Accumulators: A concept for GURPS Spaceships

[YankeeGamer]

I was originally thinking of space opera, in particular, Lensman style accumulators, that store energy for use in a battle, or anything else, as dramatically necessary. It seems that, if I want the "accumulators" to do both, it would need to include both batteries for long term storage, and capacitors for firing the weapons, after charging them from the batteries.

Goal is to have extra energy for whatever needs it, without extra reactors, be it for firing a weapon, entering hyperspace when hyperspace needs 5 power points and a reactor has one, but only need those 5 power points for a moment...

Medium hard science fiction to Space Opera--and I learned a lot here.

I know that model railroad locomotives use a capacitor on some fancier DCC (Digital Command Control--fancy electronic comtrol for model trains) to keep it going over short sections of dead track. Beyond that, I didn't really know much about capacitors or batteries.
