Back to the BTG: the way that the E-field energy is transmitted to the output coil seems to be thru the nearfield, which is a scalar wave. The latest test indicates that the most efficient receiving coil is the one according to this schematic:
I have tried the Grenade coil as by Kapanadze, it also performs well, but not as good as the above one. And using the completely cancelling coil setup, there is virtually no reception. In the comparison of this three different coil configuration I have used the same wirelength (electrical antenna length) which was for the TX side (kacher): 34.7 mtr.(quarter wavelength) And the RX reception coil: 23.13 mtr. , Which is approximately 34.7*2= 69.4(half wavelength) / 3 = 23.13 mtr.(third harmonic).
I have planned to make another test with a fundamental wavelength reception coil with 69.4 mtr. length.

I did a test with the RX coil corresponding to the half wavelength of the fundamental frequency (69.4mtr). I had only a 0.5 mm2 wire at hand, the output has slightly increased, despite of the thin wire gauge. The insertion of the copper pipe also gives around 30% more output. When the coil terminals are swapped referred to the schematic, the cancelling half connected to the ground, the light bulb barley glows. This information should be useful to rise the potential of a coil by injection of an E-field. It is in accordance with the hypothesis of the different impedance of the coil sections.
Some thoughts that I wanted to share. In these systems (BTG)it has to be very clear, that only mixing two waves of different frequencies will not add additional power by default. There are at least two conditions necessary to get: the modulation of the HV wave has to be in phase with the lower frequency oscillation, and very important, only one polarity of the former have to be applied. Like Ruslan explained, "we need only one half of Tesla, otherwise she will take away what she gives"
There are different scenarios possible to achieve this, if we stick to the schematics, it seems that the rectifier stage on the output would allow only one polarity to be received. But other ways seem to be possible. Specially I was thinking to apply a DC offset voltage of aprox. 1/2 Vpp of the TC output, in order to shift the AC sinewave into a pulsed DC working point. In the beginning of the research, I also considered direct rectification of the TC output, but tests have shown this very difficult, at least with a reasonable efficiency. Another way would be to charge a capacitor with HV, and use a spark gap, the discharge would give a unipolar pulse. This is what Kapanadze did, but the coil where the pulse is injected need to have a strong dampening factor, otherwise it will turn into AC cause of the oscillations, and the asymmetry will be lost. So, in the coming experiments I will try to figure out the best way to implement unipolar pulses to the system.
