ah yes it’s reactionary to checks notes not support the righteous biggest bubble since dotcom era

you okay out there bud?

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)

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

chemically speaking, it’s completely fine to irradiate water because whatever is formed as a result of radiolysis would just most of the time form water back, with the rest becoming very weak solution of hydrogen peroxide. this is big part of the reason why water is used as a coolant in nuclear reactors

there are also specific nuances to stopping anything that is not gammas, like secondary x-rays, gammas from neutron absorption etc and this actually favours light element shields, like water or liquid hydrogen, for this kind of radiation shielding

i don’t get what you fail to understand, water doesn’t became radioactive or harmful in any other way after irradiation, and irradiation of food is routinely used for extending its shelf life

“remove” what exactly? water is not alive so it’s okay to irradiate it https://en.wikipedia.org/wiki/Food_irradiation

You might be semi-comfortably running linux mint cinnamon on these (assuming 4gb ram) with xfce you’re trading clunkiness and ancient looks for lower memory usage

no idea about the usual suspects, wifi, bt, graphics probably will require tinkering as is tradition

how low we’re talking

xubuntu is fine if your box is a potato or if you’re coming from windows vista

i’m here to remind you that for last 20ish years half of the time chemistry nobel goes to biologists, and now they doubled down on ai wankery with giving it to alphafold

CCGTs have efficiencies in the range of 60%-ish percent. bringing it up to 85% would mean that now these run almost at carnot efficiency taking adiabatic flame temperature of methane burning in air as upper and practical temperatures of heatsink (60C) as lower. this is not happening, because other cycles with lower efficiencies are used in practice

if you want to improve efficiency of power generation, just replace old junk with new kit, or better yet, build nuclear and renewables where efficiency matters less when considering emissions. you know what, damn i do think that lying box burning enough electricity to power a small country (like macedonia) could come up with this

not gonna happen, this would break thermodynamics. he made that up on the spot, he’s full of shit and he knows it

you are part of the problem

Nobody should trust LLMs with anything

ftfy

also any inputs are probably scrapped and used for training, and none of these people get GDPR

oh no, it would be so sad if all these libertarian assholes lost their livelihood in form of money laundering nerd tokens

don’t you know, it’s hate speech against corporate profits

this is not how conspiracy theories work. these start and end with need for feeling special for “having” some secret knowledge. it’s all elaborated nicely if you have an hour of unnecessary time https://www.youtube.com/watch?v=JTfhYyTuT44

easy high power generation from hydrogen would be in gas turbines, but this will have horrendous roundtrip efficiency. which is why it’d be better to soak up peak power in hydrogen and use it for non-power uses, like ammonia and then fertilizers, or direct reduced iron, or various hydrogenations in fine chemicals segment. these things take a solid chunk of energy to make. it’s net positive because it replaces gas https://en.wikipedia.org/wiki/Steam_reforming while storing hydrogen is pain it’s easier than electricity, and some intermediate can be stored too if hydrogen consumption can be surged

gas turbines are also fantastically versatile. any petroleum fraction lighter than grease, ethanol, biogas, syngas, hydrogen, ammonia, really anything that burns and can get through nozzle can be used as a fuel. if you have a carbon-neutral source of liquid fuel that can be stored, you have carbon neutral peaker plant

i thought sodium batteries need low hundreds C for ceramic electrolyte to work. i stand corrected

e: CATL made sodium-ion battery, i was thinking of sodium-sulfur battery
