Add another item to the list of things one can accomplish using graphene, the wonder material of the future: Clean drinking water. Graphene could cheaply and easily remove salt from seawater, potentially turning the oceans into a vast drinking supply for thirsty populations. With properly sized holes, graphene sheets may be able to serve as all-purpose filters.
A new type of wind turbine harvests not only electricity from the wind, but clean water from the air, by condensing humidity from even the driest climes. One prototype turbine is apparently collecting 16.3 gallons of water an hour from the desert air over Abu Dhabi, according to the company that builds it.
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.
Space station residents could soon get a new choice for drinking water beyond urine, sweat, and vapor. A water generation system which can extract water from hydrogen and carbon dioxide waste products has reached the space station, according to Aviation Week.
The Sabatier Reactor System could create as much as 2,000 pounds of water per year when it officially goes online in several months. It uses the chemical process discovered by French Nobel laureate and chemist Paul Sabatier, who found that elevated temperatures and pressures could turn hydrogen and carbon dioxide into methane and water.
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.
