Thanks, I was wondering how Boeing came out on that. Interesting that the Japanese gov't came out on the side on the battery mfg, Yausa. I assume this was a bid deal for Boeing , saving weight if it worked and getting a new battery engineer if it didn't.

Probably. There are a several thousand laptop size lithium batteries packed in a tight space. If one has a problem, gets too hot and ignites, it can set adjacent batteries off too. If the battery shorts, it can also put a high current load on the other batteries.

In the case of the 787, one cell failed and overheated. This set off some of the adjacent cells. Part of the battery fix is to put more space between the cells and improve/increase the material that separates them to reduce the chances of a cascade if one cell fails.

BTW, on electric powered cars, fire departments require special training on each model so they know where they can and (more importantly) cannot cut into the car or apply the "jaws of life" to avoid damaging the battery and/or electrocuting themselves.

If you have an electric car and get into an accident (even one you can drive away from) you need to keep an eye on the car for awhile afterward to make sure that the battery was not damaged. Damage to the battery usually manifests itself when the car catches fire.

A friend of mine got one of these recently. All I had to do was mention it (after having read about it here), and the lure of it was just too powerful Laughing I (just barely) managed to resist.

I'll try to remember to update the thread if he has any comments about it as time goes by. It is pretty nifty looking, and has connector/adaptors for iGoodie charging and etc.

One thing I wonder about: Seems that in order to have it on hand and ready to go if needed for car starting, that one would store it in the car charged up and ready to go. However, I have read that heat is hard on fully-charged lithium batteries - it was recommended that if one had to store one's laptop, for example, in a warm or hot car, to purposely have the lithium battery at about 50% charge. Fully charged the heat would be more detrimental to the battery.

I don't know if this would apply to the product here, and/or if there is anything to protect against it; but I could sure see storing it fully charged in a warm/hot car.

Yes, I am involved infrequently with this in my local area as an EMS member with our local FD.
It is important to know what you are driving (gasoline, diesel, electric or combo)
and the hazards your specific vehicle poses if you have a collision requiring assistance.

Aside from knowing your vehicle, knowledge of your personal medical info, if you cannot speak for yourself,
is of great significance in assisting you in case of an accident.

Think about this:

for yourself and loved ones. It's a great gift for those you care about.

Aye.

The yellow dot sticker/book sounds like a good idea. I had not heard of it before--and not sure if our local EMT/Sheriff's department knows of it either.

However, I do suggest that everyone who has any significant medical problems, put a laminated card in their wallet right next to the driver's license. We have two sided, with small print--cheap and easy to make on your computer. It has contact information, Primary care physician, medications currently taken and medical history.

The first place an EMS/ ER personal or LEO will look is in the wallet for information.

WE also have a notation on our phone's contact basis, where the medical information/history is located on the cell phone (smart phone) memory.

Better than Bob's laminated card and the Yellow Dot (the dot is a yellow
sticker placed on your car's rear window) is a credit card size ID with
a QR code, which can be read by any smartphone, bringing up a webpage
containing all owners medical information.

Other benefits included in this emergency 911 medical information system
*immediate significant medical information on card, used defined
*other stickers for car, kids lunch box, etc
*color photo ID
*emergency contact information
*GPS mapping of the incident site
*online personal medical record keeping system
*less than $15./year

Check it out here:

www.myinfo911.com

This speaks for you in case you can't. And, like money in savings
account, you may not know when you need it, but when you do,
you're mighty glad it's there.

Aye.
