1. The original comment was about a CIA funding plan NOW, ie in the 1990s.
2. The basic problem is a physics thing rather than technology; the lunar
vibrations thing is `easy' since the centres of gravity of the two
systems is well known, it's only the surface effects that need to be allowed
for, PLUS there's a nice mirror placed on the lunar surface by one of the
Apollo missions; Whereas, for the satellite, it's got to allow for
a) it's own orbit
b) atmospheric effects - eg scattering
c) `noise' at the source
d) imperfect reflectors at the surface
e) cloud

and so on, BEFORE it can get a `reference' signal. It then has to subtract
off these things from the `speech' signal, and it has to do this in a very
short time.

Fusion torch? I know there is fusion on supertankers and the like, but
as a Torch-ship? where does it say that?
