I came up with an idea for a dry cell that I haven't seen anyone try yet. How about taking a piece of PVC pipe like 6" diameter,put threaded end caps on it with a hose connector on each end. Now on the side of the pipe take a saw and cut slits in it to slide the plates into then run high temp epoxy/sealant around the edges to keep the electrolyte inside.I made a very crude illustration on my computer.Sorry I am not an artist!
Also has anyone thought of using printed circuit boards to connect the plates and use jumper switches to connect either + or - or N to the plates instead of switching wires and soldering and all that for experimenting?
