Adding to that, logistics are such that direct impact will be felt strongest in places like India that rely heavily on Qatari LNG to make fertilizer, but many places have other sources of both gas and fertilizer. Americas, EU, Russia and China will get by because they have their own supply and will be only affected by price increase

without synthetic nitrogen fertilizer there’s only enough reactive nitrogen going around for something like 1-1.5B people. yea mate very sustainable to retvrn to traditional farming and starve 80% of the planet in the process

there was chrome (and firefox probably?) extension that went through your all fb liked pages and unsubscribed from them (idk precise term) so that when it’s done timeline is gone entirely. fb went after its dev, removed that extension and banned him forever because it kept people off fb
- Comment on Can turkey motion machines be used for producing electricity? 3 months ago:
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 very fundamental limitation, that is carnot cycle efficiency, goes down very quickly. in practice, all heat exchangers have some thermal resistance, and the 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

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
- Comment on World's largest particle accelerator begins warming thousands of local French residents with waste energy from the 16-mile Large Hadron Collider 3 months ago:
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

- Comment on Should I replace my laptop battery, and are third-party batteries safe? 4 months ago:
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 replaced mine when they’re at 60% of original capacity
- Comment on If the color of the Sun was orange, wouldn't the clouds and everything white also be orange? My friend is adamant that 30 years ago the "real" Sun was orange but got replaced with a white LED. 4 months ago:
Your best bet is to just not engage with them when topics like that come up
real soon it will include any topic
- Comment on If the color of the Sun was orange, wouldn't the clouds and everything white also be orange? My friend is adamant that 30 years ago the "real" Sun was orange but got replaced with a white LED. 4 months ago:
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
- Comment on A new cooling technology freezes food without warming the climate 4 months ago:
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
