Perpetual batteries from Vasilescu-Karpen

Reactions for the cell in NaOH electrolyte: anode(nickel,totaly inert) 2OH-> O + H2O + 2e- and at the MnO2catalyst cathode: O + H2O + 2e- > 2OH-

[profitis]

Voltage for this cell calculated same as for karpens original: E= RT/nF ln kb1/kf1 - RT/nF ln kb2/kf2. K is rate constant of forward/backward reactions for O + H2O + 2e- >< 2OH-

I like the idea; it has been a long time since chemistry, but I remember liking it for it's algebraic simplicity


Nickel... "nickel catalyst hydrogenation"  started as 'nickel catalysis of hydroxide' but turned out 'nickel-hydroxide' is used as a catalyst.

Still need to do more digging

Your getting closer d3xor.did you know that nickel is so inert in alkali solution that its sometimes used as an oxygen catalyst in fuel cells? It coats with impenetrable Ni(OH)2 layer. You must dip your pyrolusite in HCl and warm for a few minutes to pit it with massive surface area.you must electroplate your nickel with nickel-black for area there.I get roughly 50-100micro-amp per mm2 pyrolusite!!! What's a square cm going to do..I can only get hold of tiny samples here.if you can get hold of large tantalum capacitors you can crack the shell off and get a nice size block of solid pyrolusite.

Large tantalum caps are used in the power circuit for computer hard-drives.usually yellow blocks stuck on circuit board in groups,each one about the size of half a pinkie-nail
