Comments Off on Water purification breakthrough can even clean water from the Dead Sea

Despite all our advances, access to clean water is still a major problem – not just for developing nations, but here in the US, where water shortages during natural disasters can cost lives. Scientists have created a cost-effective technology that addresses this problem using hydrogels. Using ambient solar energy, these gel-polymer hybrid materials can produce clean water from any source – including salt water from the Dead Sea. A team led by Guihua Yu at the University of Texas Austin created a hydrogel that is both hydrophilic and semiconducting. “We have essentially rewritten the entire approach to conventional solar water evaporation,” Yu said. The system works by creating water vapor under sunlight and then pumping the vapor into a condenser to deliver the freshwater. It also filters out contaminants that are harmful when consumed.

However, current distillation technologies, such as multi-stage flash and multi-effect distillation, require significant infrastructures and are quite energy-intensive,” said Fei Zhao, a researcher involved in the project. Tests produced 25 liters of water per square meter – plenty for disaster-stricken areas or household use. Via Phys.org Images via UT at Austin

China’s new rain-making system could increase rainfall by billions of cubic feet

Comments Off on China’s new rain-making system could increase rainfall by billions of cubic feet

China needs water — and their answer to the issue is a massive weather modification system being developed by the China Aerospace Science and Technology Corporation (CASC). South China Morning Post (SCMP) reported the country is testing technology that could increase rainfall in the Tibetan Plateau by as much as 10 billion cubic meters, or around 353 billion cubic feet, every year. Will a huge rain-making system help China with water issues ? SCMP said they plan to build tens of thousands of chambers across the Tibetan mountains to generate rain over an area of around 620,000 square miles, or “three times the size of Spain.” The chambers will burn solid fuel to create silver iodide, which SCMP described as a “ cloud-seeding agent with a crystalline structure much like ice.” They said the chambers will be located on steep ridges facing the south Asia monsoon . Wind striking the mountain will produce an upward draft, carrying particles into clouds to bring about rain. Related: World’s largest fog harvester produces water from thin air in the Moroccan desert Real-time data from 30 weather satellites , each one watching monsoon weather above the Indian Ocean, will guide daily operation of the chambers. The ground-based network will also draw on cloud-seeding methods with drones , planes, and artillery to maximize the impact of the system, according to SCMP. A researcher on the project told SCMP, “[So far,] more than 500 burners have been deployed on alpine slopes in Tibet, Xinjiang, and other areas for experimental use. The data we have collected show very promising results.” The publication said although the idea isn’t a new one, China is the first country to try “such a large-scale application,” and  space scientists designed and built the chambers with “cutting edge military rocket engine technology.” Via South China Morning Post Images via Depositphotos and Eutah Mizushima on Unsplash

Meridian Line launches ethically sourced, organic cotton jeans for the outdoors

Comments Off on Meridian Line launches ethically sourced, organic cotton jeans for the outdoors

Adventure calling? Gear up with Meridian Line, a range of eco-friendly denim designed for conquering the great outdoors. Available for pre-ordering through Kickstarter , the men’s and women’s jeans infuse ethically sourced organic cotton with two percent spandex to allow “freedom of movement without looking like you just stepped out of yoga class,” according to the Kansas City, Missouri–based firm. Meridian Line is the brainchild of artist Jeremy Collins, who launched the company with a series of graphic T-shirts and accessories in 2014. Two years later, Collins enlisted Benji Thrasher, formerly the lead designer at Prana , to kick Meridian Line’s offerings up a notch; the jeans emerged from the drawing board shortly after. But active performance isn’t the denim’s only twist. Each pair of pants also boasts artwork by Collins on the inner pockets, yoke, and turn-ups. The print is based on one of Collins’s signature pieces: a greenery-ringed compass inset with a salmon and an eagle at play (or perhaps prey?) in a yin-yang configuration. Meridian Line’s denim is “built for outdoor activities, travel, and a casual, dareful, or professional lifestyle,” Collins and Thrasher said. “Our jeans are made to go wherever you do: urban, mountain, or board meeting.” Prices for both men’s and women’s styles start at an accessible $79, or 20 percent less than what the jeans will cost when they hit retail outlets later this year. If you’re looking for the whole top-to-toe look, a pledge of $105 will snag you a pair of jeans, an exclusive tee, and a trucker hat. + Meridian Line at Kickstarter + Meridian Line
