I wouldn't want to be near 24kJ going off in a fraction of a second, either...especially if the coil (or some other component) should decide to explode.

Nice bank you got there!
I think i should do the same, friend of mine (who works at local power station) said that they have few hundred 350VDC/3300uF capacitors taken from large inverter. I could get them for free :D

... pulls out a calculator ... hmm ... 3300uF @ 350VDC works out to 200 joules each!
You can build a heckuva coilgun with just a small bank of those caps. You could even build a really nice low-power demonstrator with just one capacitor. And then go into production mode selling them as christmas toys. Umm, no wait, there just might be some safety agency who could have just a tiny little problem with that.
Cheers, Barry Heck is for those who don't believe in gosh.

I've totally redesigned fastmhz.com into a blog where I'll be putting the juicy little tidbits relating to this project as it progresses....I'll of course update this thread time to time as well. Cheers! ~FM

So are the cans grounded???? if you are running a series parallel situation you will have can cases at different potentials.
Also if one can shorts(which is how it will fail) you will have all the other cans helping it fail that is in parallel with. I suggest you make a case of it. of some kind. Distance may not be a reliable substitute, but in combination with a case or a cover would be.

Wow, that's beyond amazing!
I can't wait to see the completed project. The switching mechanism will have to be beyond heavy duty to switch this amount of energy. If it's not designed properly to withstand such a large amount of energy it will NOT survive.
I cannot imagine the blast wave from a 24KJ short circuit.
