Wouldn't work in space, but just wanted to share something that could look really cool.

a traditional railgun would probibly work better in space. theres no atmosphere to turn into a conductive plasma so theres no arcing. in an atmosphere arcing will eat up a rail in no time.

Those would be some insanely huge lasers...
