It sounds like some of those same ideas are being revisited, @ErnieRogers! More like a station at GEO, but with the tether extending to the atmosphere. I’m really excited to see where this technology goes. With the future of space travel hinging on reliable and inexpensive transportation, it seems like this idea has some promise and isn’t just science fiction anymore.
Some people are also thinking that a material like Kevlar could handle the tension/shear forces if an elevator is executed in this way.
Question: Is this the transportation breakthrough (even if it is still decades away, at least) that you’re most excited about? If not, what would your ideal transportation breakthrough be?
