Ecological engineering solves unsafe water problems in Bolivia Jan 30th 2013, 13:22 Surrounded by mining, the mountainous region of Potosi, Bolivia is plagued by extensive environmental contamination from past and current mining operations. Researchers have discovered a technique to remove pollutants from water that requires minimal labor costs and is powered by nature itself. | Farms Not Fracking Jan 28th 2013, 01:35 | On January 27, protestors locked down to a giant paper mache pig at a natural gas site in Bessemer, PA. The fracking site sits 4000 feet from Henry Farm, which provides organic poultry and pork products to loyal customers in the region.

| Catalysis: Blueprint for a break-up Jul 5th 2012, 17:33 Computer simulations reveal how rhodium catalysts with 'stepped' surface structures break ethanol molecules into hydrogen atoms and why they are so efficient | New fuel cell keeps going after the hydrogen runs out Jun 30th 2012, 01:19 Materials scientists have demonstrated a solid-oxide fuel cell that converts hydrogen into electricity but can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its fuel has run out. | Sorghum should be in the biofuel crop mix, experts say Jun 20th 2012, 14:09 Sweet and biomass sorghum would meet the need for next-generation biofuels to be environmentally sustainable, easily adopted by producers and take advantage of existing agricultural infrastructure. | Ionic liquid improves speed and efficiency of hydrogen-producing catalyst Jun 16th 2012, 18:55 The design of a nature-inspired material that can make energy-storing hydrogen gas has gone holistic. Usually, tweaking the design of this particular catalyst -- a work in progress for cheaper, better fuel cells -- results in either faster or more energy efficient production but not both. Now, researchers have found a condition that creates hydrogen faster without a loss in efficiency. | New energy source for future medical implants: Sugar Jun 13th 2012, 17:31 An implantable fuel cell could power neural prosthetics that help patients regain control of limbs. Engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose. This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed patients move their arms and legs again. | Green fuel from carbon dioxide Jun 13th 2012, 17:29 Scientists agree that carbon dioxide has an effect on global warming as a greenhouse gas, but we still pump tons and tons of it into the atmosphere every day. Scientists have now developed a new system for producing methanol that uses CO2 and hydrogen. Methanol can, for example, be used as an environmentally friendly alternative for gasoline. The goal of the scientists is to harness the power of CO2 on a large scale and integrate it into the utilization cycle as a sustainable form of energy production. | Environmental benefit of biofuels is overestimated, new study reveals Jun 8th 2012, 14:05 Two scientists are challenging the currently accepted norms of biofuel production. Calculations of greenhouse gas (GHGs) emissions from bioenergy production are neglecting crucial information that has led to the overestimation of the benefits of biofuels compared to fossil fuels, a new analysis shows. | |
