Hi magpwr,
"Grenade" coil in Kapanadze, Akula and others- I think the purpose is to slow down electromagnetic wave propagation.
It is slow wave helical transmission line, coil wound in a curious way.
This is to physically reduce the size of the coil  to accommodate wave of lower frequency.
Tesla secondary and "extra" coils are exactly slow wave structures, to accommodate quarter wave  in kHZ 
area, to minimize radiation of electromagnetic energy.
The aim is to efficiently accumulate energy from primary LC circuit, with minimal radiation into space.
Very interesting subject to explore. I still don't understand the way "grenade" coil works and why that way of coiling.
Kind Regards,
Pix

Hi folks,
It  some thought experiment.
Imagine that at the same time from the same source  we feed step up signal to straight conductor and slow wave structure ( for example loaded transmission line).
If we connect osciloscope at the ends we should see an impulse, due to electromagnetic wave ( potential) propagation time difference.
Am I right?

Am I right?

simplified but not always correct answer:
You will see the same  signal coming with delay as slow wave  comes later,
that may be seen as phase delay.

For easier understanding here is an example.

First path:
Think that  straight line from  New York to to Warsaw ( or from bottom of Tesla coil to its top) is =x in meters.
Second path:
you created  additional path.
It is a coil with diameter  1mm  wire 
winded tight on the tube of diameter 1 meter
and  long from  New York to to Warsaw ( or from bottom of Tesla coil to its top)
=x multiplied by n times of x  in meters.
conclusion:
-signal on that coil will travel many times longer till it reaches its destination.


But you may  also want :
-this coil to resonate....
-convert an input voltage pulse into radiation
-have impedance match to desired 50 Ohm.

however we don't need any longer traveling wave tube we can do it with semiconductors now.

power receiver for extracting power from electric field energy in the earth

The power receiver 10 converts energy in the ELF/ULF waves to useful form, e.g. 60 Hz AC or DC.
The power receiver 10 is essentially a resonance circuit that resonates at the natural resonance frequencies in the earth's electric field.
These resonance frequencies, known as Schumann resonance frequencies, occur at 7.83 Hz, 14.3 Hz, 20.8 Hz, 27.3 Hz, and 33.8 Hz.
A high voltage impulse initiates resonance within the power receiver 10. In the resonant mode, the impedance of the power receiver 10
is reduced to near zero thus inducing ground currents to flow into the power receiver 10 where the ground currents are converted to useful form.

Hi Wesley,
I don't see in Earth Energies Inc. patents how they propose to make resonant transformer in range 0.1-200Hz.
They state to make it resonant in fundamental Schumann resonances 7.83Hz,  14.3 Hz ect. but it might be physically very large.
Big Tesla coils operate in kHZ ranges, and secondaries are at least  few feet tall.
So, the challenge is to construct a coil resonating in very low frequencies. To do it, we need to use "slow wave structure", we need to slow propagation of electromagnetic wave like Tesla secondary or maybe in other, more clever way.
Kapanadze, Akula "grenade" coils might be some sort of solution to slow wave propagation. I don't understand the way they are coiled and a reason behind this shape of "grenade".
Principle of operation of Tesla-like systems, like above mentioned patents from Earth Energies Inc.  is clear, the point is to find a way how we construct resonant winding for frequencies close to Schumann resonances, and have reasonable sizes.


Regards,
Pix

first  step is to understand .. not the patent but mechanism of making  coil small at VLF.
 
 and  only than  you can  think about  slow wave.
Tariel didn't understand anything..  but .. how many people wins in lotto?

Utilizing the Dr James Corum  understanding of phenomena in  question:

Quote
Such coil that normally at Schumann resonance frequencies would be physically large,
it would still be electrically small and therefore realizable, as well as efficient.
Because propagation losses are so low at the primary Schumann resonance frequency
(below 0.25 dB per Mm according to published data),
-signals at that frequency may be transmitted to any point on the earth without significant attenuation.

in practice we are not expecting to build LC circuit  resonating in Schumann frequency resonance in our  VLF coil.
We would like to.. but  we can't..
..that is why Dr Corum  works at 18kHz or any  lower possible frequency representing  harmonic of Schumman F.
 the fancy Tariel Kapanadze coil was set of winds  CW and CCW
 making coil electrically  suitable but physically small.
well..  we may have question that this coil  was not vertically polarized.
that is yet another  story to talk about it.

hi pix,
I am not sure how to to answer any of your queries.But all this while i was dabbling with harmonics 3,6,9.
I am not even sure if  i am correct to say this if we see a rising amplitude waveform can we safety say  "Q" Quality  factor is more than 1".So what does Q factor more than 1 represent if we did involve the "strange winding" in in this scenario.
Loss or no loss,less obvious loss.Or should we even involve Q factor in this case under HV 3rd harmonics manipulation with resistive load(Mains Bulb) and observed no further increase of input current even with short circuit test across bulb?
1000watt halogen bulb load would be next once i have the time.

Understanding Q:
-quality factor,


The Q factor determines the qualitative  behavior of simple damped oscillators
When (Q < 1⁄2) is said to be overdamped. Such a system doesn't oscillate at all

Quote
The condition of Q = 1,
when the power being released by the fusion reactions is equal to the required heating power
,
is referred to as breakeven, or in some sources, scientific breakeven.

Ani wytwarzanie wodoru, ani zbudowanie ogniwa paliwowego z całą elektroniką nie jest problemem, tylko największym problemem przechowywanie wodoru,
z uwagi że wodór ma najmniejszą cząsteczkę z pośród wszystkich gazów to nie może być przechowywany w zwykłym zbiorniku, czyli musi posiadać tzw. "gąbkę wodorową"
aby można było pod dużym ciśnieniem utrzymać wodór w zbiorniku, jak również cała instalacja transportu wodoru do zbiornika musi być odpowiednio wykonana.

Wszystkie te technologie które mogły by być lepsze od ropy naftowej są negowane przez media które są opłacane przez magnatów ropy naftowej.
