KARPEN PILE

What's the status pomodoro?? So we have stablility for Pd/Cu,Pd/C,Pd/Ag correct??

Relax @sarkeizen it won't be long now.what you can do in the meantime is quickly build my other design  under the threadname 'perpetual batteries by vasilescu karpen' for a direct violation of the second law thermodynamics.

Cheers for link, I'll have  good read of it later on today.

The stage I'm at is testing  the pure Silver foil instead of the wire or plated copper.   


Need to make sure the system is steady for a few weeks before I make the permanent totally sealed in glass version.

Well things are not going too well. A nice polished and solven t washed silver cathode in 0.1m na carbonate does very well initially but after discharging for 2 hours recovers very slowly    and each time the voltage is always weaker. Silver is still nice and bright. Intake the electrode out for a second and when I put it back all is good again, for a while.  I'm starting to think that the cathodes that worked had slow to react oxides from the anodizing process which can power the device for a long period of time.

0.1m sodium carbonate is too weak.its pH is much weaker than the KOH so anode voltage dived and cathode voltage rose.you must use concentrated Na2CO3 if you do use it. Its possible that you did leave some oxides of silver in samples but its also possible that hydrogen buildup was too much in the layers that were too black and fine.you have to anodize your Ag briefly,cathodize it shitless for thin grey-black adherent layers that won't cause H2 buildup blockage.
