March 20, 2012 8:24 am | News | Comments

High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories. The simulations show the release of output energy that was many times greater than the energy fed into the container's liner.

Polycrystalline diamond drill bits open up options for geothermal energy

March 19, 2012 5:40 am | News | Comments

Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact (PDC) bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling. Sandia National Laboratories and the U.S. Navy recently brought the technology fullcircle, showing how geothermal drillers might use the original PDC technology, incorporating decades of subsequent improvements by the oil and gas industry.
