    From a distance, it looks almost like the 767- 200ER. Its cabin is about a foot wider than the 767.

    The forthcoming "stretched" version, the 787-9, probably won't look so chubby. It'll look more like the 767-300.

    It is all integration issues.

    Someone forgot to check what happens to the electrical system when XYZ happens.


    XYZ happens, you get batteries on fire. :P

    batteries are just the N-th problem in a parade of issues

    Right now it's speculated that some of the other problems with the 787 might be because of outsourcing so many component systems. It's not just Boeing doing it; it's become more prevalent in the industry.

    But it seems that the battery problems are the batteries themselves, not the electrical system. They don't know if it's a design flaw, or a manufacturing defect.

    The Li-ion battery is more complicated to make, and is prone to overheat.

    There have been problems in the past, including aviation. Fires in airplane cargo holds from overheating computer batteries led to a limit in transport. Dell and Apple had recalls around 2005 for laptop batteries.

    The only thing worse than a fire in an airplane is a fire in a submarine. A few years ago, a US Navy SEAL mini-sub was charging Li-ion batteries in port when one exploded, starting a fire that took hours to put out. Luckily, no one was aboard.

    Li-ion has big advantages over Ni-MH - less weight, more power capacity, faster charging, no charge memory, very low passive discharge. Supposedly, the technology as to safety has advanced, so the FAA gave Boeing permission to use the batteries in the 787.

    GS Yuasa Corporation (supplier for the 787):
    The rugged prismatic sealed battery design is capable of withstanding extreme operating conditions far greater than those normally seen in commercial aircraft operation and requires absolutely no maintenance. Large lithium ion technology offers superior performance and safety under any conceivable operating or storage condition.
