A REAL space catapult in my lifetime?!

Post  ChasingSanity on Tue Mar 13, 2012 5:48 pm

I wished for this for so many years. Use big electromagnets to push a reusable, big, hollow bullet on a long rail, climing up through the atmosphere fast enough to escape our gravity. The spin of our planet does part of the work. Purely electrical propulsion, I wonder how much energy would be used compared to the atom smashers scattered around the world.
