Cell Phone Go "Boom".

This is an interesting analysis as to why the Samsung Galaxy Note 7 so spectacularly failed.

Electronics and radio guys, your opinions?

I haven't done any electronic engineering in 15 years or so,so am out of date, but it sounds plausible.

Corporate culture, check.
No room for expansion for a part that will expand, check. This is why pipe bombs with stronger pipe will explode with more force.

The linked article explains the scenario well.

Is that why the Brothers Kablamov used a pressure-cooker for their bomb?

deadstick said...

Yes. The longer you can contain the explosive reaction, the higher the pressure is when the container finally ruptures, and the steeper the pressure rise is when the blast wave reaches the target. The result is higher brisance, which literally means breaking power.

Interesting analysis of the issue, which now makes me understand a little more clearly why we have these fun videos of people running around with their pants on fire from their e-cigs/vaporizers "exploding". It's an actual meltdown, a runaway heat reaction, and it makes me wonder what the next problem area will be as we push battery technology as fast as we can.

Most people have no idea how much energy is contained in those batteries.

Like little bombs should that energy release fast enough.

NiCads could start fires if they shorted, but Nickel Metal Hydride and some of the newer ones can dump that energy even faster. Almost explode

CenterPuke88 said...

Yep, B. That's why the videos of the teens with their baggy pants flaming are so fascinating. The speed with which these exothermic reactions progress "appears" explosive...hence the "My e-cig exploded" stories. But when you look at the video, it's clear that it's just a massive release of heat in a compressed period, nearly an explosion is quite apt, but still very interesting to ponder.

This is why I prefer cell phones with removable batteries. The batteries can self-eject if they expand too much.
