A new solar device can turn saltwater into clean drinking water

Power plants need water to generate electricity, but electricity is also usually required to filter or desalinate water.

This reciprocal relationship — known as the water-energy nexus — means that producing one of these resources can deplete the other.

However, a group of researchers recently unveiled a device that can desalinate water and produce electricity at once by using heat from a solar panel to power the water filtration process.
