Scientists have learned to desalinate water with solar energy

The problem of access to clean water is urgent for two billion people on the planet.

A team of researchers from Australia and China has developed a method to desalinate and clean salty or unpleasant water and convert it into drinking water using solar energy.

The World Health Organization estimates that about two billion people worldwide do not have access to safe drinking water.

In a study published in the journal Nature Sustainability, scientists reported that they came up with a viable solution, using solar energy rather than heat or electricity to trigger the filtration process.

Along with sunlight, another critical factor in this process is a special, incredibly porous metal-containing compound in which metal ions form a crystalline structure.

After testing this material on both natural and synthetic saltwater, scientists concluded that in 30 minutes, with the help of a kilogram of such absorbent, almost 151 liters of clean drinking water can be obtained.
