[Overmind]

The most important thing in a power transmission like that is that it can defy the losses over distance a standard (transverse) transmission has.

I'm sorry, I am not an expert and I dont know much about but... I think, the Tariel Kapanadze work is the same or very close to this. The diference is the ground. This is a very good job and demostration. thank's AhuraMazda.

Quote from description:
"Probably you have heard about Nikola Tesla and his famous experiments. Well this is based on his wireless transmission of electrical energy, but with one difference. Nikola Tesla was connecting bottom terminal of coils L1 and L2 to ground (earth). As you can see from schematic below, I don't ground coils L1 and L2, instead I've connected copper plate to L2. So this is transmission of electrical energy with no wires. This is not a perfect solution, but it is simplest one. I would say, this is school example... Efficiency of transmission is over 60% up to 95%."

Wrong design! If you connected L2 to copper plate, same thing you should do with L1, connect it on same copper plate. "Nikola Tesla was connecting bottom terminal of coils L1 and L2 to ground (earth)" Yes ONE COPPER PLATE for both coils! First prove ONE WIRE TRANSMISION! Then talk about Tesla.
Another thing is SMALL COIL!
What is circulating power in coils? How will you get big power oscillation if your coil have length of 188m with wire diameter 0,2mm.(L=N*D*pi, your D=63mm and N=950)  That gives resistance of 100 Ohms and small Q factor! Your resonant frequency is calculated on base how long is secondary coil, for your example it is 188 m , that gives Frez=400kHz and Tesla said for economical power transmision we should use only  [25-50]kHz range.
Compare that with Tesla coil diameter of 5 to 15 meters, diameter of wire 2-3 mm and number of spiral turns max 50, not 950 !!!
How do you expect that it will work when you do not design as Tesla recommended.

One more Quote from Tesla:

see figure 35,
"In the Houston Street laboratory, I could take in my hands a coil tuned to my body and collect 3/4 horsepower anywhere in the room without tangible connection, and I have often disillusioned my visitors in regard to such wonderful effects.  Sometimes, I would produce flames shooting out from my head and run a motor in my hands, or light six or eight lamps.  They could not understand these manifestations of energy and thought that it was a genuine transmission of power.  I told them that these phenomena were wonderful, but that a system of transmission, based on the same principle, was absolutely worthless.  It was a transmission by electromagnetic waves.  The solution lay in a different direction.  I am showing you this [diagram] simply as a typical form of apparatus of that period, and if you go over the literature of the present day you will find that the newest arrangements have nothing better to show"
