IWMI helps improve livelihoods of resettled community in Mullaitivu

by International Water Management Institute (IWMI)  (Sep. 1, 2014)

Drive carefully along the rutted road. Red soil and sparse vegetation bathed in dust greet you on every side, shimmering in the hot, dry, heat. An occasional village relieves the monotony of the lonely landscape. Here is a stark beauty that defies description. Then, a sudden burst of life. Children, chattering excitedly, run to meet your vehicle, ...

Rubber meets the road with new ORNL carbon, battery technologies

by Oak Ridge National Laboratory  (Aug. 27, 2014)

Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers at the Department of Energy’s Oak Ridge National Laboratory. By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a ...

Atlantic depths may hold key to heat hiatus

by GLOBE Foundation  (Aug. 22, 2014)

For years, researchers have puzzled over the temperature rises that haven’t happened – but scientists in China and the US believe they have cracked the mystery of the missing heat. While calculations indicate that global average temperatures should be rising predictably, the planetary thermometers tell a different ...

The 2050 Imperative–Carbon Neutral Cities

by GLOBE Foundation  (Aug. 20, 2014)

The International Union of Architects (UIA) has adopted a Declaration committing its member organizations and partners to exercise leadership in planning and designing sustainable, resilient, carbon-neutral and healthy built environments in the world’s cities and towns.

Steam from the sun - New spongelike structure converts solar energy into steam

by MIT - Massachusetts Institute of Technology  (Jul. 21, 2014)

Original story at MIT News The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the ...

Solar ammonia process may spur fertiliser revolution

by SciDev.Net  (Sep. 4, 2014)

Low-energy ways to make ammonia — a vital constituent of fertiliser — could enable developing countries to manufacture their own fertiliser instead of importing it. One such technology published last month (8 ...

Getting a charge out of water droplets

by MIT - Massachusetts Institute of Technology  (Jul. 14, 2014)

Original story at MIT News Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be ...
