I use a current controlled CS generator, by increasing the 'distance' between the electrodes by means of a maze type container would THEORETICALLY help me by increasing the resistance of the DW so that i can keep the voltages higher where it tends to brew more efficiently, without reaching a low voltage so soon and limiting the process.
for example in my setup when i reach below 6v it seems reluctant to brew any more. and that's with a setup where I can increase the distance between the electrodes, when I reach a limit, I increase the distance between the electrodes so that I can brew again by increasing the voltages. I can get 38us roughly using this method, although I am an advocate of very low current brewing (0.1/0.2ma per SQ inch) and my setup is geared for this in mind, so my current controlled setup will go low voltage quicker than most to maintain the low currents I am looking for my brew. the reason I mention this is that I understand the wisdom behind the question and agree with this line of reasoning based on my experiences .

Then you punched a small hole in the material. Current could pass through that hole. If that hole could be moved around in the plane of that sheet of material, it could confound the silver ions trying to migrate towards that hole, as they rarely succeed in passing through it before it has moved to somewhere else. Could this allow an indefinite amount of silver ions to get into solution? I guess it is like creating an artificial sense of "infinite distance" between electrodes without there ever being such a thing. Another concept is to literally create a large distance between electrodes. Could this not also be helpful in reaching higher concentrations of silver ions? A way to do this is to create some kind of a maze for the ion to have to travel through. The problem is that the ions will over a short time diffuse so that they are even throughout the solution due to diffusion. This this would accomplish nothing. However I have heard of people socking the electrode, apparently the ions can have a hard time getting through the cloth to the other electrode. If you put a osmosis barrier in there, that just might do what you are wanting.
