Space Beanstalks

Imagine catching a plane to a Pacific island located on the equator, walking from the airplane to an elevator that goes strainght up—into space—talking you from the ground to any altitude up to or below geosynchronous orbit (that is, approximately 35,786 kilometers—the altitude at which an Earth-orbiting satellite travels with a velocity that maintains it over a fixed point as the Earth rotates beneath it). If you were to travel the full 35,786 kilometers in the evelator, you too would bes in orbit around the Earth—and paying just the cost of the electricity operating the elevator to get you there. And this would all be as effortless on your part, and as reliable, as the flight of skylark.
