Thx for the explanation Gunther, I've attached some scope shots to see the pulses in more detail as requested. I'm eager to hear your thoughts about them.
Quote from Gunther Rattay
The assumption is made that it takes 10 kV for a 10 electrodes serial cell to get over the ionization point and create gas.
If I'm not mistaken, it was also Ed Mitchell who suggested that to achieve these voltages for 10 electrode pairs, you would need 10 VIC's, connected in series. Has anyone tried this to your knowledge?
A question to forum members: Would it be safe to assume that one VIC should be able to drive one electrode pair?
Quote from Gunther Rattay
Once he created a huge amount of gas and then the transformer failed.
Is there any documentation on the type of transformer design Ed used?

When you introduced an air gap between the cores, the voltage across L2 (-) actually becomes lower (fall) than without the air gap?
Or with the air gap  the voltage across L1 actually becomes higer ( rises) than without the air gap?
Well, I've ran some more tests on the influence of the air gap running of a battery to avoid ground loops. When the core has no air gap, both signals are identical. Introducing an air gap does lower the L1 voltage slightly (see attached scope shot). So there is an influence, but at this point not nearly enough. I'm going to try to strip of 5Ω of L2 and add it to L1, see what that gives me. I guess my previous statement was incorrect, must have misread the results.

I clearly need some sort of mechanism to control the air gap more accurately. Right now it's done manual and inaccurate. I'm going to try to build some kind of rig for my VIC, similar to Russ' adjustable bobbin design.

Thank for answer and sharing results.

Do you see the frequency doubling in Henne scope shots?
7,76 kHz in the primary and 15,5 kHz in L1 and L2.
thank

He did. It showed that it´s difficult to build them all exactly the same so that they resonate like one. Idea was to go with cheap and small cores.

I see it, along with the token "sperm wave".  Looks like Henne is right on track.

Yep, no power consumed there.

So, is anyone still working on the WFC/VIC?

Did we all give up around the same time?

I've been trying to get back into it but life keeps getting in the way. Right now I just don't have the space to set things up.

Ronnie, Russ, Matt, etc.... you guys still out there?

I haven't given up. Just not enough time to really get into it.

I'm still here; so is Russ, but we're off in a different direction at the moment trying to figure out how coils, induction and impedance really work.  Meyer's work seems to require that these fundamental concepts be well understood before any WFC progress can be made unless we take an accidental approach which hasn't worked all that well so far.

I thought Nav was still engaged and I did get a note from Ronnie fairly recent that his lab was all setup again, kind of hoping he would jump back in with some new angles to approach things from.  Guess we play it by ear.

Awesome, I'm hoping to get my stuff setup again in a month or so..When I do I need to get back in touch with Ronnie so I'm glad to see he's still around.

I feel like I was close the last time I was messing around with it but I need to make another VIC. Problem is free time is rare these days and winding those coils takes hours on my lathe...Might have to save up for a coil winder.

Last time I got things going I made some really good notes on my testing, there's alot to go through but I think there is some very important information there. Also, I've been working on a modification to my cell... When I get it done I'll be making a video on it.... time will eventually solve these problems I hope.

Trust me, I understand. I haven't even had my stuff setup this year....Last time I was working it was mid 2017.

I just recently started noticing all the junk I've collected with this hobby, just gave away about \$150 of wire and other crap that I realized wouldn't work on a vic... still got about 20 coils, cores, and bobbins that are all two small or not the correct specs to make a vic out of. Hopefully getting rid of old stuff will make it easier to get setup again.
