3. Experiments radio EDI. A comparison with the Hertz waves
In the last
series of experiments we showed how it is possible to identify electromagnetic induction (EDI) with special sensor and the mechanical movement of an electrified body. Now we will try to prove that the same effect can be obtained without movement — just periodically changing the amount of charge in the transmitting antenna. However, repeat experiments with the transfer of the electric potential at a distance, which was conducted by N. Tesla, Alexander Popov, and G. Marconi. And we are talking about the first such experiments, because then the radio went a little differently, more effective as it seemed, the way and completely switched to Hertzian waves, which enjoys to this day.
For the experiments we would need a sensor EDIE from the last
series of experiments the generator (GG1 in figure 5), which can be assembled according to this diagram
(Fig. 5a), or any other generator that can operate up to frequencies of 1.5 MHz (Fig. 5b). The first will give the best results. Still need a filter, consisting of two parts: the inductance Lf and capacitance Cf, and a simple field indicator
on the led. Lf is a coil in the armor core, it is exactly the same as L1 in the last
series of experiments, and as there, for it will be very important the clearance between the cups, which may have to pick up experimentally. Read more about this filter you can read here
. The capacitor Cf can be applied to any variable or trimmer with a large range of adjustable capacity. After the filter is necessary to connect transmitting antenna AN2 — a piece of wire of length 1m.
Fig.5. Scheme of the experiment: the connection for the bias currents
The LfCf filter is designed to create maximum potential on the antenna AN2 — this will be the preparation for our experiment. When the generator GG1 by modifying the capacitance Cf, it is necessary to achieve the maximum luminescence of the indicator field when it is presented to the antenna AN2. If the experience used a signal generator, then it should be set the frequency to about 1MHz, and in the course of the experiment to find better.
The experiment consists of fixing the transferred potential on the receiving antenna (AN1). For this, it should be placed at a small distance from the transmitting — 1-2m and achieve full illumination of all LEDs on the sensor SN1. When you turn off GG1 all indicators shall extinguish. After receiving this result, the distance between the transmitting antennas and the front Desk can be gradually increased. The author of this communication has worked up to 10m.
The effectiveness of such communication can be increased without changing the distance between the antennas. To do this, as a transmission antenna, instead of the piece of wire you can connect any sheet metal the same height, for example with dimensions of 0.5 m x 1m. Then, the connection will run at the same distance, but this would require significantly less power the GG1. Thus is revealed another difference between antennas for EDIE from antennas for classical transmitters, where important area, not length.
Status and prospects
The above experiment is the repetition at the present level of the first N experiments. Tesla, Popov and G. Marconi for the transfer of the potential at some distance. Scheme first receiving and transmitting systems, all of these researchers were about the same [1,2] and contained in the sending end of the high-voltage source changing the voltage, and receiving — of coherer , which abruptly changes its resistance under the influence of an electric potential. The coherer is included in the electric circuit consisting of a power source, a decoupling chokes and relays, and closing it includes the relay and solenoid. The hammer electromagnet shakes the coherer, returning the resistance to its original value.

Using this system it is possible to transmit not only information but also energy, which Tesla wanted to provide people anywhere in the world, having built a few dozen of transceiver stations in different locations. The most interesting thing in this case to build capacity at the receiving end is optional — it already exists in the form of natural field of our planet  — he need only to give momentum.
In our days, after almost a century of oblivion, again began to think about the transfer of energy and information using electrostatic methods. One of the areas — EH-antennas [5, 6]. It appears to us, the full potential of EH-bond, which is so far only due to the special structures of the antennas here are not yet opened and for the fullness necessary to change the receiving side of the device.
In the direction of energy transfer on the distance you have to mention single-wire system [7, 8], unambiguous explanation of which physicists are still there. Such systems allow to increase the density of the transmitted current 60-70 times for the same section of the conductor, and the conductor even when streaming the maximum current output.
Noteworthy developments of the transmission of energy without wires is not conducted.
At the end of the notes we will try to make a comparative table of the two systems of transfer capacity. Of course, it is still imperfect and may be supplemented and amended in the case of the emergence of new data.
|Property ||E/m wave ||EDIE |
|The defining parameter of the antenna for the best connection ||Length that are multiples of 1/4 wave ||Area |
|Defining a parameter of the transmitter to achieve the maximum potential at the receiving antenna ||Power ||Voltage |
|Wave type ||Cross ||Longitudinal |
|Wave speed in air, m/s ||3*108 ||4.71*108  |
|The dependence of the potential on the receiving antenna in the far field from distance r ||1/r ||1/r in the particular case, in General depends on the shape of the antenna |
|The reaction of the waves on the environments tab, if its length is comparable to the sizes of obstacles ||Reflection ||Partial reflection and partial walkthrough |
|Can be used to transfer energy ||Only with a strong focus ||Maybe |
In fact, any type of communication involved both the transfer system, but depending on the conditions of the experiment may prevail one of them. For example, if the Premo and transmitting antennas, we have less to deal with the multiplicity of wavelength, but will pay more attention to increasing their active area, and the receiver will react to the change in the potential of this antenna, we get the connection mainly on EDIE. And Vice versa. In any case, this question remains open for new research and researchers, both in its experimental part, and in mathematics!
