It’s one of life’s most frustrating ironies that Earth’s surface is over 70 percent water, but most of that is undrinkable. Desalination is an important technology that may help unlock more drinking water, and now two independent teams have developed new types of solar-powered … [Read more...] about Novel desalination devices use sunlight to provide fresh drinking water

Scientists use an ultra-thin slice of wood to make seawater drinkable
As global warming worsens on our watch, there might eventually come a time when drinking water is harder to come by for a lot of the world. That’s why we need a better way to convert salt water to potable drinking water in case of emergencies. Inspired by the intricate system of … [Read more...] about Scientists use an ultra-thin slice of wood to make seawater drinkable
Scientists have managed to efficiently separate salt from water using sunlight
As competition for freshwater resources intensifies across the world, the prospect of using technology to tackle the problem is a tempting solution. Still, water desalination is one potential solution to the need for alternative sources of freshwater, current procedures are … [Read more...] about Scientists have managed to efficiently separate salt from water using sunlight
We’ve never been closer to sustainable desalination technology
When Cape Town came dangerously close to becoming the world’s first major city to run out of water, it was a wake-up call to all water-pressed cities around the world, such as Mexico City, Say Paulo, and Cairo. As the world’s population grows and climate change pushes … [Read more...] about We’ve never been closer to sustainable desalination technology
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 … [Read more...] about The waste product of desalination plants could be used to desalinate more water
