I'm betting that the low voltage electrolysis resonance that Bob discovered is the same effect that Meyer *thought* required high voltage. That's strictly a guess from my own intuition, but I look forward to participating in this group and to our successfully demonstrating and understanding both effects and finding out their similarities and differences.
Thanks for mentioning some of the possible variables involved, and the bubbles occuring away from plates. I'm interested to know what the resonance experimenters here *think* is going on in the results they have had, -- electrical L C resonance? physical tuned cavity resonance? molecular resonance induced by -far-away- sub-harmonics? some special property of water that is not at all understood in mainstream science i.e. Keely frequency? Or perhaps the present resonance experimenters here really aren't that interested in a documented explanation of why it happens... (or in responding too quickly to unproven newbies who haven't shown any experimental results and don't yet have the standing to be asking such questions

Glenn, your point about edge leakage current is well taken. Below is a sketch of how each of my plate assemblies is made. The two pieces of 1/16" thick polycarbonate have the same outer overall area 'footprint' dimensions, but one is a U shape, and the other has a 5-3/4" x 5-3/4" window. The two are glued together, 'sandwiching' the SS plate. No SS edges should be exposed to any electrolyte. The (+) and (-) end plates will be different from the others, having only one side of the SS exposed, and the wires feeding them will be insulated from electrolyte.

This overflow arrangement is intended to allow a flowing electrolyte to fill all cells continuously from a common integrated reservoir with a small pump. If I am mistaken about this not causing a current leakage during filling, then I could undercut each overflow channel so electrolyte is forced to fall through air which should break up the flow and prevent current leakage. Cells could, of course, be filled on demand with high and low switch contacts as others have described here recently.
This whole 'sandwich' approach was intended to allow precise spacing while overcoming my present inablility to cut precisely spaced grooves in spacer plates, and to allow me to use thin, cheap shim stock. It should work ok for my first series plate electrolyzer, but for my next one, it may be worth paying a machine shop to cut grooves for me, and for resonance experiments, I'll likely use more rigid plate material to assure strict spacing consistency.
I think the W.A.Rhodes/Bob Boyce/Chris Moore grooved-spacer-plates approach has 'least common denominator' type **elegant simplicity!!!**.
