A newly discovered “nano-structured” copper alloy could redefine high-temperature materials for aerospace, defence and other next generation engineering projects. The US breakthrough created a copper-tantalum-lithium alloy called “Cu-Ta-Li” with exceptional thermal stability and mechanical strength that’s now seen as one of the most resilient copper-based materials ever produced. Even when subjected to 1472 degrees Fahrenheit—or […]
Blowin’ In The Wind
The town of Ongerup in Western Australia might be tiny, remote and known mostly for wheat, but wind farming could be about to put it on the map. Vestas, one of the world’s biggest wind turbine makers, has plans to build a new wind farm near the town of about 114 people that could see […]
Cutting Infection With Copper
Scientists in the UK have developed copper nanoparticles that can be coated onto implanted medical devices to cut the risk of infection after operations. The Nottingham Trent University study also held out hope that the breakthrough could tackle the over-reliance on antibiotics that has often fuelled antibiotic resistance. In 2019 there were 1.27M deaths globally […]
Chasing Copper’s Clean Dream
The US & China are racing to secure supplies of copper as they realise they’ll need a lot more red metal to make a green world. But that’s not the only race going on. Over demand and dwindling supply means miners will have to either find new, accessible copper deposits—an expensive, long term proposition—or get […]
Rio Tinto’s Smart Move
Rio Tinto has opened the Centre for Future Materials in London to help find cleaner, smarter ways of extracting copper to fuel the renewable energy and electric revolution. It’s an urgent problem. As we now know the world will need a lot more copper if we have any hope of supplying all the electric vehicles, […]
Putting The Battery In Community
I saw the other day that close to 70% of Australians support the need to build more renewable energy projects. That’s huge. No surprise that rooftop solar is the most popular at 80% of course—4M homes already have that—but hydropower at 73%, solar farms at 69%, onshore wind at 60% and offshore wind at 59% […]
Living Green (Literally)
A new copper-clad, energy-generating home on the outskirts of Oxford in Britain is being hailed as both a triumph of style and sustainability. The house—by UK architect Adrian James who’s called it “Copper Bottom”—is green in the most literal sense. The outside of the house is almost all clad in copper, as if the roof […]
Aussie Copper Mining Breakthrough
A brand new Queensland startup has made a breakthrough copper recovery technology that promises to cut costs and boost supply from previously discarded ore. Banksia Minerals Processing—a University of Queensland spin-out—uses ultra-low chemical and energy inputs to enable economic copper recovery regardless of grade or impurities. The electrochemical process aims to slash costs and unlock […]
Mining And Net Zero?
There’s no universal, one size fits all target when it comes to mining & Net Zero, but globally the goal is 2050 according to the Paris Agreement. But it’s a moving feast by country or company, with a wide variety of decarbonisation ambitions and with some preferring not to commit to firm dates at all. […]
Australia’s E-Waste Tsunami
The average Australian produces about 20kgs of e-waste a year, triple the global average of 7kgs, and its about to get a lot worse says a new study. The federal government’s latest national waste report says the country creates 500,000 tonnes of e-waste a year. Sadly only about half of that was recycled in 2022, […]
Clean Energy From “Copper Leaves”
American and English scientists have developed tiny nano copper ‘flowers’ that bloom on artificial leaves to make clean energy and fuel using just sunlight. The global project by Cambridge and Berkeley developed a practical way to make hydrocarbons—molecules made of carbon and hydrogen—powered solely by the sun. A totally unique approach. By combining a light […]
Big Climate Goals Need Big Energy Storage
I’ve talked a lot about all the great rooftop solar & energy storage happening in our homes, but it will mean nothing if we don’t charge up the national electricity grid too. That came home to me this week when I read a new snapshot out of Monash University called The Storage Imperative: Powering Australia’s […]
