[NewCandle] Getting started with aluminum foil

A couple other stray observations. Last year I did a pair of runs using a standard salt I believe (NaCl or KCl) and I intentionally shifted the pH a few points either way - adding either HCl or NaOH (or KOH) Tried to take the pH to either ~4 or ~10 respectively. Oddly, what I found was that in both cases, the gas evolution volume and degree of reaction (qualitatively)was reduced. For optimum results, the system appears to *like* neutral.
Now as for the H2O2 - honestly, it was just a shamanic selection. Lets see what happens, and see if whatever does happen gives us a clue to the overall system parameter set.
A good portion of the first three quarters of last year was given over to trying exotic salts - for the purpose of looking for elemental transmutation evidence (you DO recall that this whole adventure started out in the land of the LENR weird, don't you;) While Sam Faile always enjoyed focusing on those speculations, I tried to grok the experimental results for evidence of Casimir cavity influence of the essential reaction rate, energy, and direction. That was always my primary interest - does the tight annular roll and cavity geometry produce an interesting effect or result that could be validated. Otherwise, if my objective was to produce H2 fuel gas by hydrolysis, I would simply mix up a steamin' wicked bucket of lye and toss scrap aluminum in all day long! (Now don't misunderstand - I think a lye-water scrap aluminum H2 generator SHOULD be an essential part of every post-apocalypse wasteland community!)

****Thats interesting. I think there are different reaction rate limit parameters, one of the most sigificant is whatever inhibits the reaction from just starting right away, as soon as the water wicks into the roll. Even with salt water, we repeatedly would see a sequence... about a day of quiescence, then the "oil slick" when presumably machine oils are being carried away from the surfaces, a swelling of the rolls, then the onset of fine bubbles, then faster and larger bubbles, then violent boiling. But there was always a delay in the process - though with peroxide this delay was shortened drastically.

*****That could be very significant, and tell us a volume. I tried to take potentials and measure currents using DVMs, but was more or less unsuccessful. I was even seeing potential differences between roll inner and outer turns.
