alufoil cell
« on: April 06, 2005, 08:39:24 AM »
Hi All,
enclosed is a picture of the alufoilcell in a drinking glas.
There the inner walls are covered with alufoil, then comes the papertowel,
then the active charcoal powder and inside the active charcoal powder
is the stainless steel wool.
Over here on the pic you can see only the alufoil and the red-white papertowel.

The cell was connected to the 50 ohm load already now for 3 days and the voltage
is now down to 0.28 Volts.
If I am going to let it rest a few hours and add some fresh water, it will
again start at around 0.5 Volts with the 50 Ohm load.

Regards, Stefan.

hi stefan,
what is the reason that you have the stainless steel wool inside the charcoal? You would be better on to use only for contact a strip or thin rod of graphit, because you got aluminum foil as the negative and charcoal as the positiv if you put a second positiv with the SS wool inside the charcoal the output will be reduced.
SS wool and charcoal build a cell on its own and the next cell is SS wool and the aluminum foil, to check this just connect the meter leads on the aluminum foil and the charcoal and then on the ss wool and the charcoal.
the only what you need is a contact to the charcoal and there the best is a smal graphit plate strip or a thin graphite rod then you can let out the SS wool and will see more output.
greetings
walt

The steel wool is good....it has tremendous surface area vs. mass.  But I agree with Walt.   There are better materials.   If you can get them spun like wool...

I saw online an electrolysis setup excerpt (The book was $2000 that I didn't have) that involved the cathode and anode being extremely porous, allowing for a surface area that far surpassed anything solid, and it increased efficiency by many orders of magnitude.

Hi Walter,
you are absolutely right,
but I wanted to make a cell, that everybody can make from things
he can buy at the supermarket !
Where can you buy graphite these days ?
It is pretty hard to come by and has its prize...

So stainless-steel dish-cleaner is easy to get in every bigger supermarket.

Okay, if you will find the older Zinc-Carbon batteries still anywhere ( not over here
in Germany anymore in supermarkets) you could buy one of these batteries and
remove the graphite rod out of it and use this, but as I said, it is hard to get for
the average person, who does not like to order special expensive graphite plates
from a special graphite company...


Regards, Stefan.

hallo stefan,
the easyest and cheapest contact graphit are the pencil lead from a carpenterpencil or afrom one of this thick pensils.The SS in connection with graphit powder gives a loss of around 0.2 V.
Dont take the graphit rod out of a zinc carbon battery because they are formulated to work with acidic paste and they are  after my experience bad connector.

walt

Okay, good idea to use a pencil lead graphite. Did not think about that.
Will try it out and let you know.
Okay, this is a cheap sourc of graphite, I agree !

I tested to replace the stainless steel wool with a graphite lead pencil rod,
but it performed worse !
 ::)
It seems that the small graphite lead pencil rod has too low surface area, so
it can not collect all the electrons from the graphite powder.

When I replaced it, the voltage went down to 0.18 Volt in a few minutes at
the 50 ohm load, so that was not good.
With the stainless steel wool it stayed at least at around 0.3 Volt at least
after many hours of use.

Also with bigger graphite plates it was not very much more, so it seems
it really depends on the surface from graphite to the collector material
and as Stainless-Steel wool has lots of surface, it is better under load !

Also I saw, that the active charcoal powder also did "eat up" the
stainless steel wool a bit. I had some pieces of ss-wool broken apart
from the rest as it was the case of the itching away of the ss-contacts
at Walt?s batteries, when they were in contact with the graphite cylinders !

Also my ss-sink in the kitchen got itched up by the graphite powder !
So be careful when you handle graphite powder with stainless steel
and water, it seems the graphite oxidizes the stainless steel away in saltwater !

Regards, Stefan.

Stefan or Walt:

Does the Aluminum get eaten up as the battery is used?

Hi michael,
stefan can probably answer this from his present test but I stopt experiementing with alufoil because of the consumption of the alufoil. Stefan's intend here was to show how easely with simple and cheap off the shelf (or the kitchen) materials to build a emergency power source where you could have a little lighting. maybe someday we would be happy to have this possibility.
greeting
walt

Hi Michael, yes, the ALufoil is consumed, but only very slowly.
For better power output it is indeed better to also use the stainless steel wool
from a dish-cleaner. This seems to have more power, than the graphite plate for the contact
to the active charcoal ! With a graphite plate to the active charcoal powder, my cell is now down
to 0.1 Volts after another 8 hours run. I will now change this again and use again the
Stainless-stell wool. Also the stainless steel wool seems to be eaten up after a while
by the active charcoal. But as these things are not too expensive to get in every
supermarket, this is indeed a good emergency battery which you can use to light
up white LEDs. ( with 3 or more cells in series or with only one cell and an oscillator circuit)

Regards, Stefan.

I revived now the alufoil cell somehow.
I did not change yet the alufoil nor any other thing.
I had only putting some graphite powder and some
active charcoal powder and some polymergel I still had
into the bowl and also did put a graphite plate into the center
of all the graphite-charcoal.
Then I dripped a lot of water in there, so it was very moisty and
let this then dry out for several days without connection to anything.
Now as the towel tissue has dried and the charcoal was almost dry
the cell had an open circuit voltage of 1.15 Volts again !

Then I connected a 100 Ohm load resistor and the voltage went down first to
0.55 Volt and then to 0.42 Volt where it stayed the whole night for 10 hours.
Now today the voltage is already since a few hours up to 0.45 Volt at the 100 Ohm
load.
So it seems also with the towel tissue alufoil-carbon graphite double layer
this cell can generate a good amout of electricity this way.
It really depends on the setup of these double layers and the
right "wetness".

Regards, Stefan.

Is this reactive to the sun in the same way as the AG cell?  You also mentioned that there was a voltage increase in the morning.  Is there any way you can correlate that to your local sun-rise?  Also, can you monitor at sunset a decrease in the voltage?  If so then there is some influence of the sun that the earth is shielding(at least partially).  Mention this in the AG post if it proves significant.

Hmm, this evening-night ( without the sun)
the voltage is up to 0.46 Volts on the 100 Ohm load resistor!

Could this sunrise aspect be associated with the ionic charge in the atmosphere, like the Northern Lights?

Hi
this could be, I just dont know how could a test be set up to proof or dis-proof this theorie, what whould be a material to shield the cell in order to block any ionic influence. any sugestions?
the increase is independend from sunrise or sunset, in my case and many others it changes also over night.
