Description : Would it be possible to convert our assorted cyclotrons, linear accelerators and particle colliders to emit a directable stream of particles?
Last Answer : answer:Hmm, actually converting existing accelerators? That sounds highly impractical. However there are nuke-powered ion-propulsion drives designed to do just that, toss particles out the back end at extreme speeds, ... sails on the same craft I don't think you'll have a net gain of momentum.
