Scientists in Saudi Arabia have developed solar panels that absorb water vapour from ambient air. This has been used to grow spinach in the middle of the desert.
The scientists developed their method using photovoltaic solar panels and a hydrogel, which allows water to be drawn from the air for use while also generating electricity.
