While coil guns may not be as efficient as deflagrating gunpowder, it is definitely cool to think that one can fire high speed projectiles silently using only some wire and a power source. If more research is done and efficiency is increased, asynchronous linear induction motors could definitely revolutionize transportation, weaponry, and all sorts of other industries.
