Stubsack: weekly thread for sneers not worth an entire post, week ending 27th April 2025
  • oppenheimer teaches all of us that even if you specifically learn arcane knowledge to devise a nazi-burning machine, you can still get fucked over by a nazi that chose to do office politics and propaganda instead

  • Trump calls piracy "Non-Tariff Cheating"
  • idk if i want agent orange to get a stroke because on one hand might just die but on the other hand the nonsense he speaks could just get more powerful

  • weirder thing is that blumenthal (american) uses british spelling, and russians (where british english was taught more commonly when it was relevant for them? i think?) used american spelling

  • ah okay, it's been a while since they were relevant

    grayzone, the: low quality disinformation source constantly praising putin and assad while downplaying their warcrimes and amplifying conspiracy theories favourable to these two. not to be confused with greyzone, a wagner group associated telegram channel

  • as in the tankies? i don't see blumenthal in there

  • Hey Lemmy! What is your most beloved and hated British slang?
  • i'm convinced that rhyming slang is just 19th century coal mine brainrot. you cannot change my mind

  • China has world’s first operational thorium nuclear reactor thanks to ‘strategic stamina’
  • These were not supposed to be breeders, but this is only due to agreements that are ignored ny now. Technical capability is there

  • China scientists develop flash memory 10,000× faster than current tech
  • This sounds like that material would be more useful in high performance radars, not as flash memory

  • White House Says It Has Tech That Can 'Manipulate Time and Space'
  • time travel (backwards) would break physics as we know it, what are you talking about lol

  • China has world’s first operational thorium nuclear reactor thanks to ‘strategic stamina’
  • These are fast reactors and operate on different principles. The coolant there is sodium and while hard to design and run, it's doable. French had similar reactor but only one and it was shut down. Nice thing about fast reactors is that these can burn even-numbered isotopes of plutonium, useless in water moderated reactor, and give fresh mostly 239Pu plutonium of good quality. weapons grade even, and IAEA doesn't like it. But who cares since nonproliferation is dead anyway?

  • Amazon ‘launched’ its AI-powered Alexa+ in February. Where is it?
  • why would they release another money-losing nonsense generator while new users rubes already bring money

  • rule
  • i mean boeing technically knows all their whistleblowers

  • China has world’s first operational thorium nuclear reactor thanks to ‘strategic stamina’
  • You absolutely can make a nuke out of thorium-derived material (first in Teapot MET, 1955, then possibly later by India). It's not widely used because plutonium is similar and in some important ways superior material

    The tradeoff in using salt as fuel/coolant is that now almost all the fission products are in soluble form, instead of nice ceramic chemically inert pellets, which makes any spill much worse, and i wouldn't say it's safer for this reason - it's different, and it's a tradeoff few thought it is worth making. We have figured out how to make PWRs not explode so it's not that big of a problem. This goes both for uranium or thorium as a fuel

    The reason Yucca Mountain is needed is that nuclear waste exists, if US reversed their policy on reprocessing maybe it wouldn't fill up so quickly. It's a matter of political will

    At least now, the chemical engineering for reprocessing fuel when reactor is on is not there. Maybe it'll get developed in this project, but this didn't happen yet. It all has to be weighed against existing alternatives, and it's possible to breed 233U in normal water-based reactors, so maybe there's a little reason to make MSRs in the first place. India has some thorium energy projects as well, but they're slowed down by lack of fissile material to bootstrap it (you can't fuel reactor using thorium only, it needs some fissile material)
