I dunno. I kinda have my doubts. Not about the space elevator itself per-se but about the article itself. Unfortunately I don't have access to the
original article itself to judge. That requires payment so all I have is the newscientist article to go by.
There are a couple of things that don't ring right with me.
The materials needed:
To the best of my knowlege carbon nanotubes may be the answer as far as to what to build it out of and while expensive doesn't seem to be a show
As far as the high temperature super conductors needed:
I'm not sure if they would be really needed actually. There have been plans for building a mass driver to send ore to the Earth for a long time that
didn't require superconductors. If superconductors were actually needed perhaps placing them in the shade would reduce the cooling needed.
The article author is also forgetting some of the benefits of building a space elevator on the moon such as:
1) Decreased Gravity therefore less tensile strength is needed.
2) No atmospheric conditions to worry about (High winds etc.)
3) Availability of a large amount of material needed can be made there at the moon by mining and smelting.
I suspect that the author of that particular blog dismissed the idea prior to any real form of study of the proposal but without access to the article
in question it's difficult to determine.
