It's probably a high speed launch assist, not the entire source of escape velocity.
That sounds so funny though.
How would you even do that? Build something like a particle accelerator except it's a launching railgun the size of China?
I mean yeah why not if it means you can partially reach escape velocity with like solar powered electricity vs going the entire way 100% on burning rocket fuel
