Eh let me know if Naudin eliminate spark gap completely and use vacuum tube or any other solid state switching mode  He is still in jungle of noise .


He he I have a letter from Tesla for Naudin :

"
If these men knew what I do, they would not touch my arrangements; they would leave my apparatus as it is.  Marconi puts in here [break D] two wheels.  I showed only one wheel; he shows two.  And he says, "See what happens when the wheels are rotated; a wonderful thing happens!" What is the wonderful thing? Why, when the teeth of the wheels pass one another, the currents are broken and interrupted.  That is the wonderful thing that happens? The Lord himself could not make anything else happen unless he broke his own laws.  So, in this way, invention has been degraded, debased, prostituted, more in connection with my apparatus than in anything else.  Not a vestige of invention as a creative effort is in the thousands of arrangements that you see under the name of other people—not a vestige of invention.  It is exactly like in car couplings on which 6,000 patents have been taken out; but all the couplings are constructed and operated exactly the same way.  The inventive effort involved is about the same as that of which a 30-year-old mule is capable.  This is a fact.

I saw the new video of Naudin.

Now is getting real interesting. I have hard time to visualize a setup of mine to work at 150 watts and bringing all those lamps to that brightness.

According him, the only change was spark- fine tunning. The carbon gets real hot as far i can see
He should really enforce some output measurment standards.


If you will allow me
I'm willing to use the Quote of your   in my new video on YouTube. I have found it very much influential.
Yes You are 100% right.
I have noticed  that  spark gap is the factor of  frequency response  with respect to resonance of secondary winding of the coil ,bringing it to voltage increase stage. At the same time it is the power not only voltage tuning factor.!!!

@stiviep: Could you please translate/put subtitles to the linked videos. tnx!

Here is a vid of my attempt at a kapagen showing the 1200watts of lights lit fully from the mains with no ground connections:  (input volts 115vac 60hz at 9.8amps... due heating, otherwise when cold it reads out 9.5amps)  Load is bank of 5 x 240watt 120volt lamps. (not high enough impedance likely, prolly need a bank of 20 lamps at 80watts each at 120volts... better impedance match to the MOT's output resistance of the secondary perhaps...)

and here is a vid showing the magnetic field (as best I could anyways) that is setup off the MOT as a result of the spark gap firing:

http://www.youtube.com/watch?v=88d8jE2lVSo

I went and looked at JLN's old ver 3 vid that showed the blue box open and the MOT has its axis vertically aligned with its Side towards the air core that is the laminates.  The side with the turns is towards the spark gap but theres sufficient distance there that perhaps the magnetic field isn't interacting with the spark gap (or maybe it is and is being drawn into the circuit there as gain?)

My spark gap is already two carbon graphite rods in aluminum ground lugs so that although it gets smokin hot, nothing melts.   

Anywho check it out and fill me in on any suggestions on what to try next.   I'm in process of stripping 6 lengths of Cat5 cable to make the "bundle of copper insulated wires" that look like they are in JLN's core of his air core.  I'm hoping this changes the dynamic as it will be 48 x 24awg wires all insulated with just their ends shorted together like seen in the pics. 

Ossie,  did you end up trying this?  was there any good result?

A heads up to some new developments from jnaudin:

http://jnaudin.free.fr/kapagen/index.htm

Less apparent power, more bright lights.

Jean Louis writes:
In the Kapagen v3.3, the spark gap has been finely tuned, a plasma cloud is created between the gap, there is no audible sound from the sparks. The input power has significantly dropped to about 153 W while the 14x150 W light bulbs connected at the ouput are very bright in spite of the surrounding sun light... The Kapagen is an attempt of replication of the Tariel Kapanadze generator. More infos at www.jlnlabs.org

Looks like Carbon electrode on one side and Copper on the other that is creating the plasma.  Interesting   

@baroutologos...

Are you talking about the D'Arsonval book that someone finally found that Smith referenced? 

Perhaps quenching the gap isn't so much about blowing out the arc as it is about having enough mass of metal there to draw off all the energy being allowed into the circuit at the spark gap, which likely would require a decent chunk of metal for both electrodes.  Then the quenching is the ability of the arc to dissipate out into the load?

I've not been able to find that book for a reasonable price firstly and second my french is horrible so I'd probably only benefit from any schematics if D'Arsonval put them in there.  He seems to have been quite the young doctor in his day. 

I can try rounding the faces of the carbon that I use for both sides of my spark gap to see how that works out...   You can see in JLN's vid that the carbon gets red hot and takes on a red tinge while running...  The way my faces of the carbon electrodes are now are just flat faces and the arc moves around within the faces and isn't held to a single point like the JLN gap appears to be with those shaped electrodes.   I wonder where he got a carbon lug like that.

Doh that should have been 240/600=.4amps... or 400mA.  Sorry Math ain't my strong suite.

There is still the noted difference of JLN using Halogen lamps as well as the 220volt rating for ALL of his lamps in series.   I believe this represents an impedance imbalance if compared against my 5 x 240watt 120volt lamps.   (total 600volts rated in series at ~1.8-2.0amps conventionally)  200/600 = .333 amps.  Curiously if I put the clamp ammeter over one of the leads going to my load I note a current of 1.18amps roughly thats fluctuating around that figure. 

14 x 220v lamps all 150watt rated.   14*220=3080volts and the amps needed for that volt figure is still just 150watts...  so 150watts divided by 3080volts is only a current of .049 amps.  So 50mA is all that his setup needs to draw in terms of "real current" from the earth at the 3080 volt series connection of his lamps.   Is that right? 

So really what maybe is needed is the exact halogen 150watt 220volt lamp load of 14 lamps to "replicate" JLN's finding directly... as that might be whats offsetting the current that I'm drawing today at 9.6amps-ish.

Thoughts?

Hello gnino this is translation:

hello The lamp is on even when the spark gap is inactive, is activated when the brightness increases, I think it is a kind of magnetic amplifier with high voltage and spark gap instead of battery
hello
