We need a much higher dielectric constant to get as much charge as possible on widely separate electrodes. That 2.1 figure won't do much. The reason for suggesting electrolyte is that a chemical change can release much more charge than you would get from a normal capacitor plate and at much lower voltage. AFAIK little attention has been paid to half cells (a single electrode in an electrolyte) that are given a high voltage pulse where the possibility exists for an enormous quantity of charge to be temporarily released into the electrolyte in the form of positive ions. To give an example, if we had an electrostatic motor of the Franklin type using 4 inch dia spheres charged to 100KV, each sphere carries about 0.6 microCoulombs. That same quantity of charge could occur in a half cell pumped with 1 amp for 0.6 microseconds. Pump it for 0.6 milliseconds and you get 1000 times more charge. Imagine Grum's Franklin motor having 1000 times more charge on his spheres!

OK So your electrolyte is your charge carrier as opposed to the electrode! just trying to get my aging head around this, I'm so used to electrode chemical change to carry the charge and the electrolyte to move the ions, it only has to be one as I use in my system, but there I use up over time the other collector/electrode, and only charge the one (with oxygen). So you are sugesting the brass dome is just the collector to put positive charge into the electrolyte, then when it moves to another contact point of negative potencial, it discharges, but the collector in the electrolyte is now, possibly the coil, and not the brass dome (just looking at your earlier diagram with the coil). Does the electrolyte have to chemicaly change, or does it just have suspended charged particles? All fascinating stuff which needs to be experimented with. Regards Mike The fast pulse, high voltage charge works well at controling the current
