MIT scientists have created a new passive cooling tech that could revolutionize how we keep things cold. The tech relies on a three-layer design that includes a solar reflector, an evaporator plus emitter, and insulation. It only requires water, and researchers have used it to cool ambient temperatures by up to 19 degrees Fahrenheit. In humid conditions, the device may allow food to be stored for up to 40 percent longer than without it. MIT scientists say the tech could open new doors to storing food and other items that require being kept at lower temperatures.Read Long Article
