fission. :) it can run several fuels as described in article. Battery seemed to have stuck. it's not my favorite. I would say generator. battery apparently seems more innocuous. Battery also feels accurate because the reactor will be more or less "plug and play" like a really, really, really long lasting battery that produces the same amount of power. It can also be used in "packs" like a battery. Fundamentally, nuclear, just like coal or anything else is a source of heat. With different secondary packages, you can produce electricity or cogenerate steam.
