The idea of using energy from the sun to evaporate and purify water is ancient. The Greek philosopher Aristotle reportedly described such a process more than 2,000 years ago. Now, researchers are ...

Global drinking water scarcity is a severe problem for humans. Water purification consumes a large amount of fossil energy and generates secondary pollution. Solar-thermal interfacial evaporation has ...

Freshwater is essential for human life and the scarcity of freshwater is a critical issue in parts of the world today. In recent years, scientists have put great efforts into developing desalination ...

(Bloomberg) — Every year, about 1,400 gigaliters of water evaporates from dams and reservoirs across arid Australia, enough to fill Sydney Harbour three times, according to researchers at Deakin ...

The cell exhibited an open-circuit voltage of 1.1 V and was able to retain around 90% of its initial performance after 215 days of exposure to dim light at room temperature. According to its creators, ...

Access to clean water is one of the world's most pressing problems, but a team of University at Buffalo researchers has come up with a new take on an old technology that uses sunlight to purify water.

Tellurium nanoparticles can triple the evaporation rate of solar desalination and can raise the temperature of water from 29° to 85°C within 100 seconds. If the production of Tellurium nanoparticles ...

Across the world, solar power has emerged as one of the fastest-growing sources of clean energy. It is environmentally ...

Scientists at Berkeley Lab have developed a sort of “solar umbrella” which could radically reduce the amount of land needed for industrial evaporation ponds. Evaporation ponds are a cheap way to deal ...
