thus my line about "a tame comet". If you can bring metric buttloads of water
to L5, why not the Moon? I guess landing it safely would add a premium.
Stupid gravity wells.
BTW I looked at Zubrin's _Entering Space_ in the bookstore today. Had some
interesting stuff -- I'm now more confident of an Orion Drive being able to
hit tenth-lightspeed (esp. as he's not a big Orion fan.) He dismisses
O'Neill's ideas cavalierly, though; I didn't read carefully, but it seemed
like he pulled rebuttal cost figures out of his butt, whereas his own ideas
got detailed calculation.
Seemed odd that he had a brief "wild card" section on robotics, biotech,
nanotech, and picotech, but not AI proper. Didn't mention Savage at all, and
savaged the inferior concept of Dyson Sphere (solid shell) without mentioning
Dyson's actual vision (the swarm.)
I got a "negative attitude" impression from my skimming, but this might just
be from my favored ideas getting savaged or ignored, plus his bitterness about
the lack of space research. Which I can understand, but it's not like we're
actually stagnating yet; it's just that the public research dollars are going
to biology and nano and the private ones to biology, nano and computers.
But the stuff on rockets and spacedrives was cool, and probably there are
other neat technical ideas there too.
