coil gun

No, this is not one of the sci-fi video game replica weapon props I keep posting about–it’s a real, functioning homemade coil-gun by Jason, aka YouTube user Larsplatoon, aka Photobucket and 4hv.org user Saz43, who has been working on it for two years. It’s billed as a “1.25kJ Coilgun,” but I dunno how that figure was computed. If it is muzzle energy then projectiles from this weapon deliver more kinetic energy than a .45 handgun but less than an M16 rifle, which I frankly doubt. But judge for yourself by clicking the embedded player below to be taken directly to the test firings at 2:50, in which various housewares get shattered and punched full of holes. I’m guessing 1.25 kJ is the theoretical maximum energy that can be delivered by the capacitor bank, and that the real muzzle energy is significantly lower.
