Pollution-free power becoming a reality
Alternative green energy resources are becoming a reality due to advances in fuel cell technology done by Cummins Power Generation. Xin Li, senior researcher in the fuel cell field who works with Cummins Power Generation, predicts that on the basis of current progress, Solid Oxide fuel-cell based mobile power products will be commercially available in as soon as 2 to 3 years and higher powered 100-kW stationary power units will become available in 7-10 years. Fuel cell technology, the pollution-free electricity generation technology, which provides a green alternative to the combustion of gasoline and other fossil fuels, is anticipated to become the main source of energy to power electrical cars, trucks, buses and even homes. Functioning similar to a battery, which uses electrochemical conversion, fuel cells produce electricity from fuel (on the anode side) and an oxidant (on the cathode side), which react in the presence of an electrolyte. Solid Oxide Fuel Cells (SOFC), which operate on a mixture of hydrogen and carbon monoxide, are more compatible with existing fuel infrastructures including natural gas and the only by-products are water vapor and a small amount of carbon dioxide. In 2007 Cummins Power Generation was one of six industry teams involved in the Dept.

Can you envision an Energy Corps?
View the full story, including all images and figures, in our monthly digital edition In the comic strip “Peanuts,” Lucy is forever fooling Charlie Brown by taking away the football just as his foot is about to kick it. This is what seems to happen with our reaction to energy. Even after numerous shortages, price spikes, and other energy crises, we are hesitant to make investments because paybacks calculated during high-price periods get extended when energy prices drop back down, and the paybacks don't seem to materialize. In Japan's bullet train, the ticket aisles normally have open gates that energize closed if someone's ticket is not valid.
Energy Star Revises Program for Residential Ventilating Fans
AMCA International, the Home Ventilating Institute (HVI), and Energy Star recently teamed up to revise the Energy Star program requirements for residential ventilating fans. The goal was to provide residential consumers with energy-efficient, quality ventilation products without sacrificing features, style, or comfort. This collaborative effort resulted in revising the testing requirements, and partners (companies that participate in the Energy Star program) now have more options as to where they can test their products for Energy Star qualification, including AMCA's testing laboratory at the AMCA headquarters in Arlington Heights, Ill. The revised program went into effect on January 15, 2009. The new requirements in the program do not grant exclusive rights to any organization to certify, verify, or challenge-test Energy Star-qualified products or products applying for Energy Star qualification.

Storage management system
The Smart Grid storage management system from S&C Electric Company performs dc-to-ac energy conversion and controls charging and discharging algorithms. A pad-mounted step-up transformer converts ac system output to line voltage. The system can be installed with SCADA-Mate switches equipped with an automatic restoration system, which can supply stored energy if power to the feeder is interrupted. S&C Electric Circle 455.
Built in accordance with MIL-STD-2003 and tested per MIL-STD-202G, and method 301 and 302, the circular MIL connector custom cable assemblies from Electro Standards Laboratories are designed for military and shipboard applications. The cable assemblies range in wire gauges from 0 to 26 AWG and high density contact arrangement are available in miniature circular shells. www.ElectroStandards.com #3.
The expanded line of transformers manufactured by Hammond Power Solutions improves the total power factor and maximizes energy savings through the use of phase shifting. The Sentinel, Synergy, and Centurion models meet NEMA TP-1-2002 standards. The Sentinel is designed for linear loads, while the Synergy series addresses harmonic activity associated with nonlinear loads.
Sustainable air conditioning leads to sustainability
View the full story , including all images and figures, in our monthly digital edition When the temperature rises above 100 F in the summer, air conditioning systems stretch the electrical grids beyond their limits, while cars and trucks choke the air in towns and cities. Politicians and energy companies want to build a “more robust” electrical grid and build “safe nuclear” and “clean coal” power plants, costing trillions of dollars and creating more greenhouse gases. Let us envision a world 20 years in the future when most homes and buildings are electricity generators rather than users, and most public and private transport runs on clean electricity. The electrical grid redistributes surplus electricity from sustainable buildings to energy-intensive buildings and public transport during the day, and recharges electric cars and trucks at night. This vision has buildings using little electricity, and most buildings producing more electricity than they use during hot weather.
Snubbers: Protecting medium-voltage transformers from electrical transients
A snubber is a resistor-capacitor (RC) network that is designed for the system. Snubbers are a cost-effective method of reducing switching-induced transients. At many installations that use medium-voltage switching, transformer damage is often attributed to lighting.
