A few of our readers have weighed in on what a group of Chevy Volts should be called. You may recall that we suggested a group of Volts might be Chevy Voltage. Reader Jim Hutchison suggests calling it a Shock of Volts, and he can't wait GM starts announcing fleet buys in kilo-Volts. But reader Art Sobel thinks Wattage might be a better moniker.

CSA, the standards and compliance testing organization, is cosponsoring with EE&T an event coming up in Feb. in Orlando, that will cover topics that include lighting technology and meeting new Energy Star compliance standards. Speakers include EPA's program manager for Energy Star lighting. Check out the program at eetweb.com/conferences/illuminate. Read More
Wireless Sensor Networks – An Introduction to Technologies and Architectures
This overview webcast from National Instruments provides an introduction to wireless sensor networks, including application areas and typical system components. The webcast then explores technology considerations for wireless sensor networks, including network topologies, communication standards, and power consumption. View webcast now.
A group of Georgia Institute of Technology researchers have fabricated super-small nanoscale power generators able to generate enough power to run a small LCD. The nanoscale generators that harvest mechanical energy from the environment using an array of tiny nanowires. Merely compressing a nanogenerator between two fingers puts out enough energy to run the small display. READ MORE Read More
Rugged Speed and Temperature Sensor
Electro-Sensor's TT420 Temperature Transmitters and ST420 Shaft Tachometers are pre-calibrated, proven solutions that install fast and perform anywhere, providing rugged and reliable monitoring solutions for your toughest machine environments. The TT420 combines a temperature sensor, signal conditioning, and 2-wire loop-powered 4-20mA transmitter into one compact package. The ST420 detects magnetic pulses from a rotating shaft-mounted magnetic pulser target (disc or wrap) and outputs a smooth, continuous 4-20mA analog signal in direct proportion to the pulse frequency (rotating shaft speed).
There's more than one way to ascertain what loads are drawing what power in your house. Non-intrusive load monitoring could do the job without necessitating the installation of a smart meter. The idea behind NILM is to first characterize the way big loads in your house typically behave, then just monitor the main power meter going to the house. READ MORE Read More

Researchers at Case Western Reserve University recently got DoE funding to perfect a super-capacitor that would provide a 10-fold or better energy density than current models, yet would be a fraction of the size and weight. The new design could also be quite reliable because it can heal leaks of electrical current that plague models now in use. The key factors are the materials and design of the device. The anode of the capacitor is a titanium alloy so finely textured that it absorbs almost all the light hitting it. READ MORE Read More
Support Across the Board
Now, you can have it all, faster and easier than ever before. Avnet's commitment to customer service is backed by an extensive product offering combined with supply chain and design chain services and a world-class ecommerce offering. Ready. Set. Go to Market.
Quick-service restaurants could cut their energy bills by between 41 and 52% if they adopted measures suggested by the DoE's Pacific Northwest National Laboratory. Moreover, PNNL figures the payback period for installing the energy efficient gear would be a little over two years. PNNL researchers modeled a typical quick-service restaurant and figured the savings based on typical usage rates for equipment and restaurant square footage. READ MORE Read More
