Solar-powered desalination

A team of Chinese researchers have announced an efficient solar-powered desalination technique that directly uses the Sun’s energy to clean water instead of reverse osmosis.
Current desalination plants usually operate by two ways: distilling water by boiling or evaporating it, or using a membrane to separate salt particles from water (reverse osmosis). There has been a lot of research into improving the newer reverse osmosis method, but a paper published in
AIP Advances suggests a technique that could improve the energy efficiency of distillation.
This new technique uses a transparent container with a sloped quartz roof, filled with seawater. Floating in the seawater is a device made of a substance called titanium nitride oxide (TiNO), an insulating foam, and a specific type of paper.
