Installing solar panels along Saudi Arabia's west coast could generate enough rainwater to meet the annual needs of 5 million people

Research has found stormwater interception and infiltration is proving effective for a shady tree canopy in concrete urban environments.

Researchers developed a technology that, for the first time, allows them to harvest water 24 hours around the clock, with no energy input.

Using a unique hydrogel, scientists created a solar-driven system that successfully grows spinach by using water drawn from the air.

Study shows that the salt enhances the moisture uptake of the gel, making it suitable for water harvesting in dry regions.

Fresh water is scarce in many parts of the world and must be obtained at great expense. Communities near the ocean can desalinate sea water.

Fresh water is scarce in many parts of the world and must be obtained at great expense and doing so requires a large amount of energy.
