who did you speak with or even better what did you speak about?

This is your "ideas" thread.  Bouncing ideas back-n-forth with you is helping me put all these little pieces together that I exposed myself to over the years.  Or, maybe the Boys Topside are injecting my brain with things and I keep stumbling across them wondering where I got that goofy idea.

hehe yes. nice one.

good to share. inspiring.

I would love to do a time test.
when the distanced bifilar coil is finished,
I would like to bring it into resonance with some high voltage pulses.

then I would like to have 2 identical digital watches.

one would be placed inside the center of the coil, one would be placed far away.

then after a week of running this coil at its resonant frequency, I would like to compare the time on both watches.

Or maybe a simple youtube live stream. showing the coil with the clock.

would it drift?

good book says dollard:
https://archive.org/details/electricitymatte00thomiala
jj thompson, electricity and matter

from 3:02:10  a good explanation of the bifilar coil.
Dollard states, at the resonant frequency, it grounds into counter space via its capacitance. if its only connected on one side.

he calls it a monopolar transmitter, and because its grounded via the capacitance into counterspace, you can transmit into ground... this explains why I see a signal on the ground connection

in this video he also shows the longitudinal wave as a wave in time, where the dielectric and magnetic field lines, line up in the same direction, in counter space. Very good info, if your eyes and ear, heart and brain are open to it.

if a bifilar phi hole coil produces a ring vortex around it, then a distanced bifilar coil phi hole coil (2 parallel pancake windings series connected with a dielectric in between)
should produce 2 vortex rings one around each pancake winding.

If we only pulse one of the windings, and we would measure the output with another parallel coil on the other winding,

what would it show?

will the one side jump over to the other side because it is series connected? and will it then be measurable?

or would we need to pulse the other winding to make the connection complete? in other words, one of the 2 windings, the one that isnt  near the parallel pulsed coil, is pulsed as a single coil, but still being part of the bifilar coil.

that way producing the combined field of dielectric and magnetic.

pfff.... need to finish this side by side coil soon... and start working with these concepts

I would think that when I ground my dc powersupply signal to earth, to make it more stable, i would have to connect it to the negative side.

but no... I've got 2 power supplies that need to connect the positive terminal to ground.
to work properly.

I think the power isnt 0 and 12v
but its -12v and zero.
its still 12V...
but why is it referenced to ground via the positive side? and not the negative?

isnt that strange?
 :hide:

depending on how we connect a bifilar coil,
we can make it bucking (creating 2 opposed magnetic fields).

to buck, we reverse one winding, so the windings are parallel. this reversing is simply done by switching the connections around of one of the windings.

the windings are series connected. we just reverse the connection of one winding.
a relais could do the trick.

now in one position we buck the coils. put power into the coil, and the fields will oppose. this stresses the eather.as if it is compressed.

then we switch the winding with the relais reversing its connections. Now it becomes a tesla bifilar. the eather now in a flash relaxes, decompresses into the bifilar tesla coil.

I thought of this before, but in reverse. thinking that the bucking might produce an energy output. this still also might be true.

the energy can be fed into capacitors by use of fast diodes(that act as valves)

edition:
as the ether is much fasyer than a switch, this wouldn't never work.
but... we could use separate coils for bucking and collecting. the bucking coils b emf would then be collected by the bifilar coils. a stack of several alternating coils might do the trick

woke up with a thought.

movement of the bloch wall.

in a torroid when it is partly wound there is a bloch wall. we can move this around.
this creates an oscillation.

its the movement of the bloch wall that generates movement of energy.

the inter action of two coils makes the bloch wall move

if properly moved it circulates the energy like a pump round and round.

the blockwall is equal to the dielectric field which concentrates between the windings of a bifilar coil.

opppsition or attraction creates a new bloch wall. alternating fields of 2 coils will shift the bloch wall inbetweeen them.
so if you place a third coil there in the middle, the bloch wall shifts through it.
generating energy movement via the shifting dielectric field

opposing fields create the strongest dielectric shift.

the  coils of a joulethief are normally wound (not counter wise)
but due to the way its connected its in bucking mode.

the current comes in from the middle of the coil and moves parallel to bothe ends, where at one end a resistor leads to the base and the other end the collector is.

these currents produce opposing fields.
when the base current opens the transistor the collector current becomes suddenly dominant as it can flow to the emittor ground.

this current creates a opposing current in the base winding. the base current stops flowing the transistor blocks. the fields produce a back emf; and then it starts all over again.

So the oscilation kills itself over and over again. could we alter this circuit so this leads to a circulation? trigger it different?

I start to think Nelson Rocha's blue distanced coils, are 2 bifilar coils.

both are put into resonance. but in opposite phases. this might induce a dielectric field inbetween them inside the white dielectric.(where a outputcoil coil collect it).

the out of phase resonance can be created by a single pulse that is fed to the 2 outside coils. one coil is reversed connected.

i need to check the inductance of two bifilar coils in series. it seems its acting funny. depending on how they are connected

checks out right. when 2 coils are stacked series connected via both outside rims or both inside rims, the inductance drops (opposing magnetic fields)

just watched a good video on reactance impedance admittance conductance and var.

All these terms have math based on sinusoidal phase relationships between the dielectric and magnetic fields.

BUT
what about impulse currents?
Tesla used these. I believe thats what he did with the magnetically quenched sparkgaps.
sudden spikes of energy. the same can be seen by the discharge of a capacitor dielectric field (back mmf by shortcut) or of a inductors magnetic field (back emf by opening the circuit).

Eric Dollard has understood this (from reading Steinmetz I think) and he talks about infinite "...." (power? i forgot)

A bifilar coil can produce a (resonant) sinewave of large voltage, by pulsing a nearby coil with these impulse currents.

now what is really happening here? the sinus can be explained via the formulas,
but these impulse currents are not. (as far as i know). thats why b emf and b mmf are interesting and need to be better understood.

how the hell can two in phase b emf impulse currents( from a toroid into a bucking coil grounded in the center), fed into a bifilar coil (so a double plus, not a plus and minus).
produce a resonant voltage rise?

both b emf pulses at the ends of the bucking coil show up as positive.
but appearently they are differnt.
Is this due to the reversed windings?
Is this a spin factor we do not yet understand?

I must say, this is amazing and abnormal.

we can measure the inductance of a bifilar tesla coil. but what about its capacitance?

we know the resonant frequency.
and if it is true (i dont know) what tesla there is only the wire resistance left, the capacitive(negative var) and inductive (positive var) reactance have to be equal so they cancel each other out. leaving the wire resistance as impedance (in phase of the dielectric and magnetic fields) no lag or leed.

being in phase also explains the voltage rise (sum of both fields energies).

1/2pi*f*C=2pi*f*L  gives C as 1/4pi*f*f*L
f is res frequency
L is inductance
C is capacitance

correct?
if L = 0.6mH and f=600khz
than C is 0.000442097 F
is 4421uF
(need to recheck this)

4421uF is a lot of capacitance for a bifilar pancake coil.
and... how much capacitance would then be need to lower the resonant frequency by an octave (halve it).

it doesnt check out. I added 7nF in parallel and the resonant frequency dropped much lower

I still believe the best way to put a bifilar pancake coil into resonance is by using the high voltage b emf pulses.

they need very little energy to create. just a simple coil that is being pulsed.

but there are some problems to overcome.
to get proper pulses of bemf we need to stay well below the resonant frequency of the pulses coil that creates the back emf. (or canwe kill the ringing with diodes, and still use the b emf?)

another challenge is to get the bemf into a bifilar coil. to get the proper power transfer, the impedance should match. (can a capacitor fix this?)

then there is the challenge of getting the resonant frequency of the bifilar down. I know this can be done by adding a capacitor in parallel, but if the frequency is to low, the voltage rise also becomes low. (the capacitance needs to be between the windings, maybe add a good dielectric).

the bEmf pulses are best around 50 to 100 khz. depending on the coil used.

so on one side we want a ringing bifilar coil, but on the other side we want not ringing b emf pulses. and in the end. it should match in frequency.

1 high voltage b emf
2 high frequency b emf
3 low frequency resonant bifilar coil
4 impedance matching so the b emf gets transferred to the resonant coil.

in regular electronics we use ac (transverse wave traveling) electric energy. this can easily pass through a capacitor.

these tranverse waves are like traveling water waves. the wave travels, but the water stands still, only moves up and down.

so the capacitor interacts with the ac wave but the water stands still.

But When using a resonant standing wave the capacitor can become hot.

If we again look at water,  with a standing wave, the water can be standing still, like in a basin. but... there is another standing wave where the wate streams past a rock.

In the last example the water ia streaming fast. In that situation using a capacitor will heat it up, because current is really streaming.

so we've got 2 different kinds of standing waves. one where the water only moves up and down ( basin) and one where the water is actually streaming (current with a rock).

so. bottom line:
water is like the ether, and can stream. this is a real current, differnt then what we use from the ac wall socket.

how to tune a bifilar pancake coil?

normally I add a capacitor in parallel with the coil to tune down the resonant frequency.

but Since 2 of my capacitors have melted away i wonder if there are differnt ways...

what happens when we add inductance?
what happens when we add a capacitor in series with the coil?

and what happens when we add two equal capacitors in series and parallel?

what if we use 2 capcitors, one for each winding of the bifilar?

what is we add a capacitor in series in between the windings?

if we want to tranfer energy stored in a capacitor into another capacitor, we encounter losses.

I said before that is is because the back mmf from a cap needs a coil to transfer energy into a b emf that can feed a capacitor.

the reverse is also true.
to tranfer energy from a coil into another coil we need a capacitor.
the b emf from one coil is stored in a capacitor that can produce a b mmf to feed the other coil.

So to use b emf from a coil to get another coil into resonance, we need a capacitor to tranfer the energy correctly.

dielectric b mmf (from a capacitor discharge) into a coil produces a magnetic field. the magnetic field than produces a b emf that charges the capacitor.

diodes restrict the flow of energy. from capacitor discharge via diode into inductor
via diode into capacitor

switches(also diodes) are needed for shortcutting the capacitor into the coil and opening the coil to charge the capacitor

a bifilar pancake coil has 2 strong fields.
one magnetic field
one dielectric field.

at the resonant frequency of the a bifilar pancake coil we see a large voltage rise.

is it because the dielectric and magnetic fields are exchanging energy, back and forth? is the magnetic field max when the dielectric is zero?
 would that be a parallel resonance with max impedance?

tesla in his patent 512340 states only the wire resistance is left.

so this would be a series resonant circuit, with minimum impedance at resonance.

the magnetic field normally shows up as static, meaning a compass shows north at one end and south at the other end. but that doesnt mean its static. I use positive pulses. not negative.
so it still also can be alternating back and forth.

What is the capacitance of the dielectric field at resonant frequency?
if I add a capacitor in parallel the res freq drops. can i do a calculation where i get the capacitance of the coils dielectric field of the coil it self, from measuring the changed frequency by adding a capacitor in series?

the voltage rise also changes when I add capacitance.
I never worked with kirchofs voltage law, but to formulate this correctly i might have to do it by... realising the 2 fields are one. not series not parallel. maybe try the formulas for both, at the same time.

pfff complex... but not impossible. I used to be very good at math. but i will have to practice.

It would be nice to be able to calculate the dielectric capacitance at resonant frequency.

Why?
because I want to add a capacitor that is equal in size, to the capacitance of the coil.
if that capacitor can be in phase with the dielectric field of the coil, and we pulse the capacitor(at res freq), the energy going back and forth from dielectric to magnetic, is double the input. because the dielectric from the coil adds up the dielectric enerfy from the cap if they are in phase.

when adding capacitance to lower the resonant frequency, if seen the voltage rise becoming bigger, to a certain point, and then becoming lower.

this support the previous post.
when I add the right capacitance, the coltage rise should be maxed out.

since I now have 22 caps in series, I can look for this frequency more easily, by shortcutting caps and looking for the maximum resonant voltage rise (no calculations needed).
I the capacitance becomes less instead of more, i simply add more capacitance
