This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Does this one work: https://web.archive.org/web/20230521234645/https://hvactrainingshop.com/how-a-chilled-water-system-works/
