I tend to agree, yet will rephrase to my own sauce. Transport is costly. Space transport is horribly costly. Everything that you transport will have a huge...
No. Big Red Herring here, or Chinese Whispers. This is not a rubble mining proposition. The purest nickel-iron NEA sources for metals, plus any volatiles ...
Very well stated. Phil Eklund Sierra Madre Games 2525 E Prince #72, Tucson, AZ 85716 www.SierraMadreGames.com ... From: el_slapper <el_slapper@...> To:...
Easy guys, a) Nobody has yet suggested to move rubble that isn't assayed. So Romuald don't worry about that. Whoever moves rubble will process it, whether he...
Red herring? Jan, as the title of this thread suggests, we are questioning the wisdom of having a centralized processing plant in L4/L5. The chief product of...
Ueli, Your "gut" says that water will be processed in-situ? Â I pointed out last post that if you DON'T get your water in-situ, you will expend 1.7 kilos of...
It is the value of nickel and other common metals in space (or orbit) eg. the famous $10,000/Kg that gives it its value in space construction and building an...
Phil, You seem to be addressing a number of points we've touched last year. Let me try and see.... 1. I can't seem to get the concept of "relativity and...
Ueli, And I can't seem to get the concept of absolutes across. Its not just expending 8.5 kilo of water to obtain 1 kilo at L4. Â Its expending 8.4 kilos of...
Then let's consider a hypothetical situation. Â Customer needs 1500 tons of stainless steel in certain bulk shapes (ie plates, girders, blocks) as well as...
Phil, ... oh that's the problem? No sweat: As far as I can see nobody has yet suggested to use water from Earth as reaction mass to go get rubble from...
Boyd, Moving asteroids I don't think will happen any time soon. And I would be wary of depending on convincing governments to commit tax money to asteroid...
Ueli, If in your step 4, you are moving unprocessed material of any sort from an 8 km/sec asteroid to L4/L5, then you are using water as reaction mass to move...
Phil, We've covered this ground before. I believe I understand what you're saying, and it's not that I'm disagreeing with your physics (though I do disagree...
very good points, but I'd like to answer this one, as it seems you missed something about it, Ueli : We will work on asteroids. At first, just processing water...
From James Wilson spacetrader.net "which of the many thousand asteroids, by the way?" The ones that are going to hit us if we don't! Which should put us in...

There are all sorts of possibilities. Hotels, manufacturing, settlements or even way stations to further points.  It would depend on the customer. But...
Ueli, When a person points out that a mathematical problem with your business plan, your normal reaction should be to either point out the error in the...
I think it is fair to say that such information that was cited more than once (and recently) is already in the public domain (and has been for some time): ...
Phil, Peace! I wasn't disengaging my brain. I was disengaging from an exchange that I felt wasn't going anywhere. You mention that I might be thinking you made...
Romuald, Hm.... so if I get you correctly you're saying that if we need to separate out water at an asteroid that will mean we need to get a lot of equipment...
James, From what I understand of orbital dynamics, the asteroids that are going to hit us will by far the most of them never be interesting for us. It took me...
Ueli- You missed a comparison. Earth to L4/5 vs. Asteroids to L4/5 vs. processing at L4/5. You need to compare among all three alternatives not just two of...
Agreed: 1A. Water from Earth to L4 2B. Water processed at asteroid to L4 2A. Shielding material from Earth to L4 and assembled there 2B. Shielding material...
... This is a typical example of wandering off topic. The title of the thread was not: Upporting vs. extraterrestrial resources. Â The title of the thread was...
Ueli, ... The idea to use CO as a catalyst for the extraction of asteroidal metals, as suggested by John Lewis, see: “Asteroidal Resource Opportunities...
Well, robotically extracting water, even with your simplest methods, at those distance, by remote controls, seems sci-fi to me. If we are to assume we'll not...
... And going into space and mining asteroids doesn't? And if you think about it, space travel, submarines, telephones, radio, cell phones, home computers,...
