These moisture-sucking materials could transform air conditioning
Rather than small silica beads, Blue Frontier’s cooling technology relies on a salt solution that’s so concentrated, it can pull moisture from the air. Here’s how Blue Frontier’s cooling system works: first, a stream of air passes through a channel and over a thin layer of desiccant, which pulls moisture out of the air. Next, the now-dry air goes through an evaporative cooling step, which lowers the temperature of the air (basically the same way sweat cools your skin). In the evaporative cooling step, the air is…
