New Downhole Permanent Magnet Generator Tool For Extreme Oil, Gas & Geothermal Drilling
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 [...]

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 [...]

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 [...]

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 [...]
