Laptop Fires On Airplanes

The risk posed by lithium batteries on airplanes is not exactly new news to this community; but the issue is starting to get wider exposure. Reader Maximum Prophet points out that as usual xkcd gets it right, and sends in an NY Times article calling the batteries a fire risk that clears security. "More than half of the 22 battery fires in the cabin of passenger planes since 1999 have been in the last three years. One air safety expert suggested that these devices might be 'the last unrestricted fire hazard' people can bring on airplanes."

Mystbusters will also film an episode where they Confirm the "Exploding Laptop Battery" myth... the episode will when a laptop battery they stuffed with 11 pounds of C4, rolled in a coating of thermite, and dipped in ball bearings is used to destroy 4 decomissioned planes somewhere in the middle of the desert.

    This ban will affect laptops, portable game systems, video players, etc... the things you actually use during the flight. You'll have to remove your battery at the ticket counter, and your airline will give it to TSA to put in a special fireproof container for the duration of the flight.

    The airlines come in and say "We're on your side, travellers" and begin to retrofit planes with power outlets at the seats. Ticket prices will increase slightly to help cover this retrofitting on behalf of all travellers.

    Of course, 110v will be "too dangerous" and 12V cigarette lighters will be "too big to fit", even though both would allow you to use things you probably already have in your laptop bag.

    Instead, they fit the planes with 8.23 V outlets which require a special 103, 72, or 45.8 degree angle doohicky (depending on the aircraft manufacturer) with three and a half prongs, which is now the special "Saf-T-FlitePower" plug.

Dell will add one to your laptop for $250 if you check the correct box on the 8th tab while building it online, but it's ok, because 67% of the time the box will magically be checked by default (people who didn't mean to get one will wonder WTF this this with 3.5 plugs is when they open their UPS box and it will ride around in their laptop bag unused for 4 years).

    Now, when you're on the plane, your outlet will be disabled, and it will take the flight attendant typing in a special code with your seat number to turn it on. You can buy one of these codes with your ticket, or may get one automatically if you purchase a certain fare class, and the reason for the whole thing is to cover the cost of the retrofitting (nevermind that they already increased the base cost of the ticket to help cover this, and the functionality which allows them to turn off individual outlets quadrupled the cost of the retrofit in the first place). Also, please be patient while the flight attendant enters your code... for safety reasons this has to be done after reaching cruising altitude, so on some flights you may be halfway through the flight before you even get power. (No kidding, if you've ever been on Frontier and gotten a DirecTV access code).

    Once you get off the plane, you'll travel down to the baggage claim, where an avalanche of special fireproof containers will come tumbling down the little ramp. Have fun sorting them out with everyone else on the flight who had to check their battery.

    Of course, those of us who don't check bags (I haven't checked a bag in over 10 years and fly 4 segments a week), will just be screwed, but luckily the SkyMall catalog will start selling a cool new device which allows you to pedal up some power for your laptop while in flight!

    Li-Ion batteries are some of the highest energy-density storage devices available to the general public. As such, they *are* dangerous. I design battery packs for a living, and let me tell you - if not for microprocessors and safety circuits, we wouldn't use Li-Ion batteries.

    They are the only batteries that I know of that can fail dangerously when over-discharged. You start creating internal shorts of lithium whiskers between the cathode and anode, which bypasses any cell safety circuits.
    They go boom very spectacularly if you overcharge them. The model RC heli folks have found this out the hard way, as they tend to run bare cells without protection circuits to save weight. (http://www.youtube.com/watch?v=hcwOwf55Rtc).
    They have very low internal resistance, which means in a short circuit, they can release energy very quickly. Every manufacturing engineer at the company I work at have welded calipers to cell tabs, from accidentally touching the wrong stuff while taking measurements.

    For a good cell manufacturer - and I'm talking about the LiShens, Sanyos, Kokams, and Panasonics of the world, the failure rate is 1 in 1 million. It's just a fact of life. The fly-by-night operations in China, responsible for some of the god-awful counterfeit cells out there, god knows what those failure rates are. And the vendors who use these cells tends to not put in the safety features (look up a BQ20Z70 chip, for example) to make a failure more likely.

    The nightmare scenario would be some dude getting some last minute work in at the terminal, plugging the battery in for charging. Then the plane takes off with the laptop in the overhead compartment where the oxygen lines for the safety masks are kept, and the cells let go. Judging from how much energy a single 18650 cell can contain, it could easily do some very serious damage.

    With the prices on Li-Ion dropping and more devices using them, it's no wonder that almost all of the 22 incidents reported occured in the last 3 years. Still a small number considering the amount of airplanes in the air at any given time, but enough for someone to pause and think...
