Power Management Experts Seek To Cooperate On Solar Energy
The earth receives more energy from the sun in just one hour than the world uses in a whole year. But although that energy holds tremendous potential for creating inexpensive, environmentally clean electricity, that potential is far from being realized on a large scale.

AC/DC, The Savage Tale of the First Standards War
There is not a day that goes by that we do not hear about an on-going battle for supremacy in some field of electronics. Given my coverage of communications in ED, I hear about the wireless standards battles that never seem to end. In browsing my local Barnes & Noble book store recently, I ran across a book that describes the first ever standards battle.

The RHC series of resistors employs a special resistive element and coating that offer better heat transfer to the ambient air and are more tolerant of the higher temperatures associated with higher power.
Lightning Strikes Steinmetz's Curiosity
Like Benjamin Franklin, Charles Proteus Steinmetz was drawn to understanding and studying lightning. Lightning, he said, was an example of electrical transients because it reflects changes in electrical circuits of very short duration. The result of these studies was his theory of traveling waves. It opened the door to his creation at General Electric of methods to protect high-power transmission lines from lightning strikes. His last major project at GE was part of this research....
"North American Component Distributors Should Demonstrate Rohs Compliance Too," Says Newark InOne
The European Union's Restriction of Hazardous Substances (RoHS) law, which took effect July 1, puts the legal responsibility for demonstrating compliance on the producers of finished electrical or electronic devices. Leading North American electronic components distributor Newark InOne, a subsidiary of global Premier Farnell plc, believes that component distributors must meet the same standards if they are to provide their customers with the assurance they need to meet the legal requirements.

Rooftop PV Data Predicts Solar Energy Yield
The National Institute of Standards and Technology (NIST) began a 15-month research project to determine the effectiveness of new generations of photovoltaic (PV) roofing products. At its new Roof Photovoltaic Test Facility...
The Fire Next Time?
Last week’s media feeding frenzy over Dell’s recall of 4.1 million laptop battery packs, followed by this week’s recall of 1.8 million Apple battery packs has some worrisome aspects. I wish I knew more than I do at this point. Here’s the short version: if you abuse a lithium battery, it can experience a “discharge with flame” and you can’t put it out...
