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.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
