Elevator Going Up!

I like the idea of space elevators - and not just because I (sorta kinda) work for a - or the - company that is going to build one. When other people notice it's keen.

An Earth-to-orbit elevator (sometimes called a "Beanstalk," a "space bridge," or an "orbital tether") is one of those ideas that, at first blush, sounds almost too ludicrous to be real. After all, we're accustomed to thinking of rockets as our only way into space, mixing danger and adventure; taking an elevator into space sounds almost boring. It turns out, however, that a space elevator is not only plausible, it's potentially revolutionary. Perhaps more importantly, given all that has happened in recent days and weeks, the notion of a space elevator can provide a bit of almost giggly optimism about the future.

The present might look grim, but within 20-30 years, we'll be taking an elevator to orbit!

Very good images are linked in that WorldChanging article.
