The lighting up of the bulb at the shovel reminds me of the capacitive transformer
effects of the Testatika principle that these guys here have shown.

There they also convert the HV RF currents to low voltage high current via such a metallic plate
around the coils.

Hi Stefan. Yes, it is similar in the way that they are using a capacitive plate to pick up
the HV field from the tesla coil, and use this to power the bulb. The difference is that
the Russian guy only seemed to be drawing very low power from his power supply,
but at the webpage you provided they were powering the tesla coil with 40 watts, I believe.

  Probably won't happen until one of us here hits on it, and shows us all how it's really done.

It is less likely someone will step forward and serve us on dish all good stuff ready to swallow.
So, you must prepare you self for a long wait for this. And if someone will do such a thing it will be hard to tell if that info is of real value or not after such large amount of giberish and mistrust.

However, the idea that that device does not need to have a magnetic current circuit, along with the HV (Kacher) circuit, is of interest. At lease to me.  As I love simple circuits... that work.

What device do you refer to ?

Nick, you had asked me to try lighting some incandescent bulbs with one side connected
to earth ground with a kacher driver. I am using a different tesla coil secondary in this test.
It is a shorter secondary wire, so the tesla coil secondary voltage is lower than in the first tests
I did. This tesla coil with an aluminum plate top load is running at around 1.6 MHz.

I have a 4 Watt light bulb connected between the kacher circuit chassis ground and earth ground.
I am using batteries to power the kacher circuit, and I don't have any scope probes attached to the
circuit to make certain there are no ground loops.

In the first test the kacher was powered with a 12V SLA battery (around 12.5V under load) and was drawing about 0.3 A.
Kacher power consumption was around 3.75 Watts.
The 4 Watt light bulb was only lighting a little bit.

In the second test the kacher was powered with two 12V SLA batteries in series and was drawing about 0.5 A.
Kacher power consumption was around 12.5 Watts.
The 4 Watt light bulb was lighting fairly brightly.

This confirms that a low power tesla coil will light an incandescent  bulb with one side of the bulb to earth ground,
but even to just light a 4 Watt incandescent bulb fairly brightly to earth ground I had to crank up the kacher
input power to 12.5 Watts. This should provide you with a bit of a reference point to compare to
if you plan to experiment more with this sort of setup.

P.S.  I tried a bit different configuration and found that when one side of the 4 W bulb is capacitively coupled
to the HV end of the tesla coil, I could get the 4 W bulb to light with the other side of the bulb only connected
to a short aligator clip lead. Just the short aligator clip lead (the green lead in the third picture) is enough
to cause enough 'displacement current' in the bulb to make it light up. Kacher was powered at 24 volts.

I made my cables shorter, i added a coax cable for gate signals and things became better.

As you can see the layout matter a lot.

The waveform might be satisfactory to you now, but it still is not to me.
Do you have the MOSFET drivers glued to the MOSFETs yet ?

Please post a scopeshot of the power supply rails at the MOSFET driver's supply pins, while your scope channel is set to an AC coupling mode.  ...below 1V/div vertical scale.
