Mk1 interesting research regards. Today I made a small battery with copper wire around an aluminium in bleach and water gave about 0.3v and 5ma and a copper rod in an aluminium pipe that gave 0.6v at 2ma. Interesting when using copper wire gives more amperage.

@Mk1
Thanks a lot for your document  :o
That gives me a lot of useful data !

So adding a bit of NaOH with the salt is very useful for power output. That's good.

1- Did you add graphite powder to the pencils ? If yes, can you explain how ? What "glue" did you use ? 220mA at almost 2V is enormous compared to my 10mA at 0.6V without NaOH  ;D

2- Can you give a shortcut in quantity to prepare the electrolyte, like giving measure in spoon/liter instead of Moles please ?
Congratulations, and thanks for sharing, an essential document !

Replication of Pete's (PeteIdl4) aluminium - copper wire cell:

See Pete's tutorial videos (and my photos below):
Part 1 http://www.youtube.com/watch?v=B9YqFY-Z0dk (video by PeteIdl4)
Part 2 http://www.youtube.com/watch?v=ZeQof7ue9xA (video by PeteIdl4)

- Kitchen paper towel sheets were soaked in saturated salt water and then dried in the sun. They were a bit stiff after that but that helped when rapping the paper over the inner aluminium sheet and over the copper wire windings.

- When winding the wire over the (paper covered) inner aluminum sheet I took care that the windings did not touch.

- The outer aluminium sheet and the inner aluminium sheet are held together by a little screw which also holds the cable to the aluminum.

- Air can enter the cells from three sides.

- Four cells are connected in series to get about 2 Volt (without load)

- After the cells were finished they showed about 0.5 Volt, but almost no current. So I added a little water with a pipette. Just enough to make the paper damp. After that I am getting great results (almost for three hours till now):


0.5 Volt without load

0.4 Volt with 1 mA load

0.2 Volt with 4 mA load

short circuit current is about 6 mA



I will report in the coming days how the four cells are holding out. They are driving a Joule Thief which draws about 1 mA (while the four cells in series hold 1.6 Volt steady).


@ Mk1 - Thank you for the aluminum cell PDF-document!


Greetings, Conrad

Update on the replication of Pete's (PeteIdl4) aluminium - copper wire cell:

Four cells in series are driving a Joule Thief for the third day. With a load of about 1 mA the four cells in series are easily holding 1,6 Volt (0.4 Volt each cell).

With a 10 mA load the four cells are holding 0.6 Volt (0.15 Volt each).

I had to add water on the second day (with a pipette) and constructed a "press mechanism" to hold the aluminium sheets and the copper wire windings closer together (see attached photo). This increased the output (short circuit current now up to 18 mA).

An other cell based on Pete's (PeteIdl4) aluminium - copper wire cell:

Because I like the aluminium - salt water paper - copper cell (the materials are easy to obtain) I built another one.

This time I used a copper sheet (instead of the copper wire) and an aluminium sheet (instead of soft drink cans) to see if that works better. The paper was soaked in 10% salt water (10 grams salt in 90 grams tap water). The metal sheets are 60 x 90 mm (rather small).

It seems that a "press mechanism" provides higher amperage, therefore I built four cells which are tightly pressed together.

This design also allows rapid assembly and disassembly (in case one wants to change the paper or check corrosion on the metal sheets).

Results with four cells in series:

no load 2.6 Volt (4 x 0.65 Volt)

3 mA load 1.6 Volt (4 x 0.4 Volt)

7 mA load 1.2 Volt (4 x 0.3 Volt)

10 mA load 1.0 Volt (4 x 0.25 Volt)

short circuit current is up to 25 mA


7 to 10 mA (at 1 to 1.2 Volt) are enough to drive a Joule Thief with a few white LEDs. For instance one could build a flash light (for use at home) with such a "battery". It should take a very long time till the copper and aluminium are corroded (may be years). Water has to be added occasionally. And may be the paper has to be changed every few months because it might fall apart.

Of course, one could build much better batteries with other materials (graphite, zinc, magnesium and some acids), but the goal is to build a very simple battery with materials commonly available (or from materials which are often thrown away like soda cans and old cables or wire from torn down buildings).

My next attempt will be a steel - damp salt paper - copper cell.

Water/Air (water vapor) battery
« Reply #141 on: July 04, 2010, 08:16:00 PM »
Hello Everyone,

Vids have been uploaded regarding the 3 water battery experiments in case anyone is interested. The vids show a progression, ending at the third experiment with the tiny 1 inch by 1/8 inch units producing 3- 3.5 volts  each without any Joule thief or acid, just tap water and enough current to run super bright LEDS.

Blessings,

Littlechristgod

@ rock321

Could you tell us where the "vids about your water battery experiments" are to be found?

A link would be great.

Salt paper can absorb the ambient humidity, which could very likely shorten the battery's life.

@ rock321

Unfortunately you forgot to mention which metals you used for the cells presented in your videos?

The videos are therefore of no use, a waste of your own time and of the time of onlookers.

Either you disclose your cells completely or you keep them to yourself. Teasing people is bad form and not the purpose of this forum.

I bet it's silver wire and aluminium wire.
(Edit: May be silver soldering wire, or just silver coated copper wire )
But I might be wrong ...
Very good idea. Rock I am impressed by the power output !!! from such a tiny piece !!!

I am going to try the silver/alu
I just got aluminium wire roll, used for welding purpose, it's very cheap.
Silver wire is also relatively cheap, silver is at around 600 Euro per kilo.
Silver as a potential equal to carbon ( +0.8V ) and does not corrode in the process.
(Only graphite has higher positive potential at 2.2V, in the chart)

Edit: so much apparent power for such small pieces of wire, even using silver wire would be affordable, because 1 inch of silver wire would cost like 10 cents.

Graphite or carbon does not corrode either and is much cheaper to obtain.  Check the metals chart I posted a bit back.  The best bang for the buck is graphite/magnesium

I have never seen such small pieces of wire giving 3.5 V and lighting a white LED directly ?!
Of course he has 2 cells in series, but it's still like 1.75V per cell !!!
And he says it's running since 1.5 month !!
I think he brought some metal from the moon or mars, because we don't have such here :)
