if there was a way of faking presence of lower display, then you have free tv and extra screen

this is some idiocracy level shit tho

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

shooting down bosses stupid ideas is #1 productivity tip for professionals (like most people on lemmy are)

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

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

no no no no it’s on by default so it’s opt-out, and switch for that isn’t even implemented yet

in this economy?

yet another reason for installing pihole

yeah piracy community is three blocks down, fuck off

Pay no attention to the man behind the curtain

at least he didn’t cause a civil war

plenty of drone teams release geolocated videos day after they happen, but in this case i’ll guess that real sauce is classified top secret, that thing is outdated info and everyone is five steps ahead

ahem

triple the defense budget

the theoretical reason for doing that is that if you have to split jamming power over broader frequency range, then for every n^2 times increase in bandwidth, here number of channels, range decreases n times. however gnss signals are so weak, it probably doesn’t matter, and if you’re adding extra power per channel, then it doesn’t apply

now if missile detects that gnss is fucked with (signal too strong, wrong direction, physically impossible location), the correct thing to do would be to fallback to inertial navigation while accepting that accuracy decreases until gnss can be received again, if at all, and acted upon. theoretically speaking, it’s a matter of software update, better hardware also can help with that, so idk why would they release this. maybe there’s something that prevents this

can you pull ethernet cable along power cables, wherever they are?
