I intend to investigate displacement current as a power source for field propulsion.

for this a DC high voltage Saw tooth wave needs to be created.

I used coils to produce impulses, but these produce equal and opposite polarity displacement currents.

So the best solution is to use a HV capacitor and quenched spark gap to discharge it.

the capacitor surface area will produce the displacement current, so a special capacitor needs to be formed. a large flat surface is preferred, or a slightbowl shape to focus the displacement.

also the spark discharge must be dc. to prevent voltage reversal a magnet might be usefull.

A strong ground connection is needed to handle the strong changing voltages.

it will prove Aether has inertia, which means we can push or pull against it.

a zvs with flyback coil could be used to produce dc high voltage in the capacitor.
Or a AC source with diode/capacitor combinations to step up the voltage
but that might charge to slow after discharge.

the capacitor should be placed in a vacuum chamber to avoid ion wind, and should be able to move freely, hanging from thin wires.

it then should be able to move.
this is what Thomas Townsend Brown probably also did.

the capacitor should hang from its wires, and the wires should be twisted to prevent interaction with the magnetic field of the earth. As the high DC discahrge currents move through the leads.
the wires should be long enough to show the slightest movement of the capacitor
the force from the displacement current, is perpendicular to the surface area of the capacitor plates, so the lines would need to be at the right angle for it to work

I tested the temperatures of my tungsten spark rods, and yes they rise.
used a ZVS with flyback into a microwave diode (passing positive) into a 10kV 3.3nF ceramic (cheap) capacitor bank.

While sparking the infra red Seek camera quickly stopped recording, but it did record just long enough to see the temperature rise on the rods.

Need to compare it with negative voltage. but flyback wont do this as it has an internal diode.
Will try to convert a violet wand, to get the high voltage AC, and rectify it to negative voltage DC spark.

the cap bank needs to be replaced, as it smoked... cheap stuff...
still got some proper caps , so that will be more fun.

I've drawn out the circuit of the violet wand.
it has a PNP transistor that is nameless.
100K over the AC input, maybe for interference dampening.

it uses a 91k pot, parallel to a 47K resistance to limit the power. the pot also has an in/off switch.
these then are in series with 2x75k ohm which are in parallel, and A 1uF to the other AC lead.

there is no ground, the secondary probably is connected to the primary, which makes this pretty lethal if you ask me.

its a 110V unit, which was sold as a 230V EU unit (got my money back due to this!)

lowest pot setting spark is around 1.1cm length and pretty noisy

higher pot setting is somewhat larger in distance 1.5cm sparks, but doesn't become longer than that.
only the noise of the spark increases.

better keep it at the lowest setting.
the sparks also produce a lot of ozone

edit: I thought that diode was wrong, but printed circuit confirmes, stripe is on the transistor side.

weird! out 1 and 2 are I asume the primary. But there is no connection to the secondary!
So the secondary is floating on one end?

edit 2: I made a mistake in the schematic, I'll remove the wrong one (C1 misplaced)
I seriously wonder if I have drawn the symbol of the PNP correctly

the secondary isn't grounded, so it won't pass through the diodes into the capacitors.

I think it's time to use the circuit for a custom resonant coil.

but I rather use my own radiant circuit as primary, as I can tune it perfectly.

then I can use the impulses to excite the secondary.

I never did build a regular resonant coil, what these days falsely is known as a tesla coil.
but I was gifted a secondary so why not use it!

I figured out that I should be able to reverse connect my flyback transformer (with series diode build in) to get negative DC high voltage DC.

And yes it works. So now I could compare the sparks of positive and negative DC, something I wanted to do for a long time.
both are loud, both have the same colour, both make the tungsten spark probes hot (I made a recording with infrared camera)

But... I also probed the highvoltage, to see if the triangle wave was good. and yes, not bad.
But clearly it can be seen that the discharge doesn't stop at 0 volts, but becomes positive.
This might be due to the poor earth ground (I used a thin low voltage wire to ground the probe).

so room to improve. And maybe this also might be fun with a strong magnetic field in the spark gap, to prevent polarity reversal.
very glad to see the triangle wave.
 
white alligator clip is for safety, is removed, when discharging

I've made a new sparkgap, with tungsten rods.

I first made a 1mm gap, which gave 72kc/s sawtooth waves. scr01

I realised, the wave din't need to be DC, aslong as the displacement current induced was unidirectional.

I increased the gap to 3mm, which made the spark purple and soft, and the wave form more sine wave like, with much lower voltage. scr02

Thus I increased the capacity by parallel adding 3x10nF in series. This made the spark white again ,and very loud. at the much lower frequency of 3.5kc/s Now the wave form is as I want it to be.

A slow rise in voltage, with a fast drop. scr03

But the added 10nF 3kV capacitors are cheap blue chinese ones, which heat up very rapidly. I can't spark for long times, or they will burn out.

So, I will need to find more proper ceramic caps. which are larger, so they can handle the huge discharge currents (heat).

yellow is the HV probe on the spark gap, the black aligator is for safety, and removed when sparking

I attached 2 parallel plates to my 8kV sawtooth at 3.5 kc/s

they have a capacity of 250pF
and are hanging loose above the ground.

I put the system on and off at the frequency of the swing.

as can be seen in the movie, it starts swinging.

This is due to the unipolar displacement current from the fast discharge through the sparkgap.

A possiblity is that the magnetic fields of the wire could be playing a role, but for now I am happy with this first result.

could this work?
no earth ground is used.
