there is not much new under the Sun. The glow tube experiment is a demonstration of the Goldstein–Wehner law.

The Double layers are produced in the plasma tube as well as in the spherical SAFIRE mode. What Alan did with the metal foil is identical to what SAFIRE did by inserting the Langmuir Probe into the double layer. The two experiments produced the same LENR effect when the metal was inserted into the double layer. In both these systems, the interaction between the metal and the double layer is to produce a population of surface plasmon polaritons that merge to generate a polariton BEC. In this plasmoid generation mode of the LENR reaction where the petal Condensate intercepts the energy output that the double layer reaction produces, that energy is reformatted in the singular way that the petal condensate is constrained to produce as a analog black hole. That reformatting process includes a very wasteful segment of the total output. The condensate produces muons (aka Meshuganon) with that fraction of total output energy that is essentially lost to the far field. Muons has a long delay time and they travel a long way from the place in which they were created. As Alan has observed, the generation of gamma radiation when the tube is heavily shielded is a sure sign that muons are being produced by the inserted metal surface. In the SAFIRE reaction, no condensate is formed and therefor all the energy that the LENR reaction produces in the formation of helium is retained as heat output. I predict that Helium 3 will be detected in a spectrogram of the gases in the glow tube over some extended period of its operation. Excess heat will also be produced by the glow tube in the same why that SAFIRE produces excess heat. Alan/Russ should take the glow tube experiment to ICCF-21. The SAFIRE people will greatly profit from the Muon demo.
