I cant' believe you guys are drawing a direct correlation from a DVD player - alternator to a ship board power weapon. It was an analogy. Honestly! The point is you can build something that can power non critical parts of a vehicle. You can make this piece small and light enough to fit into a vehicle and you can do all this with technology in the year 2007. Now you want to honestly argue that in the year 2400 some 393 years away you still can't make a source of energy to power a magnetic catapult or wave motion gun or whatever that is small enough to fit into a 250kT ship? Man I feel doubly insulted.
