Obvious solution to make Note 7's 'safe' for transport?

You totally misunderstand. This is simply about the idea that if the battery is fully discharged, it makes it impossible for the battery and phone to self-immolate.

Now we're getting close. Later, when I get a chance, I'll figure out how much energy that 5% represents. Probably in Joules. That should give us an idea of how much heat that could generate in the process of being dissipated in the battery cell itself.
Well I can see this discussion as an interesting theoretical debate, but I was under the impression you were advocating for the FAA to allow discharged Note 7's onto airplanes.
Do bear in mind though that, once the battery is on fire, you're looking at a totally different chemical reaction (and certainly not something they account for when determining the capacity of a battery
). The 5% of charge only has to be enough to trigger the actual combustion.

Personally.. I Don't Even See How This Is Still Even A Discussion..Would you give your infant a fully unloaded Glock to snuggle?
Theoretically, you are absolutely correct. Without a charge, there is no possibility of the ignition source being the battery.
Technically, even discharging a partially charged Li-Ion cell it to discharge it could generate enough heat to ignite.
Statistically, it's highly unlikely that ANY note 7 is going to spontaneously ignite, regardless of charge. How many phones actually caught fire?
Out of the 1,000,000 sold in the U.S. that's a 1:10,000 chance. And that's with NO due diligence.
Practically, I'm not sure there is a way to measure a complete discharge without removing the battery. Assuming that the battery is completely discharged just because it won't boot the phone is probably not true. What they haven't said is exactly how much of a charge is necessary to ignite one of these things.
You take this device into an open area.. Pray for "Non-Combustion" .. Do a factory reset.. Place said device in a metal container.. Transport said container to your nearest carrier's location.. And.. get your $950.00 back.
End of discussion.
It's a "Fail".. Live with it.

Is that the motto for being with a woman of questionable reputation for the evening when you go pee the next morning?
That was a low blow. Doesn't burn though.

Hey, great minds think alike, right??
I'm still loving my Note 7! I just recently got two of the Samsung clip on wireless charging battery packs - 3100mAh each, for $15 each! Now I can have extra power readily available if I ever run low and am not near an outlet. I also bought a wireless charging pad for my desk at work, and for my windshield mount in the car. Now I feel good that I won't physically wear the USB port hardware out with plugging in the charging cable a million times a day.I'm still keeping my eyes and ears peeled for further information out of Samsung about any more findings on the cause of the meltdowns. I also felt some validation for my hypothesis/question that I started this thread with, when I read that Samsung is once again saying they're rolling out the 60% battery charge cap update to all the devices still out in the field in Europe. It says right in the information it's designed to limit the amount heat that can result from the battery failing. I'm still willing to bet money that a 'fully' discharged battery, at least, discharged enough so that the device will no longer power on, is for all practical purposes inert at that point.
I've continued to try and imagine ideas for how the meltdown problems arose. I have to assume they are thinking of all these things too, but here's some questions I'd have. Seeing as simply using a different battery manufacturer didn't appear to cover the issue, how else could the battery be compromised, in a way that fits the observations? Do they have any records that allow them to trace back manufacturing and assembly activities by IMEI? If so, the IMEI of each phone that failed and was reported could tell them if there was a particular piece of assembly gear or location that correlates, or a person or shift of assembly workers that correlate. Also, if there is any large number of new but uninstalled batteries still sitting somewhere, did they carry out an inspection of them, like measuring their dimensions, checking their weight, and scrutinizing them all for any appearances of anomalies? What if, regardless of which battery manufacture was used, some of the batteries from each were just slightly larger in one or more of their dimensions than they were supposed to be, and that resulted in those batteries being jammed too tightly inside the device? And then, the battery was deformed by that just enough to then direct short out, internally, soon afterwards? Or, was there some shift worker that didn't operate an assembly machine properly, and occasionally slightly damaged some batteries during each shift? Where all the phones assembled in one factory, or multiple ones? Were some batteries slightly damaged during shipping to the factory, like say, if they were the ones in the bottom of a pallet, and the forklift force that lifted the boxes impacted them slightly, but not all the others? I could keep on thinking of all kinds of possibilities. It seems like there could easily be an explanation that results in saying that only some devices would have ended up with the lurking problem, and many more wouldn't have. I know there's probably no comfortable way after the fact, with millions already out the door, to identify specific devices believed to be at risk verses any that aren't. And so, Samsung just ran for the exit to try and get out of the mess as quickly for itself as it could. Kind of like chewing off its leg in a trap, rather than taking the time to figure out how the trap operated and getting it open, to save as much of the leg as they could.
I just received one of those fancy "fireproof" boxes to ship back my Note 7 
I called Samsung and told them that I'd turned it in a month ago, and they advised me to call Sam's Club and determine the phone's disposition, since Samsung still thinks I possess the phone. I called Sam's and they said that all Note 7s turned in are still there, waiting for the appropriate shipping materials - they can't get rid of the things!
EDIT: I think it's humorous that Samsung included surgical gloves in the box, presumably so we don't have to contact the same Note 7 we've been handling since we got the thing. I guess the recall causes phone cooties or something

Great!! Ask them if you can have yours back!
No thanks. The Note 8 is right around the corner and I can wait. I passed an Army-Navy Surplus store in Nashville today, and the sign out front said "We have better firestarters than the Galaxy Note 7"

LOL, That's what I thought at first, but the gloves are actually to protect your skin from getting irritated by the ceramic fiber lining. Some people's skin is sensitive to this material.
Well you could offer them your box - then they could get one of them out of the door

Right around the corner?
Yep.
I didn't say how BIG the corner was

Yes. Right now I'd call it a blind curve. I don't see how they have a leg to stand on with releasing ANY new devices at all, until they publish a compelling explanation for the battery failures, and a compelling resolution. With reports of S7 meltdowns also ominously occasionally appearing, I think Samsung is on very thin ice, and walking on egg shells, concurrently.
