Webmug what is your container capacitance? relative to the inner tube.
 
Wound a piece of aluminum foil on the outside of the container and measure the capacitance between the inside tube and outside of the container. Should be pretty much the same for the outer and the inner tube. but take the inner as the good one.


I think that having other tubes inside having way to switch would be good so we could change the capacitance i think, however i'm not very sure cause as water is also a conductor i'm not sure if the area of the capacitor in the inside is limited to the tube area..


This outside of the contained will be the ground you see in the VIC. Than you will have the resonant frequency from tx5 and the container.


I think that you should not use a 100 ohm resistor in series, if you work from 12v. This would be good if you work with 200v to limit the current and i think you should not get more than 30ohm... you must think about the voltage drop. if you have 100 ohms and you are using 100 volts and 1 amp flow you will have less than 1 volt going to the primary.   


I think that ferrite is ok, I will try also with that, as i have interchangeable coil formers.

Ps i'm now only winding the tx5 tx4 chokes to make some tests as i already had a coil former having 200turns with taps every 50 for the primary and another with 600 turns for the secondary...


And adjusting the core laminations number and or gap i think will be easy to find the right configuration to  achieve the resonance..

wfc capacitance is 1.8nF
I don't follow the 'ground aluminum foil' theory... (not tested) capacitance will be between the inner rod and the outer tube.
Dielectric between them is water.

The 100 ohm resistor is used to switch the MOSFET. When I lower the resistor value I don't have 50-50 PULSE square waves.
Lowering to 30 ohm could be possible, but it depends on the coils.
I know my current going into the primary is too low. I wanted to use a transistor as a switch for the primary but I can make it work. Maybe you know a good driver circuit. TIP120 doesn't work...or I'm doing something wrong.

I bought this new driver witch is called IR4427 seems very good, it is also easy to find, you can drive with only one mosfet or in half wave bridge mode.
(this has an inverting and a non inverting output)


you should have a 100 ohms resistor between the gate of the transistor and the driver output,  and a variable 5kohm variable between the gate and ground so you can adjust the mosfet transconductance (on resistance), to not simply turn it to maximum on. (controlling the current or input impedance)


Maybe simply adding a capacitor in parallel with tx5 will be fine, however i think that the electric fields in the water bath would benefit if the capacitor is actually the container. Even the self capacitance of the coil could get it to resonance but the frequency would be very very high.


By the container capacitance i mean that being the container a dielectric and water a conductor (also dielectric) ( and being inside), If you just provide another electrode around (outside of the container) you form a second capacitor. (simple kitchen aluminum foil). Than you have the capacitance of the tubes ok 1,8nf and that of the container that will be in the pico to nano faraday range depending on the volume of water and the size of the electrode around the container (virtual isolated ground). (i think that as water is conductive to a certain degree, the only thing that matter is the volume of water and the size of the outside electrode.


I'm using now irfp460 mosfets, but i'm also planning to use tip3055 cause is bipolar and faster thus..


I think that if we want the driver to drive a bipolar we should make it in stages, maybe first one having a 5kohm resistor between the driver and the base and thereon reducing gradually in the following stages to have the desired current. I think that this approach is far better than my irfp460 cause the speed of switching of this transistors.  I'm going to make everything modular so i can change things like power supply, the vic, the chokes...


In the vic impedance network you see that he show the coils having a capacitance in parallel with them, witch can represent interwinding capacitance but can also represent what i'm proposing cause giving his own words, electrical insulated housing...insulated ground..., and his drawing of the earth reference in the drawing in the patent only confirm where my guess is going.

I was winding some coils here and just thought of something, If we just copy the vic like he described, we will never succeed cause the vic is matched to the cell or water bath. So the only way to go is to understand how to match the resonance for the specific cell each one has. i think that in sequence with the charging choke tx5 a variable coil can be added in series just to tune. This can be made with insertable core, or moving wiper. But I think that the bigger part of this inductance must be on the vic as to perform the amp restriction, pulse doubling, coherent voltage transformation...


Thus not only 100 turns 200 turns ... but his goals were important like in the patent where he say the secondary should be designed to have a maximum voltage of 2kv...

The driver I now use is shown on the right (MOSFET drive)
The other one doesn't work, should work. I think it needs a drive transistor for more current from TTL chip.

After years of testing, i prefer a transistor and NOT a FET.
Fets sometimes create some kind of bouncing resonance and transistors dont in comby with coils etc....

Not sure how to explain this in a better way.... 8)

Yes i have the impression that bipolar is better.


Yesterday was my first lecture.


I learned that any field has energy!!! and that there is vacuum and empty witch are two different things, the vacuum is full of quarks and anti quarks and the empty is empty, but has a certain mass and energy even being empty.


I learned that a field has a weight cause energy weights. A charged capacitor is heavier than an uncharged one just because of the field.


Inside protons you have 3 quarks each quark has a mass of 1 and empty has a mass of 7 and the rest 90% of the weight of the proton is pure energy kinetic or potential.


If boson particle really exist all this is than is bull shit.   


Any way,


Meyer sai Mass destabilized atom this mean charged!!!


I keep thinking here and man i think the vic will be for real very soon.

You are on the right path
