Detroit—Keeping passengers cool in the 2001 PT Cruiser was a design challenge involving efficiency. The 2.4-liter four-cylinder engine taking up only 148.2 inch3 total volume necessitated designing a special air conditioning accumulator that would fit into a confined area.
The accumulator from Parker Hannifin Corp. (Lyon, NY) uses a patented helix design that improves oil circulation. "The helix design provides a swirling and stirring motion that helps keep the oil and refrigerant mixture consistent," says Cary Horamoto, engineering manager of Parker Hannifin's refrigeration and air conditioning division. Keeping the mixture consistent reduces the amount of oil needed for charging the system, creating a cost savings for DaimlerChrysler.
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.
