These 3D printed bricks don’t look anything like an air conditioner, but that is what they are. Provided, of course, that they are wet and nature is allowed to do its thing.


The idea of ‘evaporative cooling’ goes back centuries. Now it’s seeing new life in the shape of a brick; the 3-D printed ‘Cool Brick’.


Cool Bricks act like little air conditioners without the hefty electric bill. The bricks are made of a porous material that soaks up water like a sponge. When hot, dry air from the outside flows through the bricks, the water evaporates, and cooler, slightly damper air flows through the inside.
