I like.

I watched a special about this on Nova Science Now.
Here are my concerns:
The method in which you got the cable there is extremely plausible just kinda time costly, but hey it's space we got all the time we need.

How's this elevator supposed to get there? Rocket? The special suggested a laser shot at a solar panel. That could work, but there's got to be a weight and speed limit unless it's a big laser giving off a lot of energy.

I think therefore I'm MAN.
