    liquid nitrogen and not electricity doing the cooling

    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.

                Still don’t understand your point, if any

                this is obvious. you just do not get it, at all. still waiting to see that bike.

                    100W per person

                    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.

      Strawman. Yes, liquid nitrogen requires energy to create. Cryonics facilities do not usually generate it but instead buy it, it’s very inexpensive and the heat transfer is tiny because dewars are closer to a vacuum and liquid nitrogen is cheap. A human bicycle per person could power most Cryonics facilities indefinitely (yes they do have these on site). They have perpetual funds which the first failed Cryonics attempts did not. They do not cool refrigerant via electricity on site. I abbreviated this explanation because I thought it was obvious but apparently not. My point is the entire structure of modern Cryonics is not anything like what the article depicts, it’s a strawman talking about 50 years ago. Nobody in this thread has the slightest idea how they operate and is just a big misinformation circle jerk unfortunately with dozens of upvotes.

      No, I’m not trying to convince anyone “it works!”, literally combatting egregious misinformation including your strawman.

      I do not believe that entropy acts in reverse, but I am also highly qualified to understand that statement, I’m going to say top 1% or higher. I wouldn’t usually say it but you questioned my comprehension and I answered it with a (mostly) straight face too.

        aaaah but you are an expert it seems? where did your expertise come from? genuine query.

        A human bicycle could power most Cryonics facilities indefinitely (yes they do have these on site).

        would love to see evidence of this.

          The liquid nitrogen requirements in a dewar would be about 100W per person, which is within range of a human bike generator. https://cryonics.org/members/cryostats-for-cryogenic-storage/. There’s also pumping the vacuum, it’s within range as well. I edited my statement to say “bike per patient”, I guess you could have interpreted it as “bike per facility”. Alcor mentioned having them “just in case” but it was a while back when they had fewer members and I guess they took down most of their website. I think this is more to make a point, can’t imagine anyone doing that realistically, maybe it makes their loved ones feel better. But if it makes a strawman easier, sure, you can interpret my statement as “people will live forever because bicycle” and say “you don’t understand thermodynamics!!!”. Checkmate.

          Source: I am able to read, google and do basic math. Not sure where you read “expert” but that makes me qualified to make this statement, as would be many 6th graders. I’m also good at reflecting sarcasm, aaaah.

          The website (google) says (reading) $100/yr, assuming electricity costs $12 cents/kwh and the conversion is efficient, that’s 100 / 0.12 * 1000 / 365 / 24 = 100W (basic math). Evidence: uh, lmgtfy, eyeballs, pemdas?
