A new passive cooling system relies on evaporation and radiation and requires no electricity. The device can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient ...

With rising temperatures, humans have become more reliant on cooling technology to maintain stable temperatures. As a result, buildings are using more energy to cool, and urban areas are particularly ...

Passive cooling refers to technologies or design features that lower the temperature in spaces without the need for power consumption. The strategy uses free, renewable sources of energy (wind and sun ...

Finding appropriate methods of cooling electronics allows engineers, designers and other professionals to prioritize sustainability by finding solutions that will make the products last longer and ...

Passive day cooling is a promising technology for the sustainable reduction of energy consumption. Researchers have now created a test system with which the materials used for passive cooling can be ...

Engineers at Duke University have demonstrated a dual-mode heating and cooling device for building climate control that, if widely deployed in the U.S., could cut HVAC energy use by nearly 20%. The ...

A simple cooling system driven by the capture of passive solar energy could provide low-cost food refrigeration and living space cooling for impoverished communities with no access to the electricity ...

As the world gets warmer, the use of power-hungry air conditioning systems is projected to increase significantly, putting a strain on existing power grids and bypassing many locations with little or ...
