don't think that they will be able to get that much tether into space. maybe in 50 years but not any sooner.
You need to stop thinking rockets...If this concept were to employ rockets for power, why wouldn't anyone wishing to get to orbit just keep
A space elevator will be powered by electricity. The electricty will turn motors or generate a strong EM field, or power lasers, etc. The electricity
will be generated by any of the methods we use today...anything from wind turbines, to solar, to hydro, to coal, to nuclear fission.
The idea of simple electro-mechanical power to slowly, safely, and cost effectively lift a payload to orbit is the whole idea here. Rockets need to
lift their payload PLUS a mass of fuel 100's of times grater than the payload. With the elevator, you waste no energy on lifting fuel.
Your're right - this stuff is likely quite a few years into the future, maybe more than 50.
The cannon idea shows some imaginative thinking on your part but it's a dead end. If it made sense, someone would be doing it. If you want to see
