Uh, dumb question, how is 1.7 volts "ultra high potential" ? Is that even enough to do electrolysis like they're talking about?
- ajb 5mo agoI think that may not be the potential used for electrolysis, but the chemical potential of the saltwater-metal boundary. But hopefully someone more knowledgeable will comment.
- manarth 5mo agoGalvanic corrosion typically happens at 0.5V (and as low as 0.15V in salt-water); 1.7V is "ultra high potential" in comparison with normal corrosion thresholds.

- Tuna-Fish 5mo agoThe potential needed for electrolysis of water is 1.23V in theory, in practice a bit more to overcome inefficiencies. 1.7V is enough.
