Ever wonder what happened to BigBelly, the solar-powered trash compactor created with help from an array of design tools, including SolidWorks? Well, BigBelly is now a big hit in cities in over 40 states, the most recent to sing its praises-the city of Philadelphia, which aims to save over $13 million over 10 years deploying 500 BigBelly units to cut collection costs by 70%. If you want a closer look at how BigBelly works-and a peak at the inner workings of all of the electronics–check out this video, which peels back the covers on the unit.
BigBelly’s design concept was to refashion a standard trash compactor into a solar unit. While simplistic in concept, it involved some significant rethinking of the design to minimize energy consumption to keep the units self-contained and relatively small in stature. Using the 3-D tools, the design team created a drive chain mechanism to power the compaction system, which uses no hydraulic fluids and consumes minimal energy. There are also microprocessors and sensors to help determine when the trash needs to be compacted and collected and even a Web portal to allow city customers to monitor the status of their units.
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.
