Hi all, Let me take a first shot at Jan's "big picture" (don't worry, I'm still putting the final touches on the first draft of our shielding milestone). We've...
Okay, while writing up the points for the big picture I kept wondering where to apply leverage. Well, here's a revamp of the sequencing: 1. Competence to...
So while writing up the sequencing of achieving competencies I have come to the conclusion that cheap rockets, telerobonautics, and tugs are the very first...
This looks thorough enough, Ueli. Essentially this substantially fits into the current framework as portrayed, it is mostly a matter of the time-scale of...
This seems to be a good place to start from, Ueli.......... This would allow the beginning of a first revenue generating process to be put in place for several...
Just off the cuff a fast response (I'm on the road again with infrequent access to the net) Â ... Jan responded: Smelting, zone refining, CMVR and inertial...
This is great stuff. Seems like there WILL BE A MARKET for removing large debris, as it's the large stuff that is most worrisome because it will progressively...
OK, Ueli, I was differentiating between CMVR processes and raw grits on one hand, and smelting and separation of junk metals gathered from orbit on the other,...
Grind the junk up, then do the CVMR on that. Should work. Â Spin casting not required with CVMR: The mould is the large body (maybe inflatable) onto which the...
Hi all, Here you are with a draft of the "Shielding Milestone". Please take a read through it. Is it clear? Is it interesting? Does it give insights? Is...
Jan, Orbital cycle times... - ahm, I believe you're in Hohmann transfer orbit think here. Remember that such orbits require a lot of mass to achieve the...
Jan, You wrote: "It may be interesting to list what can at this point be hired off the shelf. Hired equipment is tax-deductible from revenue, unlike capital...
A most thorough and workmanlike summary, Ueli! I particularly like the comprehensive bibliography of reference links. Soon adds up, hey? It helps to establish...
But vacuum depositing is going to be slow. I think it is reasonable to plan for any method that will work assuming that varying conditions and needs will...
Debi-Lee, Yes, my problem was with the potential energy required for grinding processes, plus wear and tear and replacement of parts, vibration and platform...
Some things like pressurized containers needed to do melting and chemical processing, and heated systems are much more practical when larger. Tiny movers might...
Thanks Debi-Lee, CVMR deposition is slow? I don't think this is vacuum deposition. Do you have any data about speeds of CVMR deposition and the factors that...
Actually Jan, I believe salvaging debris is going to be much more important than grinding it up and smelting it. I see in my minds eye some guys floating...
Well, I think that so much of the salvage will be just fragmented debris, Ueli, that picking over the bits may be too labour-intensive. This ties up the most...
Just off the cuff Jan: - The most important debris to be taken out with priority will be the large chunks, not the small bits. And most of those large chunks...
More thoughts on this, Ueli........... Must admit I am deeply prejudiced about the reliability of reused second-hand machinery, especially where lives may...
... centrifugally ... ==>First problem I have with "heating" plastics is that it's never a harmless process. Any kind of recycling does damage the material....
Just had a brainwave thinking about the economic parameters: Actually, junk as shielding material costs too: It costs the water the tug needs to throw out its...
Tricky one this, Ueli. The junk has already cost $10000/Kg to place in orbit, so each kilogram is worth at least this plus the cost of water. However, if bulk...
Hi "El_Slapper", Hey, we don't yet even know your proper name. Could you introduce yourself? But anyway, welcome on board. Good to have a french speaker on...
Yes this is tricky. I was just thinking that if we have to send up 100kg of water into orbit for a tug to tank in order to chase up and haul in a 50kg piece of...
... yourself? ==>Romuald Louvrier, 32 years old, former plastics engineer(specialized in forming, not in chemistry); today working in computing for insurance...
