Eco-Friendly Air Conditioning
A new material developed by Stanford University’s Dr. Aaswath Raman is hoping to revolutionize the way we keep cool. Made from ultra-thin layers of silicon dioxide, hafnium dioxide and silver (for reflectivity), the new material is able to radiate as much as 97% of sunlight back into the frigid vastness of outer-space while still remaining cool itself. When tested, a small wafer of the material was found to be 4.9°C cooler than its surroundings. Raman is still developing commercial applications for his new product.
