Collaborate Disseminate
With the rise of the lithium-based battery, demand for this soft, silvery-white metal – the lightest solid element in the periodic table – has exploded. With the race to zero carbon by 2050 gathering steam, forcing the electrification of transport, lit… Continue reading New tech cheaply produces lithium and H2, while desalinating seawater
Water scarcity is one of humanity’s most pressing problems. Now engineers at Caltech have developed a new system that can tap into two different sources to produce fresh drinking water, by purifying dirty water during the day and collecting droplets fr… Continue reading “Micro-tree” hybrid harvester purifies water and wrings it out of air
Desalination is an important technology that may help expand the world’s supply of drinking water. Now, engineers in China have demonstrated a new, relatively simple design for a solar still with a high efficiency and low cost.Continue ReadingCategory:… Continue reading Efficient solar desalination unit uses titanium-coated diaper material
While reverse osmosis is a relatively energy-efficient form of seawater desalination, it is nonetheless made less efficient by a problem known as biofouling. A new membrane coating, however, could address biofouling like never before.Continue ReadingCa… Continue reading New coating could make desalination tech more efficient and less toxic
Desalination systems play an important role in improving access to fresh water, but some types of the natural resource are too salty for current solutions to handle. Such hypersaline water can have salt content as much as 10 times greater than seawater… Continue reading Corrosion-resistant desalination device can handle super-salty water
Access to clean, safe drinking water is a necessity that’s worryingly not being met in many parts of the world. A new study has used a material called a metal-organic framework (MOF) to filter pollutants out of seawater, generating large amounts of fre… Continue reading Highly efficient process makes seawater drinkable in 30 minutes
Whether they’re adventure travellers or people living in developing nations, many folks may find themselves near the ocean and in need of drinking water. That’s where the QuenchSea is designed to come in, as it’s a portable, relatively inexpensive desa… Continue reading QuenchSea offers desalination on-the-go
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 n… Continue reading Solar-powered desalination systems could bring water to disaster zones
Water desalination technologies play a vital role in converting saltwater into freshwater in parts of the world where access to the latter is lacking, but there is plenty of room for improvement. One opportunity for this lies in the materials… Continue reading Wooden filtration membrane promises efficient and more sustainable water desalination
Current approaches to water desalination are tremendously expensive and energy-intensive, so the search is very much on for new technologies that can get the job done more efficiently. Scientists in Melbourne have put forward one rather promi… Continue reading Hydrophilic disc uses solar power to separate salt from water
