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.
I’ll start with the complete bunk part. Yes, you are correct, it is unscientific. No argument there. But not really “bunk” as most cryonicists place the odds of working at 1%. Bunk implies a positive claim, that’s not very positive.
All modern Cryonics facilities use expensive pressurized dewars. Your statement is so egregiously wrong and foundational I can discard the rest. If you had a test on Cryonics facilities your grade would be an F, not a D-. Sorry. We could not agree on any further point but here’s a bit for you to read into.
Modern cryonics facilities are not large enough to need much liquid nitrogen, can you quote specific amounts in gallons per week? No, you can’t, because you totally made that sentence up or your company used less than a gallon a year. The liquid nitrogen required is cheap and miniscule and it’s covered by a perpetual fund. It’s actually small compared to other upfront costs. Perpetual funds are how the Getty Museum and Benjamin Franklin’s will operate, they have been around for hundreds of years. It’s small enough for a human powered bicycle generator to generate for a single patient (those are onsite but never used before).
It’s certainly possible for an outage but modern Cryonics facilities have seen one in decades. Can you cite proof of your statement of such a failure in the last 30 years? Probably not as it’s not true.
