water technology

Dozens of water-harvesting pods are set to be deployed along the sea floor off the coast of California as the United States ramps up its first subsea desalination project. The effort is expected to produce 60 million gallons (227 million liters) of fresh water per day.

Water level sensors serve an important purpose in rivers, warning of floods and unsafe recreational conditions. A new one is claimed to be not only more robust and reliable than others, but also considerably less expensive.

Scientists at Berkeley Lab have developed a sort of “solar umbrella” which could radically reduce the amount of land needed for industrial evaporation ponds.
