A plurality of Volts

If a group of lions is a pride and a group of sheep is a flock, is a group of Chevy Volts.....Chevy Voltage?? That's not such a wild question as organizations such as GE announce fleet buys of the mainly electric Volt. You'll be able to read more about our experience with the Volt in the Nov.-Dec. issue.

How to build fuel-efficient planes

The Wright brothers only made progress in powered flight when they stopped trying to mimic birds and started their design work from a clean sheet of paper. Now, the opposite approach may be the means through which designers realize more fuel-efficient planes. So say researchers Geoffrey Spedding, an engineer at the University of Southern California, and Joachim Huyssen at Northwest University in South Africa. READ MORE Read More

Standards for high-brightness LEDs

SEMI, the organization for semiconductor manufacturers, has formed a new organization to set standards for high-brightness LEDs (HB-LEDs. The goal is to eliminate costs across the LED industry and boost innovation in equipment and processes. The committee has already set up task forces in four areas: wafers, carriers, automation, and assembly.The automation task force will come up with a standard that facilitates compatibility among different types of HB-LED equipment from different vendors.

Wind turbine noise: Serious problem or just an annoyance?

As more wind turbines get built and more powerful units come on line, there are a rising number of complaints about noise and the potentially harmful side effects of living near them. The complaints are coming from Japan, Germany, Britain, Australia, and the U.S. Most victims say they suffer from insomnia, headaches, heart palpitations, dizziness or buzzing in the ear, and stress. In response, industry groups including the American Wind Energy Assoc., and the Canadian Wind Energy Assoc., sponsored a report concluding that there is no evidence that audible or sub-audible sounds emitted by wind turbines have any direct adverse physiological effects.
