Flaming Cellphones
phorm writes "Many of us have heard the urban legend of cellphones causing fires at the gas pump, but how about the hazards of replacement batteries? Reuters is carrying a story about a woman whose cellphone burst into flame, causing her superficial burn injuries. According to Nokia, the problem has occured before, and is related to non-brand replacement batteries. For various reasons, these batteries may overheat and catch fire, or even explode! So far I haven't found much info on whether this has happened with other brands of phone, though I do know that my little flip-phone gets very hot when running in analog mode. Perhaps some slashdot readers have had a similar experience?"
I worked with some people who were simulating battery-powered electronics. The program had an error message of "Device is on fire". People would call up the tech support for the simulator and ask what the error message means (perhaps they thought it was like Guru Meditation errors or something equally geek-funny). It meant, literally, that the simulated battery is on fire.
;)
The battery controller is in the phone, not the battery, so if it doesn't get the battery it expects to get, there's no limit to the pyromaniac fun that can be had.

to quote from page 12...
Don't use the phone at a refueling point. Don't use near fuel or chemicals.

I could see this being true, but I could just as easily see it as a story planted by the phone manufacturer for one of two purposes:
Those of us salivating all over the Samsung SPH-i500 PalmPDA/phone (units of which finally started trickling to market 3 weeks ago) have been hearing for weeks of the travails of this guy who's modded his to add Bluetooth and maybe more.
"I decided to build the sled out of the extended battery. Initially, I was planning on making the standard battery fit inside the extended case, but then I got a first hand lesson in the volitile nature of li-ion batteries. After the 2 FOOT FLAME, which looked like a smoke flare going off, this MESS is what was left of the battery ... What caused that? Believe it or not, it was LIGHTLY nicking it with the tip of my jewlers screwdriver! It doesn't take much."

The complete story is here; the flames start on page 2.
"Hello, Samsung? I would like 1000 units of your new Lithium-Ion bomb phone please. Do you ship to Chechnya?"
One simple rule for its versus it's
Any practical electric car will use fuel cells anyway, so told who so?
And the fuel cells do what with fuel? Provide a large power supply with little internal resistance, as is required to run the large loads of electric motors to drive the wheels. What do *you* think will happen when the wires or bus bars between the fuel cells and anything else get crimped during a car accident?
Never mind that fuel cells run on combustible fuel which must be brought into close proximity to the soon-to-be-glowing-red-hot output terminals of the car accident fuel cell. At least in conventional cars, the only statistically significant source of fuel ignition is sparking from randomly bent metal scraping on asphalt. Of course, you'll still have that, too - unless your fuel cell car is an Adobe. (Old SNL reference, all you Gen-Y types won't get it.)
Of course, this means that fuel cells will actually be practical. Given the notorious sensitivity of their osmotic membranes the sort of fuel contamination which passes right through most filtration devices, I can't imagine that you'll be filling your car up off too many gas station tanks.
