Depressed people are also likely to self medicate with cigarettes or alcohol. And using cigarettes or alcohol sometimes leads to depression. In some people, it leads to a positive feedback loop.

The very, very small area is probably a few orders of magnitude smaller than your concept of very very small. The ieee article says it will take months to test 1 billion cycles. There are on the order of 10 million seconds in 4 months, which means the researcher thinks he can test at the rate of 100 cycles per second. In other words, the regions are so small, it takes on the order of 10ms to cool enough for the next test cycle.

It wasn't that long ago that we saw that someone had ported Ubuntu to the Nexus 7.

When I worked at a lithium battery factory, we were taught to call it "out-gassing", and never to think of it as "fire". This is because a fire extinguisher would be worthless against an out-gassing battery. Just as rocket engines contain the perfect ratio of fuel to oxidizer for truly spectacular, and dangerous failures, charged batteries contain all they need to ruin your day. Smothering them in water, foam, or CO2 is not going to slow them down.

This is why you don't see many lithium batteries in steel cases anymore. They figured that the pipe bomb configuration was a bad idea.

The linked article shows the capacity as 1mAh per cm of length. A 20cm chunk would have 20mAh. They charge them to 4.2 volts, but I assume the nominal voltage is probably around 3.7volts. So 74milliwatt hours in 20cm.

It is less than half depth. There is a gap for hot air between the front and back units. In the pictures and animation on the Baserock site there are more ventilation slots. It appears that the air enters each through the front and both sides, and exits through the back. This will produce a chimney of heat in the center of each rack.

It varies with local laws. Here is a link from the state of Utah: Girl, 13, charged as sex offender and victim.
