This video is similar to Avramenko's fork. 
No specific measurements of input and output power and energy are provided. No comparison with existing high-voltage power lines in the form of real data.
They must have been wrong. They would not be able to use a wire with a thickness of 8 microns, since such a wire would be torn from any movement or air flow. Commercially available standard wires have a diameter of 0.08 mm.
 It's actually a very thin wire. But it is 80 microns. Such a wire can withstand current up to 0.025 amperes. At a voltage of 100 kilovolts, 2 500 watts will pass through this wire without overheating.
Well, or a few times more if you do not pay attention to heating more than acceptable, which can damage the insulation, which in this case is not relevant.

G-line - a type of waveguide, rather than a wire in an electric circuit

we see wire  covered with enamel.
That 2D(two dimensional)  space between   wire  and enamel that for us doesn't look like space  it is a highway for EM wave to travel at  very specific  conditions.
wire is conductor  enamel   is dielectric = interface= waveguide requires conditions of https://en.wikipedia.org/wiki/Goubau_line

This wire acts as a waveguide.
Current doesn't go  inside of the wire .. it means... the electromagnetic wave goes along the wire
....the same is with  lightning, ..if the lightning  would  go inside of ground wire  there would be no wire .....

Here is a  video of Russian  butcher  who made me angry:
