Efficient Cooling: Dr Aaswath Raman
Dr Aaswath Raman of Standford University is cofounder of a startup called SkyCool Systems. They are one of several groups commercializing an energy-efficient cooling approach that takes advantage of the coldness of space, based on relatively recent advances in the ability to manipulate light at the nanoscale.
BZE Technology Radio Show: 26 May 2016: Podcast:
In 2014, Aaswath's group published a paper in Nature in which they showed that a device designed to combine the optical properties of three different materials, arranged in stack of multiple layers, cooled to nearly 5 °C below the ambient air temperature. This proved that “the cold darkness of the Universe” can be used as a renewable resource, “even during the hottest hours of the day,” wrote the researchers.
