Wh'hoo! I believe is the first word that sprang to mind when Nature magazine linked me to this. It's not an actual space elevator. Just the fact that there is a serious bunch of professionals that are actually talking about building a space elevator is waaaay cool. Read the wiki page if you don't know what one is, basically it's a cheap way into space. We're a long way from building one, but it's good to be talking about it. Something for people to dream about as Neil de Grasse Tyson would say. Or at least, I think he would.
