Metal Storm is an all-solid state high-velocity super-flechette weapons array (sort of like the Reason handgun from Snow Crash) that fires a million rounds per minute but needs no more power than a flashlight battery and is based on the same scientific principles as an inkjet printer. Oh yeah, and it’s got a cousin that works just like the sentry gun from Aliens. Office supplies + Sci-fi movies = Real-world uber-weapons. From New Scientist via Neatorama.
