Nanotech textile converts air humidity into clean drinking water
More than two billion people live in countries affected by a lack of clean drinking water. Soon, a Canadian innovation — inspired by a biological adaptation found in certain lizard species — will make it possible for people to pull a glass of water right out of the air. The company, called Read More...
Scientists are finding ways to harness energy and recover metals from wastewater
The average American uses a staggering 60 gallons of water per day for purposes that include flushing toilets, showering and doing laundry. This figure can easily double if outdoor uses, such as watering lawns and filling swimming pools, are also included. Most of that water eventually will become Read More...
A step-guide to solving the global water crisis
For many people, a clean drink of water isn’t a certainty. Right now an estimated 1.2 billion people live in areas with chronic water scarcity, and upwards of 4 billion — two-thirds of the world’s population — experience shortages at least one month a year. As bad as this sounds though, Read More...
The waste product of desalination plants could be used to desalinate more water
When salt is removed from seawater in desalination plants, the byproduct is – not surprisingly – a lot of highly-concentrated salty brine. Ordinarily, this is just dumped back into the sea, which can harm the environment. Thanks to researchers at MIT, however, that brine could soon be used to Read More...
Seawater turns into freshwater through solar energy: A new low-cost technology
A study conducted at Politecnico di Torino and published by the journal Nature Sustainability promotes an innovative and low-cost technology to turn seawater into drinking water, thanks to the use of solar energy Read More...
Seawater to freshwater through solar energy: A new low-cost technology
According to FAO estimates, by 2025 nearly 2 billion people may not have enough drinking water to satisfy their daily needs. One of the possible solutions to this problem is desalination, namely treating seawater to make it Read More...
A water treatment breakthrough, inspired by a sea creature
Inspired by Actinia, a sea organism that ensnares its prey with its tentacles, a team of researchers has developed a method for efficiently treating water. The research, a collaboration of the labs of Yale's Menachem Elimelech and Huazhang Zhao of Peking University, used a material known as a nano Read More...
Carbon neutral solution for desalination: Tapping into geothermal sources
Water shortages are hitting some areas of the world hard, and with increasing global temperatures, more regions may be experiencing drought conditions. Countries such as Saudi Arabia rely on desalination plants to provide drinking water to their residents, producing 5 million cubic meters of Read More...
An ingenious way to bring clean water to a slum
Gangs control the water supply in much of Nairobi's Kibera slum. This is how one man used an innovative idea to take them on and bring clean water to the Read More...
How recycled water could revolutionize sustainable development
By 2025, absolute water scarcity will be a daily reality for an estimated 1.8 billion Read More...
