A newly designed material, which mimics the wing structure of owls, could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics.
A team of scientists say they’ve found a way to make a battery cathode with a hierarchical structure where the reactive material is abundant yet protected — key points for high capacity and long battery life.
Metal powders, produced using clean primary energy sources, could provide a more viable long-term replacement for fossil fuels than other widely discussed alternatives, such as hydrogen, biofuels or batteries, according to a new study.
Finding a technology to shift carbon dioxide, the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products.
Energy Politics | Environment and Sustainability | Solar PowerFrance keeps making green headlines lately… the Eiffel Tower’s wind turbines, the tree-shaped wind turbines being installed in Paris, and now an exciting new law that is sure to have a huge environmental impact in urban centers. Every new commercial building in France must meet a new building requirement; the roof must be at least […]
adminBulletproof vests and other super-strong materials could soon become even tougher and more environmentally friendly at the same time with the help of extra firm, or ‘al dente,’ fibers. Researchers report an innovative way to spin high-performance polyethylene fibers from natural fats, such as oils from olives and peanuts.
A shorter version of this story appeared originally in the Toronto Star. By Tyler Hamilton As oil giants headquartered in Calgary face the reality that the best days for their industry could be behind them, the towns of Chetwynd and Dawson Creek in northwestern British Columbia hold out hope that better times lie ahead. It is on about 1,000 acres of land straddling both municipalities that a small B.C.-based company called Blue Fuel Energy plans to build an industrial-scale refinery that could create enough low-carbon gasoline to fuel 20 per cent of vehicles in Canada’s third-largest province. Called the Sundance Fuels project, it’s expected to create about 1,500 construction jobs and another 150 permanent positions. But beyond a boost to the local economy, the project carries …
