I have measured the voltage drop at the green diode by using an oscilloscope. Till one week it shows continuously 1 V DC. I have placed two zinc plates in parallel and one carbon plate between them. The diode operates just above its saturation voltage. Thus a small current is allowed to flow. I use black Hawaiian salt in distilled water which was harvested on the island Molokai. One weight % of the salt consists out of activated vulcanic carbon. What are your experiences regarding the voltage at the diode?
