At lunch at #AIAASpace2013, NASA is proposing ten tons of it for propellant for the asteroid mission. World production is about a ton per year.

Fred Pohl
Rest in peace.
He wrote great fiction, but his economics was short sighted.
In general, SF writers aren’t that great at economics — (too) many of them are, after all, leftists, particularly the New Wave types. Heinlein was one of the few who generally got it right.
The STEM “Crisis”
“If there was really a STEM labor market crisis, you’d be seeing very different behaviors from companies,” notes Ron Hira, an associate professor of public policy at the Rochester Institute of Technology, in New York state. “You wouldn’t see companies cutting their retirement contributions, or hiring new workers and giving them worse benefits packages. Instead you would see signing bonuses, you’d see wage increases. You would see these companies really training their incumbent workers.”
“None of those things are observable,” Hira says. “In fact, they’re operating in the opposite way.”
And even if there was, the notion that NASA would help it is ludicrous. Particularly if anyone thinks it’s going to do so by building rockets to nowhere.
Happy Marx Day
So why do we have a Labor Day anyway? What is it about “labor” that deserves a day off (isn’t that ironic) and a three-day weekend, but not (say) Entrepreneurs Day, or “People Who Have To Meet A Payroll” Day?
I know, I know, it was a reaction to some of the brutal labor practices and strikes of the later nineteenth century, particularly Pullman. But as Detroit exemplifies, we went too far in glorifying labor, and we don’t seem to care enough about the people who actually create the jobs, to the point of abuse. It’s not surprising that, in the wake of ridiculous overregulation (capped by ObamaCare) they’re going on strike, and we’re becoming a part-time nation, at best.
Water On The Moon
The Robot Revolution
Ignoring our fiscal issues, this is one of the biggest problems our society will face in the coming decades, I think.
[Update a while later]
This seems related, somehow: The ugly side of open borders. I agree with Mickey that charity and shaming are not the solution to hard-working but unskilled people.
Light Posting
I’ve been busy doing final editing on the book (it’s amazing the problems you see when you actually print a proof copy), and getting ready for a combination business/pleasure trip to Alaska (I leave tomorrow morning, and won’t be back until the evening of September 4th). But I’ve also had problems logging in to WordPress (it times out). It’s not a server problem — I can ssh into it, and the blog itself seems to load properly and people seem to be able to comment. I’ve heard that there are some brute-force password attacks occurring to WordPress logins, so that may be the problem. Anyway, I’ll put up a couple posts right now, because I seem to be able to (at least momentarily) get in.

Has China launched one?
Reusable Rockets
Megan Gannon has another article on this past weekend’s DC-X meeting in Alamagordo.
