The second. Turns out cryo places take a ridiculous amount of energy to keep the corpses at the ‘proper’ temperature, and those running such places often cut corners, and so leave out things like backup generators. The suspension fluids also need refilling periodically, which often doesn’t happen.
Edit: if you want to read the article this post is quoting, you can find it here.
Thanks for the link, that was interesting to read. They link to a "medical report" from one of the cryprofreeze companies, about three people who were transferred from being frozen completely to just having their heads preserved (apparently this is a thing).
It contains such gems as describing said process of decapitating a corpse like this:
They go into some detaile about how the bodies reacted to being frozen for years and then warmed up again, which is interesting to read (for me at least) and shows that the technology needed to revive these souls is a long long time away (if at all)"
The only real hurdle in the revival process is the fact that we don't know how to freeze folks while preventing microcellular crystals from forming. Reviving folks after that would simply be a matter of reversing the process.
And finding a way to reverse brain death.
Isn't the real hurdle that the human body is composed of different materials that have different thermal expansion coefficients, meaning any kind of freezing or thawing will lead to cracks at all scales, even down to the molecular one?
Yeah, humans are large and it's hard to freeze the entire thing at the same time even with very cold storage. The outside of you freezes before the inside and that's problematic.
Smaller mammals like rodents have been frozen and thawed successfully while still living but they are way smaller.
Can we just make smaller humans? Would creating a homo floriensis just to send them on distant stars be a unethical?
Let's do it and they can ponder our choices when they arrive long after our death.
Wtf!? Just going to casually drop that in there?
Yeah, some caveats apply but https://en.wikipedia.org/wiki/Cryopreservation?wprov=sfla1
The freezer in Futurama didn't need any special shit. This is false.
Freezing also doesn't completely eliminate background radiation. You stop or significantly slow down chemical processes, that's it.
Yeah, they even note in the article that meat in the freezer still eventually goes bad. It’s nothing but junk science.
I guess it's not like the frozen person will hold you accountable for cutting corners.
No modern Cryonics facility fits this description. They all have perpetual funds, take no energy as it's liquid nitrogen and not electricity doing the cooling, and I've never heard of any "forgetting" to refill. Source? Actually forget it you just wrote complete bullshit lol.
that's not how thermodynamics work. do you think a cryogenic liquid stays at cryogenic temps by itself? even in a storage dewar there's heat transfer.
Do you think you're reading a serious comment?
I never underestimate the ignorance of my fellow man.
No energy? Do you understand the laws of thermodynamics?
No, they understand the future, which is better. .ayve get on board, stupid Luddite.
I’ll place my entire life’s savings on them not
You know nitrogen isnt just 'magic cold goo' in its liquid phase, right?
Who am i kidding; of course you don't!
Edit: love all these kurzwel-landian-assed 'science nerds' who read one SciFi novel in the 90s and think theyre science-knower intellectuals, but don't understand thermodynamics 101 or the refrigeration cycle or other basic shit they should have learned in high school.
I take it you didn’t bother to read the article.
What? Do you have any idea how liquid nitrogen actually works? No matter how well insulated the storage is, it is still constantly picking up ambient heat which means you need to keep supplying it with liquid nitrogen as it boils off to disapate said heat. Any big facility is going to make their own liquid nitrogen onsite because of the quantities they require. Making liquid nitrogen requires a lot of electricity. Liquid nitrogen is also expensive to store a lot of because it has no liquid state at ambient temp. That means you need refrigerated and pressurized dewars which basically nobody does, or you just fill up big insulated dewars with no active cooling and let the nitrogen perpetually boil.
If one of those facilities loses electricity then it stops making liquid nitrogen and the liquid nitrogen level in the storage tanks will begin to drop. Because of the costs associated with storing large quantities of liquid nitrogen they aren't going to store enough to last a prolonged outage. When I worked in an electronics plant our bulk tank of liquid nitrogen got filled weekly by a tanker truck and we didn't even use a fraction of the liquid nitrogen that one of these cryo facilities uses.
And that's not even talking about that fact that long term cryo preservation of large creatures like humans is complete bunk.
People who pay for cryogenic storage are simps and suckers.
