Nathan Stubblefield Earth battery/Self Generating Induction Coil Replications

[IotaYodi]

The NS patent shows 5 coil layers. That's what I would do. 

The amount of layers or turns will be arbitrary as its a 1to1 coil. The more turns and the larger the wire will give more power though. You should have a low carbon steel core. 1018 or better. You want a good magnetic field collapse. Interleaving cotton can be a pain so thats why I bought cotton covered wire.

'Primary Coil' is done, 5 layers. Calling it this seems incorrect to me. Instead I will refer to it as the reciever coil. The construction went smoothly and was uneventful. The materials used made things quite easy. (Custom nylon weave insulated copper wire, battery seperator paper). Windings strategy for this coil was done in a fashion to allow high self induction like the patent eludes to. Next up is to construct the secondary coil. Another bad term in my opinion. Instead I will refer to it as the exciter coil. I'll acquire the copper magnet wire for this today. I will not be testing the reciever coil until the exciter coil has been added. Exitor coil will have to be tuned somewhat. This will require a bit of basic experimentation. The goal is to provide the best magnetic field possible around the core/reciever coil. Windings for the excitor coil to be series bifilar in nature, high magnetic field production, low self inductive properties.

Tishitang hinted at series resonance. OK but obviously I will employ it differently in my new constructon.
Tishitang hinted at multi-frequency operation (heterodyning). I like it.

I will aso be putting in an order for a nifty switching circuit. An experimenters kit that has series resonant circuit built into it, ability to vary frequency, etc... This will enable the bulk of experimentaton to proceed. Obviousy I will drive the excitor coil with this circuit.

Lot's to do here.... But quite fun!

The primary coil is bifilar.  What other type wire did you use?

Do you have a link for it Mw?

Understand. This is my construction Iron and Copper wound side by side. As far as the wire, 16GA annealed iron (bare) + 16GA solid copper that I had covered in a water permeable nylon weave. I posted pictures of it a couple of years ago on this forum I believe. It is nice stuff. I am choosing not to directly cycle my primary. This I will use the secondary for. Thus from a design standpoint, the secondary has to be tuned for magnetic performance in relationship to the core (in this case the iron bolt + the iron windings present in the primary). In other words, backwards from what many people do with these systems. Hence my secondary will also be bifilar wound and in series fashion in order to obtain better magnetic field generation. Limited benchtop experimentation will be performed to establish a few facts. After this, the bulk of experimentation will occur via Stubblefield coil residing in the ground. I do not believe in something from nothing. So into the ground this thing will go. The secondary coil will be operated at frequency. I will artificially cycle the secondary to begin with and use an external power source. This being done in order to research and learn. At some point this life support would be removed and replaced with something self sufficent to the Stubblefield coil. One step at a time for now. Maybe I will apply some modified Tishitang thinking. The primary will sit their and be in a recieving mode for an earth enhanced galvonic current. I intend on pulling useful straight DC voltage from the primary and perform heavy work with what I take. In theory...

Iota, here is the link:

I think this would be a useful experimentation tool. The price is right too.
