If the world ever turns into a post-apocalyptic desert landscape, you'll probably have to look for dust storms and violent cyclist bands. But you may not have to worry about finding enough water.
This is because an Ohio State University (OSU) research team has been studying how some of the desert's most efficient water collectors can literally pull water out of the air. and what they have learned could help us to have enough clean drinking water before or after the collapse of the social order.
Under the Surface
In a study published in The Philosophical Transactions of the Royal Society on Monday researchers from OSU describe how cacti, desert grass and desert beetles collect water from the mist at night over the Desert is falling. The researchers then used 3D printers to create surfaces that mimic the natural of these three desert inhabitants.
They covered some of the surfaces in grooves similar to those that help a desert grass direct water toward the roots. Other surfaces had cones that were supposed to mimic the water-collecting spines of the cactus.
Researchers also tested various materials, including heterogeneous materials ̵
Then they tested the various surfaces by placing them in a room with a humidifier. The result: They found that the best surface for water extraction would be a heterogeneous material and several grooved cones, each with 45 degrees of inclination.
The researchers believe that a large-scale structure is built on their findings Findings could one day collect water from fog or condensation that people could drink in arid environments.
"Water supply is an extremely important issue, especially for people in the driest parts of the world," said researcher Bharat Bhushan in a press release report. "By using technologies with biological inspiration, we can help provide clean water to people around the world as efficiently as possible."
