Magnets, Algae and Biofuels

Magnets, Algae and Biofuels

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 [...]

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

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 [...]
