- labawi 7y agoInteresting stuff. As for cooling, it wont take long to get even slightly dirty, negating all the cooling effects.
- ncmncm 7y agoBeing made entirely out of sugar, there must be something that can eat it, and will -- presuming indigestible lignin is in the way, in regular wood. It doesn't say anything about water resistance or absorption.
- ncmncm 7y agoOops, it does. They suggest hydrophobic surface treatment. It is interesting that it would naturally accumulate condensation in ambient light.
