zeroth of all, they were figureheads in large organizations. luigi has none of that
besides, there’s no improvement without criticism
- Comment on Che Mangione 3 weeks ago:
Luigi is a rich libertarian techbro bordering on AI cultist. he likes Thiel and Musk, he thinks that human immortality is feasible, that AI will outsmart us all real soon, and bought in in a bunch of other tpot/longtermist/ea horseshit hook line and sinker. he also only started caring about state of healthcare industry when it touched him personally. he’s not leftist in any useful meaning of this word
this is his twitter xcancel.com/PepMangione these are his takes: xcancel.com/PepMangione/…/1780863519677940189#m xcancel.com/PepMangione/…/1750041444239434013#m xcancel.com/PepMangione/…/1600875886727016449#m this one is pinned tweet

if you looked up temperatures needed for aluminum electrolysis,
and then you have to deliver electricity to it, keep it isolated electrically, thermally, chemically (kept sealed), and how do you even make plastics without steel reactors

- Comment on Mass Destruction 1 month ago:
teller also wanted to make it a salted bomb but this is nonsense and not how neutrons work at these energies
- Comment on Mass Destruction 1 month ago:
100x (1.5Mt range) was done and still fielded (1.2Mt, B83), but teller wanted to make 1000000x bigger one (10 gigaton range). it was based on a flawed understanding of several things in thermonuclear weapons but teller never let it go. the bit that worked was done by somebody else (stanisław ulam)

- Comment on 10 Ways to Destroy the World 1 month ago:
2 means “just” removing earth’s magnetic field, van allen belts don’t shield from anything, these are trapped solar wind
5 could have side effect of disturbing ozone layer, on top of, yknow, just suffocating every animal
7 is not even wrong
10 sounds like CIA’s final plan for assassinating Castro: just let him die of old age
- Comment on Know thy enemy 1 month ago:
you’re probably talking about direct reduced iron and it’s really a problem that can be dealt with easily, just chuck a piece of coke when it’s molten for the second time in electric arc furnace (and maybe electrodes introduce enough carbon)
maybe there’s a way to make electrowinning iron economical, and it’d be pretty green too, but i don’t know if it is workable
- Comment on Know thy enemy 1 month ago:
coal can be substituted to some degree with processes like direct reduction. hydrogen works but syngas from biomass or trash also works
- Comment on Know thy enemy 1 month ago:
not now, but if hydrogen were to be used as an energy source/storage, then it’d be used plenty. same with batteries

- Comment on Know thy enemy 1 month ago:
ikr, but that tweet implies that all of oil/gas/coal ships would be unnecessary
- Comment on Know thy enemy 1 month ago:
this is arguably fine, because this way ships make clouds of sulfate aerosols, which have slight cooling effect and no one is bothered by it when it’s released over sea
- Comment on Know thy enemy 1 month ago:
Some of these ships would carry green hydrogen and new lithium batteries and old lithium batteries (to be recycled) and whatnot. Also at least some oil would be still needed for fine chemicals like meds or (idk what’s proper english term for that) large scale organic synthesis like plastics, or even straight distillates like hexane (for edible oil extraction) or lubricants. Some of usual non-energy uses of oil can be easily substituted with enough energy like with nitrogen fertilizers but some can’t

- Comment on How can we get to Mars faster 2 months ago:
what neutrons? we’re talking about shielding of spacecraft moving out of earth’s magnetosphere, not a spacecraft travelling through core of active nuclear reactor
the kind of radiation that is relevant are high energy protons (and alphas and electrons, with a sprinkle of heavier nuclei) from sun, mostly. there’s no relevant source of neutrons
(and incidentally water is pretty good at absorbing neutrons too)
- Comment on How can we get to Mars faster 2 months ago:
water does not expand upon irradiation, what the fuck are you talking about. you can’t reflect high energy protons (what would be important in radiation in interplanetary travel) you can only either absorb them or let them pass, there’s no third option, same for anything above uv and electrons
to a first approximation (rather good one at that) (for gammas) absorption is proportional to how much mass per area unit is used as a barrier. 1 g/cm^2 of water is just as good barrier as 1 g/cm^2 of lead or steel. this means that you can absolutely use completely normal, regular potable water as a radiation shield
Water in its purest form would have to take on mass to “absorb” radiation, expanding a hull and destroying it over time.
i’m not even sure what it’s supposed to mean, unless your understanding of ionizing radiation is uncut nonsense
