Single Wire Transmission through Earth

[antigraviticsystems1]

Has anyone done the single wire transmission experiment? If you got it to work with one wire, and wish to replace the one wire with the earth itself, how much voltage is required for x amount of distance from 3 feet deep into ground in order to receive the power at high efficiency?

Thanks.

That's a neat circuit you came up with. I saw the link on your video. How efficient is it?

losses are brutal, maybe my configuration is not good, however the transmission of electrical energy by a thread seems possible at least for short distances, but the losses are large

I have one hypothesis. I'm not sure if it makes sense entirely, but I'm basing it off my experiments.

If you use the tesla coil set up, you would have little capacitance at the metal spheres. You would also have little capacitance on the single wire transmitting the energy between the transmitter and receiver. In my experiments when I touched the un-insulated parts of the single wire portion, the receiver would turn off. However, when I used large sheets of aluminum replacing the single wire, it didn't matter how much I touched the un-insulated aluminum, the receiver remained on and did not lose its efficiency. I believe it was because the capacitance of the transmission wire must be greater than the capacitance of the metal sphere of the Tesla coils. Therefore I have a feeling the earth has a certain amount of capacitance so there should be a minimum distance withing the earth you must have between the receiver and transmitter in order to have efficient transmission. That is just my hypothesis but I am not sure if that is true for transmission within the ground. It only worked with the aluminum sheets and the tesla coils.

I got it working through a bucket of soil with voltage being about 91% .the same but I didn't have a working ammeter so I couldn't measure wattage. I'm assuming current would be the same since the windings of receiver and transmitter are the same with exception to them being opposite directions in winding. If the current is roughly the same then I would say about 85% to 91% efficient from a distance of 25cm apart and 20 cm deep. however when I touched the soil, the receiver would turn off. So I tested this in the actual earth ground and this time with a ground rod almost 6 feet deep and a ground plate 3 feet deep. They were about 27 feet apart. Sadly it didn't work. I'm gonna try putting another ground rod 27 feet apart rather than using the ground plate. Also my voltage was 20V peak to peak from my computer. Unfortunately I couldn't get my amplifier to work. It worked in my simulation but not in real life. I don't know why. I believe there has to be a minimum voltage to travel through a certain amount of distance. I gotta find a high frequency amplifier or get mine working so I can test this.

That's mainly a simple tuning issue. The bucket should have sufficient capacitance that you touching the soil should not have (too) much of an effect in that respect. Ideally the transmitter should be tuned to resonance with the bucket while the receiver is disconnected, then the receiver tuned to this frequency. If you touch it and it goes off the receiver is probably not in tune, so retune the receiver while touching the soil. Rather than affecting the frequency/capacitance (of the bucket and transmitter) in a big way I think that you touching it is more a matter of you "absorbing" the energy if you will so the apparent effect is that there's less power available at the receiver (although you should also pay attention to the distance between your body parts and the coils etc when you're touching this and that) - the bucket is very leaky and it's a bit too easy to get the energy to "spill over" into the receiver, so it illustrates the fact that you can see much more easily whether or not the receiver is properly tuned when you reduce the amount of power, also the importance of tuning it precisely to the intended frequency. Eventually you should be able to touch the receiver ground terminal (metal) without noticing much of an effect at all. But the bucket is only for simulating an earth, non-metallic connection and for experimental purposes as a learning tool. If something doesn't work with the bucket then it certainly won't work with the earth.

I believe it was because the capacitance of the transmission wire must be greater than the capacitance of the metal sphere of the Tesla coils.

That's sort of right but not necessarily in that way. By touching the small capacitance of the wire you are increasing it by a lot, so your coil is no longer resonating, it now has a lower resonant frequency including your body and you'll have to adjust the oscillator to match. Then it will start working again. When this capacitance gets naturally sufficiently big (without you touching it), and the coil is tuned to resonance with it, then any addition of a relatively small capacitance like your body has practically no noticeable effect*. So it's rather a matter of drowning out the inconvenient effects of any interfering small capacitances by using a bigger one than all the others combined to begin with, because they affect the resonant frequency of the coil which you want to be fixed.

*As far as it's concerned here.

So I tested this in the actual earth ground and this time with a ground rod almost 6 feet deep and a ground plate 3 feet deep. They were about 27 feet apart. Sadly it didn't work.

How well are the coils tuned etc. Power matters aside, the solution, or the problem, is the same thing as getting the receiver to continue to work while you touch the soil in the bucket. Once that's figured out, I'd recommend starting at minimal distance and then extending it. You'll probably need to retune the receiver more and more finely as you go along but I think you should find it possible to keep increasing the distance and retuning until you finally reach the limits of your setup.

Wow, thanks for the detailed reply. I'm going to retest everything today in my bucket. I don't know if it matters, but my bucket is actually a flower pot, non conductive.

Anyway, I have a question regarding what you have said. As I retune the frequency while touching the soil, does that mean my operating frequency will be lower? Or would it just mean I'm tuning it closer to the exact operating frequency of the two tesla coils as if it were connected by a single wire?

I ask because if one was to send power through the earth at a far distance, then your operating would become lower as your distance increases. In my opinion I think that would make things easier if the operating frequency was lower.

But now I have a conflicting thought in my head. You mentioned I should tune the transmitter to the bucket of soil and THEN connect my receiver. How do I indicate the transmitter is precisely tuned to the bucket. The LEDs at input light up at a large range of frequencies. Oh but maybe it will only light up at a certain frequency once in the ground. I will have to test this out.

Thank you once again. I will post my results. I have joined a forum here where everyone talks about this tesla experiments and longitudinal energy and what not. Maybe you will find it interesting: Topic: Longitudinal Electricity Transmission Through the Natural Medium.

Yes that's good, the pot shouldn't be conductive. I also forgot to mention a ground plane 3 times the diameter of the coil about 60cm below the coil could help, connected in parallel with the bucket so the whole thing acts as a grounding system to minimise stray/floating frequencies as well as allowing you to do various transmission experiments with the bucket. The ground plane can just be a sheet of tinfoil etc.

I watched your video and I noticed the receiver (I assume?) stays on when you touch the metal rod to pull it out of the soil. If that's the case then I don't know why it would go off when you touch the soil, but stays on when you touch the metal. My experience is the opposite. Touch the soil and retune it and see what happens. Also you should try to keep as much distance as possible between yourself and the coils when you're touching things in general, or for example if you're touching the bucket then you don't want to be anywhere near the coil or especially the top capacitance because the physical positioning of the whole thing will have a much bigger effect than normal and then you will be dealing with a different phenomena or problem, not the original bucket capacitance issue. So things like that can cause a lot of confusion.

I don't see why the operating frequency should become lower as the distance increases?

But now I have a conflicting thought in my head. You mentioned I should tune the transmitter to the bucket of soil and THEN connect my receiver. How do I indicate the transmitter is precisely tuned to the bucket. The LEDs at input light up at a large range of frequencies.

LED is not a good indicator here. You can use 1.5V grain of wheat bulbs on either or both ends of the coil but they may not light easily/at all powered only from a signal generator. You can also hang a scope probe near the top end of the coil and look for the highest amplitude, or use an analogue voltmeter. You don't need accurate readings here only relative readings to be able to tell when it's tuned.

This is the tuning setup given by Eric Dollard:



Equivalent for scope:



I use the PCI card metal backplate as the pickup because it was convenient but you can use whatever you have. I have a collection of small apple pie tins that get used for such things.
