Galvanized Plate
Below is a test I did with Galvanized plate
For now here are the pics. I used what I had at the time to put together. 6-32 nylon screws give it the gapping. The heads are being used, until i can find the materials I need. 6-32 stainless screws for power connections. connections are "+ - + - + - " for a total of 6 plates. In well water the power across the plates at 9.5 volts around 3 amps. No specs on this one or output.
