Considering Alumiweld has a low melting point that can be melted with a propane torch. I wonder if adding magnesium filings to the melted Alumiweld might increase its output!
May be worth experimenting with different mixes like 50/50 or 60/40 and so on.

Got it !! ---- Eight sticks of Alumiweld
@All
I found the Alumiweld at Harbor Freight today. I only had a little time to test it when I got home but it looks good.
@Slider and Nick
That Bugs Bunny thing got me wondering about using this welding rod stuck in the ground next to a copper or graphite rod as an earth battery. That would be really cool if we could finally make a true "Bedini Earth Light". That was the original intent when this thread started long ago.
@Brad and Sawt2
I will try to get a cell going as soon as I can and report back. I'll use the saline electrolye with ammonia or vinegar to bump up the amps. The activated charcoal with a copper electrode will be the cathode. I have some solid graphite rods that I might try also.

Aluminum can create a layer of clear almost invisible oxides in a matter of minutes, sometimes, and needs to be scrapped off for it to really conduct well. The Al tubes I use have a layer of clear type of galvanizing, or something similar, and don't oxidize on that surface unless I sand it off. My cells are still outputting up to 75 mAs, months later...
Bugs Bunny: Actually there were no oscillators connected or needed, on the copper pipe mentioned. And no one said "What's up Doc"? either.Last edited by NickZ; 06-11-2012, 11:13 PM.

@Lidmotor - just to verify, did your cell get eaten up through the use of vinegar ?
It seems a very rapid process that you described. Certainly, the speed of ZA oxidation also caught me by surprise in your report.
For my little tests in tap water of the last few days -
The aluminium cells have both stopped running completely, which is very interesting. Did the simple act of cutting them from the heatsink pieces result in re-oxidation over the couple of days ?
Testing both cells with the DVM and oscillator loads connected, sees 0.442 on the burnt copper one and 0.446 on the unburnt copper one - which I expect to be 1mV less than the switch on point of the oscillators. Disconnect the loads and they climb up past 0.5V, toward 0.6V, but then drop immediately again on load connection.
The situation has occurred before, in outside yard tests with various metals. With no load there can be as much as say 0.780V or something, with copper and steel pieces in the ground, but connect a load and the dip is to 1mV less than the exact switch on voltage of the transistor. A puzzling situation, but common in such experiments.
The fence wire cell remains exactly the same
The voltage output beats galvanized steel and the amperage is not fading at all 
Looks good for long term and it's no way a rare material.
Had a comical thought about that and relates to Nick's observation build of multi-oscillators using the same copper piece -
Drive up to the Energizer battery offices at night after a heavy storm. Find one of their copper water pipes outside and connect a bunch of LED oscillators low down between the pipe and the fencing around their property.
Place a sign on the ground that says "Bugs Bunny woz 'ere"

Alumiweld?
Thank You very much. I checked the Alumiweld web site and they say this is a zinc alloy. There is a Harbor Freight Store that I pass on my way home. I am stopping by there today and will pick some up. I do plan to parallel this test with the 97% zinc rods that I have to see if there is any magic in this alloy. I hope to get the positive long term results you have reported. Can you post a picture of your cells, or report the size and how they are built? Again, thanks.Originally posted by Sawt2 View PostBrad
I believe the rods at Harbor Freight may be Alumiweld, you might check their website for composition.

BradOriginally posted by b_rads View PostGreat job on the research! Mine are still holding together and I have not taken any apart to check, I am certain I will come to the same conclusion as yours. Hard to see anything in the alloy mix you show that would create any magic. I have some 97% zinc rods that I would like to parallel with your test of the Harbor Freight Rods. If you can share the build and electrolyte mix, I will try to mirror your build for comparison. Even if this turns out as purely galvinic (which looks like it should) a long running cell with useable current is fine with me. I could not find anything on the Harbor Freight site that indicated what their rods were made of. Good investigative work

I found that Lincoln Electric 4043 Aluminum MIG wire at Lowes yesterday and bought some ($13 for 1lb. roll). I did some testing and it didn't work out that well so I looked into what it is made of. It is basically all Aluminum with trace amounts of other things. Chemalloy according to the patent looks like this for a 100 lb batch:
Zinc --82 lbs.
Aluminum --8 lbs.
Yellow brass --8 lbs.
Solder (tin/lead) --1.5 lbs.
Silver or Nickle --.1 lbs.
My test cell worked but the wire was quickly eaten up and broke up just like a regular Aluminum wire cell would. It isn't the Chemalloy aluminum welding rod that we are looking for. I will try to get down to Harbor Freight today and get some of their "AlumiWeld" rods which are the zinc based stuff.
My other cell using the ZA metal that I got on Ebay did work quite well but dropped off in power. I took it apart this morning and there was a black oxide forming on the surface of the ZA anode. The good news is that there was little or no pitting.
----And the quest goes on.

Aluminum MIG wire
Brad---Originally posted by b_rads View PostAfter a full 36 hours, the 6" cell is sitting on 70mA. This seems to confirm what I have read about this cell. Let's see if it will hold there or continue to drop. It has been under load the entire time with LaserSaber's Mini Joule Ringer circuit.
Could not resist the 6-pack, lol, so here you go. These cell are 3" and 6 in series gives 3.8Volts and 150mA. This is 7 10mm LEDS without any circuit.

@IB - Shut it down for the night. I will be happy to start that test tomorrow.

plengo,Originally posted by plengo View PostI noticed something on my cells. I have been testing the same formula (Mg, sand, carbon, alum) with different quantities of alum. More alum in seems better. Now, i also have been adding water with and without almun.
What is very interesting is that the cells that i add more water with alum, after the cell diminish substantially its output power, is that alum will block all the inner micro-tubes formed that conducts the water and crystilize from within and break the cell and destroy it.
The cell even grows in size to the point of cracking the surrouding shell.
The cell when first made goes through a formation of its internal water conducts that allows the water to be decomposed in its parts while generating energy. It is necessary to let the cell to dry in its first months while running a load. After that first dry you can only add clean water, otherwise the cell will die.
The cells with iron pyrite performs better too. Corrosion is there but it does not corrode all. It gets to a balance point where the Mg is gray (MgOx x = 2, 3 or more) and Mg.
Fausto.
When the cell is going bad, do the volts go down first, and the amps stay up?

Looking good Brad, let us know how the cells hold out.
Slider, funny you should ask, about back yard non rusting materials to use on the cells.
I had some of the power line wire that the electric power company uses here for their street lines. I had some of that's laying on the ground going from my house to my water well, for the last 15 years or so. It's aluminum alloy, with a center steel line, and none of which had rusted, laying there for years.
So, I took some yards of the aluminum wire and made several cells with it. Using a 1/2" copper pipe cut about 8 in long, and the Al wire wrapped around it with a paper separator between, Lasersaber style.
It worked good, but as more salt was added to the paper electrolyte separator, it did start to eat the aluminum wire as well as the copper tube, in time. If you let it dry out, the voltage and current dropped. If you wet it again, it came to life again, as is normal for the Lasersaber type cell. But, it was just using some back yard scrap aluminum wire and copper pipe, ocean water, or table salt. This was made almost two years ago, or so.
So, I wound the same type of wire around my 6 foot copper framed pyramid, using a cloth separator in between. But, it had no conduction dry, nada, zip, zilch, zero. Oh, I think I may have gotten a 1/4 volt maybe, or less. So, I wet the cotton cloth separator, and of course it started to work. The more separate coil winds I placed on the same copper tube pyramid frame, the higher was the output. All the separate coil winds were separate cells, but mounted on the same copper pipe as their positive rail. And that is what happened with that. So, long as you wet the paper or cloth separator, it gave several volts, and a some mAs, which would brightly light some leds. I just don't remember the exact readings now.
The main thing that I learned from doing that was that the more separate but series connected winds of the aluminum wire or coils that are placed on the same copper pipe, the higher was the output.

just a little info that might be worth exploring ( mentioned it to slider ) with your battery mix as most of us has a fridge
How to Revive a Dead Laptop Battery with Step-by-Step Pictures
The same freezer that holds your frozen pizzas and TV dinners can often bring seemingly-dead laptop batteries back to usable (though not quite like-new) condition.
just thought you might like to know thissome info : besides water expanding on freezing
Other substances that expand on freezing are silicon, gallium, germanium, antimony, bismuth, plutonium and other compounds that form spacious crystal lattices with tetrahedral coordination.
ps: magnetite is also tetrahedral structureLast edited by MonsieurM; 06-11-2012, 01:21 AM.

@Nick - after reading your post I started wondering about the fencing in the backyard. It's been there for many years, no rust, the common interwoven steel looking stuff of about equiv 10 gauge copper.
I snipped some off with pliers and, with a piece of unburnt regular copper, put it with tap water in a pills bottle.
0.904V @ 1.3mA
So, that's another non ruster that would be very easy to replace or build from scratch.
