Safety authorities to hold hearings into Boeing 787's battery woes

So the point of the battery is to save fuel by not running the APU. So wouldn't the easy solution be pull the battery and run the APU? That way the planes can fly.

Re: NiMH

Or they could simply use Lithium Iron Phosphate. The Lithium Cobalt Manganese batteries they use are the same chemistry as those infamous exploding laptop batteries. LiFePO4 don't suffer from thermal runaway like the Lithium Cobalt do, and they don't generate their own oxygen either. Not sure why Boeing went with a much less safe battery chemistry, when the energy density difference between Lithium Cobalt and Lithium Iron is only a few percent.

Never fired up

Due to the fact that pulse jets run extremely hot (see the video link sent above) and the fact that there is no blue on that metal, I think it's safe to assume this puppy has never been fired up.

Which begs the second question: Do you need to wear one of those shiny silver thermo suits to ride it?
