Stebra;

My projected figure of 2500 watts is just IF (a big if)I can get 20kv out of L2.
Power = amps X volts, right?
If you agree then; My half lit 250 ma bulb should be drawing 125ma, right?
IF I can generate 20kv across L2 then: power = .125 X 20000 which is 2500 watts. So where don't you agree?
Yes, it's still a theory but if done right there should be no problem in getting that 20kv.
Once that happens then the next problem will be getting all that hi voltage-low amperage power converted down to a usable level.
But you won't see it with your parallel resonant circuit in series with the S.G.
That NST 60kc output is still confusing you. That frequency simply means that the gap is sparking at 60000 times per second. The L1 circuit just picks the right frequency out of the bunch being generated by the S.G.
Now a parallel circuit builds up amperage while a series circuit builds up voltage (what we want).
This voltage is ONLY limited by the circuit resistance which is mainly the coil winding. Hence the reason for a small coil with large wire (large Q factor).
No you can't just put an anolog meter across a resonant circuit. You will detune it and get a drastic lowering of the voltage. We are dealing here with RF voltages. I also found that resonance has to be set while L1/L2 are coupled together as there is much interaction between them frequency wise.
Yes, there is tiny current in these circuits, but its the total POWER that counts. The larger current will come after stepping down the voltage with an RF xformer.
I'll be trying out some of my ideas once I get my 1500 pf cap and connect in series with my 10 turn 3.6uh coil. Freq. should be about 2.1 mc.
If you'd like a little inspiration, go to google and look up "Henry Moray". He is the reason I'm here.

kapanadze technology

I was thinking about kapanadze technology and how his mysterious machines might have worked.

From the GEO video, the device seems to possess a spark-gap.
I have initially thouth that this spark-gap is the primary's circuit interrupter. Probably i was wrong. Several people have pointed out also.

This peculiar, quiet spark-gap, is actually more like a arc-gap. No spliiting sound is heard as when a capacitor decharges in the spark-gap. So how is running?

Simply, just my Kacher, solid state. The transistors are for driving the oscillator rather than stepping up the voltage for a capacitor. My above argument is solid if we think that in the youtube video of Kapanadze device (3rd party testing 100Kw device), it is seen that the coils arc to another coils or other devices.

So, any idea about the spark-harvest?

Hi Elcheapo,
I congratulate you on your perserverance !
I thought only people like Edison with huge financial resources could do 10,000 cateloged experiments to get a practical incandescant light bulb !
Some said he was successful because he eventually ran out of failures!
We are not in that enviable position however.
Yes I agree,watts = volts x amps.
Fluo type lamps light up on just a "smell" of current, as long as high enough voltage is available.
Filament type lamps - if can be used, show real wattage in action.
I look forward to your results when you have made up a suitable step-down transformer.
Henry Moray certainly seems to have "done it", and we are all again still trying to guess just what he used.
Perhaps my calculations are wrong but, 1 Nan = 1,000 pic.
10 Nan in series = 100 pic.
11 Nan in series = aprox. 90 pic.
I agree that it's the total power that counts.
The primary and the secondary of a step-down transformer will of course also affect the combined resonance of L2 and will then require retuning all over again.
Not an easy road to plow !
Probably the final load placed on the secondary of the step-down transformer will ALSO affect resonance !

The 100 kw video also made me conclude that there has got to be a big coil inside of that green box in the outdoor demo and the spark gap is just a mini-version of what you see arcing in the turkish presentation.
It seems to be more running like a streamer than a typical spark gap.
Reasons could be many, corona production and so forth.

Hi Stebra;

Yes sometimes perseverance pays off. And it's the only way to satisfy one's mind about theories.
But even if things don't work out, it's still a good learning experience.
Smith's write-ups are so full of errors that I just don't trust him.
But if guys like Tesla & Moray can do it with their antique tools & components, surely we can also.
I have a large variable cap from a linear ham amplifier with wide plate spacing, so I'll be using that to tune L2.
Yah I done the recalc.on your 90pf cap and you were right. I went to edit my post to delete that part, but I guess you had already read it.
All those tuning problems you mentioned are just another hurdle down the road. We just have to deal with them one at a time.

[baroutologos]

@ Xenomorph,

Yes. It is a type of "streamer" or "spark" harvester. It silent as a streamer is and not loud as a spark gap. In the turkish presentation, perhaps he used a coil as a resonator (what else?) and he collected the "voltage overflow" or resonance's peak voltage.

Something like that has been suggested by Tores Peres in the Rotoverter group, but to in a totally different context.

In any case and on the ground of the above conclusions, The question is.. Does the streamer has power??? Under what circumstances can be converted to useable?

Yesterday
..............

I received yesterday my automobile NST - Long glow input 12-15Vdc @ 5amps max output 9,5 KV @ 30mA.

Naturally, I put it to some tests, as spark distance, charging my ready made cap bank etc. One striking observation i made is the arc it enstablishes when it shorts via an arc-gap (no spark-gap). Its streamer is quite thin!

I have not any previous experience with streamers and amperage. really, how much amperage have the streamers anyway? It must be noted that this NST is electronic and its behaviour is weird.

But i have tested with an almost full load (3.8 amps input) charging the 26nF capbank and discharging via an magnetically quenched spark-gap. The NST was in series with an 50mA incadescence bulb. bulb's brightness was noted. Afterwards, the bulb was connected via a DMM to a battery and 1K potensiometer. Same rightness achieved at 30mA more or less.
...

My surpsise was that a feeble streamer, that of NST has so much power. I have seen my solid state Tesla coil. Its streamers are considerably LARGER and more energetic. Do they have more power?

Today
...........
I fired my solid state Tesla coil or "Kacher" and having another, same specs air core coil was placed near it. Second's coil end was connected via a larger bulb (100mA) to ground. I put a larger lamp cause i know that kacher's streamers have considerable amperage or the effect that amperage creates.

The free end of the receiver coil i brought it close to the toload of the kacher just to draw a streamer strong enough, but not to kill the resonance effect.
yes, the streamer, happily will travel via the second coil (11mH, 20+ohms) to the ground and bring the lamp to above its nominal incadescence of 100mA. (burned that lamp and replaced with 200mA)

Various things were tried, as to pass the current via the quenched spark-gap at the bottom of the passive coil and still having the bulb on. Etc. All worked.

I am puzzled. IS there any chance that a simple and plain TC to have enormous power on it???

I am planning to have a bridge 100nS, 10Kv, 1amp at the base of the passive coil and charge some caps and discharge them via an spark-gap. We see...

nice to see your experiment

It reminds me of an experiment a few years back:
YouTube - Aromaz 026 - Final Lab Note on Sparks, Corona and Water

Using the spark gap in the ground path did increase the light intensity of the CFLs. Due to the high frequency of the oscillator circuit the sparks have a too high frequency to sound abrupt i believe.

Here you can see the lights changing : YouTube - Aromaz 020x - Missing part of No 020


I think the spark gap introduces many harmonics to the oscillation and that acts like an exciter.

I said it in the plasma globe thread that it certainly does. I bet you could light up an incandescent bulb, too.

[baroutologos]

I have study the effect Xenomorph. There is not anything magical with ground.
Its just that ground will provide an enormous one-terminal capacity. (the other terminal is the Tesla coil's topload or whatever)

In using the ground configuration (this mode) you just create the setup for maximum amperage to flow in your system.

I observe it with my Dr Stiffler's SEC 15-3. At first the SEC was very erratic and cumbersome. But if you connect a ground to the possitive end of the battery, problems are solved and stability in that setup is achieved.

Bottomline, ground provides capacitance.

[baroutologos]

Resonance Experiments

I start conducting resonance experiments, based on Don Smith Concepts.

Using my Kacher, a 555 fully adjustable pulser and a drum coil of 380uH in parallel 125nf, 24nf, 2.2nf and 1.1nf my first solid state experiments observations are the following.

The larger the capacitance for given inductunce the poorer the resonance. e.g. for the 125nf caps, estimated resonant rise was not over 80volts. As the cap was gradually replaced by smaller ones, resonance effect become more and more strong.

At the 1.1nf cap, i managed to achieved sparking of 0.25mm measured with an analysing sparkgap.

At the moment cannot comprehend how Don Smith pulses his 2-3uh 200nF coil to kilovolt range. Just unthinkable for now.

ground / amperage / magic

Hi baroutologos and all,
thanks for the info about your investigations.

....There is not anything magical with ground.

....ground will provide an enormous one-terminal capacity. (the other terminal is the Tesla coil's topload or whatever)

In using the ground configuration (this mode) you just create the setup for maximum amperage to flow in your system.

According to my understanding the second quote is an explanation of the magic.
Does an explanation take the magic away?
However, I think the effect of maximizing amperage is important.

I think Don Smith used it by filling his really large cap bank with this current/amperes which he got (I would say "for free") while connecting to ground.
This is step1.

Then he dumped the high amount of charge through the primary of a transformer (= rapid discharge of the caps)
This is step2.

He repeats step1 and 2 (using an oscillator circuit) in rapid succession or sixty times per second to be compatible with our grid system.

He gets a lot of energy on the secondary side (output side) of the transformer, because the Voltage induced in the secondary of a transformer is a direct result of delta I per delta t ....
where delta I is the dumped amount of charges in the primary winding (bigger caps better results)
and delta t is the timespan in which this discharge happens (the quicker the better).

It is better to use the "free charges from ground" in this way (i.e. store them in caps which are then rapidly discharged through a transformer's primary), than to directly power a load without the use of caps and transformer.
These two possibilities are not equal.

On page 34 of his document Don Smith writes:

Number 12 should be a bank of capacitors. Will have to experiment for correct number. Will be a function of the coulombs (Volt-Amperes) required.

Yes I think it will be impossible to buy high voltage caps of the required size/capacitance. Can one build them at home with copper and/or aluminum sheets? I don't know.

[Xenomorph]

I think Don Smith used it by filling his really large cap bank with this current/amperes which he got (I would say "for free") while connecting to ground.

The basis of your (and many other people`s) argument is to just
assume that there will be suddenly a big current without investigating where
this big current is supposed to come from and under what conditions this will happen. If someone finds a conclusive
answer to this (other than quoting D. Smiths literature, i am fully aware of how HE describes this to happen), then he is a step closer to going through all the steps you portray regarding the output transformation.
No-one has been able to experimentally confirm these big currents in the L2-circuit...
If it was simply the process of establishing a ground connection, then every center-tapped transformer would exhibit that
current gain.

@baroutologos:
Nice that you do some experiments about this.
Your circuit diagram reveals that the voltage you pulse your L1 with is 25 Volt ?
Smith uses high voltage NSTs in the range of 1kV to 9kV to feed the oscillation.
But maybe i am not getting your point, what you expected to demonstrate with your set-up.

[boguslaw]

Why is there a capacitor in L2 ?

[marxist]

with my own eyes

Hi Xenomorph and all,

I am trying to investigate this and I think I have seen the effect, even if only on a small scale.
I am using a "slayer007 exciter circuit" and did an experiment similar to jonnydavro's shown in the second half of his video YouTube - slayer sec experiments

I then grounded one side of the so called AV-plug (= half a full wave bridge rectifier). I described it here:

.....
If you ground one side of the AV-plug, lets say the cathode side, and you again measure the voltage between the two branches of the AV-plug, I bet you will measure a higher value than without the grounding.
I tried it and It would be great if you could confirm that.

PS and if you measure the current between the points in question across a resistor, you will also measure a stronger current when one branch is grounded. Wonder if you and the other guys can verify that effect.
