Beanstalk Blog

Rand Simberg points to a fairly new blog on space elevators.

If you haven't run across this concept before, a space elevator is essentially a cable stretching from the equator to a counterweight/station located in the geostationary orbit above the ground station. Read this for more detail.

Arthur C. Clarke first popularized this concept in his Fountains of Paradise. Kim Stanley Robinson took the concept to Mars and graphically described its vulnerability to terrorism.

Until very recently, space elevators have been purely speculative, as no known material is strong enough to bear the cable's predicted loads. But because of advances in carbon nanotube fabrication technology, science fiction authors are no longer the only ones talking about the idea. Now scientists and researchers are starting to advance the idea that this concept is technically feasible.

Professor Hall was all over this topic when it was hot about a month ago, and provides links to more information.

Be sure to check back here periodically for further developments.
