FAA Grounds all 787s

[fusionTX]

The use of new battery technology is among the cost-saving features of the 787, which Boeing says burns 20 percent less fuel than rival jetliners using older technology.

 

Lithium-ion batteries can catch fire if they are overcharged and, once alight, they are difficult to put out as the chemicals produce oxygen, Boeing's chief engineer for the 787, Mike Sinnett, told reporters last week. He said lithium-ion was not the only battery choice, but "it was the right choice".

I'm confident that Ford has done their homework on batteries and that their hybrid system has all the safeguards needed to prevent any problem with the lithium-ion.

Since its conception, I feel Boeing has made more wrong than right decisions with the 787. The original drawings that were shown to the airlines were influenced more by their marketing department than their engineering. This resulted in a very unique looking aircraft that boosted sales, but by the time engineering realities were applied, there is little to set the 787 apart from others when it comes to looks. The 787 applies too many technology changes into one original airframe, which has proven in the past (and present with the F-35) to be a forumla for trouble. I feel no one at Boeing had the guts to say "No, we can't (shouldn't) do it that way in that amount of time".

With proper cooling and monitoring, maintaining between 40 and 80% charge, the Lion packs will last a VERY long time. But discharge, or overcharge them once time, and toss them away or you risk a fire. Lion are much much safer than LiPo packs though. Damage the packaging on a Lipo, RUN!

With all the orange convoluted wire coverings and orange striped tape in this car I acquainted myself with the High Voltage Service Disconnect right away.

These cars do a lot of interesting things and a collision and 'hard physical jolt' causes things to happen.

 

A question for acdii and the 2010FFH accident.

First, I'm happy to hear that you and your family are basically okay and the car is being repaired.

Question(s): Did the (I love this new terminology) non-trivial collision event cause the fuel or batteries to shutoff?

Did a simple re-start get the car going again?

It didnt hit hard enough to trigger any of the kill switches. Just enough to jolt us, and break the wheel bearing. I was only going between 15 and 20.
