  • One thing to keep in mind: if someone gave you a 5.25" floppy disk with this type of data on it, even if the data was perfectly readable, would you have any way to do it? You’d need to hunt down someone whos into retro technology and hope you can figure out how to decode the information. The format itself became obsolete, so even if the data would theoretically be accessible, the means to access said data may not be.

    Point is, what are the chances that CD drives will be around in hundreds of years outside of a museum or personal collection? They’re already becoming more and more uncommon after only a couple decades. But there really isn’t a great solution to this, especially when it comes to video, because you can’t just print it out.

    Side note, are you sure that CD Golds are more durable than M-Disk?

    The glass transition temperature (the temperature where plastic starts to become malleable) of PETG is 85°C, so if you put a PETG spoon in boiling water, it would deform and become pretty useless. However, if you used a high temperature plastic with a glass transition point above 100°C, you might be able to get away with this method.

    Also, just to clarify, a dishwasher does not get to 100°C. You could use it to get the initial food off, but you would then need to boil the utensils manually on a stove to actually sterilize them.









  • That’s what I thought too, but this system doesn’t actually use salt water. It uses a membrane that’s filled with lithium bromide (a “salt” in the chemical sense of the word), which absorbs moisture from the air while the computer is off and then is able to slowly “sweat” the moisture away while the computer is running. They say it can run for about 6.5 hours before needing to be recharged.

    This is pretty cool for data centers which use massive amounts of power to keep everything cool, because it’s passive and doesn’t use any extra energy for fans or water pumps or anything. It really isn’t all that great for consumer PCs though, because it’s a lot easier to deal with waste heat.
