AsiaOne has launched EarthOne, a new section dedicated to environmental issues — because we love the planet and we believe science. Find articles like this there. An international team of scientists say they have found a new way to extract water from bone-dry air to produce hydrogen, which they call “the ultimate clean energy”. The researchers said the device could be used in an arid environment where relative humidity was as...

You can’t squeeze blood from a stone, but wringing water from the desert sky is now possible, thanks to a new spongelike device that uses sunlight to suck water vapor from air, even in low humidity. The
device can produce nearly 3 liters of water per day, and researchers say future versions will be even better. That means homes in the driest parts of the world could soon have a solar-powered appliance capable of delivering all the water they need, offering relief to billions of people. There are an estimated 13 trillion liters of water floating in the atmosphere...

When kids learn about the planet’s water cycle, they’re taught a simple concept: our atmosphere is filled with water vapor that has evaporated from the bodies of liquid water we see around us. When
the vapor’s temperature gets low enough, it gets turned back into water. The presence of that vapor becomes especially apparent in the summer, when droplets collect on glasses of ice water and air conditioning units drip onto unsuspecting passersby. An Israeli company called Water-Gen does not think of that condensation as a byproduct; instead, it has built machines specifically designed to create and harvest as much...

In a study published Tuesday in Nature Communications, Columbia University researchers present several devices powered by the shrinking and swelling of bacterial spores in response to changes in humidity. The
initial prototypes may look like child's play, but the researchers are convinced that they've only just begun to tap the energy potential of the technology. ... In the new study, his team has cobbled together devices that create lifting and piston-like motions by harnessing the natural tendency of the spores -- which are commonly produced in great quantities for probiotic supplements -- to expand and contract. The devices contain strips...
