@ MarkSCoffman

Yes, I was too fast; concentrating on the "voltage addition" in a voltaic pile, while we seem to get a "current addition" in the Russian battery. Good thinking Mark!

See the attached drawing. I guess you see it like that? (The Russian inventor in 1918 probably intended such a hook up?)

I like the idea and will try it.

For higher voltage one would need several such batteries in series.


You are right, it is important to keep copper and zinc apart. I got problems with that when experimenting with similar piles or stacks. My voltaic pile had to be very "dry" to work properly. Already a little moisture between the touching dissimilar metal plates caused heavy corrosion and soon voltage loss.

I looked at the voltaic pile because one only needs to make a connection to the top and bottom plate. As I found, the connections to the plates are also a problem. Connection-wire and plate should be of the same metal in order to avoid corrosion problems.

Greetings, Conrad
Hi Conrad
What are you using to seperate the copper and zinc layers?
Thanks

Where can I find Jeanna’s Epsom Salt electrolyte?
Many of the members here would soak their separator material before wrapping the magnesium around the core.  Many different solutions have been tried.  @jeanna used Epsom Salt diluted in water with good success.  Various materials such as paper towel, t-shirt material, etc. have been used as the separator.  I personally like coffee filters.

BTW - the cell I posted Monday is still going strong.

Hi Brad,
At first I was thinking of using cotton. However I relazed I don't have much aof a gap between the magnezium rod and the outher copper wall. So I was thinking of using mascing tape like lasersaber did in his first video. I have enough material for 5 cells so I is my gola to set them up with various dielctrics bewteen the carbon and magnesium todetermin which is best.

Good Morning
This is a picture of my working "air" battery
Each cell is made of copper casing with a copper plug bottom. A thin layer of activated carbon at the bottom. A magnesium rod is covered with mascing tape and incerted inside and more activatred carbon is filled in. I poured a shot glass full of water into each cell and hooked them in a series. and the result is 5.96 volts.
Currently I am running an led on just 2 cells to see how long it runns.

Nice work.  Have you tired hooking it to a JT circuit?  With 5 volts I think you could light like 500 leds maybe.

Hi Bill
Thanks... Yes I just did and got 13.98 volts. I have to do some running around this afternoon and am going to pick up a string of LEDs from Lowes to see how well they do. My wife is already making plans for me to hook up LEd lasndscaping liughts for her run only by these batteries.

Hi Bizzy very nice work keep going. How much voltage and amperage per rod? If there is little amperage to JT try Stingo it runs with 20ma only and even less. Do you have a diagram how exactly done? Regarding Gravity wheel I have posted another idea should see.
Thanks.

Good Morning gruji
When I get to work I will post a diagram. The cells are very easy to make. Although I do admit I had to have my wife help with some of the tape :)
What is a Stingo?
I Looked at your other idea as well. Where exactly does the belt drive run?
Thanks

Hi Bizzy Good Morning too you too. A Stingo is a small circuit by Sucahyo  if you cannot find it on this forum I will post the diagram. It's like a Joule thief but a bit different with only one winding to the toroid. I found it ; that it charges big batteries quite well with only little amperage.
Regarding the gravity wheel that I planned is a wheel with small wheels around and a weight on their side for unbalance. To hold them on same position while turning; belts are necessary to the fixed centre.
I think this will work and when I have time I will do this. If you did not understood ask me I will help.
Thanks

Hi guruji
yes if you could post the schematic for the stingo that would be a big help.
I should have the diagram up for the cells later today.

Good morning
Here is a diagram of the cell I used. I then hooked them up in a series. Copper to magnesium. I hope to work on it more after work today and will report on what I find. Enjoy

One way to dramatically reduce the cost of the cells and maintain the same performance is to use PVC instead of copper pipe.  Strip of a foot or so of insulated wire and pack your activated carbon so that the wire is embedded in the length of your cell. 
1 day we should bury these cells in the yard and see what impact this has.  Rainwater, lawn watering, and morning dew might keep these cells juiced.  Good work!

Hi Brad
I actually thought about burying these as well. But that will have to wait. We got 12 inches of snow last night and more on the way.
I thought about using PVC as well but was uncertain If I would lose voltage due to smaller contact with the carbon.
There are several experiments which I want to do in order to tweek it and try to improve it. One idea was to use PVC.
Thanks

Hi Brad
I am thinking that the reduced surface contact between the copper and carbon would also reduce the voltage That should be easy to test later on this week. I will run two cells side by side. One with the copper tubes and one in pvc with copper wire in the carbon for leads.
Thanks for giving me credit I am humbled, but hoinestly it is everyone on this site bouncing ideas off of each other that helped develop  the idea.
Thanks
