OT: Something Doesn't Ring True Here

From a recent news article:
"The lawsuit, filed in Cincinnati on Wednesday, claims the iPod Touch
(16GB) exploded while inside the 15-year-old boy's pants pocket. The
boy was sitting at his desk in school, the document says, when he
"heard a loud pop and immediately felt a burning sensation on his
leg." When he stood up, the suit says, he realized the device was on
fire. "  Supposedly, the boy received second degree burns and tons of
mental anguish.

I can't imagine a device such as an iPod Touch exploding and catching
on fire while in a pocket.  It just doesn't seem possible.  What was
the source of the energy potent enough to explode and start a fire.
The battery?  I doubt it.  The electronics?  Nope.  Other ideas?

Lithium ion batteries store a *lot* of energy which can release some
spectacular pyrotechnics as in those cell phone and laptop fires a
while back. Google 'Ipod fires'.

There has been at least one death reported due to a cellphone
battery pack overheating and exploding. There was a recent
news story on the incident (Asian, I believe.)  A piece of the
exploding material cut the man's jugular. There have been
numerous stories on the dangers of using cheap imported
batteries that were made with poor quality control.

I would be skeptical too if it hadn't happened to me.
A while back I had a new LiIon battery sitting on my
desk. We were planning to use it as a memory back
up supply in an instrument we were designing.

Just sitting there, not accidentally shorted out, it
started smoking and the plastic wrapping melted
and came very close to catching fire! The manufacturer
said it was caused by an internal short, and was
a very rare occurance. Not rare enough for me!

I agree what that! I have, sitting before me, a Duracell MN1604 9V
alkaline battery that was in my bedside clock for 'standby' power. One
of the AAAA cells must have shorted internally and exploded by firing
the casing and guts through the bottom of the battery and across the
inside of the clock case where it dented the inside of the hardwood
case. Luckily, the bare cell casing did not fall on any circuits and
short things out.

I also have an AA NiMH that did as you describe inside my digital
camera,  melting and splitting the plastic cell wrapper and slightly
distorting the battery compartment walls. It must have been,
fortunately, not fully charged when it shorted out so there was not
the full energy available to do damage.

So, it seems that all cell technology in common use is prone to this
type of failure.

On a similar subject, a reminder to anyone who owns a Maytag, Jenn-
Air, Amana, Admiral, Crosley, Magic Chef or Performa refrigerator to
check the Maytag web site to see if that model has been recalled due
to the control relay potentially catching fire. There are about 1.6
million affected units and 41 reported cases of fires.

Exactamungo! I'll be driving a model A Ford, and
passing all of those hybrid & electric time bombs on the freeway.
At a blazing 35 mph of course.  ;-)

Er... might I point out that a gasoline car has a certain quantity of
highly flammable fuel on board that has a long, long track record of
car fires? Me, I drive a diesel. :)

In Arizona, they passed a law that school buses cannot be gasoline
powered because of the fire hazard.  They have to be diesel,

  Absolutely 100% possible. These batteries have enormous energy
capacity for their size and it can be released ***ly under specific
conditions. The batteries are supposed to have built-in current limiting
that prevents this from happening if they are shorted but statistically,
there are going to be a few batteries where that circuitry fails out of
the billions that are produced every year.

I had a 9V cell sitting on a table near me and it touched my keys. I
noticed the problem when it blew the bottom of the battery right out
and it flew across the room.

   Isn't the Model A the one where you sit on top the
gas tank? :)

No, it's right in front of you.  The filler cap's in the middle of the
panel that separates the engine compartment from the
windshield--whatever that's called--as in this pristine example:
<http://local.aaca.org/tucson/images/other/DSC05542.JPG>

The round chrome thingie is the filler cap.  Does suggest a different
interpretation of the term 'firewall'....

Surely that cylinderical red thing by the front bumper is indicative
of something to do with this thread!
