Scientists from India's PSG College of Technology have developed a passive solar module cooling technology that utilizes a hygroscopic salt to harvest atmospheric water from the air. “The objective is ...

A British-Egyptian research group has tested the use of hydrogels beads for PV module cooling. The micro-sized particles were saturated with aluminium oxide (Al2O3) water-based nanofluids and placed ...

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 ...

Owing to various factors such as global warming, growing population, as well as rapid industrialization, cooling has grown increasingly essential to human life throughout the years. A variety of home, ...

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 ...

Since ancient times, people have found ways to use the sun’s heat to stay warm or keep cool. They built homes from clay and other materials that hold heat well, and they placed them in ways that ...

BUFFALO, N.Y. — Passive cooling, like the shade a tree provides, has been around forever. Recently, researchers have been exploring how to turbo charge a passive cooling technique — known as radiative ...

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 ...

New materials for passive radiative cooling based on glass and ceramics are highlighted in two studies. These hard materials are more resilient and adaptable than passive radiative cooling techniques ...

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 ...
