In this case, it may be money talking. They had some serious investors lined up a few months ago, and this may be an indication they made a deal with one. No secrecy = no IP protection = no money. That is just the way it is.
Indeed. I was lucky enough to watch the video in question before it was taken down and bearing in mind Monty showed a heap of the inner workings and mechanics of the SAFIRE project, and the fact that most of their patents are to do with mechanical aspects of the project, rather than the production of energy or transmutation, it is not really surprising to me that it disappeared once they started talking about commercialisation.
Monty discussed in some detail the gasses used and showed the control panels in detail and described quite a bit about what was what. They had tanks of liquid Nitrogen, air, Helium, a tank he originally said was Argon but then said was air (unsure if this was meant to be a secret, as Argon is clearly shown in several places later on), Deuterium, high pressure Hydrogen, low pressure Hydrogen, and "more Hydrogen". Monty only discussed Helium being used in cryogenic pumps and also for leak detection (but see below). They de-ionise water and use for heat exchange and as "an electrical insulator". Nitrogen is apparently introduced to diffuse the hydrogen gas below explosive levels (and in the event of something going wrong will flood into the chamber to dampen reactions).
Here's where it gets interesting - the gas and vacuum control centre panel in 'SAFCON' had 3 main sections to do with the gasses;
1) Left - for gimbals and the antechamber, labels and switches for Air, N, He, H2, Ar
2) Centre - for anode, labels and switches just for H2, D
3) Right - for the chamber itself, labels and switches for Ar, H2, He, N, Air, O2
Other interesting things mentioned - LOTS of UV light is produced. A mass flow controller is discussed - it can apparently be used to allow very specific combinations of gasses to be used. The computer screen had (digital) labels for Argon, Hydrogen, Helium, Nitrogen, Air, Oxygen and various mixtures thereof. At the end the list of things the lab is capable of included *gravity shielding* of matter within double layers, *chemistry as a catalyst* to double layer formation, and sequestering of heavy elements to the core.
And perhaps the most interesting - when talking about the panel in SAFCON, Monty mentioned that hydrogen and/or deuterium is apparently introduced into the CORE of the anode, where it can diffuse and do funky stuff.
So perhaps there are two sites for transmutation; in the atmospheric Hydrogen/Helium/Nitrogen/Oxygen/Argon in the double-layers is forming the Lithium/Carbon/Sodium/Magnesium/Aluminium/Silicon/Phosphorus/Sulphur/Chlorine/Potassium/Calcium/Titanium/Manganese/Zinc, and then the heavy Tin/Barium/Lanthanum/Cerium and 4+ unnamed (presumably very valuable/toxic/radioactive) elements are forming at the surface of the porous metallic anode.
