  • The 2021 world’s whitest paint, for which Ruan was entered into the Guinness World Records, had to be applied at a layer of 400 microns thick, which is only possible for robust and stationary objects like buildings.

    For things like airplanes, cars, or anything that comes with weight restrictions, 400 microns is too dense a coating to be useable.

    Anyone able to put into perspective how 400 microns vs 150 microns matters that much? I understand that extra weight when sending things to space is expensive but how does it compare to say smuggling a gorilla costume aboard the ISS, flame decals or other stuff people put on their cars, or whatever other examples (preferably better than my examples at least) that makes 400 microns too dense?


  • I know there is something like a “Rule of Three” when it comes to backups where the rules seem to differ, but one of the rules usually mentions off-site backups. The scenario usually talks about an unexpected fire destroying everything in the home, but recently with Hurricane Ian in Florida for example, the entire region could be flooded so even storing a backup at a nearby friend or relative’s place might not be sufficient.

    In a case like that, I wonder if having a water/fireproof safe would be good enough if cloud storage is not an option. It seems most waterproof safes are water resistant for up to 72 hours, but it might be better instead to just disconnect and take the backups with you if you need to evacuate and have time.
