@Iotayodi
This is probably the photo you had in mind.  (the first one)  The second picture shows that same Stubblefield large coil, alongside a picture of a coil made by a certain "Stephan of Germany".  Stephan's coil is just about the size I would love to see someone on this forum make.

Back in those days, circa 1902, capacitors were more difficult and expensive to build than inductors.  The variable cap was not invented until around 1910 and perfected around 1920.   

I am going to speculate that the layered stack on top of the old coils in the Stubblefield photos were open type capacitor banks.   They could be tuned to the coils by removing a layer or two of the metal plates and insulation between them.  Once you were close to resonance, then it could be fine tuned by external coils on the surface in series with the buried inductors.   Look at other photos of Stubblefield and the long open helix air coils connecting things together.   They look like coiled telephone receiver coils to keep things from getting tangled up.    But, it is a simple matter to tune these long inductors by simply removing coils and straightening the wire up.   So, rough tuning by removing plates of the open type capacitors and fine tuning by removing coils from the long helixes on the surface.

The large physical size of the components were probaly close to the Shuman resonance of about 8 Hz which some say is now closer to 12 Hz.
Now we have large capacity capacitors relative cheap and old variable air caps for fine tuning.   The large caps can compensate for small inductors to get the fundamental freq down to very low levels.

Oh yes, I am still around, and will be, hopefully, for a long time. 
Iotayodi:
Back when we first started talking about Stubblefield, a couple of us made enlargements of all the coils we could see in that Stubblefield farm photo.  Perhaps you are thinking of one of the enlargements? I remember you asking once before about that picture of caps.  I don't recall any other photos except the ones we enlarged, unless perhaps you saw it on another forum or site?

I have a feeling that Tishatang is correct in that the stacks on top of the large coils are open type caps.  Thanks Tishatang for telling us about that!  It does make sense.

Welcome back Tishitang. I had quit all of this business for a while but find myself back into it and constructing coils again. The coils are going together quite well. I have some really good wire materials and insulating layer materials which both make construction easy. Anyway, a few minor things I notice in construction....First, being generous in the insulation layer thickness between coil layers seems to be a good thing. As far as the outer winding (most call it the secondary), A true bifilar series winding produces better magnetic fields than something scramble wound in 'there and back again' manner. I will be taking my latest creation into work next week for some proper measurments. Resonant frequency and inductance will officially be measured on all windings in this system (the secondary, the iron winding of primary, and copper winding of primary). I work for a company that makes induction cooking devices so the project engineering leader has agreed to put my coil on some really good equipment to characterize everything. I am looking forward to the results. First, knowing the resonant frequencies would enable me to complete the rest of the system; capacitor sizing, and exact frequency to set my switching circuit. Who knows, maybe other useful information may be gleaned. I read the various links in ground antennas. Excellent stuff that plays right into this Stubblefield system. And in my opinion directly related to your earlier postings here. I have installed a ground antenna system to a radio I have in the garage and it does work quite well this way. So this is my current status these days. It is good to hear back from you Tishitang. I am getting close to testing these theories you have made. Resonance makes sense. I look forward to beating the hell out of my latest coil in this fashion. I will continue in my backwards operation of this thing. I will at first artificially power the secondary coil at a frequency, and use the primary coil like a ground antenna. My guess is that good power will be found and one that builds over time like Stubblefield indicated and the modern ground radio experimenters report. I'm after big power and the primary is obviously capable of high amperage. Doing it in opposite fashion is fine for play but limited in what it can do in my opinion. I have run them this way plenty and am quite done with doing it that way. More postings after I have coil test data. Oh, one more thing, I also remain wary of various - lets say - potential orbital type issues. Maybe more so in the coming weeks as earth passes through potential dustiness left directly in its path recently. Maybe no issues at all with this or maybe our satellites may not be to happy about it either. Time will tell.

Im going to add this.
This is an excerpt from an article about Stubblefield written by one of his grandchildren:

 Grandpa was now once again blamed by his wife of 36 years for accidently poisoning three of their nine children through inadvertencies. Neither, at the time of their experimenting with various mixtures of Pitchblende and salt crystals within their 85 farmland soil, knew it was contaminating Teleph-on-delgreen. From 1881 to 1906, the soil-coil RF antenna "hotspots" -- that made it possible for Grandpa Nathan Stubblefield to develop and patent the 1898 induction earth batteries and 1908 Wireless Telephoneâ„¢ -- did contaminate their foodstuffs and water.

 It wasn't until 1906 when their son Tesla died teething on a potato from one of the RF antenna "hotspots," -- that they realized that it could have been the RF antenna "hotspots," mixtures of Pitchblende, salt crystals and other active metals that created the healthy looking but tainted vegetable gardens. The watermelons, tobacco and other vegetation they had commenced growing and selling since their courtship in 1880, when he was 20 and Ada Mae, 16 years of age became an invitation for both invention and the destruction of a family.

 They couldn't shake the sense of dread, so Ada Mae on their 36th anniversary, 1917, left Grandpa Nat stranded. He moved his gear to a one room hut and became a stranger than fiction recluse. On summer nights, he would shock his neighbors by lighting up hill sides from his hut, with his buried RF induction transmitting coils.

One wonders what he did to the ground, the batteries as patented could not do this.

Iota:

I have read this before and some have used it to say that this was the only way his devices could work....with radiation.  My question still stands that if this was the case, how did he demonstrate his devices on the road including one performed on the Potomac river in DC?

Possibly he was trying to get "more power" by doing this on his farm.  All of us understand this desire.  I would love to take a Geiger counter over to the old farm location (now Murry University) and see what the readings might be.  If there was pitchblende there I would think the radiation would still show up today.

I agree with Bill.  Pitchblende is a "red herring" in this topic.  Hans von Lieven does not site the article that he quotes.  Therefore, it is of little scientific value to us.  Also, in the days that Stubblefield was inventing his induction amplyfing coil , a.k..a., earth battery, radioactive materials were not regarded the way they are today.  He surely would have mentioned it somewhere to somebody.  There seems to be no evidence that he told anyone about radioactive materials.

MW383:  How much voltage and amperage are you planning to use on your secondary coil "stimulation"?  Since your secondary will most likely have more turns than you primary, you will be stepping down the voltage and increasing the current on the primary.  Can you please give us some particulars of the device that you have built?  Pics also, please.
Thanks!

fathershand...My coil is nothing fancy. An iron bolt serves as the core. Wrapped around this is battery grade seperator paper (Hollingsworth-Vose, polypropylene based, water permeable, doesn't degrade like cotton). After this it is the standard fare copper - iron windings everyone is familiar with. Both 16GA. Copper is covered with a water permeable nylon weave insulation which also does not degrade. So in these aspects my coil is much like what is described in the patent. I just substituted in a couple of better insulating materials. Between each winding layer is the same battery seperator paper. I went with a thickness that was about 1/2 the diameter of the wires, so fairly generous. The paper is wound on as tightly as possible so it creates a nice smooth and firm surface for the next winding layer to sit on. And of course the windings are also as tight as I can make them. My current test coil only has 5 layers of copper-iron windings. Covering this is another generous thickness of the seperator paper. And then the 'secondary' winding is added. I went with simple 24GA insulated solid copper wire for this coil. This was done in bifilar fashion. So I wind a layer on (two wires side by side). The end of the first wire is routed back to the start of the second wire. This strategy is used throughout the multi-layered 'secondary'. I did this scheme because my testing indicated a stronger magnetic field being produced than a simple winding strategy. Stated again, I will apply power to the 'secondary' and see what I can collect out of the primary (in earth). Initially it will not perform worth a damn. I already know this. I aim to use the 'primary' in a fashion similar to a ground antenna. Let's see if these currents build like both Stubblefield and the modern ground antenna experimenters state. As far as what power I dump into the 'secondary', probably not much. 1.5V I suppose. And at some frequency that is to be determined. The coil will be attached to some modern equipment in the next several days for some general characterization. I want to run in a resonant condition. My guess is to run the 'secondary' coil at the primary coil's resonant frequency. I don't know though, experimentation will be required. So the characterization will at least give me hard data on what frequencies are at stake in all windings. I'll obviously be cheating by using modern electrolytic capacitors. I will also be initially cheating by using an external circuit to perform the switching (at frequency). One step at a time here. Eventually some of this would obviously be simplified. But for now it is the fastest way to more data. That's the plan.

On a side note I will resume my commercial induction cooking experiments in an in ground sort of scenerio. These circuits operate at either 25kHz or 50kHz, pretty high but they might prove useful. The pancake style coil will be sealed in plastic and buried in the ground. For this experiment I will use simple ground stakes placed in the field produced by the coil. Copper stake will be driven into the ground nearest to the coil. A galvanized iron stake will be driven on the outer fringes of the field. This due to the fact that this stake will become inductively heated. So keeping it a ways from the coil should only produce slightly warm temperatures on that stake. A smaller ferrous metal will be placed near the coil as well because the circuit needs to sense a 'pot' is on the stovetop for it to work. So I will fake it out with the smaller metal piece. This piece will get hotter than hell from the induction process but it will be in the ground so I will not worry about it too much. I will monitor volts/amps produced by the 2 stakes to see if anything interesting comes to light. Maybe nothing will...

I know there was plenty of mention on soil additives helping the Stubblefield designs. I am still banking on Tishitang's radio thoughts however. Crazier thoughts involve heterodyning with this system, getting to more powerful lower frequency designs, etc...One step at a time on these things too.

He surely would have mentioned it somewhere to somebody.  There seems to be no evidence that he told anyone about radioactive materials. 
Radioactivity was basically unknown when he first built the coil. The hot spots he looked for just may have been pitchblende. It was his grandson who made the statement. The properties of pitchblende werent totally understood at the time the coil was built but it was well known of its amazing properties. He still could have brought some in from south western Kentucky. A bucketful of radioactive pitchblende would start current in any coil.  But even so there are plenty of other radioactive materiel's. Radon gas is the most interesting to me just because its a gas. The Earths electric field has no choice but to pass through these materiel's. The pitchblende properties were known later to the grandson so you really cant totally discount his statement.

Is your "iron" bolt and/or wire really iron, or is it steel?  What was it's original intended use?
How many turns of the primary and how many for the secondary?
The 1.5 V that you will be using to get a response from the ground sounds too low, but I'm not sure.
Thanks

Iota:  I'm sorry, but there is no evidence for the supposition of the presence of radioactive materials, i.e., pitchblende.  The relating of that story was NOT sited, so we can't check it's authenticity.  At best it was related 3rd or 4th hand. That rules it out as being acceptable scientific evidence.

Now, we do know the properties of pitchblende as they relate to increasing electrical activity in coils, so that is a truth.  Can we apply that here?  Let's gather more real evidence to see if we can.  I do hope, however, that the answer will help us to successfully build this EB and get good results.

But there is but it just might not be pitchblende itself. There are radioactive materiel's both on the surface and below worldwide. As far as the story goes there is no scientific proof either way that pitchblende was used.
 Radon gas is a decay product of radium and thats a different matter.  21000 die each year from radon. Thats more than all the drunk driver deaths. Kentucky itself is in zone one. Here in Florida its zone 3 out of 3 and we still have it here. I know as Ive had to set out tests for it in an old cracker hotel as the facility manager. Radon gas escapes out of rocks also.
 If the telluric currents/charge is running through ionized radioactive gases then maybe its a little different than a normal "dry" electric current. The absorption of these gases in the coil body and damp cotton underground might be significant.
 Just my thoughts.

Hi MW383
Thanks for the welcome back.   Interesting how life seems to run in cycles.   Now a fresh go with new energy and perspective.   It is really helpful you will have each set of coils tested for self-resonance and other characteristics.   

Once you have buried it in the ground, it would be good to have the ability to give a sharp pulse the EB and watch the response on a scope.   Pay close attention to the ringing after the pulse.   It would be very interesting if the ringing is a freq other than the natural resonance of one of the coils.   This would help reveal a natural harmonic of the ground currents.   And, would indicate a freq to use to stress the field in the ground.   Tune all the coils to this freq  and see what happens?
Best of luck,

tish

Hey folks,
        Long time no see. i was reading a bit and i might have missed it as of late. But Stubblefield did have some form of trackable magnetic grid on the property.  Heres my logic

Discovered in murray at the cabin was a "pith ball detector array" Imagine a chess board with a buncha liltte wobbly things that would move if something outside in the associated grid moved.. Sweet intuitive motion detector. I wanna know how he did that . But what i think is relevant is that if he did lay some kind of grid system for the "pithball" aka the apparatus to hook up too maybeee just maybee the "glow" of the property was these grids giving a visible display.. If i was to venture to build a system like that id imagine you would have to have constant current running through it and then mesaure the potential difference that would probably make the assoiateed ball move . Just speculation . But theres more hear than any of us know still. Its puzzling.

http://borderlandresearch.com/book/lost-science/earth-energy-vocal-radio-nathan-stubblefield/11  Read this it makes a lot of sense with he back story the bottom paragraph references what im talking about

also

references the pith ball array and motion detection
