Does faraday cage to block out radio frequencies or static electricity?

Both.
It also blocks high-frequency magnetic fields, via opposing eddy currents and/or flux shunting.

Verpies,
Please explain us how we can have a HV tank circuit to accumulate energy if spark gap is transmitting it all around and we have a mA power source behind our apparatus.... is there any way ? could magnetic quenching be related or rotary breakers ?

If by "HV tank" you mean a parallel connection of a capacitor and an inductor, then any EM transmitter of suitable frequency in its vicinity will induce sympathetic oscillations in it.  The amplitude of these oscillations will increase until the internal resistive losses of the LC tank come into equilibrium with the power delivered externally. (related to the Q of the LC tank).
If the tank had no resistance (infinite Q) then the amplitude of its oscillations would increase indefinitely, but not faster than the energy delivered by the transmitter.  The LC tank can accumulate AC energy and concentrate power, when abruptly discharged, but it cannot create energy by itself.

Yes, the spark-gap can act as a broadband EM transmitter. The shorter the spark-gap pulses* are, the more broadband the transmitter is.  Broadband transmitter has higher probability of matching the self-resonance frequency of the LC tank than a narrowband transmitter.  However if the self-resonance frequency of the LC tank is known and constant it is more efficient to pump it only with that frequency rather than throwing a broad range of frequencies at it.  Broadband techniques are only better at hitting a "moving target".

[ *Magnetic quenching and rotary interrupters decrease the width of the pulse in the spark gap, effectively increasing the broadbandedness of the spark-gap transmitter. ]

P.S.
If you do things like Wesley does recently, then you can stimulate beta decay in matter with the low-power spark-gap broadband transmitter.

The electrons coming out of such matter decay are roughly million times more energetic than ordinary conduction electrons in a wire and carry a lot of energy.
...but, the energy of these high-speed electrons comes at the expense of matter - not from the "ambient" or "Earth's electric field" - concepts, that are cherished by so many people here.

By placing rod through ring we have a 90 Deg mechanical phase shift.

But do we have a 90º electrical phase shift ?

Hello guruji.

Very interesting sketch. This is the so called "Capacitive Inductor" I'm sure I have seen this before on one of the Russian forums. Could anyone translate what is written it may be of great help.

The two way switch is also interesting as it seems to bring in an extra capacitor. I wonder if it is synchronised in some way? A bit like the Parametric generator?

Cheers Grum.

Yes that sketch is interesting. Yes if someone can translate would be better.

That the kind of capacitor you have to make, to fit the resonant frequency and the coil.

Elementsix thanks for sharing. That foil cap can be used as a variable cap? Where it should be used in kapandze circuit cause primary and secondary coils are attached to each other in the schematic that I followed.

Anyone can see that this forum has been a social network of clowns, Government trolls, experamenters, and those who wish to learn, and seekers who wait for all the work to be done so that they can create a replication.  Which the last one is the most, which there is nothing wrong with that.  It took me 2 years to get my head around all this.  If you want to start with a device thats like the 2004 TK device and have a point in which is already working, but still not nearly as powerful.  Current Resonance is where you need to start.  I wrote a few days back that I had gotten 2 amps more with a resonant setup.  I had a 12volt 110 mA input and got a little over 2 amps out.  I have a tesla type coil.  The primary and secondary are in resonance.  But it was very very hard to tune it to work.  The capacitors used have to be in the pF range.  I used mica sheets with aluminum foil, layered to a nice sized cap.  The mica has the best resonance that is needed for this type.  You could probably buy expensive caps, but I don't  have the money.  I don't always get it to work constantly, but I'll get there sooner than later.  I used square wave excitation, sine wave excitation doesn't work for normal CW, but when you pulse the primary with a sine wave and match it to excite at the peak of the wave it seems best.  But without the spark gap, the current and voltage buildup at the resonant frequency (that is best around 50 Hz, for the website experiment below)  the damage is great. It seems to only power resistive loads, like incandescent lights and heater elements.  You don't see TK use his device on anything but those 2 resistive loads.  That is why TK used a circuit controller to change the frequency and vary it when the load is put onto the coil and  when there is no load and why the spark gap doesnt always fire.  The buildup of current is being used or ending up in the ground.  Srry If I didn't explain it right, but I know it works and here is a simple page that has an easy test you can do.

Hello elementSix,

Please answer just one question for me. Are you actually able to see a Resonant rise in potential with your setup? As per attached link. Because try as I might with every cap and coil setup I have played with it only goes one way....... Down.
IF yes. Do you atribute your success to your special capacitors?

Cheers Grum.

But you do have a phase shift.
It is equal to the time depicted by the distance between the two yellow lines.  Note that the two green dots are offset in time (phase shifted).
The red line is a descending ramp and its slope represents the rate of change of the output in response to the input. 

P.S.
You input is not a square waveform. It is a rectangular waveform of low DUC.  For longer input pulse widths, the phase shift would be larger.

Please read page 75 on from this book please. It talks about the Tesla transformer that I have pointed out. Actual experimentation has been done on this and it talks about the results. A higher amp output to amp input is claimed as well as a voltage increase.


 It gets heavy into the math but try to follow it.

a Radiation comes from unstable nuclei.

Not necessarily. You just proved that in certain environments (e.g. inside RF fields) even normally stable nuclei can decay.
There is another way to look at it: The EM environment affects the stability of the nuclei.

There is more evidence of this influence here.

P.S.
The Miles Mathis paper,  I recently quoted, explains a mechanism of the neutron decay as a collision with external electrons/positrons, suggesting that beta decay always has a cause that is external to the nucleus.
