It's fairly easy to answer these fundamental questions for yourself.  It's not guesswork and it doesn't cost a lot of money.  All one needs is a cheap pwm with variable frequency and pulse width and cheap inverter circuit without transformer to explore the relationship between frequency and pulse width or gating.  I documented what I did in the thread ca 1234774.  AC can be used if one treats the wfc as a center tap transformer with 2 positive legs and a central ground leg.  2 or a multiple of 2 sets of tube sets are necessary to do that.  I used 6.  I have room for 16 in a 4 inch tube and 3 points for support of the array.  My output measurements were unimpressive to me at 12-14 volts.  I expect better results with voltages of at least 20 and water circulation between a reservoir and wfc.

i was referring to the gating as triggering the resonance in the manner that a spark gap triggers resonance in a tesla coil

Hi Donald,

We may be talking about different things.  Gating is sometimes referred to as pulse width.  Tesla's disruptive spark gap is something else.  It has unusual properties in a circuit that can be seen in the hairpin circuit.  There's a few replications of Karl Palsness' circuit and they all do the same weird things.

Ok so why not try out your theory and experiment ?

I believe all the circuits and schematics for exactly such a thing are on this site and can be made at home .

Hi Dankie, I reported my findings elsewhere here.  I intend to explore other ideas further soon.  I will report here findings good or bad.  I get a drill press on Tuesday coming up so I can get on with a new build of a resonant cell of 16 tubes.  I found that attempting a build by hand wasn't possible (by me) as the clearances between the tubes are critical and all the sleeves have to be on the money otherwise shorts occur.  And you're right everything is here it's not voodoo science as far as circuits go.  I will be following Stan's instructions more or less.  Lawton and his crew were close but they didn't have enough information.  I never got any buildup on my tubes as water cleaned the tubes (and rods) as the water was processed.  They were always clean every time I took the cell apart for inspection.

16 tubes for a resonant cell? sounds like fun!
each tube set has to be driven with it's own VIC and frequency though

I don't think Stan immediately jumped to his individually driven resonant cavities.  My purpose is to attempt to insulate the tubes and prevent electrical leakage much like dry cells do.  Since I'm using ordinary tap or distilled water pumping isn't that critical as far as internal components of the pump go.  The tubes act as pumps as well by themselves.  It's not corrosive electrolyte.  It won't be that much fun :p

the only time stan ever ran more than one tube was when he used the alternator, all VIC's were for one tube set only. even his brother Stephen used 2 alternators for 6 tubes where each tube was driven off of a single phase. I think your 16 tube set would be awesome, but i just wanted to point out the research behind making the decisions, because you can spend a lot of money on a cell, it just depends on what you are trying to replicate and which system you are experimenting with... and the delrin insulated resonant cavities were always small and individually driven, and used over 1000 volts.
