Boeing Dreamliner


There's an interesting pdf here from Boeing about the Dreamliner battery problem which now seems to have been resolved. Essentially Boeing appear to have made a range of improvements to the battery itself, changed the charging system and put the battery in a stainless steel box vented outside the aircraft.

The faulty battery was quite a mess judging from the picture below, taken from Boeing's pdf. It's not a process with which I'm familiar, but Boeing seem to have been pretty upfront about the episode.

Possibly better to stick to boats. They don't plummet when the battery goes pair shaped.

James - dry land is even safer (:

An old draughtsman told me:- If in doubt, make it stout, out of things you know about.

Snag is no-one really knows about lithium batteries. I await the upcoming electric racing car races with interest, it will either be very boring or rather too interesting.

Roger - you are right, nobody really knows about lithium batteries. The Nissan Leaf uses lithium so I wouldn't touch it - quite apart from the range.
