Yes the space elevator guys are at it again. It's interesting that they figure they can do this little project of theirs making a buck as they go. If they can do it I will be in complete awe of how incredible the feat would be.
Let's be honest though folks. A space tether stretching up over 62,000 miles? (By the way is that number really right or did they just accidentally add three zeros?) They are certainly aiming big if that number is right. You're talking about a space tether above Geo-synchronous orbit. Which brings to mind another question: Why above geo and not at Geo? The whole advantage I thought of having a satellite at Geo levels of altitude was that the period of your orbit was exactly 24 hours. This means you have a satellite at exactly the same point in the earth's sky 24 hours a day 365 days a year. If you're above you start to go slower than the period of rotation of the earth so wouldn't the satellite attached to the tether get dragged along?
Either way this is getting a little far fetched. I'll believe it when I see it. Until then I still think conventional chemical rockets are the best way to go.
