In his 1979 novel "The Fountains of Paradise," Arthur C. Clarke speculated on the creation of an elevator to space, bringing payloads to a satellite in geostationary orbit. In the last generation, determined researchers have labored to turn that speculation into a reality--and their extensive efforts, from cracking the engineering challenges to securing the necessary financing, are memorably told in this fascinating documentary. 74 min.
