Solar desalination using solar stills presents a sustainable, low-cost method to convert saline or brackish water into potable water by harnessing solar energy. This approach utilises simple ...

Africa’s water crisis is often framed in terms of scarcity, but the continent’s coastlines and brackish aquifers tell a different story: the water is there, it is just not drinkable. Solar ...

Researchers have developed a new technology that harnesses sunlight to evaporate seawater and generate clean drinking water. Instead of relying on external electricity, the approach uses solar ...

Turning seawater into freshwater often creates a second crisis: hypersaline brine that is expensive to handle and risky to ...

HOUSTON – (May 14, 2025) – Fresh drinking water is a vital yet limited resource that will only grow scarcer over the next few years, according to the World Resources Institute. Desalination, the ...

A phase-change photothermal foam stores solar heat to sustain water evaporation after sunlight fades, producing fresh water ...

What if solving three of the world’s most pressing challenges, water scarcity, energy demand, and environmental sustainability, could be achieved with a single, innovative system? Imagine a technology ...

Drought and climate change are impacting water supplies around the world. But desalination — pulling fresh, drinkable water from saltwater— can offer some relief. Desalination technology has existed ...

A team of engineers has developed a system that could transform desalination practices, making the process more adaptable, resilient and cheaper. The new system is powered by sunlight and uses a ...
