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 firstname.lastname@example.org.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
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.
