3D-printed porous ceramic cubes cool rooms by 12.6°F with no electricity or refrigerants

Essentially, researchers used the concept of a clay pot that is soaked in water and expanded on it. 

The science is that said clay pot will use evaporative cooling to reduce the ambient temperature. And there’s a fun little science experiment wherein you can take a bottle of soda and cover it with a wet clay pot to cool the drink over a short amount of time. 

The group looked at shapes that can more evenly disperse the evaporative effect and can make those shapes using a 3D print. 

Now there’s a use case I can rally behind.
