There is. But you must first start thinking in terms of intensity rather than quantity.

Many like Tesla and Victor Schauberger claimed we should be more concerned with the "Qualities" of a given form of energy rather than the quantity.

What qualities does one form have that another does not and how do these relate to one another.

For example, my hair pin circuit could light a small bulb under water ten feet away using one very small 30ga wire conductor. The qualities of the energy are not like low voltage AC/DC or HV because I could hold the wire and not get a shock. The form of energy discharged from a hair pin circuit has many very specific qualities.

The common thread among the greatest inventors was that they were more concerned with the qualities something possessed. That is, a distinctive attribute or characteristic possessed by something. How something measured against other things of a similar kind or how they differed. These inventors did many experiments looking for new phenomena with different qualities than we know. They would pay great attention to all the little details most would ignore always trying to refine and expand upon the process. Thus that little quirk which most ignored could become a great force within the devices they built.

The devil is always in the details...

So, I've made a new setup a some measurements. I use solenoid coils. The "kicking" coil, that creates the large and narrow back-EMF spikes (up to 5-600V and 60ns wide!), must have a relative high resonance frequency I think. The best solution fot that is a short coil with large diamater, large cross section (-> low resistance) and some space bw. the turns (-> low capacitance).

The resonant coil is made of isolated litz wire to reduce resistance at high frequency (skin-effect). The resonant frequency is about 29.2 kHz with 220nF capacitor.

The value of the resonant capacitor determines how much energy can be maximal stored at a certain voltage level (E=1/2*C*U²). If this energy level is reached (or at least about 90% of it), the energy stored in this cap can be extracted to the consumer. As you see in the picture, the first about 10 period has a relative steep slope, after that will be flatten so we will not have any benefit farther.

The method could be to build an extractor circuit. If the capacitor voltage level achieves a definied value, a switch with hysteresis (perhaps a comparator with MOSFET, earlier used a spark gap) delivers the charges to another puffer capacitor. As this exchange completed (a definied minimum voltage attained), the switch closes and the process starts again and again.

I've made a rough measurement (see table). The values are taken from the stabilized oscillation phase, the input power (voltage, current) read from the PSU displays. Energy calculated with the time of the first 10 period (E=U*I*t). Capacitor energy calculated as wrote above. The efficiency is so about 70-80%. Another, more accurate measuremenst are needed...

Great work fejleszto!

After taking some distance from the work, I gained insights:
since L1 isn't resonant but L3 and L2 are, it makes sense to loose couple L1.
I measured at what distance this worked best and came to 29mm, which is half of my center hole diameter (pancake bifilar).

Since we need both forms of induction (dielectric and magnetic) it makes sense to have 2 primary coils, for a single secondary.
That is why I am now working with L3 (secondary) in the middle of L2 (series resonant, impulsed) and L1 (pulsed, producing impulses).

So, L3 is in the middle, and close coupled to L2.
L3 is loose coupled (29mm) from L1.

In the back of my mind, the idea of tesla's "extra coil" still itches.
Do we need another 4th coil to step up the secondary (L3)?

Ivo! We must definitely achieve a more efficient system by generating the back-EMF pulse!!!
Your new circuit works very good, I built it too. BUT! It wastes a lot of energy unnecessarily!

A better solution would be a push-pull system, where the coil is between the PSU and the MOSfet, and NOT bw. MOSfet and GND! A relative large cap (10.000uF or similar) schould be near the coil on the PSU side. Following with a HF filter coil, blocking dionde and a current limiting resistor.

So (one side presented): PSU -> R=10Ohm -> HV-Diode -> L=10uH -> C=10.000uF (low-ESR, parallel) -> back-EMF coil -> MOSfet -> GND.

Benefits:
- The HV back-EMF pulse generated by the coil will not be fully wasted, but captured and stored in the large puffer capacitor.
- Hopefully, the duty cycle can be drastically reduced (open time of the MOSfet). We must only maintain a stable puffer cap voltage, not feeding the ground in the about 50% of the time.

Please think about!   

(the picture is only for illustration, don't contains all of the components I've mentioned and designed only for one power supply line)

Interresting idea's, please proceed and share the results.

For me the impulse is not wasted, the resonant energy is even more amplified when the impulse is not fully absorbed in the series resonant capacitor!

I am researching this effect of the impulses in the current of the coils. So I do not want to store them in a capacitor.

 the impulse seems to induce the longitudinal component of the series resonant primary coil

What I intend to do next, is switch mosfets in series by using the isolated gate driver. this will give the ability to create much higher voltage impulses

a single radiant half bridge PCB can also be used to switch 2 mosfets in series, simultaneously. I made a new video that shows this idea
https://youtu.be/w9I88HYY_Z4

and intend to use 4x 1700V mosfets (2x 2 in series) to create 3400V impulses (2x 4x 1000V blocking diodes).

For me the magic is in the effect of the impulse on the impedance of the resonant system.

Ivo! Do you know the patent US 2004/0057255 (2004-03-25)? There are a lot of useful informations inside! Please see the text [0057], that is exactly what I was talking about! This patent mentions nothing about resonances, and uses a permanent magnet and iron core. Would be intresting to figure it out how to eliminate them (if possible).

Another intresting patent is the WO 2013/114285 (2013-01-30). Unfortunatelly, it does not cover up any important details.

The circuit from Tesla (Electrical Experimenter 1919-07 or US 609245 from 1898-08-16) what you mentioned in your last video is very fascinating, BUT! He wrote: "The essential parts of such an oscillator are: a condenser, a self-induction coil for charging the same to a high potential, a circuit controller, and a transformer which is energized by the oscillatory discharges of the condenser. There are at least three, but usually four, five or six, circuits in tune and the regulation is effected in several ways, most frequently merely by means of an adjusting screw. Under favorable conditions an efficiency as high as 85% is attainable, that is to say, that percentage of the energy supplied can be recovered in the secondary of the transformer." So, about 0.85 COP is not our goal (I've calculated 70-80% too by my experiments)! Anyway, it is strange that the coil "B" is connected to the positive(+) power supply without blocking diode, not like by your circuit parallel with "A'". But I need to read carefully the whole patent to make conclusions.

No I do not know that patent.

Yes in that configuration of Tesla I also reached about 85 % efficiency. But that doesn't mean we can learn from it, and advance it!
My idea still is to use a dual primary coil, and with this circuit it can be done.
It really fascinates me he states there are up to 6 circuits in resonant relation!

I made another video, it show the series mosfets switching together, using a basic Radiant power circuit (2019 april),
which is the same as this tesla oscillator.
This makes it possible to create high voltage (3500V) impulses, from coil discharges.

Many think Tesla only used capacitor discharge impulses, by making use of quenched sparkgaps,
but as the article shows, he used coil discharges in his later years of research,
which benefit because
the discharge energy doesn't pass the switch (spark). If the Tesla oscillator coil discharge, was tuned properly,
 it would discharge through the series resonant (low impedance=wire resistance) primary coil,
and would NOT create a spark when the commutator opened the coil circuit, that created the voltage impulse.
Thats why his relays coil kept working so long.

This new video  of me, shows the series mosfets switching:
https://youtu.be/7vfDjN2hkBg

Multiple mosfets could be used, but the bottle neck would probably be the isolated gate driver (which could be a optocoupler with glass fiber)
, and the isolated dc dc converter (which could be a battery).
I tried using 1700V mosfets, but their pinout was wrong.
The c3m1200V mosfets are on order but should be available later this year.

I've found an intresting wiki article: "Resonant inductive coupling", see attached!

"Power transfer: Because the Q can be very high, even when low power is fed into the transmitter coil, a relatively intense field builds up over multiple cycles, which increases the power that can be received at resonance far more power is in the oscillating field than is being fed into the coil, and the receiver coil receives a percentage of that."

How can I understand this statement?

Tank circuits recycle energy!!!!!!!!!

Resonance in a parallel LC circuit: "If the frequency of the applied current is the circuit's natural resonant frequency..., resonance will occur, and a small driving current can excite large amplitude oscillating voltages and currents. In typical tuned circuits in electronic equipment the oscillations are very fast, from thousands to billions of times per second". https://en.wikipedia.org/wiki/LC_circuit

It works.
I made a half bridge circuit, from 2x2 series mosfets. This way the impulse voltage can be made much higher:

I've studied this patent, unfortunatelly not an easy text. The main goal is to produce a very dense magnetic field for scientific pourposes. It can be achieved with approprite dimensioned resonant coils.

Resonance can be presented in two ways:
A) The LC resonance, which means a periodic energy transfer bw. magnetic and dielectric fields, as we already know.     
B) As e.g. Don L. Smith sad too, the wire lenght must be calculated as a minimum of 1/4 wave lenght for a standing wave situation. The reflected waves cause in this case not a random shape (like an ocean surface) but a well definied large maximum at definied positions. This calculation takes the light of speed in account. So e.g. for 50kHz I calculate a wire lenght of 1500m (1.5km!). If I take a 10m wire, the frequency is 7.5 MHz. These are impractical values for a simple application.     

I'm not sure that an electric signal (not the electrons!) travels really with light speed in a real (RLC) conductor. Better say, the signal can travel with about 50-99% c, but the waveform what is created can change because of capacitive and inductive parts much-much slower. But ok, after a small amount of time we have a standing wave with a maximum.   

I must be honest, I can not imagine if I combine this two effect together what will be my benefit. How will be look such a magnetic field?

In some project of Don Smith, he mentioned that the important thing is only the relative wire lenght (1/4) of the primary and secoundary coil.
The reason for that it, it should be no unwanted back and forth signal coupling generated (causing an uncontrolled behavior becaouse of totally different wave shapes in the two coils).

Or what do you think?
