Explosive Fun with a Capacitor Bank

Watch a 24kj capacitor bank as it discharges through various objects. Maniacal laughter follows each one and a slo-mo montage finishes it all up.

where did u get all those caps!? and how did u charge this?
I have that same question too...
Plasmana, can you remember the equation to get the amount of joules from the capacitance and voltage? I can't... Also my guess would be collection over a few years unless they have some cash lying around, I knew a guy that had five one farad and pretty high voltage caps on his shelf in his room...
E=1/2(V2C)

E = Energy in joules.
V = Voltage in volts.
C = Capacitance in farads.
I got the answer but thanks anyway.
Is this what you're after?
too many complex formulas, hurts the mind of and eith grade algebra student..... X(
dead on, cheers kitington joust...

yes I did just change your name to that... I do it a lot granted it sounds better when said...
I"m going to say ebay and probably charged through several MOT's.

Lets see, there's 100 capacitors, 10 sets with 10 capacitors in each set in parallel. It's max charge is 4500 volts at 2400uF

Since electrolytic capacitors don't go that high of a voltage, I'm going to assume that the 10 sets are in series. That means that each capacitor must be rated at 450 volts and 2400uF

lets see if I can find an ebay link to a product like that (probably sold in bulk at 100 caps.

He probably bought it somewhere else, or a listing that was a good deal earlier (like a one time sale, not a store).
wat is a MOT?
