@[email protected] If you ever get a chance, you might want to try photographing the Torness AGR nuclear power station in Scotland close to sunrise or sunset. It's right on the coast (for seawater cooling), close by the A1(M) and east coast main line, and looks amazing in the right light (a 1980s-built temple of technology).

@dgerard Do not mess with HP, they have the *real* orbital weather control lasers! /s

@m @dgerard @o7___o7 @techtakes Back in 2007 I was a guest of honour at Penguicon. ESR was there and we got talking. As of 2007 he was all-in on all the insane "Eurabia" conspiracy theories and islamophobia. If you'd taken his word salad and substituted "jews" for "muslims" Julius Streicher would have hired him as a columnist in a split second. (That's when I added ESR to my list of "people I will not share a platform with".)

He was somewhat less cray-cray in 2003.

Here, have a Macintosh Centris/Performa 610!

That button on the right? It's not a floppy eject button, much to the chagrin of hordes of students during the 1990s, but an on/off power button ...

@dgerard I dunno if you've read it but one of the wellsprings of this lunacy is "The Physics of Immortality" by Frank Tipler (1997), in which an astrophysics prof tries to square the circle of cosmological expansion and the resurrection through simulation, outing himself along the way as a very conflicted Christian fundamentalist who is determined to torture relativity until he can derive Jesus ... https://archive.org/details/frank-tipler-the-physics-of-immortality/mode/1up

@froztbyte Your term of art in economics to describe this shitbaggery is "Veblen goods": https://en.wikipedia.org/wiki/Veblen_good

"a type of luxury good… for which the demand increases as the price increases, in apparent contradiction of the law of demand, resulting in an upward-sloping demand curve. The higher prices of Veblen goods may make them desirable as a status symbol in the practices of conspicuous consumption and conspicuous leisure."

@BlueMonday1984 Betcha the authors aren't getting paid industry-normal royalties (10-15% of net receipts) on those Veblen goods …

(A few of my novels have been sold as limited-run signed first editions. Typically for 50%-100% more than the normal hardcover price, so maybe 3-5% as much as this nonsense. Cost of goods for a leatherbound, gilt-trimmed luxury edition is maybe $5-10, plus 10% of the cover price for the author. So someone in the middle is making serious bank.)

@mountainriver Also of note: the Helios Airways Flight 522 disaster. (Loaded 737 crashed, everybody killed … because of a locked cockpit door: plane depressurized and pilots' oxygen failed, cabin crew—inc. a pilot—were unable to gain cockpit access in time to save the plane before it ran out of fuel and crashed.) https://en.wikipedia.org/wiki/Helios_Airways_Flight_522

@Soyweiser You're assuming the first Starship to Mars has a cargo of canned primates. Rest assured, it can't and it won't. (Also, I doubt Starship will be ready for Mars—extended duration in space, remember—in time for the 2026 launch window. Although a robot probe as a payload launched atop Starship is entirely possible in that time frame: you don't need reusability, just a bloody big payload bay and the ability to reach orbit once, which Starship achieved as of OFT-3.)

Anyway, if I was going to go mining 3He in space I'd bear in mind it's in the regolith because it's part of the solar wind and gets trapped there. Is it possible to collect it more cheaply using a really huge solar sail (with station-keeping as a side-purpose) made out of a membrane that traps it directly and can be reprocessed to outgas the stuff? That way you're not grinding up gigatons of fucking rock to extract an incredibly rare volatile.

@gerikson @techtakes Ian is a *very* good writer—but for those books he uncritically adopted the American colonialist ideologues' idea of an good reason for space colonization: and sure, his Lunar colony is a capitalist hellscape, but that's not the point. (The P + 11B aneutronic fusion pathway was already known about at the time.)

@gerikson @techtakes The thing about Lunar 3He mining is … it presupposes you can build aneutronic fusion reactors (a 3rd generation fusion reactor: not simple!). But if you can fuse 3He, you're almost certainly able to run a P + 11B reactor (which is also an aneutronic reaction), and hydrogen and boron are readily available on Earth. Thereby removing the entire incentive to strip-mine the moon at vast expense.

TLDR: Lunar 3He is a non-working economic justification for space colonization.
