Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

No cap is needed the wires are the cap when wound in a bifialr fashion.  And all that is needed to transform this device to the "self sustaining electromagnet" it to connectet permentaly the leads 5 and 6 from the cell terminals 10 stay open and in the groun to preserve the character of the electrodes.  This creates a permenate electromagnet.  Not what were shooting for tho , im working on perfecting the "Self Generating Induction coil " the second device in the patent.

I am aware that   the patent  says  that  nothing  is connected to the 10  leads to preserve  the  charactor of the coil ......   In my opinion  that  does not mean that ANYTHING  that is connected to the 10 wires will change the charactor  of the coil .........although  I would  agree that most things connected to  those leads  would change the nature of the coil .           A cap  would not  be  taking  anything  from   the 10 leads ......only allowing  a different  flow of energy .

I am not asking   anyone  to do anything  with  these ideas ......just thinking out loud .

In general  I  don't like the idea of   mechanical  contacts .     remember changing  the points  on a car?    Electronic ignition  is MUCH  better. 

If the  electromagnet  can be made to  self resonate it would  much more reliable   than if it had  a machanical  contacts 

My  guess  is that if it can be made to resonate it  would  have the same average voltage ..........but it would  have a spike at the resonant  frequency  that  could be used to drive the secondary .

I understand what your getting at.  Some properties of this coil are different than normal for instance it has a strong magnetic feild not even moist.. jeanna found this out we dont know what to make of it yet. 

Anyways   I belive when the device is configured as an electromagnet it serves as a base station wireless transmitter.. Only logical conclusion after the patent states that a microphone or telegraphic relay can be hooked to the secondary terminals also states to connect permentatly wires 5 and 6 for this config .

   Then a few sentences later it says that a secondary current will induced in the secondary coil when the make and break happen at terminals 5 and 6.. It describes earlier in the patent that in this con fig the terminals 5 and 6 are hooked to a device which interposes them.

These statements are contradictory unless you assume the patent describes two devices. plus on the last page in the patent you can see the two summaries second collum.  Tell me what you make of this, im more than willing to chat on skype or msn if anyone wants a to chat to further this effort

I reread  the patent   early yesterday

It  did make alot of difference   understanding that it  was about  2  different  configurations of the  basic coil.

The  way it is worded it is not clear at all that he is actually  describing  2 setups .

Great catch     


I think  Stubblefield   knew  there was something different about the coil .......I am not  sure he  could explain it.
He  called it a couple   a few times ......I think he was  thinking along the terms of  a thermocouple

I remember in  one of the  TPU threads   someone   was trying to explain  that  magnetic  fields are attracted to iron.  The  concept  didn't  seem to go over very well .     I think it is true though .   
If it is true  it would explain   why   this  coil  can  hold a magnetic charge even when dry .

Hi everybody,

I went back to those 2 calculators today, after some sleep. The problem with the numbers from last night was the resistance. I already have 1 to 1.6 ohms -NOT 100milliohms.
So I plugged in 1.5 ohms and .7V since most everyone else is getting .7 volts, and I just changed the C and L sliders.

So somewhere between
500uF-599uF and
300uH-350uH
will produce 50 - 65 Hz

I live in the US so 60Hz is the most convenient number. Since I am going through all this I figure I might as well make it easy.  

So, the next thing to figure is How many turns, how fat and what gauge.

So, 360 turns of 24 gauge copper over a diameter of .85 inch will give 308uH
or,  360 turns of 24 gauge copper over a diameter of 1 inch will give 423uH

I used that telephone wire along with some zinc plated iron to make those  dry test coils. They fit well and 360 turns was do-able using 100 ft. It was 60 turns per layer 6 layers.

I am posting these numbers to give anyone who wants them a place to start winding.

One thing I saw on the RLC calculator is how easy it is to get to a very high frequency and how the graph goes below zero oscillations before it gets down to 60Hz very readily.

The resistance jacks the oscillation rate to the KHz range very quickly and so the fat wire that radio guy mentioned is not so hard to believe after all.

Now the only problem is to get the bolt diameter to work. .85-1 inch diameter I guess average.
I am wondering about using a piece of steel pipe then maybe filling that with iron wires or something to make a solid iron core.

@Joe and Gary,

The cap will help us tune this. In fact, I am going to look for a variable cap.

I know I said it a while ago, but I asked Hans about a spherical capacitor and he said theVandeGraf sphere is the cap part. I can easily see the sphere enclosing the terminals 10 and the spark happening inside the sphere. The sphere would keep the thing dryer and safe from movement, etc.

If we time the turns and diameter etc, we may not need an externally driven relay switch at all to make the make and break. It just might be a part of this design when it is tuned.

I urge people to play with those calculators.
One shows the Hz and Henries, the other shows the turns and wire gauge needed to produce the Henries.
