Water

The new water purification technique involves draping a sheet of carbon-dipped paper in an upside-down "V." The paper's bottom edges soak up water, while the carbon coating absorbs solar energy and transforms it into heat for evaporation.

Could This Low-Cost Device Provide Clean Drinking Water To Those In Need?

Engineers have created an upgraded solar still that uses carbon paper and the sun to purify water at an unprecedented rate
