  • Commented on Deaths and Deadlines
    I knew I was forgetting one. Another local! Helion Energy: "Magneto-Inertial", US (Washington), Funding: $30M. Apparently they want to make balls of ³He / D plasma and then make them smack into each other using magnets. This in contrast to...
  • Commented on Deaths and Deadlines
    The one I followed is known as Focus Fusion. After a small amount of very lazy searching, I dug up the following fusion startups: TAE Technologies: "FRC" magnetic confinement (aneutronic), US (California), Funding: Paul Allen etc., $800M. Commonwealth Fusion Systems:...
  • Commented on Deaths and Deadlines
    Paul Allen BUILT one. You missed the part about the skyhook. ;-) The ramjets and carrier planes and such are just window dressing....
  • Commented on Deaths and Deadlines
    In landing those lower stages, SpaceX is only doing what the DC-X did in the early 1990's, [...] Focusing on the part about SpaceX landing rockets on their tail is really missing the arguably more notable parts of their program....
  • Commented on Deaths and Deadlines
    My read on the LockMart fusion reactor is it's a tax write-down of some kind. [....] But if LockMart were clearly onto something good, I'd expect there to be competitors throwing their hats in the ring by now. Here's a...
  • Commented on Deaths and Deadlines
    Best concept I have so far is a big ass hyper-sonic air-craft as a launch platform - Go up high and fast on ram-jets, launch a smaller rocket-plane at altitude and mach-7, then have it be caught by rotating tethers...
  • Commented on Deaths and Deadlines
    You'd think that anyone who'd open up a huge container of alien code, even in a sandbox, would deserve what they got. Heck, it might even be Snow Crash. There's apparently a community of rather crazed techies out there with...
  • Commented on Deaths and Deadlines
    "...Yeah, but, like, fuck all that, pain in the arse, I mean who's gonna bother, anyway? Let's just chuck a zillion BBC Micros into space and hook 'em all up with matey's econet clustering kludge [...]" And so it was...
  • Commented on Deaths and Deadlines
    What's your take on computer 'antibodies', i.e., computers/AIs that learn how to sense self vs/ not-self and take action against not-self? In some sort of far-future science fiction world with sentient computers, weakly godlike space gods and all that? Oh...
  • Commented on Deaths and Deadlines
    This conversation about computer viruses and the speed of light is frankly kind of bizarre. I mean, seriously, if someone is building a Matrioshka Brain, I rather think they probably know a thing or two about computers already. Like, for...
  • Commented on Someone please cancel 2019 already?
    Which makes their complaints about the D's "Tax & Spend" a little hypocritical, to say the least. Their politics are entirely hypocritical and can only exist because they're based on tribalism and a compliant media. I have trouble thinking of...
  • Commented on Someone please cancel 2019 already?
    Not wanting to give any one administration a blank check Congress picks a limit which will last a few years. Or not. It's useful to keep in mind that the entire thing is nothing but an excuse for right wing...
  • Commented on Someone please cancel 2019 already?
    Well, that's the problem: the explanation for gravity is a 4D version of one of those rubber sheet models. If we're using a rubber sheet to approximate gravity (e.g. https://www.youtube.com/watch?v=MTY1Kje0yLg), bright matter is the equivalent of bbs, while dark matter...
  • Commented on Someone please cancel 2019 already?
    I have a weird question about dark matter. Since it only interacts with normal matter via gravity, can it accumulate in the centers of planets and stars? I think there are some actual physicists around here who can provide a...
  • Commented on Peak Brexit
    Thanks to those who responded to my bafflement about US voter registration. It doesn't make any more sense now, but at least I've got some idea of what the nonsense is actually saying... You really need to keep in mind...
  • Commented on Brexit! Means! Brexit!
    SFreader @ 987: [Various questions which basically amount to "how can an AI trust a hostile computer"] Your questions about AIs seem rather difficult to parse, because I don't know if you're talking about a real AI like AlphaGo or...
  • Commented on Brexit! Means! Brexit!
    How secure, actually, is AES-256 using a key consisting of 128 or more truly random bits (and proper key management)? Lots of people use it and the USG certifies it for TOP SECRET, but still I wonder... As of now,...
  • Commented on Brexit! Means! Brexit!
    Over here in the US we have some quasi racial tribes. One is descendants of the Mayflower. I'm sure that whatever lineage is necessary can be had for a very reasonable sum. After all, there's a whole cottage industry of...
  • Commented on Brexit! Means! Brexit!
    I am not convinced that race is the sole criterion, on the grounds that they regard anyone who isn't a part of their in-group (including 'Aryan' foreigners) as "One Of The Lesser Peoples". Ah, here we get to the real...
  • Commented on Brexit! Means! Brexit!
    ...this way, the USA actually gets decent football and rugby teams, and I'm sure that we can find some Rounders enthusiasts to help out with the World Series... Ridiculous! The USA already has world champion football and rugby teams. If...
  • Commented on Brexit! Means! Brexit!
    Caution: You WILL have to switch to driving on the RIGHT side of the road. Hey now, the US Virgin Islands drive on the left, this weirdly crowded version of Harry Potter Land can do it that way too. You...
  • Commented on Canned Monkeys Don't Ship Well, the Remix Version
    Not to mention solving these canned ape problems in the obvious way. :-)...
  • Commented on Canned Monkeys Don't Ship Well, the Remix Version
    One is the colonial empires that gave rise to capitalism, where colonies were meant to do stuff for the metropole [....] On the other side, we've got the rest of history, where in pure economic terms, colonization makes no sense....
  • Commented on Unsustainable Interstellar Civilization, Hotspot Colonies, and Dwarf Culture
    There's a general problem with space elevators: vibration in the tether. Here's a few more: The tether's path intersects every orbit around the planet below its tether point. This means that it's on a collision course with basically every single...
  • Commented on Unsustainable Interstellar Civilization, Hotspot Colonies, and Dwarf Culture
    What if the thing you did when you arrived at a no-longer-fallow planet was to [... have your] Von-Neuman machines scurry down the tether and build you a space-elevator? A space elevator is the sort of just on the edge...
  • Commented on Unsustainable Interstellar Civilization, Hotspot Colonies, and Dwarf Culture
    The point about oil is that we forget that it's actually both a really good energy source AND a really good feedstock for all sorts of plastics. Certainly. I was really responding to the idea of energy production... If you...
  • Commented on Unsustainable Interstellar Civilization, Hotspot Colonies, and Dwarf Culture
    I find it difficult to really take a story seriously when we combine low-tech present day energy economy (oil and gas, a few nukes) with magitech stuff like FTL. I mean, I understand that doing so is kind of the...
  • Commented on Happy 21st Century!
    The three things to look at to understand the low turnout in US elections are: While those technical reasons are all true and cynically targeted at disenfranchising selected opponents, I've yet to meet someone in my (admittedly highly biased) circle...
  • Commented on Happy 21st Century!
    Second... that's odd, I've written everything from cover letters, to resumes, to short stories, to the novel that's still sitting with an agent* - and that's about 76k words - and no one's had any problem with it saved as...
  • Commented on Not dead but dreaming
    The conversation about bank security seems kind of bizarre to me honestly. Here, I'm going to pretend I'm a bank C-level type, and we'll design our new top-of-the-line security system right now. I start with: "All right team, we have...
