The Fountains of Paradise

The Fountains of Paradise is a science fiction novel by British writer Arthur C. Clarke. Set in the 22nd century, it describes the construction of a space elevator. This "orbital tower" is a giant structure rising from the ground and linking with a satellite in geostationary orbit at the height of approximately 36,000 kilometers . Such a structure would be used to raise payloads to orbit without the expense of using rockets. The novel won both the Hugo and Nebula Awards for Best Novel.
