    I was only responding to the person who said that the planes that burst into flame need to be used only by Conservatives.

    I have a feeling that if these planes were being assembled in the new Boeing Plant, we'd have heard about it pretty clearly from all of the union supporters in the country.

    All I can think is bleed air being taken off of the compressor section in a turbine but those systems are generally used for cabin pressurization and environmental applications.

    They are highly effective and don't represent a profound amount of weight.
    Boeing approach on the 787 was to combined as many weight eliminating technologies as possible to a relatively large net gain. They also claim better efficiency using electrical systems for a fuels savings. Exactly how effective they are in practice is still in question, especially considering that Airbus has chosen to stick with bleed air systems.

    Bleed air for what ? Be specific. Airplanes have been using batteries for decades.

    The difference is the new Lithium Ion Batteries and the push to make the thing greener.

    The electrolyte materials in aa lithium ion battery are FLAMMABLE.

    So the bigger the lithium ion batyery the bigger the chance for a fire.

    They're are not practicle in large applications.
