Engineers develop smallest device to control light, advance silicon technology

An electrical engineer at the University of Texas at Austin has made a laser light blink while passing through a miniaturized silicon chip, a major step toward developing commercially viable optical interconnects for high performance computers and other devices.

Researchers for decades have sought to harness light as a messenger on silicon chips because light can move thousands of times faster through solid materials than electrons and can carry more information at once, while re

Researchers study energy-saving method for small office buildings

Engineers have developed a method for “precooling” small office buildings and reducing energy consumption during times of peak demand, promising not only to save money but also to help prevent power failures during hot summer days.

The method has been shown to reduce the cooling-related demand for electricity in small office buildings by 30 percent during hours of peak power consumption in California’s sweltering summer climate. Small office buildings represent the majority of

Sandia researchers seek ways to make lithium-ion batteries work longer, safer

Batteries could soon replace standard nickel-metal hydride batteries in hybrid vehicles

As part of the Department of Energy-funded FreedomCAR program, Sandia National Laboratories’ Power Sources Technology Group is researching ways to make lithium-ion batteries work longer and safer. The research could lead to these batteries being used in new hybrid electric vehicles (HEVs) in the next five to ten years.

“Batteries are a necessary part of hybrid electric-gasoli

PNNL Unveils GridWiseTM Initiative to Test New Electric Grid Technologies

’Smart’ Energy Devices and Real-time Pricing Information Enable Increased Options for Consumers, Bringing Power to the People

SEATTLE – Pacific Northwest National Laboratory announced today the launch of the Pacific Northwest GridWiseTM Demonstration projects, a regional initiative to test and speed adoption of new smart grid technologies that can make the power grid more resilient and efficient.

Senator Patty Murray, D-Wash., representatives from the Department of Energy,

Optical wireless and broadband over power lines: High speed, secure Wi-Fi alternative

Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF.

Colored LEDs or light emitting diodes are currently found in the numbers on digital clocks, remote controls, traffic lights and other applications. Recently, white LEDs have emerged in the mark

New wind energy predictions save millions

Risø National Laboratory, Technical University of Denmark, The Danish Meteorological Institute, Elsam and Energi E2 in Denmark have jointly developed a new method for predicting the energy produced by wind turbines. The method will save millions for electricity producers and consumers

In Denmark more than 5,000 wind turbines produce an average of more than 20 per cent of the Danish power consumption.

The electric utilities must supplement wind energy production with power fro
