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.
The freezer in Futurama didn't need any special shit. This is false.
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
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.
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.
aaaah but you are an expert it seems? where did your expertise come from? genuine query.
would love to see evidence of this.
Do you think you're reading a serious comment?
I never underestimate the ignorance of my fellow man.
sure thing bike powered cryoguy lol
this is obvious. you just do not get it, at all. still waiting to see that bike.
per what? hour, day, week?
and your bike stuff - oh well no they don't have bikes at the facilities that was all bunk lol
you simply aren't credible mate. I've never posited that they require a power plant. But they do require power, and it's not exactly insignificant for any facility holding more than a few dewars.
RE: Thermodynamics, your original statement said that they didn't require cooling or input - and that's false. Sure you can get liquid nitrogen delivered from offsite - but what did it take to make it, transport it, and pump it around? Offsite doesn't mean it's free. It's gotta be condensed somewhere. Pressure swing adsorption isn't free. You can't put out a bucket and wait for nitrogen to condense. You simply moved the requirement from 'gotta make it' to 'gotta pay someone to make it and deliver it'. Which actually makes it's impact larger. Creating it, moving it around, pumping it - all require - what's that?
POWER.
Such a silly silly 'debate'. So petty and insulting, while certain you're an expert because....? lmgtf eyeballs and pemdas didn't do you much good here.
Have a great day.
that's got to be at least per dewar / container. you're not going to keep an entire facility going on 100w.
bullshit. there's going to be boiling even in a vacuum dewar; hell the moment you first fill it that load of cold liquid has to bring down the wall temps, causing some of it to boil.
it will have to be replaced eventually. and you're entirely ignoring the fact that the nitrogen delivery is an tremendous cost in power, it's simply occurring off site so you're not counting it? pfft
so neither of us is a subject matter expert, but I'm not trying to sell you some kind of pie-in-the-sky 'just top off the nitrogen and it'll be fine' line of bullshit.
as 99% of the people downvoted, perhaps maybe, just maybe, the way you're expressing your views isn't being read the way you're intending. now, not saying you're wrong, but perhaps with those kinds of numbers you'd be better off looking at what you wrote and revising that instead of silly stories about bicycle power and mythical efficiency.
and still, even if the nitrogen is delivered, internalize it does cost to be made. THERE IS NO SUCH THING AS A FREE LUNCH.
Even liquid nitrogen in a vacuum dewar will boil off a minute amount, which over time has to be replaced by new liquid nitrogen, which isn't FREE TO MAKE.
you're so fucking wrong and so oblivious I don't see any point in continuing the dialogue. good day.
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.
