How about displacement current ? Isn't that related to the gradient of voltage ? If you look at 6 turns coil as a metal plate from Tesla radiant energy patent and in the same moment as a single plate capacitor (very eak one) then maybe radiant energy sprinkling on it would generate displacement current between Earth capacitor and capacitance of the circuit ?

I think someone should look at that patent - there are various interesting solutions there. For example someone could put a storage capacitor instead of bulbs in series.Then of course a triac or other discharge path is required to get out pulsing DC + a spark gap for protection all across capacitor to the load.
Plain and simple.Having big chain of capacitors of known parameters and measuring time between each discharge could allow also to measure output power though with some difficulty.

Hi all,

I was very excited when Naudin finally published The Circuit
and almost started building... but now I must sadly say that I Smell Fish
(and it's not fresh). Naudin has a reason to draw 5 (five) 150W
bulbs on circuit powered by 800W transformer (5x150=750+50(losses)=800)

Something is very wrong with this circuit. The Russians also
say it has "nothing incommon" with original Kapanadze circuit.
I speak russian so I have done great deal of research in
russian forums. Here are some key points that may move this
from dead spot:

- think of grounds as of making a "earth-capacitor"

- investigate "Ñ...иÑ,рый Ñ,рансÑ,,ормаÑ,ор Зацаринина":

many russians think that it is hidden inside of the tube:
(copper rod - split copper pipe - permalloy or ferrite - tube - outer coils)

- investigate Tesla Hairpin Circuit

http://www.youtube.com/watch?v=UsS0BeVeIwM
this is simplest way to produce pure radiant and
also lights halogens very nicely...

I myself think that the "real thing" might be
something like Hairpin, at least one of the
capacitors is capacitor made by earth-connections.
Spark gap somehow fires to the ground, not to the
other stuff. The key here is the ground and getting
it to react.

Also frequency may be 20kHz - I cant help
but thinking about lightning "leaders" and about their
progession in air in following manner:
0,000001s progession impulse
0,000050s (0,000049s?) "charging pause"
which nicely converts to 20Khz cycles

All this is only speculations and "gut-feeling"... But
watching the videos and learning construction of Hairpin
is strongly suggested.

Hope this all works out, we don't have long wait anymore
before being choked with astronomic electricity and fuel prices...

I completely agree,  with all the tests and coils I've made I've found that the coil in this arrangement is nothing more than a filter for smoothing the hash of spark gap high voltage spikes .   

I've removed and altered everything about the coil and even ran the system without the coil.    I can achieve similar results with any kind of coil in the system with varying degrees of differences.

Since my quest isn't for light, I tend to look for alternative outputs that would successfully do some work.   I don't agree with using bulbs to measure it's actual output as this can be quite decieving.   The same thing can be achieved by converting a resistive load to an inductive load through the use of an LC and /or a PFC.   Same work is done but with far more efficiency thus less input requirement.   

Don't get me wrong, I'm certainly not bashing this experiment.   As with all experiments, as this one, you always learn something from them.   This case has certainly yielded some good knowledge in a similar but different direction... I'll post more on this in the future as I progress.   

I am still intrigued by the ground connections as many are.   Alot of my experiments are based on small portions of a complete device, I seem to learn more about something when working with sections and questioning every move.    One interesting experiment I did involved nothing more than a transformer, 2 grounds and a 3055 transistor.   I used a FG with just enough voltage to operate it ( < 1 volt input to the base ).   Driving it at about 5khz the secondary was producing upward to 45 volts although the current was very low but it started a new train of thought.   The capacitance of the ground leads was difficult to measure as it was in constant change, the resistance between the grounds was 1.2k.   Remember I said the capacitance was continuously changing.....  The distance between grounds is approximately 75ft and I'm using 6awg wire.   Im not sure how important the details are but I'm trying to be as specific as possible althought everyones variables will be different....

Lighting an LED with 2 ground sources is a fairly simple experiment as well, with the LED (diode) in line and the variable capacitance of the ground - measure the frequencies... 

Fun stuff !

I hiked five miles to the bulb outlet today. They had some unmarked lamps that appear to be Mercury vapor, on closeout for $1 US ea. Here is the first test using the new lamp as a spark gap.

Here's my replication attempt.  Coil-wind is 100,25,5 (cw,ccw,cw).  As is probably obvious, I used a copper pipe for the 5 turns.  Spark-gap is adjustable on-the-fly.  I'm attempting to power dual-bar heater elements (1KW total) & 3 100W light bulbs, all in series.  Earth_1 is the mains earth, Earth_2 is from a spike driven 30cm into the ground at least 10 metres away.

It has been a bit of an anti-climax - applying power for the first time and immediately all three bulbs blew!  Checking around showed that the original 0.7A HV fuse had also blown.  After replacing this fuse with something 'beefier', I applied power without bulbs, there was an almighty racket from the transformer - which was actually starting to smoke - before the 10A circuit-breaker cut the power.  Turns out the transient-suppressor across the capacitor I had left in-situ had also gone short! (by design it appears, according to online info)  After much cursing, I realised the transformer was still alive, so replaced the bulbs but left the connection between the 2 heater-elements open-circuit (so no current should flow) and tried again.  To my amazement I saw the S.G fire up for about 0.5sec before all the bulbs blew again!!!

First conclusion I've reached is that using bulbs without G.D.T's is idiotic!  But I presumed that with the heater-elements in series with the bulbs they'd be safe.  On the other-hand, no current should have flowed the 2'nd time with Earth_2 effectively O.C.  I have made a major -up somewhere...

Another question that occurred to me and which no-one seems to have asked concerns capacitor grounding - are people grounding this or leaving it floating?  I have it floating and noticed a spark-gap forming between it and a piece of aluminium bracket I am using to secure the wooden coil support - there's about a 2mm gap between the two...

Hi all
Another day of hard testing.

no time to detail everything now

but in resume

i wound the coil as per WOOPY C, the inductance goes from 0.02 mh to 0.076 mh  but no better result with the current draw.

Than i changed the center rod as per JLN nothing better

than i tried a lot bof grounding and antenna. nothing remarkable.

than i shortcuted the SG no big difference,

than i bypassed the complete coil but let the 2 ground and the sg. And big improvement. i could go down to 2.7 A for full brightness (comparison with the terst bulb)

the gap must be very fine tuned to get this results . Will redo all of this .

So my idea is that my coil is not in resonnance at all. and is more a resistance.

than i tried to insert a steel tubing and the inductance can go from 0.076 mh to 0.295 mh, and try moving slowly, but no resonnance.

Any suggestions ?

good evening

I have idea for making another kind of coil that is simetrical. Why having primary and secondary together: can you do test : connect big low turn wire coil in series with load and two grounds, but disconnect it from primary ... and tell the difference. Also primary cap must be such value t han it makes LC paralel  resonance with primary and no current will go.. 
One man here says earth grounds have capacity of its own .. it should be tuned to primary.
