Hello Everyone,

By the Grace of God the Father and the gifts He's given through His Son Jesus Christ, I'd like to share some of the data from experiments done with versions of this type of battery.

I've had one of these type of batteries running a super bright LED of 28,500 mcd and 3.5-4.0 volts for 6 weeks continuous. The decay rate of the ribbon seems to be on the order of about 1000 hours. Then you can use the remains for hydrogen generation. Each one of these mini batteries that powered the LED produced from 3-3.5 volts. Run in series they produced about 5.5-6 volts.

I did not need a JT or any other type of electrolyte other than tap water. The higher voltage is acheived very simply and further experimentation should get 6-7 volts out of only one tiny unit (1 inch by 1/8 inch).

Hope this data is helpful. I'll be posting on Youtube probably (God Willing) tonight.

Blessings,

LittleChristgod

Hi everybody,
I just got back from 3 nights in the camper.  :D
the first thing I noticed was that the mag ribbon that I left in the salt water is broken into 2 pieces, and the same length of ribbon in the MgSO4 solution is fine.
There were few bubbles on either ribbon when I first touched them, but now after the 'agitation' is stopped, they are both producing many bubbles again.

-----
Just before I left, I bought a 3 foot piece of 1" copper pipe from the hardware store.
It was a bit longer than 3 ft and I ended up with 5, 7" long pieces and 1, 3" piece.
I made 2 batteries; one, with the 3" and one with the 7 inch long piece. (and 4 left unwrapped.)

I took a pic of all the ones I have so far with the 4 bare copper tubes of potential batteries.
The 3 inch battery is lighting the JTC with 2 leds in parallel on the secondary. It can light more in parallel, I just took this pic.

In the pic you can see the 3 inch one right in front of the very tall one from last week.
This I did because I have in mind to cut that very long one a little shorter to make 7 inches and a 3 inch piece for another short one.

---
While these lights are bright they are not bright enough to light up one of those globe lamps. (Like the tiny toroid world light.)
I want to make them as bright as that, because that is a long lasting useful lamp.

One more thing to mention is that in about 50% humidity, these are drying out in about 3 hours.
It will be very interesting to see if they outlast the ones covered with tape.
Oxidation vs being "on" for longer.

If the Air battery thing is really true (the korean sea water battery uses only mag and air in sea water)  then while the electrode ends seem off then energy is leaking out somewhere.)
The pic shows from L-R
The nearly useless carbon rod wound with Mg ribbon in the green glass. (I think this is the wrong kind of carbon rod, or something happened to break the magnesium ribbon apart under the tape.)
The 1/2" pipe which is wound with tape over the magnesium,
The really long one,
the 3 inch which is lighting the 2 leds,
Then the 7 inch and
4 more unfinished copper tubes.

I like the copper because it is about $4.40 for a foot long piece of 1" pipe, and the 7" length is $2.60. I think this is very affordable.
Now to make it a strong producer!  ;)

Here is the pic.
I think the most interesting thing today is that the mag ribbon in the table salt was broken after 3 days and in mag sulphate was fine.

I hope this is not too confusing!

Here is what I should really be showing you.
In the one I am showing the broken pieces of magnesium after 5 days in NaCl.
The copper wire in the same bath looks great.

The second pic is the mag wire after 5 days in the MgSO4 solution and its copper electrode also looking good. (and the others, the NaCl electrodes are in the background.)

Hi all

I just discovered this link about high voltage (electrostatic) air batteries made 100 years ago! 

 http://amasci.com/emotor/duluc.html

"Duluc/Zamboni Electrostatic Pile

The DuLuc Dry Pile
High-voltage source
©1996 William J. Beaty
The Duluc Dry-Pile (also called the Zamboni Pile) was an "electrostatic battery" permanent power supply used in the early 1800s and constructed from silver foil, zinc foil, and paper. Foil disks of 2cm dia. were stacked up several thousand thick and then either compressed in a glass tube with endcaps and a screw assembly, or stacked between three glass rods with wooden endplates. Of course this is simply a Voltaic Pile, a multi-cell electrochemical battery, albiet one with output potential in the range of kilovolts. Each cell used nearly-dry paper as electrolyte, with zinc foil for one electrode and silver foil as the other."

***************
This was used a source of power for "Perpetual Motion Machine" also described on above link.  Maybe modern materials can improve on this idea for low voltage applications?

Thanks jeanna, I am impressed to see how little the MgSO4 solution attacked the magnesium ribbon compared to the Salt solution !!
That's a very important point !!
What is your recipe to prepare the MgSO4 solution ? Where you bought it, what quantity in water ? ... Edit: Ok I found that MgSo4 is just Epson Salt  ;D

Even the copper seems not corroded at all !

I want to try to make graphite thin film ... powdering graphite then put that on glue tape, to save on the graphite volume used ...
I read somewhere that they use wax and/or clay mixed with the graphite to make the pencils. I'll try to see what results I can have to make a graphite thin film in my kitchen  :D

I'll try also copper as you suggested  ;)

@ Stefanafreter:

You can get cheap powdered graphite designed to be used as a lock dry lubricant.  It comes in a small toothpaste type tube and would be easy to use for your tape idea.
Any auto parts place should have some, along with some hardware stores, etc.

Hi guys impressive batteries. Anyone knows where to find magnesium from trash?
Cookware maybe?
Thanks

Yep, thanks Pirate, I found Graphite and Lithium grease for less than 10 USD a pot in the "Home Depot" ... going to try them as electrodes as soon as they are dried up a bit.
I also put some graphite grease on a piece of pvc pipe, and added some graphite powder to thicken and densify the layer (can buy from artist drawing shop, 10 USD for 150g pot).
I'll keep you informed asap.

Edit: Grease is a strong insulator, be sure to add a lot of graphite powder to the grease until it becomes electrically conductive !!
I put a layer of plastic net underneath that I fill with the mix, to get an even layer on all the surface.

I also got some candle wax to try to mix it warm with graphite powder, because when cooled it could form a stronger and thicker layer, and it could be molded in any form ...

I think magnesium powder is very hard to find, because it is highly reactive to air and water ... but it's used in fireworks, mixed with aluminum powder to.
I'll first use magnesium ribbon with a file to make small quantities of powder for testing.

@Stephenafreter
Be very careful with magnesium powder, it will ignite even with just a small spark. I've had it light on me a few times. Other than that sounds interesting, I'd like to know how it turns out. Keep us posted and keep up the good work.

@Jeanna,
Great job on your tests with the electrolytes. I was very surprised to see that the magnesium sulphate hardly damaged the ribbon compared to the salt. This is very interesting. Thank you for the good work, I think you may be on to something.

-Pete

Graphite electrode
« Reply #131 on: June 30, 2010, 05:18:03 PM »
Hi, I find that a graphite electrode is a very important advantage compared to others because according to the excellent potential chart linked by Pirate, http://www.thelenchannel.com/1galv.php, it has the highest positive potential AND it is not corroded during the reaction !!

It's even higher potential than gold or platinum  :o

The challenge it to make a hollow graphite electrode of large diameter (20-30 mm, 1") that is strong enough and can be re-used, by changing the external magnesium ribbon when it's exhausted.

I suppose that graphite pencil manufactures use pressure to put their graphite mix in form. I am looking for a way to do without the need of a press. Thanks if you can help to find the way.

Grease graphite electrode
« Reply #132 on: June 30, 2010, 06:04:15 PM »
Quick update, good voltage reading with the graphite grease electrode, but not enough power for the joule thief. So far I got much less power that around the 8mm diameter graphite pencil ...
Tomorrow should try with wax + graphite.

Edit: Measured resistance between 2 points of the graphite pencil is only around 20 Ohm, while on the graphite grease it's around 15k Ohm, that explains why there is not much power out ... the electric resistance is too high.
I'd better look for a conductive binder element, like a water gel ... any suggestion ?

The binder doesn't need to be conductive. You just have to add enough graphite.
You could use acrylic paint or epoxy. Just use as much graphite powder as possible and it should have a low resistance.

BTW. 10 USD for 150g of graphite powder seems a little high. I got 150g for 3 euro at my local hardware store.

Hi all

I just discovered this link about  (electrostatic) air batteries made 100 years ago! 

 http://amasci.com/emotor/duluc.html

Look at this
http://en.wikipedia.org/wiki/Oxford_Electric_Bell

The thing has been continuously working for 170 years now and it will probably keep going for few hundred years.
No one really knows what's inside but I guess it's probably zinc foil, paper and manganese dioxide. The paper might have been soaked in zinc sulfate solution and then dried.
