I have made the setup again, now with the DC offset module, to create positive DC on L3, using a 1.3uF 4kV cap to ground on the L3 outside rim.
DC generated as usual from the negative impulse

what if I gave L3 a dc offset.
and tuned it to L2
giving loads of current in L3

then use L4 as a grounded cap plate.
inside between L3 and L2,
and make L4 tuned to the L1 impulse

tuning L4 to the impulse was best.

And let L4 ring by itself but coupled to L3.

and using the dc of L3.

I need to get that displacement current of the earth cap plate moving some how.
make it feed into L4 and L3.

DC offset on L3, L3 grounded by L4

 we know that a longitudinal tsunami wave can move at a speed of up to a thousand kilometers per hour, but energy is not spent on its movement.
because when it moves, energy is transferred, and not material particles of water.

I wondered how these waves could travel this far and not loose energy. They act like ring toroid vortex

I take a very large self-induction and a relatively small capacitance, and tie them together so that no electricity can leak out (radiate out). I thus get a low frequency; but, as you know, electromagnetic radiation is proportional to the square root of capacitance divided by self-inductance. I don't allow the energy to come out; I am accumulating tremendous energy in this circuit. When a high voltage is received, then if I want to receive electromagnetic waves, I do so (radiate), but I prefer to reduce these waves in quantity and transfer the current to the ground, since the energy of the electromagnetic wave is not recoverable, while the current from the ground can be completely recuperated (returned), we kind of load energy into an elastic system.

That's Why I use a large capapcity for L2, it has mainly current in its resonant energy, voltage is barely there. the characteristic impedance is tuned to the magnetic field side.
When now the impulse is available on L2, it creates the displacement current, which Tesla calls the electro magnetic radiation.
This energy radiates out, and would be lost, if not the L3 secondary coil was there to capture it.
L3 is tuned to this radiation. as it acts like a capacitor plate equal in size to the L2 coil/cap

L3 resonant freqeuncy is matched to the impulse half wave. Thus is rings high in freqeuncy from the impulse. from the radiation that is being captured and transforemed into high resonant currents.

L3 captures this energy that is radiated by L2.
And it thus is needs to have a small capacity, so it doesnt radiate away. and I have seen this work already.

Now, how is it transferred to the earth? That still remains a mystery.
But what if the energy is being rotated ,pumped around L3 and L4?
pumped in between them?

I've been wondering If I connect the outside rim of the series resonant L2 primary, directly to the positive voltage supply.
But, then it cant discacharge when the mosfet is on, as the diode only passes one polarity.

should there be a third line on scope? the one that  gains the imparted impulse?

I have no idea what you are asking

Page 23...

L3 and L4 should be able to create a constructive feedback loop.
by their magnetic and dielectric coupling.
using parallel series resonant mode.

L3 is excited by the impulse, I will not tune it down anymore by C3.
thus L3 will be high in frequency. L1 impulse must match L3 for excitation.

L4 is series connected to L3. but with a cap inbetween L3 and L4. this will extend the capacity of the L3 and L4 coils that are coupled as capacitor plates.

so magnetic close coupled and dielectric coupled.

energy flow should be circulating from L3 in to cap into L4, and magnetic between L4 and L3 back again.

I would prefer to start with an equal size L3 and L4 coil.

L4 is grounded, L3 is not grounded.
the cap between L3 and L4 serves as ground for L3?

Back to testing!
After building a Tesla coil with impulsed  primary. video is recorded and edited!

tsunami is not moving water
it moves energy through water

displacement current is not moving Aether
its moving energy through aether

they are energy waves.

does this mean energy can circulate around the coils?

yesterday a photo from a few years back popped up, a screenshot of my scope.

it showed the  L2 voltage sine wave, which jumped down in voltage!

I didn't realize it immediately.
later that day I asked for help (to the universe) before going to sleep as I often do.

the photo popped back into my memory.
and I realised, I had a sudden single change in voltage! thus a single displacement current!

I remember this was done by making the L2 tuning cap smaller, and tuning into full resonance.

this raised the frequency, but this was lowered by L3 making it's parallel cap big.

L2 cap was discharged by the impulse, thus the negative impulse was tuned to the L2 positive voltage maximum.

This makes SO MUCH SENSE!

Will build the setup again, and tune for tgis effect so I can show and play with it.

I found the photo and added it. It wasn't as I remembered. Right now I am trying to set it up like I want to. Still figuring out if it is possible

to get the cap (the cap is series resonant with the primary) discharged by the impulse, the impulse must be the same frequency as the primary coil.
But it is phase shifted  -90 degrees, so the impulse negative maximum, is at the cap minimum.

So with equal L1 and L2 coils, it would make sense to make the C1 and C2 caps equal in size. and small.
C1 being parallel to L1 and C2 in series with L2.

By keeping them small, the voltages will be high, which is needed to interact with the ambient medium.

The impulse is tuned the the L2/C2 positive voltage maximum, so it can be discharged.

displacement current is longitudinal energy flow.
so aether is pure energy.

If I can make a vacuum of energy I can get an inflow of energy from outside.

So, I will again use positive dc on the L2.

L3 will be high frequency matched to L1 impulse.

after stepping away, to look at another unfruitfull project, I am back at it.
again with the L4 in series with L3
L3 parallel tuned with around 11nF
L2 series tuned with 61nF
L1 parallel  with 9x68pF to slow the impulse down from 180ns to 283.2 ns (which lowers the voltage supplied, and increases the current supplied, not ideal)

This time to tune the L1 impulse (super imposed on L2 primary) to L4 extra coil again.
L1 L2 close coupled, L2 L3 loose coupled (15mm) L3 L4 close coupled.

L1 at first was bifilar, but I could not see L4 rippling, which I needed to measure its frequency. So I can make L3/L2 a sub harmonic.
So I made L1 unifilar, which made the impulse much faster. Now I can see L4 rippling again, because for this to work,. the impulse needs to be faster than L4.

scope shots are from this measurement. F=155.5kc/s

Then I remembered, again, I already had tuned the L4 and L1 coil to perfectly match.
So Now I need to make L1 bifilar again. and tune L2 L3 to the L4 subharmonic.

scr208 shows in yellow the L2 with impulse (and ring because the impulse is too fast)
scr209 shows the L4 ripple frequency around 1343.63 kc/s (728ns)
scr210 show L4 half wave=388.8ns which the L1 impulse should match (or be quicker)
scr211 shows L1 impulse which is now 283.2ns  so it is faster than L4 which is good. but I needed a lot of capacity to slow unifilar L1 down, this is with 9x68pF in parallel to L1

From My earlier test today with the bifilar L1 I measured it to be around 380ns (from memory) I will measure again when resoldered.

L4 subharmonics:
8th=167.95 kc/s
9th=149.29 kc/s
10th=134.36 kc/s
11th=122.15 kc/s
12th=111.97 kc/s
13th=103.36 kc/s
further down it will because a bigger error, due to the measurement error of L4 ripple.

L1 is made bifilar again, slowing down the impulse to 379ns which equals the half wave of L4 measured in previous post.

I tuned L3 to the 9th sub harmonic of 147kc/s This is still rough, as calculations are not reality.
L3=19.6nF (increased); L2 still 61nF

scr212 shows impulse duration  on L2 in yellow
scr213 shows L2 yellow; orange=L3 voltage 1639.7V pp; and green is L3 current  14.76A pp (L3 on inside rim)
scr214 ""                       ""                                       green is L4 current on outside rim (notice phase shift) 6A pp
scr215 ""                       orange=L4 voltage 3533.1 Vpp   " "                         ""
scr216 ""                         ""                                               green= L4 current on inside rim 10A pp (increased!) and in phase

This was at full power of the PSU, 2x 32.2Vdc @ 1.14A
my audio amp picks up a hum when system is running.

impulse at full power is now -2250V so I should tune to 10th lower sub harmonic of L4 at 134kc/s
this will give L1 more time to charge up a magnetic field, resulting in a stronger impulse spike.
I remember the threshold was around -2700 volts in precious tests.

Other options are increasing the L4 coil size, which lowers its resonant frequency. This will demand a slower impulse, which has a lower voltage, I can then tuned to a lower harmonic to get much more powerful impulses. but this will also make a larger demands on the PSU. I prefer fast impulses, the more rapid the change the harder the slap of the flat hand on the water producing longitudinal waves. if the impulse becomes to slow, I would need much more voltage and power to still get longitudinal waves.
much to complicated... will continue with this setup.

What I also dont really like about this setup, is the L1 dimension. it has a large inside hole diameter compared to L2. due to the thick wire I used for L1. but it makes it fast.

I also noticed my current probe is picking up large curretn is mid air around the coils. maybe due to the hall sensor, or the displacement currents?

I tuned down to the 12th sub harmonic of L4 at 112kc/s by making the parallel capacity of L3 24nF
The impulse now is -2700V duration I did not measure, as experience shows it is steady.
Power now is decreased which is a bit strange to me. 1.0A @ 2x 32.2V DC from the PSU
'
here are the measurements, in between I only changed one thing each time.
scr218 shows L3 voltage (orange) and current (green) with L2 in yellow. note how there is a high frequency oscillation on L2.
scr219 shows L4 outside rim amps in green
scr220 L4 inside rim voltage in orange
scr221 L4 inside rim voltage (orange) and current (green)

It looks as if the current of L4 now is less precise in phase with the voltage. maybe because this is not fine tuned to the harmonic of L4.
Voltage of L4 extra coil is lower, as expected, current also is decreased

maybe the lower 12th harmonic at 112 kc/s needs to be more fine tuned, but it looks like the L4 has less current and voltage in phase, representing less power.
I would love to tune into the 13th harmonic at 103 kc/s to get even high impulse voltage. I aim for -3kV
then, I would also need to fine tune for max power on L4.
 
I also wonder, where to take power out. parallel to L3 as I usually do?
parallel to L4 (in series with L3) which never gave good results
or... in series between L3 and L4, if load is big enough, the resistance should be low enough. both L3 and L4 could be recitfied into the load...

still I feel to see what is so special?

I do wonder what it means why L4 current and voltage are in phase, and current and voltage are amplified

so, what shall I try with the extra coil, now voltage and current are in phase and rather high in quantity?

I want to attach a tungsten needle and see if I can direct the stream, onto a plate with a layer of oil. see if I can move the oil. always fascinated me.

and what about radio? Lets modulate the signal by turning it of and on with 1kc/s
my signal generator might be able to.
then see the range with an am radio.

connect a vacuum tube or filament lamp, a bulb with low gas pressure,, and see what kind of discharge this can produce?
probably need high voltage, which means making L3 parallel cap smaller.
best to make some parallel series tuning caps rated for higher voltages.
hmm ceramic caps?

spark L4 to ground. always fun.

use a fluorescent lamp? connect L4 to water?

anyone got more ideas?

page 23....

what I also need to try,
is place L4 on the inside of L3, so in between L2 and L3

it would make sense, as the displacement of yhe L2 impulse would directly interact with L4, while the L3 on the outside is magnetic shielded by L4 from the L2 primary. so the load on L3 is not magnetic coupled to the input power supply.

another idea is to drive L2 at a lower harmonic of L3, while L3 is still at a lower harmonic of L4.

but this all is not preferred by me, as the frequency splitting between L2 and L3 gives the LMD mode.
whereby the energy is much more amplified

I did a setup with a smaller L2 capacity of 31nF
and a bigger L3 capacity of 61nF
I probed the series connected L4, and tuned way above resonance.
The Ripple of the L4 is now clearly visible in orange.
By measuring multiple waves, I can create a smaller error for the sub octave calculation.

scr222 orange shows 6,5 periods having a duration of 4.575us so one period is 704ns and a half period is 352ns
so L4 is 1420kc/s
sub harmonics:
7th=202.97 kc/s
8th=177.60 kc/s
9th=157.86 kc/s
10th=142.08 kc/s
11th=129.16 kc/s
12th=118.40 kc/s

scr223 yellow shows the impulse duration which is now 408ns. So this is at least 56ns to slow for the L4
L1 is still bifilar, So I could speed it up, by making it unifilar, and tune it down by adding parallel caps again. I dont like that method...

lets first tune to the sub harmonics by changing L2 capacity

tuned to the 11th subharmonic with 28.6nF series on L2
haven't looked at the current yet.
But the oscillation on L4 is still visible, it doesn't form a perfect sine.
What worries me, is that the orange L4 goes down in voltage, when the impulse hits.
that should be in reverse, to amplify the sub harmonic, right scotty?
hmm... Maybe reversing L4, flipping it over, then the current can feedback into L3? add up?
hmmm..
I dont know. need to test this.

current in green for
L3 scr226 : 5A pp

and L4 scr225 :750mA pp

Big difference but understandable, as the L3 has a large capacity which caracterisctic impendance is leaning towards the current amplification, while L4 is towards the voltage amplification.

L3 voltage is much lower (no screenshot)

still the phase shift happens

scr227, current (green) 5A pp and voltage(orange) =108V pp of L3 secondary
Note how the current jumps up after the impulse, then levels off until the positive current peak.
This would work better with a smaller cap (faster)
but a smaller cap would also give smaller power.

It also looks wrong for the current, as if it is diminished instead of amplified. that would mean, I need to flip L3 also.
So both L3 and L4 need to be flipped over... hmm.

flipping L3 would change the polarity of the voltage, which takes away the pumping action between L2 and L3 voltage (non opposite)
This setup is cast in epoxy (except L4) so that would mean I need the other coils again.
I could then also tune the L1 impulse properly to the L4 extra coil again, as it is now to slow as bifilar, and to fast as unifilar.

Another mod I want to research, is to look at the body diode of the mosfets, see If a bypass diode mur8100eg is faster, if the threshold is lower, then It could make sense to use external diodes.

Power out, I want to use a single diode for rectification into DC.

I need to process this first. maybe do some lower octave. but than the impulse voltage is low again. I now have
0.54A 2x32.3V DC input power. at 129.1 kc/s
giving a -2250V impulse. so I would prefer to go lower.

Maybe my other (older) mosfet switch is a bit faster.

I have a long wave radio receiver which tuned down to 153kc/s
so I turned on my stem, and tuned it to 153kc/s by making the L2 series cap smaller. I kept L3 parallel tuning cap at 61nf (large)
result was only a relative small voltage signal of a few hundred volts.
The radio picked up the signal, and even produced a tone.
which is unexpected, as I didn't modulate it.
I walked around the house, and noticed the signal disappeared within 10meters distance. so no problems there.

Now I will retune and make L2 very big, and L3 much smaller, resulting in a much higher voltage (I'll limit L3 to 1800V else the caps will suffer, L4 will be around 4kv pp)
