We live in an amazing time. We now have more tech in our cell phones than we used on the first moon landing, and our industry is no exception regarding innovation. For example, today we stumbled upon Emerging Objects 3D Printed Brick Cooling System.. It works through evaporation. Evaporative cooling is nothing new. In fact, it may be one of the the oldest type of human climate control outside of lighting a fire with sticks, but creating a building material that sucks moisture like a sponge and then allows air to circulate through it, thereby cooling the space is some next level thinking (based on ancient tech) that keeps environmental concerns in mind. And yeah - it's made on a 3D printer! Kudos folks!
