When looking at the current we should be able to see the sine wave jump from zero up, at the time of the impulse, this should represent the ideal displacement current. lets look for that also.

scr 76 is with 60nF less on L2
scr77 is with 117nF on L2

its not clearly visible.

I could increase the l2  capacity even further, or reduce it further, although reducing, would demand large capacity on L3 to keep the frequency down.

increasing might be interesting. but I think I rather prefer loading the series parallel L3 L4 and see ho much power is being produced

 should measure inductance of L3 and L4

ideally they would be 1:2
and this way I can adjust the L4 windings untill it fits

capacity also is in play, and should also be double which makes it tricky to get right.

the basis for this, is the equal frequency for series or parallel resonance as tested today with L3.
equal coils would be easiest, but probably won't give amplification.
but a relation of 1:2 (L3:L4) should amplify, as L4 would be lower in frequency then L3.

hmm hej... thats not right. L4 would then have a lower frequency than L3, so when driven at the lowest frequency (L4) L3 would function at a lower harmonic.

But I wanted L4 to function on a lower harmonic, not L3.
hmm

that brings me again to the idea of placing L4 between L2 and L3, making L3 the outside coil im the stack.

my series and parallel resonant test did not show any difference.

But... the high impedance difference between the 2 modes should have shown up in the power supply, right? Or not?

I wonder if this truly is a series and a parallel mode, as only one capacitor is added to the parallel mode, to make it series. I don't see the difference, so... that makes me wonder.

Maybe I should stick to Tesla's design, and ground in the atmosphere using a single plate (ball) to ground in the atmosphere. to achieve series resonance in the extra coil. This would make the extra coil half wave resonant. which could be measured at the series connection of the extra bifilar coil, which shoupd be lower in voltage than its ends. (but still high as it rides on top of the secondary l3 wave).

I am wondering if anyone can follow this. or am I a true pioneer?

ok, I call my secondary L3 coil parallel resonant with c3. but is it? As I ground one side

Should parallel resonance not be u grounded, so both ends of the coil can interact with the cap?

hmm

finally the summer heat has passed and it has rained again. it was so dry, the smaller bushes and plant were dying.

I series connected L4 with the C3 cap 21nF but not series connented it to L3
L3 is outside grounded, inside probed, it shows a clear ringing, which should match the impulse half wave duration.
but as it is now, the L3 is faster than the impulse, so I will make the L1 coil unifilar, by parallelling its 2 windings.
This way it becomes faster, by having less inductance and capacity.
I will then tune it so it matches the L3 frequency
orange =L3 voltage (ringing)
yellow= L2 impulse

Since L3 is the capacitor plate that receives the displacement current from the impulse, it should also be tuned to it.
This is also how tesla worked at his Colorado springs lab. the primary, and secondary were close coupled. while the extra coil was in the center of the secondary

I had the L1 bifilar, but it was to slow, so I parallel connected the 2 windings, into a single winding. it now is much faster then L3.
I can add capacity and tune it.
I would have preferred to have more windings on L1, so next time I will start with a unifilar L1, and reduce its windings, unstill it is perfectly matched to L3. than I wont need a parallel tuning cap over L1, and this should be more efficient.

same setup as previous test, but now tuned to 92.5kc/s as this gave the best ringing on L3 (orange)
L1 (yellow) halfwave =171ns
L3 fullwave= 610ns, so L3 halfwave is 305ns

now I need to add a few pico farads parallel to L1, to prolong the duration of the impulse.

With the same setting as before, I added 9x 68pF in parallel with L1.
this slowed the half wave down to 290pF (yellow)
L3 is still at 620ns fullwave, making the half wave 310ns
So this is a very close match. I will leave it like this. I could add another 68pf but the board is already crowded. and I dont want to make the impulse duration any longer.

the currents from the supply are way up, as the L1 coil now barely has any inductance/impedance. but thats fine.
2.94A(!) @ 2x 21.8V=128W input from the DC supply (so voltage is down, amps are up, I can easily create high voltage impulses this way, as my PSU is 5A 2x32V

So, now L1 impulse (super imposed on L2 series resonant primary) is matched to the free resonating L3 (while being coupled to series resonant L4)

L4 is not series resonant at this point (tuned below resonance) So it could add some extra impedance to L3, making it slower.
but thats fine. I could always make the impulse of L1 faster again, by removing the parallel caps over L1

Still using the same setup same caps, but now series connected L3 and L4, to become series parallel resonant with C3.
Since it is not tuned properly yet, the LMD mode does not appear to produce much power.
So I tuned to the lower TEM mode at 54.23kc/s.
This again demanded huge amounts of power (since L2 and L3 are now in phase)
input was 3.52A 2x 7.2V DC =51W

lamp could become very bright, whit higher power. 42W 230V halogen bulb.
connected to rectified DC caps (2x 10uF in series, center grounded) which was charged, from 2 diodes connected to L3/C3 and ground.

orange shows L3/c3 before being rectified.
L4 extra coil was again grounded through the large 3uF cap.

Tuning was to most light output, which was when the impulse was almost fully absorbed into L2C2 series resonance.

So, now tuning L2 L3 L4 comes in play. I zoomed into the ripple to get a view of the ripples on L3.
since impulse has low voltage, it appears slower 330ns
6 period ripples on L2 were 4.3uS (measurement error, I needed to measure orange ripple)
so L2 ripple is around 1395kc.s

orange ripple on L3 was 1.694us for 2 periods, so half wave =423.5 ns
so ripple on L3 was 1180.6 kc./s

I strongly feel the L3 and L4 coils, need to be resonant harmonics of each other, L4 being at a lower harmonic of L3.
So the coils need to be tuned to fit together.
Better said, L4 needs to be closely matched to L3. so that L4 is a lower harmonic of L3.

I could tune this by making separate setups for both coils, so they are uncoupled.

But since L3 is coupled to L2 and L4
while L4 is only coupled to L3, is would be best, to test without being uncoupled, as everything would detune again.

best would be to let the L3 ring by itself as I have just done, and let L4 ring by itself, and compare the frequencies, then adjust L4 (windings) to match L3 as sub harmonic

L3 fullwave= 610ns (Reply #530)
L4 measured around 1428ns for 2 periods=714ns (reply #512)
so from these it looks like L3 and L4 are closely matched, but I think this measurement is wrong, so I need to redo those tests (whitout the cap on L4 ground).

I still need to check if the L3 current amplification is jumping higher now, from the faster, matched impulse

L3 orange scr99  full wave is 622.4ns 1606.7kc/s
This was tuned to slightly above TEM resonance (to get the impulse on L2)

scr98 shows L3 ringing by itself, while being coupled to series resonant L4 (TEM)

scr96 shows L4 being out of 180 degrees phase with L2
 which is weird, as L3 is in phase with L2 (scr97).

So while they are connected the same way, the phases differ between L3 and L4, why is that (in TEM mode)

scr95 shows L4 resonance (detached from series cap, while coupled to par res L3) which is
1586us 630.517kc/s

scr94 shows L4 (orange) ringing on top of the L3 resonant wave (LMD resonant)
Tuning caps still the same as previous tests
****************
so the coils by themselves ring at:
L4= 630.5kc/s
L3=1606.7kc/s

I wont change L3, so L4 must be tuned to be a subharmonic of L3 1606.7kc/s :
1st   803.34 kc/s
2nd  535.56
L4 is now 630.5 kc/s I can speed it up to 803.34 by removing outside rim windings.

Probably good to place this on video

to clarify: I do this, because both L3 and L4 coils, must become resonant with the same tuning cap C3. If they are not harmonics they will not be able to become resonant.
And I feel that having them 1:1 is not going to give amplification.

I have removed the 4th outside winding from L4 eachtime also checkeing L3 resonance which also slightly become faster

When measuring L3 frequency by itself, I had L4 being series resonant with C3.
I noticed, I could not tune into LMD resonance this way. Probably because L3 was in between the L4 and L2.

So I tuned to TEM resonance. which normally has L3 and L2 in phase.
To my surprise I saw that L4 now was 180 degrees out of phase with L2!
So... I think I do need to flip over L4, to get it in phase with L3.

When tuning TEM the impulse disappears on L2, so the phase flip could not be caused by L3, as it was not ringing (I had the idea that the impulse flipped the polarity of L3, and L3 induced L4 resonance.

So... flip over it is.

I removed 5 windings, which now has tuned L1 to L3 and L3 to L4.

87.6
77.5
76.5
75.2
68.9

385.7 cm total removed from 20 meter 0,75mm2 makes 16m and 14.3 cm for L4

I flipped L4 over so now its counter wound relative to L3 L2 and L1

I hooked up both coils, and tuned to LMD resonance (still using same tuning caps)

It was fairly high this time, at 193.23 kc/s
I used full power of the supply, which gave 1.74A dc annd 2x 23.2V dc=112W

scr113 shows L4 current in green
and scr114 shows L3 current in green
notice that they both are IN phase. which is good

Now tuned them to the sub harmonics

I do not feel the need to measure L4 again (by itself) after being flipped over, it should still have the same frequency, and changes should be minimal

I still wonder, WHY HAS L4 PHASE FLIPPED?
is it because the aether now flows around L3 L4 as a ringtoroid, and it moves from out to in at L3, while it moves from in to out at L4?

L3/L4 tuned with 61nF scr115 and 116
and tuned with 31nF scr 117/118
green current is from L3 (scr115 &117)
 and L4 (scr 116& 118)

current is less in L4 as more inductance prevents current build up, but it should produce more voltage

L3 L4 current are again in phase. still wonder if flipped L4 is the way to go, it seems unnatural

but |I should do a load test again, and play with the tuning.

scr15 shows the current jump on L3 (not visible on L4) from th eimpulse displacement current, when using a large cap (bad tuning)

When loaded by the halogen lamp (rectified into cap), I can only get it to light in the TEM mode. LMD doesn't even show up.
I might need to us several c3 caps, to get the right value/frequency.
L4 was still flipped over.
rectified from L3 L4 series connection

asked for help last night, and this morning got new insight

just before waking up, I was dreaming about the voltage impulse,
The first half of the impulse (quarter wave) is amplifying the current of the L3 secondary.
This can clearly be seen when the parallel tuning capacitor of l3 is made fairly large,
Then the current jumps up. When properly tuned, this jump flows along perfectly with the sine wave of L3.
And then the current is amplified. (see scr115.PNG of post #540)

But...
Thats only the first half of the impulse, the first direction of the displacement current.

The next half of the impulse (second quarter wave) what does that do?
The polarity of the displacement current now changes. as the voltage changes back from max to zero again.

The L3 secondary coil, with its strong magnetic field vortex, now acts as a diode, as the L3 current moves the other way.

So What does this displacement current do? Where does it flow?
Is this creating the inflow, from the earth?
The vacuum that is filled by the earth?
And what is being filled? Not L3.

So if the first half of the impulse interacts with L3, and the second half does not interact with L3 (acting as diode)
Then, Does it interact with L4?

So L4 is interacting with the second quarter of the impulse?
This means L4 should be opposite in current direction!
And it is (was) when L4 is NOT flipped over.
OK! :cool:

But how does this work?
L3 is tuned by C3
But now... L4 is also connected to C3, so... L4 should be tuned?
How does that work?
Is that a case of impedance matching?
How do I tune the L4 to the second half of the impulse?

In the dream, it was said I should use the second half of the impulse to create an external inflow

The voltage impulse induces dual polarity displacement currents.
one out of the conductor, the other into the conductor.

L3 uses one, to amplify its current.

But what about the other direction displacement current. For it to amplify the current, it should be opposite polarity.
I thought that was happening in L4. and yes it does.

But it also happens in L2! the primary.

So what If the action is between L2 and L3 both coil/plates using one half of the impulse, each using one direction of the displacement current.

I have been using large amount of capacity, and tuning above resonance with my primary.
But maybe this is the way of tuning it properly. I definitly should look at the current of the primary again, as I have also seen it jump up. Even more so than the L3 current.

Now if both jump up, that would be Ideal.

but what does that mean is happening to the volume of aether.
a fast in out, that spins up the magnetic vortex of the primary and secondary.

I still wonder how to pump out of the earth. how to ... yep

the inertia of resonant magnetic fields of the primary L2 and secondary L3 coils work as diodes for the displacement currents.

in LMD mode they are out of phase, which reverses their diode blocking action. So each coil only gets amplified in current by one half of the impulse displacement current.

since its a voltage impulse we have dual polarity displacement currents.

coil and and cap are series resonant (how doesn't matter)
so mosfet has huge current, and needs to be low resistance Rds

when coil is max current, the mosfet switch is opened.

the resonant energy want to transform and will but now without the Capacitor, so it will use the much smaller coil capacity.

this makes the voltage jump very high (can kill mosfet) this is a resonant voltage impulse half wave.
of much higher frequency due to lower capacity.

then resonance continues for second half wave, and body diode will conduct the energy back into C.

resulting the Plate P recieves a large Kick from the impulse and the ground responds, with displacement current.

this would be part of a larger circuit with more coils and caps.

a Voltage impulse induces 2 displacement currents of opposite polarity.

So the positive or negative voltage impulse only changes the order of polarity of the displacement currents.

First in then out of the conductor (negative impulse)

or first out then into the conductor. (positive voltage impulse)

I want to try the DC offset again, but this time only on the secondary coil, and positive.
For it to work, I need a capacitor to ground, that is charged to positive DC, from the negative dc impulses.

L4 extra coil, will be directly grounded again, and not connect to L3. acting as a capacitor plate
L4 might even be a single wire capacitor thus without the series connection

So I will use the same circuit as before, adding a capacitor and 2 diodes at the L1, and then instead of guiding the positive DC to L2, I will put it to L3
L3 thus has a capacitor to ground, which even can be a resonant series capacitor maybe.

I have also been thinking about the capacitor that stores the energy of the second half wave after the impulse. That cap also could become resonant with the L2 L1 that are connected in series when the mosfet is turned off.
But this idea is probably useless. none the less... fun to look into.

I want to stick with one impulse per wave of the L2 primary.

But see how L3 L4 responds when they are at higher harmonics.

maybe only the grounded L4 at a higher harmonic.

lot's of ideas

can C3 become resonant?

L1 creates neg impulse.
c1 tunes impulse.

L2 c2 series resonant.

second half wave of L1 charges C3.
I made c3 big, but what if I made it small, could it become resonant with the system?

this would truly be parametric resonance, as C3 and L1 are added to the L2 C2 series resonance. and removed again due to the mosfet

maybe a wild mind fart, but worthy to look into
