Seriously?
I just can't see mining a trillion tons of anything to carry it back to earth being a good idea. And mining a moon seems fraught with peril, an generally a bad idea. For Christ sake if exhaling can destroy earth's environment, how could de-orbiting a trillion tons do the planet any good?
The only way to gain the riches of mars is to live there. You can't bring it home.
He-3 fuses *without* flooding the surroundings with high-energy neutrons which embrittle the containment and induce radioactivity. There's oodles of it on Luna, for sure, and likely also on Phobos and Deimos. At four megabucks per kilo, we could stand to bring back as much as we could mine.

Well, this is a good opportunity to invite your neighbors into your radio shack to listen to the ham traffic out of Haiti.
Some would not come in because they're afraid the dangerous electromagnetic radiation will cause them to spawn three-headed babies. Meanwhile, they park their butts 3' from what's essentially a 25,000 volt x-ray machine (CRT in a TV) so they can watch their shows, while hams are out in the cold and dark practicing for when we're needed.

Put a ring of reflectors on the outer periphery, and watch the output from the satellite with multiple systems. If any of the observation systems fails, unfocus the beam immediately (quicker than a safe shutdown), so no one point on the ground gets any more radiation than 50% of normal sunshine.
All that was worked out by O'Neill in the 80's. Old news.

Baen Books at webscription.net sells a five-pack or six-pack of e-books for $15 every month.
They also have over six dozen free e-books, contemporary, in print, at baen.com/library .
Furthermore, they sell *without* DRM, in multiple formats, and if you change devices later, you can download your purchases in your new preferred format.
Ditto. I bought my first e-book from Baen.com in 1998 to read on a Palm VII (monochrome); since then, I've used a VIIx, i705, T3, T5, TX, Nokia 9300, 9300i and E90 smartphones, plus about a dozen laptops with Win 2K-XP-Vista-7 and Ubuntu Hardy-Intrepid-Jaunty-Karmic. Baen made it easy with the Baen Free Library; the first six dozen e-books, are free, little boy (he he he).
Maybeso a Nook be better, but I *always* have my smartphone with me, and spending $500 on a reader equates to buying 105 e-books.
Plus, e-books have probably saved me from scoliosis, as I no longer have to carry a dead tree book in my hip pocket to have something to read wherever I am.
And, what is this DRM of which you speak? Baen doesn't cripple its e-books, and every time I change platforms, I can redownload my e-library in the new format. For free.
The debate has been ranging here in Norway lately, since we hold a lot of the world's known reserves of the stuff (as opposed to many wild guesswork assumptions about possible reserves around the world). The reason why not more reactors are built is quite simply because the technology is not there yet. By most accounts, a functional prototype reactor is 20 years away.
It is a very complicated technology, and more difficult to engineer safely than uranium reactors that we currently know a lot about. Several studies, for instance from MIT, cast doubt on whether thorium reactors will even be cost effective. Extracting thorium from the ground is harder than for uranium, and the enrichment process is more difficult and costly.
Enrichment? Bull-pucky. All you need is garden-variety thorium, no discrimination between isotopes is required. The same stuff that's been in Coleman lantern mantles for decades works just dandy. And, to improve the cold startup issue, add a Farnsworth Fusor (yeah, Philo T. Farnsworth, the inventory of practical TV) to generate neutrons cheaply from deuterium, neutrons to speed up startup.
Thorium will also produce dangerous, radioactive by products,
and if you have enrichment capabilities for thorium, it is not a far step further to produce weaponized plutonium.
Straw man. No enrichment is required.
Chuck Hansen's THE SWORDS OF ARMAGEDDON is just one instructive source I've read on atomics. Better to light your lamps with nuke power than to curse the darkness, eh?
2) There seems to be only one company in the whole world that can build a reactor containment vessel in a single piece (to reduce risk of radiation leaks), and it's already build at max capacity (four per year). http://www.bloomberg.com/apps/news?pid=20601109&sid=aaVMzCTMz3ms
So? Molten salt thorium reactors are not giant 'splosive teakettles. A site-welded containment would be just dandy, since they don't run at dozens of atmospheres of pressure. They run at local atmospheric pressure, or even below that, which is just one of the inherent safety features that BWRs and PWRs don't have.
BWRs and PWRs evolved from USN designs made to fit into a small hull, sacrificing safety for compactness. We can redo it right, with molten salt thorium reactors which will slow down if overheated, as a part of their basic design.
3) After spending lots of money, resources and time on building reactors and the super expensive tools to build the parts to build them, and you hit "Peak Uranium" within 100 years, it might not be really worth it. Might be better to look for something else to bet big on.
Umm... did you forget to read the headline of this article. We're talking *Thorium* here, many times more plentiful than Uranium to begin with, and that was before we started using up Uranium to make Plutonium. This also puts paid to the specious straw man argument of your first point.

Thorium will also produce dangerous, radioactive by products,
"The high reactivity of fluorine traps most fission reaction byproducts."
Which you keep in the reactor and burn up, for unlike Generation I-III reactors, you can keep using thorium fuel in a molten salt reactor far longer than in a uranium-fueled PWR or BWR and thereby burn off the high-level fission daughter products, extracting much more power from the fuel and simultaneously greatly reducing waste to be stored. "The bulk of the fission product elements remained stable in the salt. Additions of uranium and plutonium to the salt during operation were quick and uneventful, and recovery of uranium by fluorination was efficient."
and if you have enrichment capabilities for thorium, it is not a far step further to produce weaponized plutonium.
Straw man. No enrichment is required.
