1:23 PM | Biomass Powered Fuel Cell That Can Be Charged From a Campfire Developed
How do you charge a cell phone if you don’t have access to electricity? This question is especially relevant in developing countries where a large portion of the population may live without electricity or toilets or running water but yet they own cell phones. A new technology developed at Lawrence Berkeley National Laboratory will allow people to get enough electricity to charge a cell phone or to power a lightbulb form a simple campfire. Read more »

3:25 PM | Researchers Receive a Grant to Test High Temperature Water Splitting
Hydrogen fuel is a zero-emission fuel that can potentially be mass-produced and commercialized for passenger vehicles and aircraft. However since pure hydrogen does not occur naturally, it takes energy to manufacture it. Most currently available hydrogen production processes are either costly or too complex or negatively affect the environment. Scientists from the South Dakota School of Mines and Technology are studying a new way to produce hydrogen on a large scale. Read more »

1:00 PM | Well-tie workflow
We've had a couple of emails recently about well ties. Ever since my days as a Landmark workflow consultant, I've thought the process of calibrating seismic data to well data was one of the rockiest parts of the interpretation workflow—and not just because of SynTool. One might almost call the variety of approaches an unsolved problem. Tying wells usually involves forward modeling a synthetic seismogram from sonic and density logs, then matching that synthetic to the seismic reflection […]

7:24 PM | Rivers Carry Away Waste Heat Form Power Plants at a Cost to the Environment
Two computer models developed by the scientists from the University of New Hampshire show a detailed picture of how thermal power stations interact with climate, hydrology, and aquatic ecosystems. For example, models suggest that while rivers serve as “horizontal cooling towers” that provide an important service to the regional electricity sector, this comes at a cost to the environment.

5:41 PM | Scientists Develop Faster and More Durable Fault Current Limiter to Mitigate Blackouts
A local power failure in Ohio ten years ago caused a series of cascading power failures that resulted in a massive blackout that affected 50 million people and caused billions of dollars in damage and lost revenue. Power failures are particularly critical at sites where the environment and public safety are at risk. A new piece of equipment developed by engineering researchers at the University of Arkansas can prevent power failures by regulating or limiting the amount of excess current that […]

4:08 PM | Mechanism Behind LED Efficiency Loss at High Currents Identified
Scientists from the University of California, Santa Barbara together with colleagues from the École Polytechnique in France, have conclusively identified Auger recombination to be the mechanism that causes light emitting diodes (LEDs) to be less efficient at high drive currents. This explains the phenomenon known as LED “droop”—a mysterious drop in the light produced when a higher current is applied. The cost per lumen of LEDs has held the technology back as a viable replacement for […]

5:19 PM | Are We Ignoring the Most Important Science About the Gulf Spill?
By Rachel Nuwer After the Exxon Valdez dumped 11 million gallons of crude oil into Alaska’s Prince William Sound in 1989, a pod of orcas there stopped having babies. The whales have yet to birth a single calf in more than 20 years, and scientists now consider those orcas to be functionally extinct. (See “The Woman Who Loves Orcas,” Spring 2013.) The oil would certainly seem to have something to do with it, but we don’t know for sure. Why? Because […]
