Color me dubious

A portable nuclear reactor, huh? Safe, you say?

“In fact, we prefer to call it a ‘drive’ or a ‘battery’ or a ‘module’ in that it’s so safe,” Hyperion spokeswoman Deborah Blackwell says. “Like you don’t open a double-A battery, you just plug [the reactor] in and it does its chemical thing inside of it. You don’t ever open it or mess with it."

Hey! Wait a minute! What you're describing is...is...Happy Fun Ball!
