minus-squaretyler@programming.devlinkfedilinkEnglisharrow-up7·11 months agoSo different thickness materials can actually cool you off just from a heat transfer perspective, completely ignoring the PCM capabilities (I didn’t click your link I’m just assuming it’s his latest vid). https://www.thermal-engineering.org/what-is-critical-thickness-of-insulation-critical-radius-definition/ So wearing a thin tshirt in cold weather for example can actually be colder than wearing no shirt at all. Same in reverse. I’m wondering if this material is doing that rather than being some sort of PCM.
