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 of 32C can be perceived […]

When talking about cooling a room, people always think of air conditioners. Panasonic has recently unveiled its plans to produce an efficient spherical air blower that ejects seven times the wind it absorbs. Well, that may sound like wishful thinking, but Panasonic’s spherical air blower actually uses smart physics to do that. They called it “Q.” […]

While solar panels generate clean electricity, many of the maintenance practices are often not so clean, especially when it comes to cooling. A team from Stanford, however, claims to have found the recipe for making a new coating that allows panels to cool themselves without wasting any water or energy, while boosting their power generation. […]

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).
