Environmental arguments aside, the weak link in the electric car story might be a soft metal called neodymium. You may have heard of Nd:YAG lasers. The Nd stands for neodymium. Another major use is in permanent magnets, such as those used in electric cars. China controls most neodymium production and is now restricting exports and boosting tariffs. As a result of China’s actions and demand from electric car makers, neodymium prices are now close to $90/kg, up from $19.12 in 2009.
Efforts to find new global sources for the metal are accelerating. A Japanese joint venture will look for neodymium in Vietnam. An article in the Denver Post says there is a new “gold rush” for rare earth metals such as neodymium in Colorado and other Western states.
And not surprisingly, engineers are at work trying to improve the performance of induction motors in which magnetism is created by applying an electrical charge. The problem with induction motors is their poor efficiency and their large size compared to motors using permanent magnets. Continental AG, the largest noncaptive electric motor supplier for autos, is also working on alternative technical solutions.
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
