A Kapanadze generator replication - Febuary 2013

[Grumage]

Hi,


  Grooved copper seems good, Kapanadze design used copper in the coil act as part of capacitor I believe, and its actually not very thick.   I tested air core without anything in it that give me the highest efficiency but it is in normal tesla coil design, if you use copper pipe without groove, the pipe act as a huge single turn secondary that short circuit by it self.  no good. you can try to  use slightly thinner solid copper, or the grooved copper pipe will be ok.

Hello all.

I wonder if a solid Copper design is an advantage? As you suggest it would act as a heavy short circuit. But what is available from that? A heavy magnetization field!! I feel sure that these devices work asymmetrically so that the input source is not affected by the output load, but the problem is how to solve the question??

Take a look at The Old Scientist's web site, he has a vid regarding a TK coil. He is using a solid Copper rod.

Now here's a thought, Would we see Asymmetry if the Copper rod ran through some Ferrite cores with a coil sleeved over the top?

Will have to try

Cheers Grum.

Hi thanks for response. I meant a slot in the copper pipe when I said groove.Where do you connect the earth if one uses air core?
Thanks

Hi,


What I mean is, not air core, just thick wire in it , just like original Kapanadze do. I did insert solid copper into tesla coil, it works but not thick one, thicker solid copper will drop my tesla coil efficiency. 
I'm just a Tesla coil experimenter for the past 20 years, and apply the principle into this. just my 2 cents worth on opinion.


Thanks

I don't like ferrite core for that coil actually. It will saturate easily (when power up to its limit. )

Saturation of the ferrite core is deliberate and essential to the operation of the device, because it decreases the permeability to 1 and minimizes the skin-effect that is responsible for decreased RF penetration into the core.  Without it the neutrons in the core will not be stimulated into decay and the energetic fast electrons (or positrons) will not be produced.

if you use copper pipe without groove, the pipe act as a huge single turn secondary that short circuit by it self.  no good.

For an ordinary transformer that would be true, however in the SR device the brass or copper rod (pipe, or better yet, a disk) constitutes a one-turn primary winding (not a secondary).  The circular beta current induced in this rod is confined and directionalized by the magnetic field permeating the rod.  This pulse of beta current creates a strong pulse of magnetic field, which can then be coupled inductively by an ordinary secondary winding in the vicinity of the core.

I wonder if a solid Copper design is an advantage? As you suggest it would act as a heavy short circuit.

The mass of copper (or brass) does not act as a short circuit because that mass constitutes the primary winding which is the source of  the energy in that system.  If the copper (or brass) acted as a secondary winding then indeed it would represent a "dead short circuit".

But what is available from that? A heavy magnetization field!!

More like a strong magnetic pulse.  This magnetic pulse can induce huge PDC in an ordinary secondary coil.
However in order for this to happen, first the beta current must be stimulated to circulate in the copper (or brass) and that current must be confined magnetically inside the copper, by Lorentz forces.
