Sweet
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 B_rads about the cell you're mentioning so you don't use magnesium rod? Just PVC; carbon and copper wire?.
Thanks.

The sacrificial anode can be a metal of your choice.  I like zinc because it is soooo cheap.  Bizzy is using magnesium.  I suspect aluminum could also be used.

Hi Brad
Yes you could use any metal for the "sacrifical" metal as long as it it differant than the primary component which is carbon. However there is also work being done with same metal batteries in another thread as well.

Check out this link:

I posted this about 3 years ago on the earth battery topic.  This chart shows that it makes a huge difference what metals are used.  This is why I chose magnesium and carbon a long time ago.  They are the cheapest and easiest to get metals that give the most difference.  I frequently get over 2 volts from my earth battery which is still running after all of this time.

I hope this helps.

Good morning
The following are the results of my latest test. I wanted to know if granular size of the carbon made a differance. Below is a picruew of a single cell with activated carbon just as you would buy it at the store.

The following is another cell with the carbon fiely ground. Although .08 volts may not seem like a big differance, it is an increase. And the water is still settling into that cell.
When I pooured the water into the granualr cells the water went down easily. However in the case of the fine ground carbon it is taking much longer to filter down. I am hoping by this evening it will be full and I can get better readings.

Good morning
I discovered an error last night. When I was originally setting up the cells my wife came in and I forgot to add water to the last cell which by itself was not producing any power. So as a result my original readings of 5.9 volts was just for 4 cells not five.
Each cell individually produces bewteen 1.49 and 1.52 (not including the new cell with fine carbon instead of granualar) If water would have been added to the 5th cell the power would have been much higher.
Just to prove this I hooked all the cells in a series this morning before work. In this I also included the new cell and I was getting 7.40 volts.
The new cell individual output was already to 1.61 volts. I will have more updates tomorrow.

Nice work man.  Those are some good numbers.  Are you getting much mA's?  Those are great looking cells.

Hi Bill
thanks! I tested for amperage once but was not sure the number were right becuase they were so high. So I am borrowing my freind's multimeter this evening to verify what I found. If it is correct (which I hope but doubt) I will post those results as well.
I also want to test three other types of dielectrics in these cells. cotton clothe, paper(coffee filters ala Brad) and thin plastic.
After that test I want to test using just wires instead of copper tubes for as Brad suggested.
Finally I will convert all the cells to the best results of these tests as well as the fine ground carbon. This should hopefully give me an optimal system.

Good morning Bizzy - very impressive!
See below for the PVC we talked about yesterday.  I was out of conduit so I used threaded rod instead, I much prefer the conduit.  Let's share numbers: Open circuit voltage for two cells (2.25v).
Voltage with load (1.5v).  Amperage while running fan motor (165ma).  I would think your amperage would be higher.
Keep up the good work!

Hi Brad
You have a very nice set up yourself! I hope to test your wire idea versus my copper tube design either today or tomorrow. So we can start comparing our results with a less variables.
As afar as amps goes I do know I am producing more just by the fact that I am using magnesium and carbon but like I mentioned I don't trust my readings enough to actually post them yet. I'll just say that it is not in milliamps. :)

You've got me excited.  I am not very confident in my reading sometimes.  When I doubt my readings I use 2 multimeters (1 analog, 1 digital) for verification.

You just reminded me, that I have an analog ampmeter on my alternator testing table. With a little rewiring I may be able to use it it to double check my amp readings on my multimeter.

Hi Bizzy and B_rads very impressive work you've doing nice nice. Is Charcoal same as carbon?
Thanks

I beleive that charcol is a source of carbon but not very good. Coal would be a better source of carbon and have been experimenting with that in my earth batteries before the snow arrived.
