So the space-elevator is a not realised concept in which you make an elevayor to several kilometers height in lower atmospheres, with the reasoning that launcjing a rocket from there would require way less fuel. Now ive been wondering how you would get the spacecraft up to the top? Do you use a winch and take days? A separate elevator and... take days and ofcourse a lot of electricity? I understand tjis is still less than the fuel to get up to this height normally but i feel like im missing something here.
