While reading a digest of the transhumans settlement on the Dark Cast website, something caught my eye "(...)Olympus Mons, on which the first—and still principle—Martian space elevator was constructed." So this means there is more than one elevator built, doesn't it? how many are in activty by 10 AF? Also, how many elevators are still holding on/around Earth? Such elevators are 40K kilometers long, mass heavy enough to need counter-weight at the top and half-way to keep them steady. If one of them was to fall, it would wrap around the planet, hitting the ground at a sonic speed (precedents shown in Red Mars, and "Zone of the Enders Dolores, i") is there others in Sol? like around Titan? Venus (if connected with a floating city, it'd give a very nice image akin to Gunm/Battle Angel Alita's Zalem)?
