Increased productivity, not less energy use, results from more efficient lighting

August 7, 2012 4:12 am | News | Comments

In 2010, Sandia National Laboratories researcher Jeff Tsao and Harry Saunders of The Breakthrough Institute in Oakland, Calif., predicted that light-emitting diodes would have a similar improvement in productivity—but not less energy use—that occurred upon the introduction of the Edison light bulb. Now, they have reprised their report to emphasize conclusions they say were misinterpreted by the media.

Nanodevice builds electricity from tiny pieces

July 9, 2012 6:38 am | News | Comments

A team of scientists in the U.K. have developed an electron pump—a nano-device—which picks these electrons up one at a time and moves them across a barrier, creating a very well-defined electrical current. This technique, which manipulates electrons individually, could replace the traditional definition of electrical current, the ampere, which relies on measurements of mechanical forces on current-carrying wires.

Sensor measures power consumption quickly, easily

May 16, 2012 10:57 am | News | Comments

Thanks to new energy taxation regulations taking effect in Germany, electrical engineers there have invented a space-saving energy usage metering unit that can be simply clipped onto a power cable like a laundry peg, without having to disconnect the load. The device is based on a magnetic field sensor originally developed for use in washing machines, where it monitors the position and orientation of the rotating drum.

Spin polarized supercurrents optimized with a simple flip

May 14, 2012 5:52 am | News | Comments

Researchers from Michigan State University, the NIST Center for Neutron Research, and the NIST Center for Nanoscale Science and Technology have discovered the key to controlling and enhancing the lossless flow of a current with a single electron spin state in a standard superconducting device.

Infrared LEDs can be made cheaper, compatible with silicon

May 10, 2012 3:31 am | by Anne Ju, Cornell University | News | Comments

Light-emitting diodes (LEDs) at infrared wavelengths are the magic behind such things as night vision and optical communications. Cornell University researchers have advanced the process of making such LEDs cheaper and easier to fabricate, which could lead to ultrathin LEDs painted onto silicon to replace computer wiring with light waves.

Engineers work toward electric mass mobility

May 3, 2012 5:45 am | News | Comments

Electric vehicles have slowly been catching on in urban environments, but their popularity has been hampered by available manufacturing technology. Either the vehicles are too heavy and too expensive, or they do not meet mass-market safety requirements. Researchers in Germany, funded by major automotive corporations, are testing a new mobility concept they hope will hit the sweet spot.

New Output Voltage Ranges for Power Converters

April 30, 2012 8:45 am | Product Releases | Comments

Schaefer, Inc., has broadened capabilities for its Raptor Series of military COTS/MOTS power supplies. The output voltage range has been extended to provide DC outputs from 12 VDC to 52.5 VDC with power ratings from 1200 W to 1800 W.
