I wish this picture was more clear and in focus, but here you can see the vinyl spacers between the plate edges keeping the spacing more uniform. The hole in the center will be for 4 (four) ceramic magnets I will install just to see if they affect output of gas. I plan to seal the magnets water tight and configure them with the positive poles held together in the middle and the negative magnetic poles to the outside in this configuration: (+- +- -+ -+). Each +- or -+ represents one magnet with a + (positive) pole and a - (negative) pole. This way the opposing poles line up directly in the negative plate area of the electrodes. They will resist going together as like poles on a magnet oppose or push away from each other so you may have to tape or bolt them together. I used short nylon bolts to hold the magnets together then used vinyl electrical tape over that. I then sealed everything in plastic Saran wrap then taped it all up with electrical vinyl tape to make it all water tight. Even if this doesn't produce a desirable effect on gas output at least the magnets will help draw heat out of the plates. I bought the circular ceramic magnets at Hobby Lobby and they fit perfectly inside the hole already in the plates.
