Approximately 25cms apart. At 2A average current the density is pretty low.

Thanks- similiar in some ways. I think though we MIGHT be looking at light water hydrogen/alkali metal LENR.

How long have you been running the system for? Really glad you are having a go at this btw.

Well done. Keep it up a bit longer. The good (if a little crazy) ol' boys in the Texas wing of the CC research group have been doing a run - the second of two which have ended with containment failure. Not seen any data yet, but I am taking the liberty of reproducing an email reporting on the cell about 30 hours before containment failure.

"Micro bubbles less than 1mm, bubbles the size of BB's, are easy to comprehend with normal fluid physics, electrode reactions under polarizing voltage, and possibly entrapment of coalescing gas bubbles in the CC matrix. Neal is reporting something beyond this.
He keeps hear ing sharp crack (seems originating at cathode locale), this accompanied by very large bubbles. I may be foolish, but I think this is the telltale, or smoking gun, of initial bump boiling due to XSH. I feel that a nuclear active environment, will not be just one happy particle, but that a statistically significant ensemble builds or starts building the moment current is active through CC-LENR reactor cells.
One successful He formation, or other nuclear transmutation (likely, considering the absorption cross sections of cold neutrons with all nuclei), could release sufficient energy to either increase the NAE ensemble, or trigger a small chain nuclear reaction, thus releasing macroscopically detected events.Such an event could be a macro-bubble. This might be followed by cavitation, that sparks additional electron capture by protons, deuterons, and triton nuclei.
N*** hears the sound, I also have heard it, we have seen the bubble, and an transverse wave from cathode toward anode. Next we undertake to capture these events on film lighted, and unlit, to check for possible scintillating transients, or cavitation plasma emission of light. I cannot fathom why these would ignite the electrolysis gases, unless partial pressures are outside the explosion limits for hydrogen-oxygen. Odd indeed, but we will see what we see. We needradiation detectors in the worst way."

To a certain extent Eric. I don't have permission to tell you all the names - if you want to know more it would best be managed privately. Group leader in the US is Dr. Howard Phillips. There are six group members (plus Howard) in the US, mostly based in Texas/Oklahoma. Howard is the guy who discovered how to make Catalytic Carbon btw, he is one smart cookie. This is the CV of his company, also based in Oklahoma. As well as the US group, there are 4 of us in the EU, me and one other in the UK, and one each in Holland and Italy.

CC is definitely not just 'ordinary' activated carbon as used in filter systems etc. I suspect that it is the lead doping which turns the carbon grains into a quasi-polar oxide after the required perioud of exposure to current (12AH). This electrolysis needs to continue for a lot longer -maybe 100 hours - before anything unexpected happens. This is not in the public record, but I am told recently there has been a closely - but not exactly- related XSH event at a commercial company who were using a variation of this method to make hydrogen under pressure- in order to be able to fill cylinders directly. I suspect the variation is the problem, but right now can't disclose any more. Not my experiment.

This comment is from one of our research group on reading the paper you pointed out to me...some of it may be unclear - the referecnce to HDO for example, but you can see it got people thinking.

"A very interesting paper.

Pd is a whisker away from Pb and as such this may have a very direct interest in relation to CC-LENR.

If Pb doped Carbon becomes ultra-absorbent… there is just so much to think about here.

Refilling of tanks, the reduction of H2O and the possible concomitant concentration of HDO.

Why does heat seem to originate at the base of the Anodes… could this possibly be a point of major Pb doped Carbon absorption?

Is it simply Protium that is being absorbed?

Gosh… it touches on so many aspects of our thoughts and work."

Quote from can

Has electrolytic activation of the carbon grains already been attempted by placing them close to one of the electrodes instead of homogeneously arranged in the water tank?

Well, some grains are close, and some are far away, the tanks are looseley filled with carbon grains, there is little totally free space. This arrangement might in theory (some theories) change the grains individual environments a lot, but in practice there is a steady voltage gradient right down the tank. You can see this gradient effect in what fans call 'HHO' cells, where only the electrodes at each end of the stack are connected directly, and the others in between show a 'floating voltage'. It may be that those carbon grains nearer the electrodes would show more catalytic activity, but in practice we have never separated them.

It is confusing, and you are not the first victim. The CC is made using ordinary granulated carbon. It can be crushed coal, coconut shell carbon, crushed wood charcoal or carbon black powder derived from burning natural gas ( gas-black). All these items have been used. We 'activate' these materials - turn then into catalytic carbon - using the simple electrolytic process we have described elswhere and detailed in Howard Phillip's patents..

That's it.
