The bifilar pancake coil at its resonant frequency

[Magluvin]

Hi @Tinman,  I know that overunity people are all liberals by their very nature - but as a moderator you should move all off-topic comments into their corresponding threads - not to feed them with their discussion in their original thread. The question of current after interruption of coil is theoretical question of CLASSICAL physics. The overunity forums are losing their original drive and they get flooded with ignorant pathoskeptics - today most of progress actually comes from private researchers and the classical overunity forums are just watching this development in silent surprise. This is because the free hoarded community is maybe creative and inventive, but it remains undisciplined and lazy enough for implementation of its own ideas. What I'm missing here is streamlined brainstorming of experts leading to proposal and testing of particular circuits. The clueless senior twaddling is indeed mentally comfortable - but it leads nowhere.

If you want to achieve overunity, you should do many things in opposite way, than the common well behaving electricians are doing. The energy dissipating devices use transverse EM wave (light) - so you should use the longitudinal ones. Good boys electricians are using layered coils with serial windings - so you should use bifilar coils with alternating current in winding. Good electricians use planar capacitors with plates of equal area - so you have to use spherical capacitors with non-equal plates. Good boys electricians use DC current or AC current in harmonic waves - so you should use pulses. And so on...

The way I understand the build up delay of self induction is that the input current through each turn induces the other turns with their 'outward expanding' magnetic fields, of which that self induction 'tries' to push against the input currents, giving us our delay to max current.  Now if the 'outward' expanding fields try to cause currents reverse of the inputs, then it is very logical that when the input is disconnected, that the magnetic field that was generated will now collapse 'inward' and will generate currents in the coil in the same direction as was the input current. If the field were expanding out, current will be in one direction, and that field collapsing inward will generate currents in the other direction.

Using the sim with the circuit that comes up as default, change the resistor values to very small and add a diode across the switch.  The cap can be made very small so that in real world circuit there isnt the big inrush to the cap from the input, which seems to be quite a bit of measured power in that instant.  Now when you turn on the switch, the cap charges, naturally due to the connections of the circuit, and the inductor starts to build its field. When you release the switch, the field collapses and charges the cap till the field is completely diminished, then the cap reverses the current through the coil and will send back most all of the input spent, back to the input.

You can slow down the sim to watch.  Like say if we did the same to a pulse motor coil, this simple quick reversal with the cap helps some in getting the input to the coil back to the dc source without complicating things to do so. Its like letting the lc go for 1 cycle, then back into the input.

@Tinman,

Current reverses direction and travels in the same direction at the same time like the 60 Hz A.C. current in our overhead transmission lines; Like boarding a bus and moving toward the rear while the bus is accelerating forward. It may appear to a stationary observer that the bus passenger is standing still.

I dont know if that bus analogy works unless the power towers and high tension lines were on the move.

Are you saying that there is a delay in a cap discharge, due to the nature of the cap itself, or due to the impedance of the discharging device?

If we were to make a home made cap with foil, wax paper and say a straight copper wire to make end connections for each plate, which would be the better method of winding it? With the plate connection wires both starting at the beginning of the rolling, or 1 wire for the bottom plate at the beginning and the top plate wire at the end of the roll, and say its a 100 turns, would there be a difference in how the cap works in these 2 cases? Would one have more induction issues than the other?

@Mags,


I don't want to compound the problem too much. I explained that my intention was to imply that the curves are non chiral and symmetrical. I also explained that there's an RC formula for the time that involves a resistor. Now, I don't want to be accused of trying to weasel out of a pickle, but if the capacitor is discharged through a high value resistor, wouldn't it take some additional time for the resistor to begin to pass the current? It would depend on which side of the resistor you measured the discharge from right?

Look at the graph he posted, in "support" of that claim.

Where, on that graph, is the maximum rate of charge? Where, on that graph, is the maximum rate of discharge?

@Tinselkoala,


The maximum discharge is between 100% and 63% of the charge, the maximum charge level is between 0% and 37%, then it begins too slow down to 63% where the time frame elongates again to match the 37% level of the discharge. Everyone knows it takes longer to charge a capacitor after it's 63% full then at the beginning and conversely, it takes longer to discharge the remaining 37% as it empties out. We have an inverse but symmetrical curve. Got it?

@Tinselkola,


You stated that a vertical discharge curve was impossible. What about Tesla's "Spark Gap Generator" discharge?
