A strong cable lowered from a geosynchronous satellite and anchored to the ground (often with a small asteroid at the outer end to provide some extra tension and stability). This would provide cheap and simple access to space using elevators. Also called an orbital tower. (See The Orbital Tower by Jerome D. Rosen and sky hooks) [This is an old idea in science fiction and probably first discussed by Yuri Artsutanov, although it was popularized by Arthur C Clarke's The Fountains of Paradise (1979). The term Beanstalk was spread by the roleplaying game 2300AD by GDW.]
