Space Elevator Update

Recently I found a nice round-up of the state of building a tower into orbit, the only sane way to get stuff up there. Here are a few highlights:

• a space elevator could be built on the Moon using existing materials
• LiftPort has been resurrected and is working on this right now
• carbon nanotubes could be the "diamond thread" that A C Clarke described in his novels
• International Academy of Astronautics says that a space elevator "seems feasible"
