Default Carl Sagan & Gerald O'Neal: moon aluminum Me: asteroid s

This is part of a survey on my contact page.

All of The Above

Carl Sagan and Gerald O'Neal proposed building aluminum spheres build
from ore refined on the Moon and then shot out of a mass driver to a
station in orbit around the moon. This aluminum would then be taken
the geosynchronous orbit around Earth to be welded into large spheres
people could live in. Just the number of steps in this part shows the
complexity of this type of operation.
If one was to used to iron nickel ore in the asteroid belt to make
steel which is much easier to process the operation would be much
simplier. The thing is one would have to do all of the above even on
the ship on the way to the asteroid belt. I was not planning this for
anyone else I am just asking what you thing.

Who is Gerald O'Neal?

Gerald O'Neal past professor at Cornell University 1970s 1990s gave a
demonstration of the mass driver to show that it could be possible
along with other work on the project. Was "presented" to the by by
Carl Sagan in the late 1970s. Carl Sagan also at around that time
introduced the world to Stephen W. Hawking. Stephen hangs on inspite
of his problem but sadly Carl Sagan and Gerald O'Neil are both gone
now.

Oh, him. Well, other than it's Gerard, rather than Gerald, O'Neill
rather than O'Neal, and Princeton rather than Cornell, you got
everything right. About on par with your other posts.

Another error is in the assertion that Sagan was supportive of O'Neill's
work. Sagan was too much of a socialist to get behind anything which might
involve some wicked old corporation making a profit off of space.

If you're going to construct it in space why not just sling clay up there
with mass drivers and construct clay/mud/brick spheres. Might offer more
protection from radiation too depending on how thick you make it.

There was one researcher who got a paper published in the JBIS which said
that the aluminum approach might be an example of "aerospace thinking", and
that if the goal is a permanent habitat rather than a space ship that cement
might be a more sensible material selection. (Although what he was actually
talking about was closer to cast basalt with rebar.) His argument was that
after having built the pressure vessel out of aluminum, you have to slap a
layer of slag on the outside about equal to the mass of a concrete wall over
a yard thick anyway just for radiation protection, so you might as well
build the pressure vessel out of such material and save the bother.

CRC and the aluminum approach to life in space tanks and a lot more.
The folowing is from a review of the CRC handbook of Chemistry and
Physics and my thought on tank designs. Aluminum has the nuclear
property that all its decays or breakdowns are very fast. This means
it will be very radioactive but because of the short half life it
will become less radioactive or cooler quicker. Iron or steel half
life in years aluminum days to weeks. It is a difficult question to
ponder.

The sphere Carl Sagan talked about were made from 14 inches of
aluminum. The mass driver was to shoot 200 pound shots of refined
aluminum.


Bob L. Petersen

The sub-frame and motor which was the start for my designing of cars
was front end heavy. In fact it would have made a better tank, so
there were so early small tank designs based on it. The pages show a
honestly how primitively it all started.

The fact that I wanted to go into space and live there without being
detected and some of the equipment I thought of using, are used in
this page to give possible reasons that SETI might not be able to
find detect intelligent life in the universe. Hey it just does not
want it's noisey neighbors coming over.

You're right. Iron is magnetic, so it could be shot from mass drivers
without buckets.

But the Moon is closer at hand than the asteroids, so the trip is
shorter, requiring less of life support. We haven't been to Mars yet.

So it may be a good first step.

I always thought propulsion was the first step.
