- Comment on How would I make a HVAC simulator to see what a thermostat would do if the indoor temp was 400°F 5 days ago:
I don’t think anyone designed it to do that, becsuse 220C is like 100C above critical point of some common refrigerants (evaporation/condensation stops being a thing at this point and heat can be transferred only from hot to colder and not very efficiently)
- Comment on When synthetic dyes became available, people treated them a bit like we treated blue LEDs 10 years ago 6 days ago:
there’s indigo and another plant that grows in europe and also makes indigo but less, so you can just farm this thing, unlike purple dye that requires tons of work, and depending on period it was used by commoners (before 1200 or so, in western europe)
it’s a bit funny to look at this today, but woad (that euro indigo) trade was a big deal, it got protected by tariffs and blockades and diplomacy, and all for nothing, ultimately both woad and indigo farming was completely destroyed by synthetic indigo production. indigo wasn’t first/easiest dye to make, but it’s far from the most complex thing you can cook, even in 1900s. prussian blue is much cheaper than synthetic indigo anyway

blue leds may fuck up your circadian rhytm but won’t give you ballsack cancer (probably)
i heard it’s because leds get brighter per mA but circuits don’t get updated and leds are fed the same current as 5, 10 years ago

iirc there was a state backed bot farm on mastodon, some might have crossed over

there’s a couple of repost bots, but these are pretty obvious. you can always block them

yes LN2 is cheap-ish (about price of milk) but it’s not free. gains you’re talking about only happen when comically large dewars are used, these would have to be custom made for them - meaning nonstandard and not cheap
ah yes “just” 1nm precision scanning. even scanning at resolution of six single carbon-carbon bonds won’t help you after cell walls and everything that was inside were shredded by ice crystals formed, as i think there’s not really suitable cryoprotectant involved, if it’s even developed for human-size tissues. i don’t think it’s a thing, and also freezing rate required would be likely impossible just because of typical human size
as it stands today, moore’s law hit a wall, brain simulation is fantasy tech, and it’ll remain so for considerable time, i’d even say probably forever (humans will have more pressing issues to deal with). copy is not original and maybe it’ll be reassuring to other people, but these other people also are dead by that point so it’s useless. the rest are futurologist noises coming from people who don’t want to admit that they made a religion out of misinterpreted scifi
500 years in the future? mate, would you consider
Early attempts at cryonic preservation were made in the 1960s and early 1970s; most relied on family members to pay for the preservation and ended in failure, with all but one of the corpses cryopreserved before 1973 being thawed and disposed of.[14]
not even single one frozen today will remain so within 70, 100 years, nevermind 500

funeral home doesn’t have recurring expenses per corpse for infinite time

it’s not a gamble, it’s more of a shared belief propagated by people who took scifi way too seriously

power outages at these facilities already happened, but it’s a smaller problem in grand scheme of things. facility of this type promises to keep human meatsicle at 77K effectively forever (because magic tech to revive dead is not coming), for a single payment. this means they’ll simply run out of power/liquid nitrogen money at some point and will have to shut down, and allow everything to thaw
