- In "The Fountains of Paradise", Arthur Clarke has his "beanstalk", aka
- the Orbital Tower, coming down on an island which is almost, but not
- quite, Sri Lanka. He had to move it somewhat south of its actual
- position to get the its high peak (known in the West as Adam's Peak) on the
- equator.
-
- Clarke also had his tower made of that famous variety of unobtainium,
- monomolecular filament. Assuming he'd done some basic estimates, you
- have to figure that's the kind of tensile strength you need for a cable
- 23,000 miles long. He also had a captured asteroid stuck out on the
- far end as a counter-weight, possibly at a height beyond GEO.
-
- As far as real peaks go, assuming you really need one (what's a few miles
- difference worth in a 23Kmile cable? Get the base above the weather?)
- then Cotopaxi & Chimborazo in Ecuador and Mt Kenya seem the only obvious
- candidates.
