What a hell does this unit do?

I saw that that thing befor....100amp spark! BUT...it was designed for F1 cars, so its not going to be cheap!


@atlasman : xobx 1? Ummm... i would say anchor! lol Its been a while sence i modded a xbox 1....

Hi ,

I was checking out S1R's youtube profile, his only subscription is to Capacitor70. This leads me to believe that he is watching for a reason, this must mean that Cap70 is on the right track!!
Just an observation...

HV

[rfsimoes]

Well is his being helping, giving directions responding objectively, documentating, posting some very good proof of concept.
He claims "I did it", the video is here, this is the circuit, I did this and that.
I say, he is definitely on the right on the right path.
GO CAPACITOR

I know that for capacitor get this results he had help from other people and for that I'd like to thank them all.
Thankyou and keep up the good work.

Well I looked a bit closer at the Plasma Cutter Thing. BTW: This circuit is available in a readable version on the "Welding projects" yahoo group.

He's using a conventional stun gun HV circuit, which actually works like a Tesla Trafo cicuit. This he puts on the welder contacts. As the HV is HF (Tesla Trafo have high frequencies) the HV will mostly be blocked by the coil in the LV circuit (which are mainly used to lowpass filter the LV, so that you get rid of the LV ripples, due to the rectification on an AC signal). For additional protection he later added a little snubber cap (not in schematic). The rest is just for switching and air, etc...

As I got interested I read abit more in this group.
It looks as the usual way to have the HV on the LV side is to just put a secondary of the HV in the LV path (sometimes) with an additional HV snubber cap, so than it can also resonate a bit on the LV side, but due to the high frequency the lv is still protected (see above).

I think it's interesting to note, that they all use HF AC HV circuits. Just a suggestion: Maybe this is the cause why they don't observe the strange effects, as others like Graneau did (and we here too).

One thing about that particular design you posted is the spark gap in the hv line.
I really thought this is a good idea. Why? When the secondary of the ignition coil creates the HV, it needs some time for that (dv/dt). If you now have an additional spark gap, which will say break at 20kv. Then immediately after the break of this spark gap, this gap will have almost 0 resistance, so that now, the  HV is on the other gap (plug). This way, the other gap will see a much higher voltage in between and especially also a much higher dV/dt.
But what I think could be really interesting about using a spark gap in the HV is, that the water would see just one side of the potential of the HV until the gap breaks. This means the water will become ionized prior to the firing.
I think this could be the key.
Graneau says in one of his papers:

[...]Accepting the general view that plasmas are quasineutral and therefore do not explode as a result of Coulomb forces, the available evidence seemed little doubt that the explosions had to be driven by electrodynamic forces.[...]

But what if we create a non neutral Plasma!!!
In the plasma state it's almost impossible to make it non neutral without that it immediately tries to expand (explode) (except you have it in a electrostatic or a magnetic trap).
But what if we first heavily ionize the water, due to the strong bonding forces in the water the water will keep together although it is heavily ionized. But as soon as we bring now the water to the plasma state or even just in a state of many very small droplets, it will expand immediately due to its ionization...

Well this is just an idea...

Addition:

This means it could even be beneficial to fire the ignition coil again after the first firing to ionize the plasma even more, even during the firing...so it will try even harder to expand...
But this time, we wouldn't want that the spark gap is closing, for we only want to ionize the water/air plasma...

Shanti, i believe it may be possible that you are the most electronically educated individual on this site.  Not saying many others are not, you just seem to really know what your talking about.  I myself can hardly spell the word "electronics"   So, my question is this, you seem to wait till someone posts, then you analyze the entire thing and post your thought on "if it is ligitimate", "if it will work", "why it will work" or "why it will not work".  So back to my question, are you just waiting and gathering information or are you planning on unleashing an ingenious circuit design here that is sure to run a V-8 engine full throttle without missing a lick on H2O?     I hope your about to let us all see what you have up your sleeve, because i for one believe you have the insight to make a fool proof circuit.
