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 ...

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 ...

A shipping container that can test passive cooling systems could help researchers and builders find carbon-free ways to keep people cool in extreme temperatures. Researchers created the 60 square-foot ...

In 2018 Cape Town, South Africa came frighteningly close to being the world’s first major city to run out of water. Unfortunately it’s not alone; water scarcity is a growing problem in multiple ...

An international research team has built a cooling tech consisting of heat absorber pipes that are thermally connected to the PV module, heat releaser pipes that exchange heat with the water body, a ...
