Carl Sagan & Gerald O'Neal: moon aluminum Me: asteroid s
This is part of a survey on my contact page.
What Could You Do And Not Stop: Farming Mechanical Calculations Live In Solitude 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. Bob L. Petersen My Search Of The Solar System For A Place To Live. How much effort would it take to get to where you could live on Mars Moon Venus Near Earth Orbit Asteroids Et c.

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. Bob L.

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. -- Regards, Mike Combs ---------------------------------------------------------------------- Member of the National Non-sequitur Society.

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. "boblpetersen" wrote in message ...

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. -- Regards, Mike Combs ---------------------------------------------------------------------- Member of the National Non-sequitur Society.

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. http://www.angelfire.com/space/where...o-be/cars.html 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. http://www.angelfire.com/space/where...o-be/seti.html Posted Via Usenet.com Premium Usenet Newsgroup Services ---------------------------------------------------------- ** SPEED ** RETENTION ** COMPLETION ** ANONYMITY ** ---------------------------------------------------------- http://www.usenet.com |

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. John Savard http://home.ecn.ab.ca/~jsavard/index.html |
