Recent Developments in Permanent Magnet Gear Systems & Machines
Last month I attended the Magnetics 2010 Conference in Florida, where a variety of speakers gave updates on the business and technical side of the magnetics industry. One of these days I’ll actually write up my thoughts on the conference itself, probably in conjunction with my RareMetalBlog parter in crime, Ian London. In the meantime, however, [...]

Wednesday, February 10, 2010
In 1984, the magnetic materials research community in Europe was at a formidable crossroads. The latter part of 1983 had seen industrial research groups in the USA and Japan simultaneously announce the discovery of a promising new permanent magnet material, based on the neodymium-iron-boron [Nd-Fe-B] alloy system. This long-sought successor to the ever more expensive [...]

Thursday, January 14, 2010
You may recall an article I wrote late last year on Correlated Magnetics Research, a company from Alabama who has created and produced what they were calling “programmable” magnets. Since then, I’ve had the chance to play with a number of their prototypes. I had initially been a little confused as to what the technology was [...]

Sunday, December 13, 2009
Siemens reported recently on an interesting use of magnets for the harvesting of fast-growing algae that will eventually be turned into biofuels. The use of algae as a potential source of fuels is nothing new within the world of renewable energy. As Siemens says: Algae are a valuable source of raw material. For millions of years throughout [...]

Thursday, December 3, 2009
Earlier today, my colleagues at Dexter Magnetic Technologies announced the launch of an innovative downhole generator tool, which we have developed for some pretty extreme drilling conditions. This new high pressure – high temperature (HPHT) tool could lead the way to drilling deeper and more productive oil, gas and geothermal wells in the world’s most demanding drilling environments. The tool was [...]

Monday, November 30, 2009
Last week, a technical consulting company called Ricardo, based in the UK, issued a press release on its Kinergy concept for a “high-speed, hermetically-sealed flywheel energy storage system concept with a highly innovative and patented magnetic gearing and coupling mechanism“. What immediately drew my attention to the concept, is the use of a permanent magnet [...]

Sunday, November 22, 2009
[Updated: 03/09/10 & 11/23/09.] The Times Online has just published a story on a technology that apparently “has the potential to revolutionise the renewable energy industry by making wind power cheaper and more reliable and greatly increasing the efficiency of wind turbines for electricity companies.” The driver behind the work, conducted by Dr Markus Mueller and Dr. [...]

Friday, November 20, 2009
Earlier today, Science Daily published an article on the use of magnets by a researcher at NIST, Javier Atencia, to create a “new, inexpensive, reusable and highly efficient microfluidic connector“. Microfluidics involves the control of fluids in very small channels and containers. According to the article: The NIST connector employs a ring magnet with a O-ring gasket [...]

Monday, November 16, 2009
Over the past few days, Australia’s ABC Radio National broadcast not one, but two items on rare earth metals, to both of which I heartily recommend listening. The first item was broadcast on the Breakfast program on Friday, and lasts a little over 6 minutes. It’s an introductory piece on the subject, but spends significant time discussing [...]

Saturday, November 14, 2009
My thanks to RareMetalBlog’s Ian London for pointing this article out: Oct. 27, 2009 – by Tracey Bryant – The University of Delaware has won a $4.4 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency (ARPA-E) to lead a multidisciplinary, multi-institutional research project to develop the next generation of high-performance permanent magnets. Stronger [...]
