Sending troops into foreign lands with superior technology gives them an edge against hostile aggressors and terrorists. However, the latest pieces of technology—laser range finders, global positioning systems, and imaging displays—are worthless if they run out of electrical power. Bigger batteries are not the solution: The bigger the batteries, the heavier the soldier's pack becomes. That's why Ed Baker, a project manager at Pacific Northwest National Labs, is helping develop a new power generator that weighs approximately one-tenth of what lithium batteries would weigh if required to produce the same amount of electrical power. "Our system produces the hydrogen that fuel cells need to create power," says Baker. The power generator's fuel processor consists of a combustor, vaporizer, primary conversions reactor, and a gas clean-up device. A proprietary catalyst produces hydrogen from hydro-carbon fuels. Reactions take place in a catalytic converter. For more information, send e-mails to email@example.com.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
