Hi,
here is a video of my new test cell with
graphite paper and alufoil generating up to
1.92 Volts.

It can drive drirectly a red LED.

Here is the first video of a few more I already made,
but must still edit.

Youtube is still working on the HD version to render and convert,
so come back later to see it in HD.

Regards, Stefan.

Stefan:

Nice video.  How long will this effect last do you think?

Nice work.

Bill

Hi Bill,
as long as the Alufoil will last.
You just need to change the Alufoil from time to time.
The graphite paper is not consumed.
If you build it this way, that the layers of alufoil and graphite paper are closer, it will also have more current and can be used to drive a Joule Thief.

This kind of reminds me of a regular 12 volt battery, except you are using caustic as the electrolyte.

This does give off hydrogen gas constantly though, and you won't be able to stop that until the aluminum is completely oxidized and consumed.

Hi Stefan.

have you tried using two different forms of carbon as a battery, 1. Graphite, 2. Charcoal, add an electrolyte and see if a Galvanic reaction takes place?

Hi ResinRat,
it seems to depend on how concentrated the NaOH is inside the water.
If you make it not too concentrated then the Alufoil will
not consume so fast.
I have to experiment more with the concentrations.
Also it seemed, when the NaOH concentration was too high,
the voltage dropped and Hydrogen gas bubbles formed on the alufoil.

Hi Jerry,
normally you need 2 dissimular metals to get a voltage
potential between the electrodes.

But charcoal is not a good conductor.
YOu will probably get about 01. to 0.2 Volts from
graphite versus charcoal, but the current output is very weak.

The current output in my cell could be boosted
via a Stainless steel mesh put inside the graphite-acrylic
mix.
This was also done in the Zinc Air battery and helped to get the
huge output. Then the inner resistance of the graphite electrode
will not be KiloOhms , but Ohms and then you will
get much higher currents.

This I will also try next.

Regards, Stefan.

I made today a few new electrodes with graphite powder, lampblack powder and
Pottassium Permanganat ( KMnO4) and the acrylic binder and put this onto
stainless steel mesh and onto another mesh, an Aluminium wire mesh.

It is still drying and tommorow I will do my first tests with it.

Stay tuned.

Regards, Stefan.

These are my new Metal mesh-graphite-KmnO4 test electrode materials.

See the attached pics.

Will do the experiment tommorow, when I have daylight.

Regards, Stefan.

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.
