Short answer:

Nothing happens, you get frustrated, increace the power, it burns, you cry.

Long answer and safety rant:

The Groucho Project that the Group is building is a small Marx bank (get 
it?). You have to understand the basics of how they operate.

A Marx bank is a high voltage, pulsed DC device. A bank of High voltage, 
pulse duty caps are charged while hard wired in paralell. When the voltage 
reaches a set level (controlled by the spacing of several spark gaps, with 
the bottom one often a triggered gap) the caps discharge in series. If you 
have a bank of 10 caps in a Marx array and each cap is 100,000 volts, you 
only need a 100,000 volt DC power supply to charge them. But when they 
discharge, in series, you get 1,000,000 volts.


Then you start over, this takes a LOT of time compared to the TC world where 
chargeing takes 1/120th of a second.

A Tesla Coil is an AC device (ok ok ok I know, but let it go for this one 
ok?) and if you use DC rated caps in AC service you'd better have a bigger 
supplier than I do (and I have corporate sponsorship for my caps).

There is a possibility that you COULD use a Marx bank to power a single-shot 
coil, but it would be a LOT of work for a little effect. The Marx bank makes 
great arcs on it's own.

I STRONGLY, FIRECELY, RECCOMEND you spend a month reading before you pick up 
any HV gear. There is a website that has a TON of textbook type info on 
everything from the basics of electricity to Lux-Level theory and esoteric 
stuff that makes me feel REALLY dumb.

I can't find the link guys, what the URL on that site? It's a GREAT site and 
I reccomend it for ALL newbies, especially RQBauzon, from the questions I've 
seen you ask, there's gonna be a pool going on your life expectancy if you 
get a couple NST's, and I do NOT wanna see a new student get hurt, or 
killed. I'm the ultra-paranoid-safety-freak-of-science so that's how I see 
it. I put out 5 fire extinguishers for a Tesla Demo today, though we've 
NEVER had an unintentional fire. I'd rather have them there and not use 
them, then vice versa.

Have fun, and don't get dead.
