Lithium-Ion Batteries Emerge as Possible Culprit in Dreamliner Incidents
Auxiliary power batteries onboard a Japan Airlines Dreamliner 787 caught fire at Boston's Logan Airport on January 7. The battery was taken back to the National Transportation Safety Board's Materials Laboratory in Washington for further examination. (Source: NTSB)
It's interesting that this is the same technology that Ford just standardized on. While the article mentions the cooling systems used in autos and some of the other design components, I can't help but wonder what can happen a few years down the road in vehicles that are not properly maintained...whatever the definition of "properly" may be with respect to battery safety.
I agree, Al. The spotlight is very bright in this case. I initially wondered if the bright spotlight might be part of the problem here. But the succession of battery overheating incidents in January alone is hard to ignore.
Chuck, Very interesting report. It's amazing how with a system as complex as the Dreamliner, there are a very large number of unknown variables to resolve. Tough for the Boeing engineers who are moving a project of this scope into the marketplace, especially in a spotlight as bright as this situation.
They obviously overlooked the battery design slightly in the initial stages of development. At least no one was hurt, but I am sure Boeing will fire a few on the battery team. With all the battery exploding incidents from the past, I am surprised that wasn't a concern for the engineering team. However, it could have been a manufacturing error.. Time will tell.
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.
