In fact we ran our test with your VIC and we get transformer ringing up until about 1 kHz, then it is dead and it gets terribly hot. No gas production, we tried without diode too, did not work either. 

hi gauss,
with or without load [wfc]?

@Alan: with load, it shorts out we believe. Anyway it seems like we would need in hte range of KV primary side to get any amps on 2ndary side since the VIC has like 5000:1 resistnace ratio between 2ndary and primary side.

@Steve: i am waiting for your good news!

Just some suggestions:
try without a load and try to measure with a scope over a single choke, instead of between the outputs of both chokes [because a scope can also be seen as a load]
If you want KV on the 2nd, you must tune into the self resonant freqs of the coils, this too will make 'em hot.
In other words, play around with the vic setup without a load, I think tuning for the max voltage with a load connected will give varying results and will look to you like a shorted coil - first look for the max voltage [which means no current] and then connect to the wfc.

So your secondary consists of SS wire?

With 1:1 transformer on an E-type ferrite core we also get good gas but unsure whether more or less yet. We have to measure production soon. I am pretty convinced this will become an easy OU demonstration in the future since we have not optimized one thing in our setup. And I believe we were right in sharing this asap, or else we might have gotten into trouble...

My  guess is that a 1:1 transformer will only act as a loss, and will serve no useful purpose in a pulsed DC system.

Hi Alan, what I meant is that we have about 14:1 ratio of turns and resistance ratio of 5000:1. That means about (14/500)*primary side Amps on the 2ndary side, virtually nothing unless we use kV range primary side Amps. So any resonance tuning felt rather meaningsless... We need to understand what the VIC is really meant to do first. More thinking will clarify it, at this point my limited knowledge of crystals gave me the answer it was meant to drive a massive Piezo crystal. Prove me wrong, I have no answer at this stage.

Update: just tried tap water with 2 car 12 V car batteries as input. Output increased as did the amps. With 25 V input the Amps sky rocketed to 10 Amps!! Unbelievable if you compare to a normal HHO cell with electrolyte!
This HHO cell will beat anything on the market, mark my words.

Now we tried to estimate the output at 3V input and 0.3 Amps(input 0.45 Watts). The output looks like at least 50 ml gas output per minute(0.05 lpm).

I have hard 1 lpm equals 60 Watts output.

That means output is 0.05*60 = 3 Watts

Input is 0.5 Watts to be on the safe side

COP is 6 according to this. First we estimated gas flow to 0.1 lpm and halfed that estimate.

Now we are CONVINCED this is OU by all means despite the "farmer solution"(or thanks to it). Vibration is amazing.

We will measure gas flow more accurately soon but preliminary indications are this is easily OU.

Cool, try to find out which frequency it is vibrating at, with a mic [try to let it make audible sound]. see if it is the same as the pulsing frequency
Why use piezo if you can let it vibrate at will at the desired [keely?] frequency.  
2 freq's: 1 to tense, 1 to shatter
