      Oh hey, my alma mater. Seems kinda weird anything cryogenic could be “unplugged,” since there’s a fuckoff-massive tank for liquid nitrogen outside the Low building… the tallest building on campus. Though I’m pretty sure it pipes over to Walker Laboratory, a thousand feet away and a hundred feet lower. Neither building being the Ricketts lecture hall and nameless gymnasium shown in the video thumbnail. When was that picture even taken? I think '86 Field is all crisscrossed with desire paths now.

        The article explains it. The freezer was wired through a disconnect box that was locked to prevent anyone from turning it off, but the janitor found the circuit panel and turned off the circuit breaker.

          … yeah, and it’s kinda weird circuits were involved, when we have a mad-science supply of liquid nitrogen. I would have assumed that was the mechanism for keeping anything extremely frozen for decades on end.

              That is a bit over my head (my degree is in CompSci), but the research samples only had a 3C degree margin for error (77 to 83C) so I am assuming they had a good reason for using the setup that they had. Or maybe they were forced to accept that setup due to financial limitations.

              Either way, privatization was 100% at fault here. The university wanted to cut costs (avoid paying benefits) so they outsourced the cleaning job to a private company who hired the cheapest guy they could. The outsourced company didn’t understand or respect their research and the guy they hired obviously didn’t either.

            If you find a reliable cryonics group, that’s exactly what they do. Alcor, for example, stores bodies upside down in tanks of liquid nitrogen so that if the power and backup power go out, it will still take a lot of time before the corpses defrost down to the head.

    Yep, that’s the fun part of this whole cryogenic thing. In order for your body to make it into the 25th century or whatever, it needs to be continuously frozen for multiple centuries.
    No defects, no prolonged power outages, no human errors, no your great-great-great-grandchildren deciding they don’t want to pay for keeping a guy frozen they never met.

    And even if your frozen body somehow makes it to the 25th century and they actually have the technology to restore your freeze-damaged body, you still need whoever’s alive then, to care to actually do that thing…

        The unmitigated radiation outside the ionosphere would also do just as much if not more damage over time than freezing.

        In space you need even more cooling, unless you put them on the dark side of the Moon or somehow keep maintaining an orbit that’s always in shadow.

          Make sure things are good and cold first, then just send into an orbit around the sun that’s at a Lagrange point far enough out to stay cool.

          The dark side of the moon still gets just as much light as the other side so not sure why you mentioned that one, but you’re right it can be hard to get rid of heat in space if you’re producing it.

            You are right, not sure why I said “dark side”, I was thinking of craters that are in permanent shadow (a bunch of those on poles).

      freeze-damaged body

      Well that part is easy! Just run 'em through the vaccuum sealer real fast and you won’t have any freezer burn!

      1. They store the bodies upside down in tanks of liquid nitrogen so that if power and backup power go offline they still have a while before the nitrogen boils off.
      2. Assuming revival becomes possible, it will likely decrease in expense and difficulty as time goes on. It seems likely that at some point people would be woken up just out of curiosity or for a study, once it becomes cheap enough.

      And still it is infinitely more plausible at a success than anything else…

        Making your peace with the fact that you are mortal probably still has the highest success rate.

          You need to do that either way, cryonics has the goal of extending your life, not make you immortal, obviously. Even if somehow the tech works out, you are still going to die at some point, probably in a traffic accident.

    Time for my funny story!

    At my University, the CIS department had a bunch of really expensive SGI servers (Origin 2000’s) together in a server room that was kept at some chilly temp, 50° or 60° or something (nothing crazy). One weekend the power went out, and while the CIS department had battery backup for the machines, facilities didn’t have battery backup for the A/C. They said, afterward, that the temperature in the room climbed by 200°F within a dozen minutes, and all of the SGIs crashed. The hard drives in those were designed to be spun up exactly once - the machines, once powered up, were never powered down - and the abrupt shut down ruined all the disks. I don’t know what it cost to replace them, but it was a minor financial scandal.

    I loved SGI at the time. SGI shipped that model in these giant, 8’x4’x4’ crates, on which they printed “TERMINATOR - THIS SIDE UP ⬆️”, which in the 90’s was hilarious.

    A bonus, related power outage story: once a friend of our’s was working on her graduate thesis; she was a graphics artist, so it was a CGI animation she’d build on a NeXTSTEP desktop. A few days before submission, some drunk ran his pickup truck into a power line pole in the middle of the night and killed the power in the off-campus housing where she lived and was currently working on her almost-complete program. The surge wiped her project - again, mid-90’s, disk was expensive, tape was even more expensive, and few people did backups regularly. She was set back several months and had to submit a really early version of the film. That wasn’t a funny story; it was a traumatic experience for her, and we all felt terrible about it.

    Those really were some wild-west days, though, and there was some seriously sexy, entirely unaffordable, hardware out there, before everything went beige. NeXTSTEP and SGI workstations were the pinnacle of style, but even Sun offerings had some pizzaz. It wasn’t until Jobs came back to Apple that computers started getting style again.

      Sgi boxes were the shit, but they came with a crazy price tag. A friend bought their smallest one (indy I think) which was still quite fun even though it soon felt quite crippled compared to a basic pc with Linux.

      Unrelated story, I managed to save an early model (iris 3020 iirc) from the trash and found a home for it in a technology museum. So that was nice.

      Frankly whoever proposed a hard drive that couldn’t power down should’ve been backhanded by everyone in the room. Themselves included. Whatever team shipped that immediately evident error should’ve been fired. Not even “out of a cannon, into the sun.” Just regular told to pack their shit.

        I may have misrepresented it: they may have been able to be parked, but that required a controlled shutdown - not a sudden hardware failure. And these were supercomputers, before cheap commodity hardware took over server rooms. It was common that these would be turned on and almost never be shut off except when being replaced.

        Lots of hard drives required parking and would risk running the drive if the heads weren’t parked before being spun down. The design required the later of air from the spinning disks to float the heads over the disks - if you didn’t park the heads before spinning them down, the heads would touch down on the disks, sometimes while there were still spinning, and scratch the surface and ruin the disk.

      A well insulated freezer that never opens would use very little power once it’s already cooled. The impressive bit of this comic would be large thin pieces of glass providing enough insulation.

      Maybe it’s super efficient insulating material and the electricity is only needed to maintain the temperature.
