Concept Outline. The space elevator is planned to be built by the year 2050 with a capacity to carry 100-ton climbers. It is composed of a 96,000-km carbon nanotube cable, a 400-m diameter floating Earth Port and a 12,500-ton counter-weight.
This is not strictly true, if you are being clever. A small space elevator, on the order of 1000 km long, can be placed in low Earth orbit, with some kind of electric propulsion on-board (ion, plasma, electrodynamic, etc.) The engine operates continuously, adding kinetic energy to the elevator.
