Alcoa of Pittsburgh, PA set a goal to raise the beverage can recycling rate in North America from its current 52 percent to 75 percent by 2015. The U.S. produces more than 1.5 million metric tons of aluminum cans per year. The recycling rate for cans has fallen steadily from its high of 68 percent in 1992. By comparison, Brazil and Japan both recycle more than 90 percent of its cans.
Moving from 52 percent to 75 percent would have a big impact on clean air. Moving to 75 percent recycling would mean a savings of 600,000 metric tons of aluminum. That’s equal to a savings of 1,286 MW of electricity, the equivalent of two averaged-sized coal-fired power plants running 24/7. Alcoa is working with a number of recycling organizations to raise recycling rates. The company has also expanded its recycling capacity in anticipation of high recycling rates.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
