@TinselKoala,
Nice work! Have you measured the torque on your tesla motor of the second video? Is it easy to stop with a stick (probably don't want to get your finger in there)? Also, interesting color effect on the ball-chains. Is that just the camera or is that corona?

Thanks, all.
The Tesla Corona Motor / Turbine doesn't have a great deal of torque from standstill; but it will self-start, even though I helped it along in the video. There is a lot of inertia from the stacked acrylic disks so when it's running at speed it does store a bit of rotational energy--I wouldn't want to stick anything in there!
The little fan on the front adds some load and does push the air when it's going fast.
The color on the ball chains is just a camera effect, I think. I use the ball chains a lot in my electrostatic work; they are efficient conductors of EHV (extreme high voltage, above 100 kV) and don't bleed corona like smaller diameter wires would do--they act like thick cylinders, in other words, but are more flexible than thick wires would be.
The distribution of corona on and between the disks of this machine is very interesting. I'll try to do a video in the dark, if I can figure out the camera's settings. It doesn't correspond, as far as I can see, to Baumann's idea that one disk is "Cloud" and the other "Earth". Rather, the left and right halves of the machine have the 2 different characters.
This machine uses non-contact corona brushes for the neutral structures and the output pickups, hence the need for a little "touch" to get it started. I am experimenting with brushes made of carbon-fiber rovings to replace these brushes, that will actually contact the disk surfaces, and I think this will make the machine self-starting.

I have no doubt that this scheme already know
but if you can talk about it.

Hi leo48,

I know that scheme, but I think that is not correct.
The 'diode' for sure is not made like that.
There are only two poles on real 3kw Testatika 'diode'.
You can verify that looking very well at pictures and videos of the real Testatika.
And, if you look very well at pictures and videos, you'll see that my scheme is not so far from the real 3kw testatika scheme (my component and mechatronic interpretation could be wrong, though).

I cleaned up the testbed and fired it up to make a picture of the corona distribution.
This photo is 15 seconds at f/2.8  .
The left sphere is 5.5 inches (140 mm) in diameter.
