This month the Clinton Global Initiative hosted CGI America, an annual event that highlights ways to boost U.S. economic recovery, and much emphasis was on STEM education.

The subcommittee’s investigations revealed that the nation’s manufacturers are at a disadvantage when it comes to minimizing the effects of high U.S. corporate taxes. Read more
As everyone from defense contractors to hobby enthusiasts explore the possibilities of additive manufacturing (AM) technology (popularly known as 3D printing), the question must be asked: with its seemingly endless applications, is it the answer to all things manufacturing related? Is it truly a panacea, or “just another tool in our manufacturing toolbox,” as Tim Caffrey, an associate with Wohler Associates, suggests? Read more
Earlier this month, IMT examined the nature of the mandatory federal budget cuts known as sequestration and how they were likely to affect U.S. manufacturing. A second article looked at how some of the largest contractors were coping with the cuts. Here, IMT outlines the fallout on small companies in the defense contractor supply chain. Read more

The company wouldn’t give me details on the generator, except to say that it’s not piezoelectric. Based on the diagram below, it looks like a rack-and-pinion that drives a small permanent magnet generator. Read more
