| Vibrating ceramic ring produces drinking water from humid air in few minutes // DesignBoom MIT researchers developed a system that uses a vibrating ceramic ring to produce clean drinking water from humid air in several minutes. “There are already existing designs of the same kind, but they rely on heat from the sun to evaporate water from the materials and condense it into droplets, so this step can take hours or even days. With the one developed by the researchers at MIT, clean water-making can take a few minutes versus the tens of minutes or hours required by thermal designs. In their system, the engineers use ultrasonic waves to shake the water out of the material that can absorb moisture from the air.” |
