A More Robust Solar Desalination Solution

You should drink more water. We all should drink more water, however in some places water wells are drying up and water is getting harder to get. Fortunately for us, we have a lot of ocean to drink from. Costal cities have increasingly looking towards desalination as a solution to their water problems.

Producing clean drinking water from the sea is an energy-intensive process which makes it expensive to run. Researches in Australia recently found a way to combine solar power with a new material to filter salt out of water in an incredibly efficient way.

Wang and his colleagues explain in the study that a sustainable energy source, like sunlight, would be especially useful for communities that may not have access to a reliable electric grid necessary for other methods of desalination.

“This study has successfully demonstrated that the photoresponsive [metal compounds] are a promising, energy-efficient, and sustainable adsorbent for desalination,” said Wang. “Our work provides an exciting new route for the design of functional materials for using solar energy to reduce the energy demand and improve the sustainability of water desalination.”
