I spolen to an electrical engineer there in the institute for a couple of hours, and the guy tried to understand and told me to do some simulations with multisim for better modeling than just drawing and drawing,,... hehe =)


if you check this simulation you see the drawing i made unipolar pulse... if you change the polarity of the charging choke you wont see this effect,,,


I also was trying to design something that really resonates like charging the capacitor but discharging it too while preventing it to reverse polarity and is not that easy... because when it start to discharge into the inductor the inductor (inertia) will keep the current flowing until it enter the other capacitor...

Does anybody have a VAN DER GRAAF generator?
On school, or university?

If you talk about static electriciy........

I dont know of one accessible any where steve.. I can describe one though from what i remember when i was in 8th grade.. There is a rubber belt inside of them that is movving pretty quick.. It has a wire brush rubbing the belt and that is connected to the metal dome you make contact with.. To use one you must be isolated from ground.. It allows excess electrons to build up on your exterior.. When they build up they build up on your hairs.. Since it is a negative charge building on the skin your hairs will repel each other due to the accumulate negative charge.. That what causes your hair to stand..

Does this pertain to something your seeing with the characteristics of water?

Hello

I never saw one in front of me... but in the university where i'm going there is certainly...

"If you talk about static electriciy........"What you mean?


Hey


I discovered a way to make the resonance on the simulation... Is very complex..


I needed 3 diodes 2 inductors coupled same number of turns (transformer) and 2 capacitors they are connected in such a way that the C1 during the 1° cycle charges and  never discharges except thru its parallel resistance, in the second cycle the back emf of the coil than charges the second capacitor witch in turn on 3° or =to the 1° cycle discharge into the coil 2 witch in turn energize coil 1 thus the C1...

Very cool 

To input energy i used also an inductor in series with the voltage frequency source...

I think that very close to what dan circuit it... I didn't tried to copy it i just started with a coil and a capacitor and start building the way i think it should be to perform the way i wanted to...

with 230w i can see 130v pulses on a resistor of 3kohm while having 950v going around...

Adding caps in parallel with the cell raise the Q factor... Also lowering the resistance ...

I think i understood why the coils must be bifilar...




It must have maximum coupling for better cancellation of the flux... it must be non inductive having a coupling close to unity. This allow the resonance on the inductor(s), they wont experience high voltage between its leads in my opinion because thinking of the polarity of the capacitors the both will have positive if you want. Its just there to create a secondary path to allow the resonance to happen while not discharging the water capacitor. One of the sides of the two bifilar chokes is connected to one side of the cell and to the top of the resonant capacitor, I found here in simulation that using a pulse width of 7% at a frequency of 8100Hz , using bif chokes (transformer 1:1) 10mH and a 1mH coil not coupled with the bifilar but serially connected from the positive of the battery and connected to the cell and bifilar chokes and resonant capacitor( the same connection) Than you get the back emf pulse to charge the resonant capacitor witch than discharge thru one of the bif chokes further charging the cell...




If the coils are unbalanced or not coupled well very well resonance wont happen, strangely. i think that is because you create an inductance where witch shouldn't exist. Maybe a leakage inductance i don't know... however thats why i think that meyer had the wiper arm just to fine tune the cancelation.. 


more to come


I got 270vdc on the water, no bubbles yet..gap 2mm  now i need to adjust the coils because they were not canceling. i'm using the flyback core and only the two coils. but now i'm going to do only with the dc and inductor inline... I would need to buy some capacitors because i have only few... I added a cap in parallel with the cell and the voltage went from 120 up to 250.  it was a 500nf cap but its rated voltage was only 250..


The frequency is in the audio range...
