There's a thread in this newsgroup titled, 'Heavy lift
design for mining/cargo propulsion' which I think misses
a key point. This point is, business in space may go on
very quickly in some ways, thru use of cyberspace as a
communications resource; but moving cargo will happen
slowly. My point is, *very* slowly, and who recognizes
that detail will profit from it.
Namely, if I ship you a load of tritium in from Pluto,
it will arrive on a time scale of *years*. If I mine water
from an asteroid and ship it to my market at Terra trojan,
it will arrive in a couple of months. At the low end of
this time scale is shipping from China or Japan to the
U.S., against seasonal constraints. I.e., *time* will be
a major factor in doing business in space but I don't see
anyone talking about that here in sci.space.policy. Yet
*business* is where space-based settlements will succeed
-- or fail.
Business in space is going to make some people rich. The
first of these probably are alive today; and they will be
thinking about it. What are they thinking?

I am working on monopole and rotated emdrives as spacecraft drives.
Each is only a theory now and the rotated emdrive should be tested by
August 2008.
Each can make 15% of the speed of light, maybe if they work.
The cost to get mass into space as a commercial endeavor is always
gong to lag behind an exploration mission. ANd we have not had a
mission to Mars yet.
I am a novice in space drives, but hopeful.

All I can advise was 1% of GDP is expected to go to space exploration,
just like in the old days with ships crossing the seas.
Commercial earth lifters are the hardest thing. A heavy gravity
denies easy missions.
Antigravity is slightly possible maybe I will know by August 2008. The
emdirve, http:\www.emdrive.com is the basic beginning point for higher
efficiency designs. I rotate the tube to cause the increase in
eficency, the original inventor increases the power density to
increase efficiency.
If a drive happens as a monopole only interstellar space will be the
area explored. It should function at 15%c, but requries the whole
solar system to accelerate using the Sun's magnetic corona field. It
will never be better than nuclear engines for intrasolar system
exploration.
Fusion drives are in the cards and sort of hidden at Lawrence
Livermore National Labs.
A rotated emdrive if successful and I am a garage experimenter, would
assist in the access to local space nicely. Light cargo pods could be
lifted. Maybe a ground power station to microwave power the drives
would function for light weight pods of maybe a thousand pounds each.
BUt the odds of success are about 50/50. SO high I will make an
emdrive rotated to test the idea.
So the world appears to have a significant desire to commercialize
space, but little means for manned exploration has stopped. I hope to
change this senario.
