Hi Stefan,

Mmmmmmmm... Looks yummy!!

Thanks for posting the pics.

Well,
I did the experiments today, but to put the KMnO4 into the graphite-binder mix
was not a good idea.
The voltage was lower.

The best setup was still again with the KMnO4 inside the NaOH-water solution.
The current with the graphite-mix on the
Stainless steel was in shortcircuit mode over 100 milliAmps,
so the Stainless steel mesh carrier really brings much more current.

But it also works alone just with a Stainless steel mesh, but then the current
is only about half, as if you still put conductive graphite on there.

Also copper as as the second electrode (instead of the ss-mesh-graphite) works also pretty good
and generates a lot of current.
I will post all of my about 10 videos I made today during the next few days, when
I have edited them.
I also want to try a few other experiments with it.

Regards, Stefan.

Can we put two of those cells in paralel and double the amps? Can we put two of those cells in series and double the voltage?

Only the aluminium foil is consumed? How long the aluminium foil can last before we need to replace it? How much costs a aluminium foil?

Stefan, how much current did you get with the copper? I was getting 1 amp+ using bleach electrolyte. You can use those batteries along with some homemade double layer capacitors i've been working on.

Sorry, been working on a few more websites  and did not yet have time
to encode and upload the videos.

Will hopefully still do this this night, at least a few.

Yes, only the alu foil is consumed, if you do it right
with the right electrolyte mix, so as Alufoil is cheap
and available in every supermarket you can get build yourself great
batteries for emergencies to power a few LED in series.

I would go with putting all the cells in series to get higher voltage
and also put all LEDs in series, so you only consume low milliamps.
This way, batteries last longer, if you only draw low milliamps
currents and not amps !

Bleach batteries are also great for higher amps, but the bleach stinks
a lot and is dangerous to your health and the alufoil is probably used up
much faster...

Regards, Stefan.
