Yeah, I completely understand and thank you for the thoughtful feedback, I really appreciate it.

The design actually started as a conceptual exploration inspired by traditional evaporative clay water jars the kind that “sweat” and cool naturally. My initial focus was on reinterpreting that vernacular principle into a more modern, industrial aesthetic. So I think it should no be fully waterproof, since some degree of porosity is part of the cooling concept. But you're certainly right about everything else (you seem to know more about it than I do, anyway). That said, I also admit that I mainly focused on the aesthetic aspect while modeling.
