the waste heat comes from cryogenics system that keeps all of this helium at below 3K. turns out you need to spend a lot of energy to cool down things to temperatures this low

there’s nothing wrong with 3rd party batteries, if it’s worn down so badly that it no longer does the thing that it is supposed to then replace it, idk why it’s a question. I replace mine when they’re at 60% of original capacity

Your best bet is to just not engage with them when topics like that come up

real soon it will include any topic

if sun was orange, it wouldn’t be orange, it would be just precieved as regular white light, and new-orange would be even more oranger than what we know today

you can’t turn a gas into liquid by compression alone if temperature is above critical point, you also need to cool it down. separation is done by fractional distillation, but the reason it’s done is mostly about oxygen (medical and steelmaking among some other uses). for nitrogen it’s somewhere about -150C. first air is stripped of water and carbon dioxide, then it’s turned into a liquid, then it’s separated into oxygen, nitrogen and argon, and some large specialized plants also separate xenon, krypton and neon

if you don’t actually care for it being a liquid, there’s another method called pressure swing adsorption that separates gases based on how tightly do they bind to porous surfaces under pressure. this is how medical oxygen concentrators work

making liquid nitrogen is pretty efficient these days, as in not much more energy is used than is actually needed

if everything else fails add matrix account to your profile (to have another communication option) and reach out to admin of your instance

that’s at least four days before kidnapping of maduro

op what else did you knew

dune (1965) was written 26 years before desert storm (1991) and before iran-iraq war (1980) or iranian revolution (1979) or six day war (1967) or black september (1970) or yom kippur war (1973) but just after baathists took power in both syria and iraq (1963) and some time after coup in iran (1953), suez crisis (1956) and nasser taking power in egypt (1952)

some context for the bottom row https://www.aljazeera.com/news/2025/12/16/exiled-russian-accused-of-spying-on-opposition-including-navalny-movement https://novayagazeta.eu/articles/2025/11/04/russian-pro-democracy-activist-detained-in-poland-admits-to-working-for-fsb-en-news

tldr openrussia didn’t learn that there’s no such thing as former fsb agent, and now there are consequences

dude, people join irl face to face cults, of course they do

as i understand, this is what bellingcat uses as a major source of data when reporting on russian activities

“It is one of the paradoxes of modern Russia: on the one hand, these services are illegal and rely on leaked data, yet on the other, they are far more convenient for day-to-day police work than the multitude of official departmental databases,”

gaben on piracy: “We think there is a fundamental misconception about piracy. Piracy is almost always a service problem and not a pricing problem,”

There is a thermal energy storage included as s major part. This works because compressing CO2 to 55atm adiabatically heats it up to some 450-ish C, so that heat is pretty high grade, and only the final stage cools it down with heat exchanger open to air. In discharging direction, some heat is taken from outside air to evaporate part of CO2 and heat stored is used up

compressors, turbines (like steam turbines), piping, some of which heat-resistant (500C), container for liquid carbon dioxide, lots of plastic for the bubble, something for thermal storage, dry and clean carbon dioxide, these aren’t unusual or restricted resources, don’t depend on critical raw materials or anything like that

Compressed air without heat recovery is more like 30%, so this is huge

Carbon dioxide can be liquefied relatively easily which is what i guess makes this efficient

wood, magnesium, aluminum, plastics, they say titanium is bad, but i’d expect iron, nickel, manganese, tungsten, silver, maybe zinc to be worse

in this economy?

apparently ww1 era british soldiers figured out that cordite works like amyl but shittier (more specifically, nitroglycerin part) https://pdfs.semanticscholar.org/abaf/009c8713aadd8accbb03b2b40a93b5c3c77a.pdf

smokeless powder is, sort of https://en.wikipedia.org/wiki/Nitroglycerin#Industrial_exposure

it’s hacky and wrong. or you could use different hardware, maybe from competition, because result isn’t worth electricity it used
