Perpetual batteries from Vasilescu-Karpen

Well, the idea of yours was a good one, and you did well with the limited equipment.  The MnO2 electrode seems to be used in Oxygen Reduction Reaction s(ORR)ystems. Havent had time to read into it as yet, but there is plenty of info and it looks promising for the cathode.
A week of data on the karpen cell I have here was wasted as I noticed that the discharge intensity magically dropped when I disconnected it from the $5k data logger.  Somehow the instrument was helping the shiny electrode along.  Now the 2sqcm karpen still works but the recharge time is huge and the intensity miniscule.  What I need is something like nickel but that does not dissolve or form oxides and has a low potential in oxygenated water..

Do you have any fto on glass lying around?

I don't personally. Have you tested the potential of such an electrode?

Haven't cheked it out but should resist oxidation,might make a good cathode instead of anode.try gold foil vs mno2 in alkali.I have tested Au/Mno2 but not for long time enough to determine if its constant

This is entirely offtopic; and hopefully people are still getting notices here But


So there was this youtube guy

which one of the videos he claims that isn't listed anymore
that it's just a carbon-steel spring deposited with tungsten or (I forget the other one)


Tunsten is often alloyed but rarely deposited
certain tunsten (TuS) tunsten sulfate is actually fairly magnetic

but the odd thing, is it's really a closed circuit; so it it somehow trapping magnetic flux and turning it into electron potential?
