How do you know that Threads won’t inject ads as posts?
Still no reason to defederate, huh?

I don’t know about going downhill in general, but there are some that use regenerative braking (regular braking, on flat terrain) so maybe
yeah it’s replacement for google only if you don’t care if any of information received is accurate at all
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
nvidia executive called saltman a podcasting bro
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
because these end up generating most of electricity. older plants matter less specifically because these are less efficient - operating them means more fuel costs per MWh. normally, you can see new flashy plants generating all the time it’s practical, because these are more efficient, have less maintenance downtime etc and when demand grows, progressively less efficient units start generating coming from spinning reserve. the two exceptions are NPPs which are best operated at constant high power because of their neutron physics and renewables that are literal free energy so everything they do is taken in. the only place where you can improve efficiency of NPPs is in turbine, and that probably is pretty well optimized unless turbine is very old, because increasing steam temperature would mean changed conditions in reactor in way that could happen to be out of spec. we have figured out wind power pretty well, and perovskites aren’t a thing, and won’t be a thing until they become more durable, which they won’t. in all cases, upgrades would have to make sense both economically and/or in emission costs. this includes CHP and laying municipal heating grids, and good luck with that with how dysfunctional american local govts are (where probably biggest emission gains from CHP could be made)
you can redo this for other types of thermal powerplants and come to the same conclusion. if you say that saltman&co and his assemblage of lying machines can outsmart thousands of turbine engineers, you might be a shill for making other people believe that or a moron for believing that yourself
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
but does it run openwrt?
e: no it doesn’t, only one model had half-baked image made and available for download from some sketchy forum post made in 2014
