SWAN AND ZASHA
E arth’s thirty-seven space elevators all had their cars full all the time, both up and down. There were still many spacecraft landings and ascents, of course, and landings of gliders that then reascended on the elevators; but all in all, the elevators handled by far the bulk of the Earth-space traffic. Going down in the cars were food (a crucial percentage of the total needed), metals, manufactured goods, gases, and people. Going up were people, manufactured goods, the substances common on Earth but rare in space—these were many, including things animal, vegetable, and mineral, but chiefly (by bulk) rare earths, wood, oil, and soil. The totals came to quite a flow of physical mass up and down, all powered by the counterbalanced forces of gravity and the rotation of the Earth, with a bit of solar power to make up the difference.
The anchor rocks at the upper ends of the elevator cables were like giant spaceliners, as very little of their original asteroidal surfaces were left visible; their exteriors were covered with buildings, power units, elevator loading zones and the like. They were in effect giant harbors and hotels and, as such, extremely busy places. Swan passed through the one called Bolivar and settled into one of the hotel cars without even noticing it; to her it had just been a complicated set of doors and locks and corridors, getting her into yet another set of rooms. She was resigned to the long ride down to Quito. It was an irony of their time that the trip down the elevator cable was going to take longer than many interplanetaryvoyages, but that’s the way it was. Five days stuck in a hotel. She spent the days attending performances of Glass’s
