They may taste great on a pizza, but could onions and garlic be used to help clean up hazardous heavy metals? Research conducted at GGS Indraprastha University in Delhi, India, suggests this is indeed the case.  Read More

What would you do with 64 kg (140 lb) of discarded glossy magazines? That was the question posed of Belgian designer Jens Praet when he got together with Elle Magazine. His response? Make furniture.  Read More

Systems that convert kinetic energy into electric energy have made great strides in recent times, from mobile phone charging bicycle dynamos to tiles that turn footsteps into electrical energy. Recently researchers at Georgia Institute of Technology have come up with what they believe is a more efficient approach – a self-charging power cell that directly converts mechanical energy to chemical energy and stores the power for release as an electrical current.  Read More

Scientists at the University of New South Wales (UNSW), Australia, are developing a novel way to store hydrogen that could help turn it into a viable portable fuel source. The research centers on using synthesized nanoparticles of the compound sodium borohydride (NaBH₄ for those who love chemistry), which when encased inside nickel shells exhibits surprising and practical storage properties including the ability to reabsorb hydrogen and release it at much lower temperatures than previously observed, making it an attractive proposition for transport applications.  Read More

In a bid to help shape the inexorable march toward more efficient wind power, General Electric Power and Water is developing a new fabric-covered wind turbine blade which promises to cut the cost of wind turbine manufacture significantly, while also allowing a larger blade size, and facilitating easier transportation.  Read More

According to the Economist Intelligence Unit's latest Global Liveability Report, the beautiful city of Vancouver in Canada is a pretty decent place to live, ranking third in the world. Its environmental footprint is currently unsustainable, though, prompting officials to hatch an ambitious plan to have Vancouver crowned the greenest city in the world by 2020. Helping things along nicely is a new warm mix paving process that makes use of the kind of waste plastic placed in blue household recycling boxes by conscientious citizens, reducing greenhouse gases and improving air quality along the way.  Read More

Much of the abundant mechanical energy around us is irregular and oscillatory and can be somewhat difficult to efficiently tap into. Typical energy harvesting systems tend to be built for low power applications in the milliwatts range but researchers from New York's Stony Brook University have developed a new patent-pending electromagnetic energy harvester capable of harnessing the vibrations of a locomotive thundering down a stretch of track to power signal lights, structural monitoring systems or even track switches.  Read More

Size, resolution, the underlying display technology, 3D or not 3D, contrast ratio: these are all things one considers before splashing out on a television. How many of us think about energy consumption? The SEAD Initiative (Super-efficient Equipment and Appliance Deployment) is laboring under the apprehension that however many it is, it's not enough. What's it doing about? It's launching Global Efficiency Medal awards to very visibly identify the most energy-efficient flat-panel TVs (and other electronics), and last week it announced its winners ahead of an awards ceremony in January.  Read More

Israel's Eco Wave Power (EWP) has just signed a memorandum of understanding agreement with the Ocean University of China to fund and test its first commercial scale Wind Clapper and Power Wing wave energy generation system.  Read More
