Completing our unfinished business on the moon

Nothing to worry about, you just need to get a few of these:

That would be cool, as long as they don't charge a fee. I mean, who would wanna spend a buck to see that!

Thanks for the link, very interesting stuff there.

I think they could be just laid on the lunar surface. No poles, no burying. If something happens to one, you go fix it, just like they do on Earth. You'd need a redundant array with multiple collectors and multiple sites scattered around the moon.

You're welcome. :)

Yes, Cdr. Koenig.

I think it was Jerry Pournel who said "Getting to orbit is 90% of the trip."

The moon is a pretty good first step, much easier than climbing out of the earth's gravity well to start each and every trip.

Oh, Chuck, use your imagination! The high tension lines will be on the bottom of the moon, protected from all the micro-metioites that fall upon it!

It wouldn't work on Earth, either, If you were trying to process the dirt in your backyard into Ti. You gots to go prospecting, Larry. The Moon is a whole damn world, there's places with greater concentrations of whatever you want, I suspect. (as long as it's lighter than iron) -Braz NAR 12442

Hardly - more like 30% more intense. Solar constant = 1353 Watts/m^2 on the moon and above Earth's atmosphere. You can get about 1000 Watts/m^2 at sea level on a clear day. Then your solar cells lose

Metals extraction on the moon to make space-qualified hardware won't happen for a long time, if ever. Propellants and concrete, maybe.

Actually, it was Heinlein... "Once you're in orbit, you're halfway to ANYWHERE..." :-)

Then G. Harry used it as the title of a book about SSTO/DC-X.

A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet?

Same format on ROL Chat 24/7

Last I looked this behavior is also actively encouraged over on the Baen Books forums... a publisher and editor encourageing the waste of time and bandwidth caused by rampant unconsidered, and unedited, top posting.

So? That makes it ok? Just how is web based "chat" comparable to Usenet, anyway?

My TV strolls CNN headlines horizontally, so maybe that is how we should post to Usenet. Or how about my truck takes all-terrain tires, so I should use them on all vehicles, right? Those 3 guys over there just robbed a bank, so that must be ok, too.

I like top posting here. The reason is that I've probably already read the message that that message is responding to & don't need to read it again. Also, with top posting, I don't have to scroll through the stuff I read in a previous post.

Interesting problem. On earth, high power cables are elevated and splayed out for security and air cooling of the cables. If they were buried, the heat would build up untill the cable failed. They jack up the voltage to reduce the resitance, but only to the point where losses from other mechanism become significant. On the moon, there is no atmosphere, so the cable cooling would have to be radiant, unless the heat conductivity of lunar material is much higher than that of the earth. OTOH, they could use micrwave power transmission since there is no atmosphere to attenuate it. My guess is they would just make du with local solar energy collection and local energy storage.
