Why is it that the cylyinder is worse than the plate?

It looked like there was more surface area in the cylinder. Could it be that the current generated in the middle of the cylinder can not escape, except at the edges? Or perhaps is it something more simple that I have overlooked?

Hi,
yes, this is a good question !
It seems you could be right, that only the outside of the cylinder will
conduct the current mostly in this case.
If you put a Zamak rod INSIDE the graphite cylinder, it gets
a bit better, so  this might be an explanation.
But in general there is also a difference in the graphite material
conducting the current !
These graphite plates are made mostly from "Blow-graphite" and
seem to have more innern surface than the graphite material
of the cylinders.

Hi
yes it is right in this cells there is a little bit strange because it seams that the current is only generated where a free flow is possible from the graphite to the alloy.
stefan is right if the alloy rod is put inside the graphitcylinder then you get more out, but you cannot reache the output as with the graphitsheet and aloy plate because the alloy plate has much more surface area as a 1/4 "rod.
dont forgett this is just the preliminary test what is only used by me to determine the overall capacity of the material and sizes.
The real test is with the cell build especially with my like stefan call's it "power powder" there the output is staggerd up to 5 times the current this is where the real value of my AG-cells comes.
I will post a seperate message in regards to all the value of my AG-cells.
greetings

In order to test 'why' and the possibility that there has to be a direct 'line of sight', I think it would be interesting if you could 'aim' the cylinder towards its target.  Then if the readings vary as the cylider is moved, it will definitely be directional.  If you can get more current this way than with the zamak in the cylinder, it might also speak to the ammount of liquid nessessary to carry a full current.

Just an idea.

Well it depends mainly on the graphite being used.
Bruce has got so far the best graphite with his cylinders,
so he gets very high voltage like 1.3 Volts in a saltwater bath together
with a Zamak rod.

Walt?s and my cylinders only give around 0.9 to 1.05 Volts.

Bruce is probably using additioanl chemical components together
with his graphite powder to scale the voltageup to 1.8 Volts,
which in my view will not last..
( but he seems to have a different opinion on that which
he will
probably have to show in his new coming products...)

Regards, Stefan.

Stefan,

My cells start out around at 1.8 volts. They stabilize at 1.5 volts. The batch that your cells came from is still generating 1.5 volts except for a few of them where the contact wire was not properly isolated with sealant.
