Kapanadze Cousin - DALLY FREE ENERGY

Here is something to consider. Ruslan wrote the following in the realstrannik forum (Google translation):
"Desirable to remove the energy pulse is short (150-250 ns) This podbiraetsya when configuring. 
And it's better when the frequency of removal rate multiple of the frequency of the pump.  Ie  Kacher 1.5 MHz, 15 kHz will eat !!!"

So, if we pulse the capacitor with say an IGBT at 15 kHz, that is a period of about 66.67us (66.67 microseconds).
If we take the maximum pulse width from Ruslan's recommended pulse width above of 250ns, this
gives us a duty cycle of (250ns/66.67us) x 100 = 0.37%. That does not appear to be very easily achievable.
What do you guys think? Assuming we can achieve our 250ns driving pulse to the IGBT gate at around 15kHz,
would an IGBT fully switch properly at that short of a driving pulse width on its gate? You are going to need a very fast
IGBT in the very least. Is Ruslan just talking theoretically here but actually using a wider pulse width himself? I am
inclined to think so.
All the best...

Ruslan many saying teoretical. I think he can use longer pulse. For example 500-2000 ns on drain-source. And he can use 15-40 kiloherc. With 250 ns pulse you probarly not get strong output on 300 turns winding on toroid.

Hi Menof. Yes, I am inclined to think Ruslan may well be using a fair bit wider pulse width than 150 ns to 250 ns.

I was playing with my ferrite kapagen coil with various other drivers... longer solenoid...

my original test winding was 6 turns loosly wound across the 4 inches... there were times when bumping this made resonance stop; but

I have a slighly larger toroid/abha coil that I was testing with; it's field is highly concentrated in the center... and optimal positioning was centered in the toroid, and depending on the frequency... at the very ends of the grenade long coil, any higher than the middle was bad/no output.  at low side of resonant frequency it was only at the ends, adn was deader in the midddle... at a higher resonant frequency, positining could be more centered on the long part of the grenade... but peaks were still offset from exact center....


I also used a 2 turn 5 inch loop coil I have and flatented it out; the plane of the coil also stiminulated best resonantces at the ends of the exposed long part of the grenade...


so I settled on winding 6 turns at the end of the grenade (at end of lowest layers/longest exposed coil... not on the coil, but near the end), and driving that with the signal generator is giving as good or better output than other coupling locations....

Playing with some calculations


(doesn't support code tag)

Code Select Expand



x=1

4x  = 16*4x
(3x)
2x  = 4*4x
1x  = 1*4x


The 9 turn layer is 2 9x coils... so it's in the same length, but double the turns...
would proportinatly be the same with single layers....
(inductances turns, in length; diameter assumed 2 inches constant)
9 in 2.5 = 2.4
18 in 2.5 =  9.5
18 in 5  = 5.5
36 in 5 =  22.0
36 2 10 = 11.9  2x turns = 4x inductance
72 2 10 = 47.6

12 in 2.5  4.2 microhenries
24 in 2.5 = 16.9
24 in 5 = 9.8
48 in 5 = 39.1
48 in 10 = 21.1
96 in 10 = 84.6


16 in 2.5    7.5
32 in 2.5 = 30.1
32 in 5 =   17.4 microhenries
64 in 5 =   69.4
64 in 10 =  37.6 microhenries
128 in 10 = 150 microhenries


------------------------------
so the grenade coil is in theory 1/4 of the longest coil's inductance... 4X inductance - (2x + 1x) = 1X..
although it is a ratio of squares... and I know the golden ratio is progressive squares... but turns out it's 1,2,3 not 1,2,4
the lower turn coils calculate as having lower inductance than 1/2 of the longer, more turn layer, so having it be slightly larger diameter is a good counter.


was going to try winding a coil that's 48 turns and flat another 36 counter to that... leaving 1/4 inductance... however I was also just pondering the wave through the coil... and almost want to build a 3d animation ...


if the field is located at the end of the coil, the first inductance is going to be a bifilar coil, which progressing up to half way is constructive to cause a current, and a slight low pressure (high potential) is in the join between the long coil and next layer... the next stage is befuddling; the induction on the reverse wound second layer is going to want to make a current in the opposite direction from that which the votlage wants... (including the voltage in the link between the coils) and I don't know how it decides which wins..
------------
I'm not sure why the other coils I tried were so bad....
at a frequency of 266Khz and 1.2mH, 324pF capacitance would be resonable for the wire/bridge rectifier/LED load... so there's room for capitance... I ended up turning my load 90 degrees so it's +/- LEDs to a 'ground' which is the other end... across the BR the capacitor stopped charging, which is when I kinda realized I was turned...


With the ferrite any ground is as good as any other ground; it doesn't require a connection to 'special' ground...

Again on tuning process of my grenade coil.  Just tried to play with the pitch of the anena and it has massive impact on the resonance frequency (as the capacitance change)  Smaller pitch just raised my frequency for more than 100KHz .  That's lots off wire I can add to my kacher to increase the voltage.

I am thinking now to print some clips/stripes which will allow me to gradually tune the pitch/frequency.  On other side i do not see any effect of that ferrite rod. I guess it is there just for effect

Guys, I think forget about that Ruslans antenna. We really should follow Tesla's way. Huge difference. With this torrid anntena my frequency jumped up by couple hundreds KHz and the field around is more intense.
