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.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
