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.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
