take any aluminum can, cut it open, cut a plate fitting in your wallet, insert it there so that it sits on external surface if your walket, done, that's your yeehaw rfid blocking sleeve, extra mass 1g
if you want to scan bus pass you can put that card on external side of it
They could state it's Saudi right in the title
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
it's easier for dear leader to blame americans for any and all problems (not an exaggeration, first example i found https://www.upi.com/Top_News/Special/2009/11/02/Irans-IRGC-blames-US-for-problems/32571257206055/ it was stated on iranian state media verbatim recently, i'll add it when i find it) than to accept responsibility for their oppression, corruption and inefficient governance.
yeah mate nixon personally descended from heli to brainwash khomeini into making basij a thing. every irgc grifter is a mossad agent actually. i bet that cia shat their pants too
Fuck this clickbait title. It's no secret that no tears will be shed in Riyadh if something would happen to islamic republic leadership, and Saudis made this known recently https://www.axios.com/2026/01/31/saudi-us-strike-iran-kbs-trump
if you believed that "no saudi land or airspace will be used to attack Iran" was genuine i have a brigde to sell you
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
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
it's a type of heat engine. heat engines require temperature difference to work, and the lower it becomes, the less energy is there in the first place and a very fundamental limitation, that is carnot cycle efficiency, goes down very quickly. in practice, all heat exchangers have some thermal resistance, and the lower temperature gradient you can afford to use up on this, the bigger heat exchanger becomes, making low grade heat powerplants extremely big and expensive on top of barely generating any electricity
i don't think there's a lot of energy to be squeezed from daily variations in air temperature vs lake temperature, you'd be better off just by using solar panels on the same area
