Good Morning
As promised here are the results of all the cells hooked in series including the cell with finely ground carbon. 7.63 volts.
I know for certain it can go higher with the ground carbon, but there are still other tests that need done and the granular carbon is easier to work with.So I am going to leave the others granular for now

Hi Brad
I wanted to compare your idea of incerting the wire as you do compared with using the copper tube as I do. The following are those results.
In the following picture is a single cell using granular carbon and magnesium as before. I was hoping to use a galvanized tube and thought I had one in my workshop but didn't.
The voltage results were 1.51 volts.

The following is a picture of a cell using just a single wire in the granualar carbon. Just as the previous picture I used a magnesium rod. The only other differance is I removed the copper tube and used a PVC pipe to contain the carbon and water around the magnesium rod. The resulting voltage is .35 volts.
So I have to conclude that a larger contact area is needed to maximize voltage.

Good morning again
I hope to test my other ideas later this week and post the results. I wanted to retest the amperage as well but we got the first disk of Caprica last night and wanted to watch it after dinner so I hope to have the amperage results soon.

Good morning
I checked the voltage again before I came into work and the voltage from using the wire instead of the copper tube did go up to 1.08 volts after the water had a chance to work its way through the carbon. However it is still lower than the 1.51 volts using the tubes.

Hi Bizzy regarding the wire you wrapped it around the magnesium rod? You should do a Joule thief or stingo circuit to one of these and test if it charges a 12v battery.
Thanks for the info.

Hi Guruji
Actually the wire is incerted into the carbon parallel to the magnesium rod. The reason for this test was just to compare a wire versus copper tubing for electricity production. Since I didn't use a JT for the tubing I didn't use one for the wire either.
Do you have a schematic for the stingo circuit?
Thanks
Bizzy

Hi Bizzy
did you manage to get those Milliamp readings under load

Hi Mark
yes I tried it under load and with no load.

Hi bizzy
I must have missed the MA results..or I am a real dumbass (many might agree with that)
I intend to build some up using the copper tube .
Please post the MA results (your volts are great)

Hi Mark
No you are fine...I have not posted my amperage findings yet becuase I don't trust those numbers yet. They seem too high, so I have to rewire my amp meter from my alternator testing table to verify those findings.
I hope to have those results by the weekend.
Thanks
Bizzy

Thanks for clearing up the MA question - I just checked in and have been looking for those reading since your post.  Please do build - the more people experimenting with these cells - the faster we will derive an optimum design.  This DIY galvanic battery has some potential and the longevity Bill reported with his makes this a promising effort.
Bizzy - Many thanks for the side-by-side comparison (Copper vs. PVC).  I am surprised at the difference in performance.  Makes me rethink my builds.  Since the copper will not be consumed in these configurations, the cost can easily be justified.  I need to visit the home improvement store and gather some more materials.  Hope I can catch up.  Great work and again - Many thanks.

Hi Brad
 You are certainly welcome. You are also correct in that the copper will not be consumed. So the copper tubing would just be an initial investment. Only the carbon and the magnesium, and the carbon only slowly.
Also when teh cell is not in use there is no acid only water so these cells should have a much better shelf life than other cells. The only magnesium degragation will come when it is actually producing power. And with magnesium rods that size I would think the life wold be very long.

@Bizzy
Many thanks and look forward to the results. The next thing is to see how long the Mag rod holds up. Thats why I will build some.

@B_Rads
many thanks for your posts. I looked at my wine rack and is sadly depleted. I often make wine with the local Italian community (and grappa he he) We have many fine wines down here in Australia.

My interest in this is a humanatarian project a friend of mine is helping out with in Africa...long story but what we develop here could be very helpfull
