Just add water – revolutionary 3D printing ink has a salty secret weapon

The 3D printing of certain items could soon get a lot faster, simpler and more eco-friendly. That’s because scientists have developed a new 3D printing ink which is easily extruded as a liquid, but then solidifies on contact with a saltwater solution.C… Continue reading Just add water – revolutionary 3D printing ink has a salty secret weapon

Seawater plant will capture 10 tons of CO2 and make 300 kg of H2 per day

After successful pilot programs, UCLA has partnered with Singapore’s national water agency and others to build the world’s largest ocean-based carbon dioxide removal plant capable of removing 3,650 metric tons (8,046,873 lb) of the greenhouse gas per y… Continue reading Seawater plant will capture 10 tons of CO2 and make 300 kg of H2 per day

Antarctica’s mysterious Blood Falls aren’t made by minerals after all

A bright red waterfall isn’t something you’d expect to see on the icy landscape of Antarctica, but that’s exactly what’s pouring out from the foot of Taylor Glacier. A team of scientists now claims to have solved the long-standing mystery behind the cr… Continue reading Antarctica’s mysterious Blood Falls aren’t made by minerals after all

Teflon-like desalination membrane purifies water fast and friction-free

Engineers at the University of Tokyo have developed a new type of desalination membrane that they claim is faster, and requires less pressure and energy than existing tech. The new membrane is made up of a series of nanoscale tubes lined with a Teflon-… Continue reading Teflon-like desalination membrane purifies water fast and friction-free

$4 solar desalination system produces a family’s daily drinking water

Desalination is being explored as a way to solve the shortages of drinking water that plague much of the world, but it has a few issues to iron out. A new design for a solar-powered desalination device prevents the build-up of salt, making for an effic… Continue reading $4 solar desalination system produces a family’s daily drinking water

Sunlight and salt water join forces in electricity-free cooling system

There are many parts of the world which lack infrastructure, but that get a lot of sunlight … which makes buildings uncomfortably hot. A new system could help, as it uses a combination of sunlight and salt water – but no electricity – to produce a co… Continue reading Sunlight and salt water join forces in electricity-free cooling system

Strange salty “crystal critters” help thwart fouling of metal surfaces

Pipes, instruments and surfaces that come into contact with salty water usually end up with a corrosive layer of salt and other dissolved minerals caked on, which needs to be scraped or washed off. Now, engineers at MIT have developed a new method for … Continue reading Strange salty “crystal critters” help thwart fouling of metal surfaces

Efficient solar desalination unit uses titanium-coated diaper material

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

Solar-powered desalination systems could bring water to disaster zones

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
