Canadian scientists are tackling climate change, one air-sucking wall at a time.
Think of it as a giant, high-tech, carbon-dioxide-sucking Lego wall. …They’re a thing. We love them. We also know they’re hard to come by on the Internet. That’s why we have a team of fact-checkers double-checking everything we post, with standards that meet or exceed anyone else on the Read More...
Hydrogen-powered iPhone 6 lasts a week without recharging
British company Intelligent Energy is reportedly working with Apple to create a hydrogen fuel cell system that could keep an iPhone 6 charged for a whole week. A British company thought to be working closely with Apple has created a hydrogen fuel cell for an iPhone 6 that allows the device to go a Read More...
Toyota has sold about 8 million hybrid cars, saving 5.8 billion gallons of gasoline
Prius is latin for "to go before", and the name suits Toyota's car, the first mass-produced hybrid vehicle in the world. It's now 20 years ago that a concept car version of the Prius hybrid was shown at the Tokyo Motor show in 1995. The car went into production in 1997 and has since inspired many Read More...
Researchers use solar power to make carbon fiber out of thin air
Carbon capture is an idea that’s been around for a while, but it’s always seemed like a bit of an afterthought, a way to slightly slow the pace at which we’re pumping carbon dioxide into the atmosphere. But what if we could do at a scale that would suck all the carbon we’ve emitted since Read More...
In climate change era, new idea for conservation takes shape
Conservation has long been about protecting communities of plants and animals where they are. But climate change is leading to a nascent form of conservation that embraces change and instead seeks to provide a thriving stage on which it can happen. Chester, Mass. — It's a late-July morning, Read More...
This ‘artificial leaf’ could be the cleanest, most efficient source of renewable energy on Earth
When we think of solar power, we usually think of solar panels, but we should really be thinking about plants. After all, plants are the original solar power generators, turning the sun’s rays into energy through the process we all learned about in biology class: photosynthesis. Researchers Read More...
Coal mining sector running out of time, says Citigroup
Industry unlikely to pick up without advances in carbon capture technology as governments seek to drive down emissions, banking giant warns. RTCC reports US banking giant Citigroup says the global coal industry is set for further pain, predicting an acceleration of mine closures, li uidations and Read More...
The rise of the soil carbon cowboys
Ranching is a rare occupation. Rarer still are the ranchers pioneering new ways to gra e cattle, transforming their ranches and farms into vibrant ecosystems, producing black ink for their bank accounts and giving their incredibly robust animals a great life (with the exception of one bad day). Read More...
New wastewater treatment method captures carbon and creates renewable energy
You may not spend much thought on cleaning up municipal and industrial wastewater, but you may have guessed it's dirty. Quite dirty, in fact. Wastewater treatment produces carbon dioxide (CO2) emissions by powering the whole machinery (and this requires high amounts of energy) and by decomposing Read More...
Rewilding: Movement to restore wilderness areas is growing across Europe
Rewilding is probably the most exciting thing happening to the conservation movement. It's aimed at restoring and protecting natural processes and core wilderness areas, reintroducing keystone species that have, in extreme cases, gone extinct. It's a popular trend in Europe. Here's a fascinating Read More...
