Dont kill yourself....

If I do, it will be through carelessness.  The need for extreme caution when working with, or even around, High Voltage can't be over stressed or stated too often.  This is especially true when connecting capacitors in series.  Discharging a bank doesn't remove the charge from the individual caps.  This can be used to advantage, but it also presents a potential bio hazard.

you could make a giant bank...

That's what I'm going to do.  At one kV the one MFD cap makes a tiny little Plasmoid ball.  Piggy backing it on an ignition coil's spark would make a bigger looking effect but there would still be only the small amount of proper content (bidirectional potential) in the spark.

I've got a block of the caps super glued together and will decide how to wire them up based on desired voltage and reasonable capacity.  I'll probably go up to around 5 kV with a multiplier circuit, then see how many MFD I can reasonably get.  With series/parallel wiring, 25 caps would give me 5 MFD.

Joules equal one half Volts squared times Farads.  kV squared cancels the one millionth factor in MFD, so it would be one half 25 Volts times 5, which is 62.5 Joules.

As a point of reference, my Injector Cube was fired with 500 Joules.  A 100 Hp ICE engine needs 9,000 Joules per second if all of the power were to come from the spark.

keeping an eye on whats going on here .   
ages ago I used 15Kv caps , I left the legs long and used the sheath off wire cable to insulate the legs , also glue to seal around all joins .
each cap is 2 1/4" apart
the caps were insulated good , the thing is I play with fly backs and the voltage arc went screaming over the lot

any way interesting what your doing , I may have reason to get these back into service

My capacitor bank figures are way off.  With five strings of five, the value of the bank is the same as a single cap.  That's only 2 MFD, providing 25 Joules.  I may have to dig into my two 100 count bags of one MFD caps, although I haven't verified these will hold at one kV.

Mental fog from reading too much Troll.  "Blah, blah, blah, ah blah, and oblong bull shit."  On and on, over and over.

15 kV caps should produce some stupendous results.  Energy increases with the square of the voltage.  My picture shows a 7.5 kV, 16 MFD cap not quite fully charged.

I checked my smaller caps and they are holding at close to 2 kV DC - rated at 275 VAC.  So I wired up a small bank, with 16 caps, four strings of four.  This resolves to one MFD at 4 kV.  I also wired up a 4 times multiplier, using the same size of caps.  I can now power the whole assembly with my current-limited MOT.

Unfortunately, every one of my cameras has disappeared, somehow.  This includes my video camera and the old non activated android phone.  (I had them stored in two different places.)  Therefor, the image part of my presentation will have to wait till I get a replacement.

And I've been doing some thinking.  One MFD at 4 kV will give me 8 Joules.  However, if I use the 16 caps in parallel, for 16 MFD at one kV, I'll still have 8 Joules, the way the math works out.  It looks like there may not be an advantage to wiring a group of caps for a higher voltage.  Bidirectional potentials is what produces the ionizing radiation associated with the Plasmoid effect.  If a lower voltage Plasmoid is stretched out by piggybacking it on a much higher voltage spark (the way Ed Gray did), the Plasmoid will still ionize, and magnetize, every molecule of CO2 it comes in contact with.  The longer spark will then allow for the production of an ion cascade, the same as shown in my picture.

I also wired my multiplier up for use with either polarity, by adding an extra cap at the top.  This is the same cap I can use for extracting the ripple voltage at the high end potential.

15kv is the dc rating of the caps , it was for a multiplier .  I was wondering if LV super caps could be used on pri circuit but when ever C are in series every thing gets halved......


mouser have filters to search for AC or DC caps @ what ever rating your after

rolling your own HV cap is an option ........ one Ive never taken

Even with the reduced value from series use the super caps would have a high MFD rating, which would affect their discharge time constant.  At times, this can be an important issue which requires re-sizing the inductor.  Sometimes, it's better to use a low value, high voltage cap, to get the needed Joules.

I've done this a lot, but the value is in the low nF range.  Not enough energy for some applications.

A spiral line capacitor, using vector inversion to generate HV, is also a good option.  Here's a patent which describes a winding technique which will produce any predetermined amount of energy at any predetermined voltage (for instance, Mega Joules at kilo Volts, with LV input):

Here's a simpler patent which describes the basic spiral line operation:

I only just glanced over at Mic caps , theyre 1uf , 2kv , so I assume thems the caps you have a pile of .  also theyre oil inside so rugged enough .
I havent got any MOT , I got rid of them so they werent an option laying around . 
considering my own safety . 

Ive had a hit form flyback which is HV DC , not directly but it does find its way across anything , aswell as the insulated screw driver I used!      I see FBT safer than MOT .  nothing I use is wall AC .    Ive seen guys cutting the core of MOT on net , I assumed they were going for gapping FBT and fast discharge .

this sites quite well known in HV circles =  http://www.niell.org/exploding.html
