i am seeing a few diffrent designs that dont require any type of additive(lye, baking soda, ect.) What do you think these other designs are doing?

is it a closer plate design? special plate material?

I was thinking if i could pull off the plate design that is really close i won't need the any additive to allow the water to conduct electricity, as well i think that it will be more efficent because there are no additives.

I understand the bubbles will want to stick to both plates but i believe if i use a type of water circulation where i can push the water between teh plates physically push the bubbles out of the plates.

anyone have any sugestions or recomendations?
