SvenThe capacitor experimenting is very interesting indeed.You know, I ws making capacitors a while back, and found it ridiculously easy to make very good capacitors from cheap common materials.How about polyethylene sheet plastic and aluminium foil? How cheap can you get, along with spray adhesive, hot glue and some scraps of aluminium wire for tig welding. Oh! I forgot, empty toilet paper core tubes hahaha. They work great, even for 10,000 volts without flash over. They are not tiny little packages by any means, but you can make them any value you want to, just more surface area, and a bigger or smaller roll.I have news regarding my daisey chain bridge rectifiers and big dc motors.I have been running the 1.5 hp dc motor that is currently driving the 100 lb flywheel because I am too lazy to take it apart. It is also driving a little 40 volt fractional horsepower dc motor with a vee belt none of which is directly part of the experiment, except possibly as a load. I am running it using a variac and bridge rectifier at about 11.2 volts.Just inserting another bridge rectifier ac Now I am working these big motors way below their rated hlegs down between the two brush wires of the 1.5 hp 90 volt motor( running on 11.2 volts) yields 12.4 volts dc !Interesting! However, I noticed a slight jump in the line amperage required of half an amp using a little automotive 12 dc motor. When taking that connection to a big 1.5 horsepower dc gearhead motor with a 10:1 heavy gearbox, there was zero rise in amperage, as opposed to the little automotive motor.l am running these big motors way below their standard voltage.I have noted the voltage increase, and now the zero feedback to the source amperage.If you have any largish dc motors, give it a try, as I think you have everything in your test room.It is not fancy, or in anyway difficult to do. I have yet to flip the ac leads back and forth to see if it makes a difference in performance regarding the second motor, and system amperage draw.Cheers Warren

I found something interesting and wonder if this is relevant.
Capacitor Capacitance is reached by the size of the plates, that will be clear to everyone here, but the distance of the plates also has a strong influence on it I would not have thought now.
In tests the distance between the plates is increased and the voltage increases and vice versa the capacity. I had not thought of that.
I always wonder if it's because of the capacitors we get today which are much more compact and smaller than before, maybe the dielectric is so thin that the gaps between the plates are so small that the new capacitors do not produce the same effect as the old ones , The old capacitors certainly had much larger plates than the new ones at a greater distance to achieve the same capacity. I may be on the wrong track, but I think you can think about it.
I was able to get 4x 10μF capacitors from old production and withstand the 3.15kv and in relation to the other capacitors I have huge.
I want the transverter with max. Drive impedance and make the connection via small coupling capacitors to the diode plug. Perhaps one could tap the earth into the resonance system via a diode. I wanted to protect the diode connector with several suppressor diodes in series to short-circuit if more like 1200V are transmitted.
I always have to think about my high-voltage test where the ground connection could trigger the spark gap faster. Unfortunately, I could not measure any voltage or no devices that can stand it.
