Thanks again for your reaction, we appreciate very much you comments and your theory of the workings of the so called ‘one wire’ Tesla replica.
Wi-tap started with repeating the ‘one wire’ experiments Meyl and others were using as a model for (some of) the ‘100% wireless’ workings, Tesla proposed. We did this to learn from this model and we compared our results.
Like you, we think that the ‘one wire’ model has another working mechanism then the ‘100% wireless’, the way Tesla wanted to ‘transmit’ wireless power via the Earth. Also we felt that the laboratory environment did not provide the best test conditions. Nor for the ‘one wire’ test setup, nor for the ‘real earth’ test setup.
The ‘one wire’ experiments we could conduct easily near our location, the ‘100% wireless’ experiments we had to plan near the coast. The ‘one wire’ experiments, up to 128 meters, showed that the power received did not reduce with the inverse square, but stayed more or less constant at 60% efficiency. We tried to repeat these experiments, with the ‘100% wireless’ system, in the same experimental conditions. The ‘100% wireless’ setup gives a positive result, at 4 meter, but at 8 meters, the power meter, the detector, fails to proof power at the receiver output.
Our reaction on your post will concentrate on two subjects.
1) In our opinion your ‘one wire’ theory doesn’t give a complete satisfying explanation.
2) In your reaction you only go into explaining the workings of the first experiments, leaving out the workings of the ‘100% wireless’ ground conduction system.
1 Let’s start with the first point and resume your theory:
The two Tesla coils, the transmitter and the receiver, connected to each other via the one wire, a cable over the ground (plane), is a closed non radiating resonant system. In effect the two resonator coils are connected via a transmission line, the (insulated) one wire over the ground plane. This explains why electrical energy can be coupled into and out of the resonant circuit.
fig 1 The model pictures not the physical structure, but shows the important variable elements in the circuit.
However, our experiments can’t confirm that the top capacitors do not interact with each other. The question whether these top capacitors interact electrically is important because it will determine the different forms of propagations of the energy in the system(s). In our opinion the ‘one wire’ system works just like a dipole, at least on short distances.
So in stead of the electric coupling of both the capacitors to the conducting ground, being responsible for the AC current flow in the wire and the power transfer, we think, at distances shorter than 1/2 wavelength, 150 meters in our case, the most likely is an electric field coupling between both top capacitors. Yes, the top capacitors will also interact with the ground plane, but the potential difference between the two top capacitors is bigger then between each capacitor and the ground plane at mentioned distances.
If not, you will have a problem to explain the workings of a standard dipole radio antenna. In a dipole radio antenna, the electric field lines originate from the dipole halves to each other.
Fig 2 how the short distance Tesla one wire power transfer works.
Most of the electric current will flow in the one wire as the “dipole halves” are directly connected in one circuit, physically and through the electric field. The potential difference between the top capacitor and lower side of the coil depends directly on the electron density and charge of these electrons in the connecting cable and the rest of the circuit.
The electrons in the cable move from the base of the transmitter coil in the direction of the other, the receiver coil, as they are charged and pushed by the electric field of the top capacitor and also pushed by the other electrons in the circuit. The receiver top capacitor is at the same time charging by the electric field originating from the transmitter top capacitor and electrons will flow towards the positive charged receiver top capacitor via the ground path. This movements of the electrons is typically longitudinal, there is no escape from the system other than at the output of the receiver coil.
To limit the profile of the magnetic field and the radiation of the system, the area of exposure of the electrical high frequent (HF) current flowing in the system is reduced as much as possible. This is done basically by reducing the radiating part of the (dipole) system, the long antenna wire. The capacitor is chosen to be relative big and the induction relative small, wound up in a coil and not as a stretched wire like a half wave dipole. So in the system the exposure of the current wave, the magnetic field close to the resonator is reduced and the electric field wave, originating from the big top hat capacitor, is maximized by the high voltage, highly charged electrons in the big capacitor surface. This Tesla coil system has a poor radio wave radiation and that is also the reason the electric energy does not leak out and stays oscillating in the resonant circuit as long as it is not converted into heat by the losses in the system or coupled out to the load at the receiver side.
At larger distances, lets say one wavelength and more, the ‘one wire’ system may work (as you state) as two coupled resonators connected by a transmission line, the power propagating along the line on the ground or at low height. It is likely that the direct interaction of the top capacitors becomes very small, but the system acts probably still as one circuit. Over the surface of the isolated one wire and ground surface, we would expect also an electric and magnetic field wave oscillating out of phase and propagated from transmitter to receiver, but also the other way around from the receiver to the transmitter.
By the way, your ‘ground plane conduction theory’ gave us ideas for some additional tests, to find out how the ‘one wire’ on a ground plane works. Building a 3 story wooden structure, is out of our reach, but we did some experiments varying the distance between the wire and ground plane. This way we thought to find some variation in the efficiency of energy transfer. We did not, until now. Here you can find the tests we performed and their results. We look forward to your comments.
2) Our second point. The workings of the ‘100% wireless’ ground conduction system. How do we explain our second test, the ‘real earth’ ground conduction connected to the coils? The setup gives a positive result, at 4 meter. So results are not fantastic yet, but hey, we started that way with the ‘one wire’ too. The question is, why do we obtain this result? Which real world field experiments can clarify the working of the ‘100% wireless’ ground conducting system? These questions are puzzling us most and fuelling our experiments.
Gary maybe you can explain also a little bit more of what you know of the working mechanism Tesla claimed about the way of propagation in the system. (in for example Canadian-patent 142,352)
Some sources mention the use of high energy pulsed power with a specific repetition rate. Tesla obtained these pulses by connecting and disrupting the connection with the input circuit, the primary coil, with high power high voltage direct current. That’s one possible route to continue our experiments, what do you think?
If you have some other ideas for tests to perform, if it’s practical for us to carry out, be welcome.
