Solar-Powered Desalination: Converting Seawater into Freshwater.
A team of researchers at the University of Waterloo has developed an innovative device that uses solar power to turn seawater into drinking water through evaporation.
Desalination is crucial for many coastal areas, where fresh water is scarce due to population growth and increased water consumption. Currently, desalination systems are energy-intensive and require frequent maintenance.
Inspired by how trees transport water, the researchers created a device that mimics the natural water cycle, making it efficient and low-maintenance. The device is solar-powered and can produce 20 liters of fresh water per square meter, meeting the daily water needs recommended by the World Health Organization.
The device, made of nickel foam and a conductive polymer, absorbs sunlight to convert it into heat that evaporates seawater. The salt is then removed, ensuring continuous operation. The researchers aim to test the device on a larger scale to provide sustainable water solutions for coastal communities.
This innovative technology could help address the global water crisis and contribute to achieving UN sustainable development goals.
