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.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
