Transparent Insulating Film Could Enable Energy-Efficient Displays
Posted in Batteries, Electronics & Computers, Energy Efficiency, Energy, News, GDM on Monday, 09 November 2009
Johns Hopkins materials scientists have found a new use for a chemical compound traditionally viewed as an electrical conductor (a substance that allows electricity to flow through it). By orienting the compound differently, the researchers have turned it into a thin film insulator, which blocks the flow of electricity but can induce large electric currents elsewhere.

Harvesting Energy from Regular, Day-to-Day Motions
Posted in Batteries, Electronics & Computers, Energy Storage, Renewable Energy, Energy, Hydroelectric Power, News, GDM on Friday, 30 October 2009
Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.

A new type of redox flow battery from the Fraunhofer Institute for Chemical Technology (ICT) offers an advantage for electric cars. If the rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid – as easy as refilling the gas tank.

Could Small Springs Beat Batteries?
Posted in Batteries, Electronics & Computers, Energy Storage, Energy Efficiency, Energy, News, GDM on Friday, 25 September 2009
MIT scientists have found that carbon nanotubes could be formed into tiny springs capable of storing as much energy, pound for pound, as the best lithium-ion batteries - potentially more durably and reliably.

Better Lithium-Based Storage Systems
Posted in Videos, Batteries, Electronics & Computers, Green Design & Manufacturing, Recycling Technologies, Energy Storage, Energy, Transportation, GDM on Tuesday, 22 September 2009
Lithium-ion batteries for advanced vehicles still have issues of safety and costs in terms of materials resources and abundances, synthesis, and recycling processes. Jean-Marie Tarascon, a professor at France's University of Picardie Jules Verne, discusses materials for better lithium-based storage systems.
