Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[Pirate88179]

@ Joe:

I think everyone missed it except you.  You should be proud of yourself!!  Hans suggested early on that Stubblefield did not reveal all in his patent, and, as it turns out, he did not.  You put it together.  Nice going there.

My spike is now covered completely with cotton.  I cut a strip and stitched it together with cotton thread.  No metal is exposed.  Now come the decision time.  I have some .062 dia. nylon cable (think thick fishing line) and I like Hans's idea.  But, what if it makes a difference to have the cotton in between which would hold some moisture?  I was just now thinking that I could use cotton thread.  I could wrap the copper wire with it as I go. (barber pole style)  This would take a long time but might be worth the extra effort.  Any thoughts on this before I commit?  I thought about trying to use my cotton material but I don't see a good way to do it.  My material is pretty thick (socks) and I am not sure if I could make it work to wrap the copper wire with it.  Also, I guess I could use the nylon line and later, go over that part with the cotton thread.  Best of both worlds maybe?  I opened another beer and am ready to wind.

Anyone who has any thoughts on this please let me know soon. Thanks.

Great job Joe!!!!

I did the same barber pole wind accept my strips of fabric were about an inch and a half wide and say 10 inches long i should have used something much longer so i didnt have to tape as many joints but i would recommend using long narrow pieces of fabric barber pole style Just tape your first peice down about 3 inches o the copper to leave a little for the top and start twisting that fabric around the copper. once done secure at other end with tape.  after youve insulated it by itself take the top of the wire where you taped it initally and put more tape over that joint and put the iron wire next to it so as to secure them together.. once done with that secure that joint to the bolt on a part covered in fabric remember nothing touches.. then you can wind it around the bolt much easier and not have the top be all flimsy and have to hold it.. you have the general idea tho dont worry about the thickness for now . i got by with garden glove fabric and it still worked looks liek a wad of mess... but she worked  just remember once you get a whole layer done meaning top to bottom to insulate that from the second layer of wrappings and third if ya get that far.. i only had one and half layers... not much at all so anyones is probably going to be better than mine... i just wanted to test the principal once i got it.

@ Joe:

I understand.  Will do.  I was thinking that since this is basically a primary winding, is it more important to have many layers?  Or, are we just dealing with the total length of the wire would would translate into surface area?  I think I have enough materials for two layers over 10".  My spike is 12" long but I saved a little at the top end for connections if needed.  This is great Joe,  We will see what happens.

Yes eventually after our first test models , many many winds on the primary would proportionally produce a much greater secondary current to a point. Not sure of the curve yet but i do know the speed we run the spark gap or interrupter at is going to have to be tuned to rpm's so folks in the group can replicate easily . Eg When we find our peak output on the secondary we coorliate that speed to freq and will be able to do equations to find our potential results. This  will make the later stages go much easier.

@joe, I have all the ingredients. So, what is wrong with silk? It is kinda nice to have an excuse to touch it.  

From my ceramic machining days.......ferrite is fe2O3, iron oxide.   a ferrite bead is like you would find on a circuit board in a toroid shape with copper wrapped around it. 

Thank you for this info.  I bought some tiny chokes in my last order but they don't have the right shape. I think Joe told someone to take apart a disposable camera for the flash part?
Joe is that right? I guess that is cheap enough. Too bad to have to throw most of it away.
I bought one of those wall transformers the other day thinking I would get a ferrite toroid from it . It is put together so no one can take it apart. I could try that again, but I think they are too big for a joule thief, anyway.

Tesla's fingerprints are all over this.  I truly believe that he and Stubblefield were much more than just acquaintances.  Hans has alluded to this many times also.

I agree with this too. Now that the thing makes sense many things are clear. I have learned so much in doing the things related to this earth battery; way more than in that so called electronics class.  

OK I guess I will go and wrap!

Yikes everyone is writing at the same time!!
I think the cotton thread is a good idea, button thread something thick.
I also think from many times repeated in the patent that it needs to be wrapped very closely. The magnetic field needs it to be able to form from the primary. He doesn't say but he repeats in every point of the summary that it is closely wound.
Mine looks a little like joe's and I am going for closely wound. I have only 25 ft of copper wire unless I splice it which I think is not to be done, so for now I will be going to the end of my copper.
I better post this or you guys will write more!!
