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.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
