Re: Lunar Space Elevator simply isn't for everyone

Actually, Brad was talking about a lunar space elevator: one which goes
from the lunar equator to the L1 point plus another thousand or so
miles toward Earth. In the lunar g-well, this allows kevlar materials
to be used, so no unobtanium needed there.

Also, you don't seem to be up to date on the nanotube science. The
current experts are getting over 20 GPa in significant lengths. They
have also found an alternative to pure carbon. Boron nitride and
Carbon-Boron Nitride form nanotubes that are several times stronger
than pure carbon tubes and do not suffer from oxidation problems that
carbon tubes suffer from.

This all being said, it doesn't do anything about an elevator to Earth.
But hey, once I get myself into space, the last thing I'd want is an
easy way for IRS and BATF agents to come chasing after me.
