Capacitors for high current systems?
A one second pulse of \$ 10^6 \$ amps through a resistance of 0.01 ohms would dissipate \$ 10^{10} \$ joules of energy. That is equivalent to about 2.4 tons of TNT. A one ms pulse in the same resistance would dissipate \$ 10^7 \$ joules of energy. That is equivalent to about 10 sticks of dynamite.

Any high current pulse system must use capacitors with very low internal resistance and very low resistance conductors. In addition, the magnetic fields produced will cause significant mechanical forces on the conductors. In a laboratory, have seen fault currents much lower than that cause heavy cables on the floor to move like snakes.
