After watching that vid I figger I could try a different field.

I put this together and got an excellent stable arc, albeit with near saturation baking soda solution.

Still working on gittin' the amps down.

Turtle:
You have a good idea there. What if you tried just an eclipse shape that could be adjusted for closeness to the tungsten....think you might be too far and using more amps...possible. Experimenting with distance from rod might be worthwhile.

IH was of the opinion that the partial field would disintegrate rather quickly at the rod contact.   I'm gonna work with 2 feeds on the field.

Also, warlock's arc was anything but stable, and mine was rock steady.

Methinks the relationship of rod to field, applied voltage, and width of field have much to do with performance.   This was the first of a skinny-pipe design that proved the perf-plate field will work, at least initially.  Much more ahead.

I gotta review all these pages, cuz anomalies I seen need some explaining.   Much of study ahead, and yes, the variac is a must.   Jes didn't have it at the lab.  Step-up tx as well.

At least I be a-headin' in the right direction, uh huh.

More later.

Turtle:
I think you have a good point on the partial field argument but not sure of actual mechanics. For example, does a bigger rod make more h2? True, you would have burning just on one side of the rod with partial field, but it should last as long.
Anyway, look forward to more developments.  Its getting colder and need to refine the h2 heater

Hi just some info that may help

An RF signal at 13.56megs into an RF amp with a 250v DC supply will give you a chance to done what you want. You will need the high voltage mosfets with a  rating of 1500v and able to run on 6 to 8 amps   the RF amp will peek to peek at 1200v with low amps to start the arc then it will drop and the current will rise.
 
 I am working on two projects in and around this.
I have seen the reports from the japs doing this stuff and they had all the gear and the technology but still failed to get any real output of gas.
DO NOT USE ANY FORM OF SALT IN THE WATER AS YOU WILL GENERATE CHLORINE IN THE WATER AND SOME CHLORINE GAS
The water can get up to 1200ppm of chlorine just from a small amount of salt
I have had years of experience with electrolysis in water treatment.

BTW,AP, you into desalination?

I do the dirty water thing, wastewater treatment.

Hi keithturtle
 This is a follow up
 The mosfet does not actually turn and off it's used as a c or a d class amp preferable as push pull.
The signal RF input into the amp is then amplified usually just short of 4 to 1 ratio.
Just like your amp at home that plays music
You can apply this to the standard electrolysis as well but take care.
I am putting together at the moment a demonstration unit for a meeting that I am speaking at, this is a high voltage pulsed power three cell units. I am not sure how it will turn out but I am experimenting again after a few years. I will be talking and showing the break down of the Myers electrolysers there were some interesting things that have come from this, it also has show up some possible flaws.
My main interest is developing my OZ Injector this has got to the build stage and some parts should be ready soon. Mean time I am looking at a few new approaches and explaining things to our followers at Climate Technology Solutions,

Once again, the HOPE cell is concerned with the creation of gas in addition to heat production.   What I'm after, at least initially, is the heat.   The more gas I can burn (reconbine) in hte plasma process, the better the efficiency, I think.

Still working on it.

aussepom, thanks for the RF info.   I'm about as ignorant as a turtle's plastron when it comes to RF, so there's a lot of homework I must do to grasp yer concepts.   I believe there is a way to use RF in direct HHO production, and I've aleady started fabricating a cell to drive, once I figger out what to drive it with.

It uses 2" long 1/4" rods on a 1/8 core rod.   Many of these in a cylindrical configuration, surrounding a solid 1/2" sq rod as neutral.  All contained in an acrylic tube, water injected at end, gas out the other.

Coil wraps the whole thing, RF applied there.

That's my thought; whether or not it has any basis in reality remains to be seen.

It's a long path, and time is not my friend.

I'll follow yer lead.   Mebbe that oughta be another thread, though.

Thanks again,

Turtle
