Rail Gun, full auto?
unless i am mistaken, rail guns use high voltage rails, and conduct through the rails and a projectile... not unlike jacobs ladders. if we took a jacobs ladder and made the rails parallel, they could be used as a rail gun. right? if so... what's to stop us from having a gravity feed rail gun, something that rols a ball bearing or some such metallic ball or rod onto the rails to be shot down, the moment the first projectile isn't touching the rails, the new one rolls on... say... power it with a cordless drill battery and step the voltage up with a wallwart transformer? if we can make portable tesla coils... a rail gun doesn't seem so far fetched. granted, this post isn't using any technical jargon so you probably all think i'm an idiot, but i do believe that it's possible. my knowledge of rail guns is fairly rudimentary. any ideas? it would obviously be VERY low velocity... but if you were to make it stationary, you could upsize it and run it through a large MOT from a microwave, or a transformer from a UPS or something equally massive and... well... have a fullly automatic rail gun turret-y thing? yes?
