When the term “wind turbine” comes to mind, you usually think of hulking goliaths that dominate the landscape. And in fact, as I wrote about last November, there is a dramatic trend toward large wine turbines that generate more electricity. At the same time though, turbines with seven-feet-long blades are popping up on the tops of office and apartment buildings in Michigan, and elsewhere. Tom Huff, an urban developer, put one of the mini turbines on top of a 10-story building he was renovating in Kalamazoo, MI. The turbine needs winds of at least 8 mph to generate electricity, and under optimal conditions, could generate 2,000 kilowatt-hours a year. Huff figure he will recover the cost of the turbine in five years with the help of a significant federal tax credit. The average installed cost of the Swift Turbine is $10,000 to $12,000.
Huff’s turbine was manufactured in nearby Grand Rapids by Cascade Engineering, which invested in a business that developed the turbine called Renewable Devices Swift Turbines Ltd. of Edinburgh, Scotland. Cascade made the investment after discovering it could reduce the cost by injection molding a rotor, which previously had been manufactured with a labor intensive process using expensive carbon fiber. Cascade now makes the rotors and distributes the turbines.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
The 100-percent solar-powered Solar Impulse plane flies on a piloted, cross-country flight this summer over the US as a prelude to the longer, round-the-world flight by its successor aircraft planned for 2015.
GE Aviation expects to chop off about 25 percent of the total 3D printing time of metallic production components for its LEAP Turbofan engine, using in-process inspection. That's pretty amazing, considering how slow additive manufacturing (AM) build times usually are.
A $1,500, hand-operated, bench-model, plastic injection machine crowdsource-funded via Kickstarter can be used to mold small, quality, plastic parts inexpensively, on demand.
The federal government is launching competitions to kickstart three more manufacturing innovation institutes, including one focused on Lightweight and Modern Metals Manufacturing Innovation.

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 radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
