Surface area of rod

[Iotayodi]

My math skills dont include calculus and I think thats what you need for this question.

1 inch od 1 foot long rod. If you thread the rod 1/2" inch deep using the finest thread per inch. Would the surface area increase or decrease? It would seem to me that it would have a greater potential.

The idea behind it is to increase the surface area and at the same time make it a continuous unbroken helical spiral,which may or may not increase the flow of potential energy. Im wondering if different pitch angles and spacing per inch would have different potentials also. This is in reference to Earth battery systems but may apply elsewhere.
I wish I was smart enough to be a physicist!

If I understand your problem correctly then yes, it would increase greatly.

Did you want to cut it in a similar way to this...?

I agree with paradox, threading would definitely increase surface area, but you would really have to try it in order to really see if it gives a significant increase in power. I had an idea to use copper wool but never got around to it. I don't believe surface area is all there is to it, there's also mass, distance between electrodes and so on. However Nathan Stubblefield's system seemed different all together. He used coils in the ground, but the thing is they weren't used as a normal galvanic cell. I believe those were his special earth grounds for a much more complex device which could pump energy from the ground. It's too bad nobody knows how he did it. Thrapp seems to know, but he ain't telling.

Thats exactly it PArAd0X. I assumed there was an increase in surface area but wasnt sure. I may have to try this out and see the difference between 2 identical rods. I know multiple strands of wire offer more surface area so strands of twisted carbon,magnesium etc should also. But the question still remains if there is a substantial increase in potential and decrease in resistance.
Another thought is fins like in a heat sink. I wonder if anyone has tried circular or square fins of carbon with perforations (to let the soil pass through to the next fin) to see if that increases the potential. Just spit balling!

@Freezer
The mass can be adjusted if necessary. As far as distance thats up in the air for me. Ive watched various videos and a substantial increase in length doesnt seem to increase that much to me. Ive only done 6 inches to a foot and still get .88 to .97 while others have gone 20 feet or more and get the same. It seems the mid 80's to 90's is consistant on any length ive seen so far. Thats natural flow with nothing added using copper and zinc.
From what Ive read, Stubblefields coils were tuned to the earth and eventually self oscillated.
