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.
HP's industry-changing 3D printing announcement for commercial-scale end-production wasn't the only news of note at RAPID 2016 this week. Here are six more game-changing software and hardware news items, plus some videos explaining HP's technology.
HP has launched its long-heralded Multi Jet Fusion 3D printing technology for commercial-scale end-production, plus an ecosystem to go with it. The package could change the entire industrial market for making end-products with additive manufacturing. At the very least, it will be game-changing.
Nearly all the products in this latest crop of new adhesives target electronic and other components for consumer electronics and automotive assemblies. Some are alternatives to liquid adhesives, others are liquids that cure faster, and several stick well to multiple substrate materials.
