I am cutting corners again. I'm building a single stage rectifier 15kv in 30kv out. I don't have the budget for HV diodes so I connect 20 1000v diodes end to end (7ft long) for each diode in my rectifier. Seems to work. I haven't measured with a divider and a voltmeter but the gap discharge measures about 1.75cm. A little wider than my calculated Paschen estimates, possibly because of a Corona effect. Anything I should be conscious of or worried about as I continue? I plan on adding more stages and I'm curious if I'll get more waste in later stages using this diode method?

6-12 seconds. At 60mA, I would be charging at a rate much closer to 2 minutes given natural waste I'll incur. Requiring me to scale down my load to meet expectations. I'd prefer not to think in that direction yet. I've already 'started small' and proved concept on bread board. But as it turns out, the transformer doesn't scale up nearly as easily as the other components. Very disappointing. =(

Would using a flat wire work to increase the area? Is that what you mean by 'sheets'?

I had a lineman come out and explain what the utilities in the area were equipped with. Based on our conversation (there's a 40amp fuse 500 yards away, on the 7200 transmission lines. I can't draw more than about 120 amps on my side before I risk blowing the neighborhood switch, should they be running high draw as well. I have 2 neighbors on this circuit. I like them. So I got a 13kw generator. No prob. I needed one any how. But you're right. My charge rate ideally would be appx 0.1-0.2 hz. Of course I could resize my components based upon a known input like a HST. That's an easy thought. And it's probably my most realistic option it seems.

If I use a NST, say 60mA, my load will require charging for over a minute. Not acceptable. I imagine I might could have 2 or 3 transformers in series, each with a fraction of the total voltage amplification. There's probably a catch there too. Enlighten me. I made a crude prediction. I tested it failed. I post to ask questions and learn why. While the safety concerns are sound, saying "you're too X to do Y" is not something I heed.

Lots of cool knowledge. I'm left unphased by your personal attacks. I'll probably just get a utility pole transformer and backfeed it. Thanks.

So because I've limited the current to levels that significantly reduce the magnetic field strength, my turns are no longer close enough together to be considered a single inductance, and each turn is actually its own inductor in series? Making it one big resistor? I'll remove the bulb and the knob, add a switch and retry. Thanks for the safety tips. =)

I need full current pass through. Also, I'm not tripping a breaker since I built my fuse/rheostat console. I haven't even burned a fuse yet. 20amp. But do I need more primary windings? Here I have my phase 1 set up. http://postimg.org/image/3x87azoht/ Current is being limited by the bulb and a dimmer. Dedicated fuse, and breaker. How would I "reduce loss"?

No shame, I need troubleshooting assistance. I bought some 17kv wire, an extension cord and a toroidal core with the intention of stepping up 120 to 6kv. Turns: 100:2. (Fyi, Pic demonstrates 1 primary turn not 2) I made two 50:1 voltage dividers (together 2500:1) to measure this voltage. I should have measured about 3-6 volts after the divider. And I did. Then I disconnected one divider, I should get "overload" but instead I get an identical measurement as before. So I disconnect all resistors and get the same voltage. ~4 volts. So I get frustrated and touch both secondary leads together, no sparks. So I measure again, same low voltage. No divider. I made a mistake with this transformer but can't figure it out. So I rewound the primary to one turn, and moved it closer in proximity to the core. Similar disappointing results. Continuity of both windings checks out. I figured a transformer would be easy. What did I do wrong? http://postimg.org/image/44pw6rfy9/

So to say wattsecond (joule) can be made from a spark.Does the capacitance necessarily determine the total amp seconds needed to balance an average discharge voltage? What is the exact relationship between this Marx bank and joule output, FV=Ws? If you charge a bank in parrallel you have a different capacitance than when you discharge in series, which capacitance do you use for charge time formula and discharge joules(watts).

Lets then say that the input power is 3kw And the output must be 50MJ

We are solving for X, X is a device or combination of components which satisfies the requirements. Given: I have a limited source power (ie, 1W) I have unlimited resources to design electrical components and unlimited time. Requirement: device must output a 10J pulse. Allowances, For my math to work, the device can accept 1W for 10 seconds to be able to output the 10J during a 1 second cycle, assuming no losses, no resistance, etc. Does a Marx Generator do this? What X device satisfies this requirement?
