I spent a month last year in the underdeveloped country of Namibia. Residents were proud to tell me that Namibia is the only country in the world that has a constitution that embraces environmental sustainability.To Namibians, it was a recognition that protection of theirs materials resources was critical to their future. Since I’ve returned to the US, however, it’s become clear that the concept of sustainability, and specifically, sustainable design, will soon become important to us as well.
One specific issue I want to focus on is use of renewable resources as a feedstock for polymers. The immediate reason isn’t really environmental, at least for design engineers. Unstable oil supplies triggered massive runups in plastics prices two years ago. Today it makes sense to study the potential of corn-based polymers for mechanical design projects. Sound crazy? At the giant plastics fair in Germany this fall (K 2007), DuPont plans to present technical data on new grades of Sorona and Hytrel that are corn based. Stay tuned.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
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.
