In an effort to produce mass quantities of healthier H2O, Chinese scientists have come up with a new method to change water's chemical composition. It involves making light water.
Natural water has tiny amounts of D2O molecules, deuterium and oxygen, mixed in with the dihydrogen monoxide.
A state-of-the-art facility aims to make desalination more efficient

By 2025, the United Nations reports, two out of three people on Earth will live in places without enough freshwater to drink or grow crops. One way to beat that trend is to extract water from saltwater. The most common method of doing that is reverse osmosis, an energy-intensive process. To reduce that energy burden, researchers are developing other methods to desalinate water, such as using biomimetic membranes. Some proposed desalination plants will reduce their energy needs by using energy-capture schemes or sustainable energy sources like wind power.
Thirsty Californians living in Sand City began satiating their thirst with Pacific Ocean water starting this week, following the official launch of the state's first full-scale seawater desalination plant. The city hopes to ensure that people won't notice any difference in quality or taste compared from the reservoir water that usually comes out of their taps, according to Scientific American.
The brackish water treatment plant is expected to provide up to 98 million gallons (370 million liters) of drinking water per year, and cut down on that amount of water drawn from the Carmel River and Seaside Aquifer reservoirs.
High costs, in money and energy, limit the usefulness of desalination as a way to provide drinkable water in disaster areas. However, a new method could lead to portable desalination devices simple enough to run off solar power or a battery, but powerful enough to supply a family, or even a small village, with clean water. Additionally, the new desalination device also cleanses water of biological contaminants.
