I just saw a show on the science channel called 2057. They talk about what it'll be like in 50 years and they were talking about a space elevator. I didn't think it was possible to make one but they are saying it is. There plan is to use nanotubes and attach them to an oil rig in the pacific and attack the otherside to a counterweight outside our atmosphere. Through cintrifical motion the nanotubes would stay taught. I wasn't quite sure what they said about propelling the elevator up the nanotubes but it was something about shooting high energy particles at a solar pannel at the bottom of the elevator. The trip would take half an hour. What do you guys think?
