Reducing energy consumption is a bit like exercise. People tend to agree it’s a good idea and should do it regularly –– but often times they don’t quite make it to the gym. Yet if energy costs keep rising, engineers won’t be able to sit on the sidelines for much longer and will have to work out new ways to trim the energy consumption of the machines they build.
This growing energy awareness was on display throughout this week’s Hannover Fair, where major suppliers and users of motion control and automation equipment showcased their energy-reduction strategies and technologies. The fair also itself featured brand new energy-efficiency displays, including an “Energy Tunnel” exhibit that highlighted ways to make common industrial processes — like pumping — more efficient.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
