I was half joking on an earlier post about the nuclear-powered discharge.
I'm guessing since the charge is stored electrochemically, it would
discharge alot faster than a battery, but still alot slower than the usual
film cap, even into a dead short. You'd have to reduce the charge voltage to
2-3 volts to keep the quarter from turning to unrecognizable shrapnel and
with that much capacitance the energy level is very sensitive to charge
voltage. The inductance of the work coil would probably slow the discharge
even more (less skin effect on the quarter would heat it more (maybe even
melt it instead of crush it), bad if you're trying to keep it recognizable).
Similar problem with a rail gun. It would take impractically long rails for
the projectile to get the full push of the discharge. Also, resistance of
everything is a major concern when you're using low voltage, huge current
(bowling-ball-sized projectiles anyone?).
