Fresh water we can use for drinking or agriculture is only about 3 percent of the global water supply, and nearly 70 percent of that is trapped in glaciers and ice caps. So far, that was enough to ...

Drought and climate change are impacting water supplies around the world. But desalination — pulling fresh, drinkable water from saltwater— can offer some relief. Desalination technology has existed ...

Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a ...
