New Tech for Grid-Level Electrical Energy Storage
Posted in Batteries, Energy Storage, Solar Power, Wind Power, Energy Efficiency, Renewable Energy, Energy, News on Wednesday, 11 July 2012
Electrical energy storage is the obstacle preventing more widespread use of renewable energy sources. Due to the unpredictable nature of wind and solar energy, the ability to store this energy when it is produced is essential for turning these resources into reliable sources of energy. The current U.S. energy grid system is used predominantly for distributing energy and allows little flexibility for storage of excess or a rapid dispersal on short notice. Drexel University researchers believe they have a solution.

Carbon Nanotubes Help Energize Fuel Cells and Metal-Air Batteries
Posted in Batteries, Alternative Fuels, Energy Storage, News on Monday, 25 June 2012
Fuel cells, which use chemicals to create electricity, hold promise in a variety of areas but the high price of platinum catalysts used inside the cells has provided a roadblock. One promising low-cost alternative to platinum is the carbon nanotube – an excellent conductor of electricity. Multi-walled carbon nanotubes riddled with defects and impurities on the outside could eventually replace some of the platinum catalysts used in fuel cells and metal-air batteries, according to Stanford University scientists.

Coaxial Nanocable Could Aid in Energy Storage
Posted in Batteries, Electronic Components, Energy Storage, Energy Efficiency, News on Friday, 08 June 2012
Researchers at Rice University have created a coaxial cable that is about a thousand times smaller than a human hair and has higher capacitance than previously reported microcapacitors. The nanocable was produced with techniques pioneered in the burgeoning graphene research field and could be used to build next-generation energy-storage systems.

Boosting Nanowires for Better Batteries and Solar Cells
Posted in Batteries, Alternative Fuels, Energy Storage, Solar Power, Renewable Energy, Nanotechnology, News on Tuesday, 01 May 2012
Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.

Boosting Energy Efficiency of Multi-Hop Wireless Networks
Posted in Batteries, Power Management, Energy Efficiency, Communications, Wireless, News on Wednesday, 25 April 2012
Multi-hop wireless networks can provide data access for large and unconventional spaces, but they face significant limits on the amount of data they can transmit. North Carolina State University researchers have developed a more efficient data transmission approach that can boost the amount of data the networks can transmit by 20 to 80 percent.
