If you want some really good ones, rumor has it that the Star Trek writers had a whole list of real and fake (but techie-sounding) words or prefixes/suffixes that they typically pieced together in threes.

One of my favorites was "Meta-phasic shielding" I think it's something they did to their ship to allow them to hide from somebody in the outer portion of a star. But I'm not certain Happy
