This is just one of many posts that come to the same conclusion about the financial viability of a venture to mine (you wouldn't bring the whole thing back) that asteriod. I think it's a bit short sighted to assume that you would want to bring that stuff back to earth so that you could sell it on the open market. Hell, it's damn expensive to get that stuff up there in the first place, both in terms of energy and money. There are some things that can only be manufactured in microgravity, but in any manufacturing process you need raw materials - it's nice to know there's lots up there, not too far away. If anyone is seriously considering going out to fetch it, "Have I got a solar sail for you!" :-) It's the perfect thing, it's smart (semi-automatic, adaptive control), never needs refueling, will shuttle back and forth from the asteriod in practical time frames, and if you're serious, we can have one ready for you in two to three years (or less - best estimates are ten weeks to actually build one, but the design is still underway). "Guess what?", I'm not kidding. Oh yes, the price, say $40M for the first one, much less for subsequent ones (but that's just a rough guess on my part, you can't hold me to it because I'm not in charge - I'm just working on the structural dynamics of the beast - the powers that be probably want to make a profit, besides, I'm just posting for fun - this is not an ad). Of course, that price is without launch. Cheers, Davin -- .oO tuohtiw esoht fo noitanigami eht ot gnihton evael Oo.
