Novel coating to keep buildings cool without air-conditioning

Air-conditioning can account for more than 40% of the domestic energy consumption, and contributes to greenhouse emissions by making use of chemical refrigerants such as chlorofluorocarbons and halogenated chlorofluorocarbons. Global temperatures, however, keep rising, and the situation becomes more unbearable in the presence of humidity. At 80% relative humidity, temperatures …

Recently Discovered Nanocoating Makes Heat Transfer Happen Much Easier

The action of cooling things down plays a critical part of any mechanical or electric system, because the inevitable heat, produced by friction, is the number one cause of almost instant failure. So far, different methods that cool systems have been discovered, but not to the extent of performance that engineers dream of building their computers or mechanical devices (cars, for example).
