A partnership of German electricity and natural gas utilities has begun operating a 200 kW fuel cell plant that uses pure hydrogen to produce power. The Hamburg utilities purchased the unit from ONSI Corp., South Windsor, CT. The unit is similar to the company's model PC25 commercial fuel cell power plant, except it does not contain fuel processing equipment for extracting hydrogen from other sources, such as natural gas, propane, or methane. This means the new fuel cell must be supplied with pure hydrogen, although the plant operates more efficiently for it. Similar to a battery, fuel cells convert chemical energy into electricity and hot water. The difference is that the chemistry is relatively clean, and produces only water and carbon dioxide as waste. The Hamburg unit is so clean, it was installed adjacent to an apartment building that will use the hot water generated by the fuel cell to heat the building. ONSI currently is manufacturing one 200 kW commercial fuel cell plant every week. For more information, contact Michael London, ONSI, at (203) 261-1549.
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.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
