-Pretty sure embedding a fractal pattern on realistic bones would cost more than $1M
-Computers that combust at a critical temperature? Nope. They're made of balsa wood? Plus, a CPU would lock up at a critical temperature.
That said, props for a vivid imagination. I think its a cool concept.


But wouldn't you love to be the guy that just walks up and pulls out the plug, police squad style?

I've burnt up a few computers - releasing the magic smoke, as they say. Computers tend to run quite hot, and even a few minutes with a faulty fan can do it, particularly in essential components with less heat-sink like the southbridge. But, like @swedishfriend said, there's no reason it should light on fire like that.

Interesting. I've heard of batteries combusting, and CPU packaging melting, but never heard of combustion of a CPU or its packaging. How would this happen? What material in the packaging would be susceptible to becoming inflamed?
Also, I know some CPUs have thermal sensors built in to "lock up" at a particular temperature (at least some Intel CPUs). Why wouldn't these kick in? >> ^swedishfriend:
CPUs do combust. It happens all the time. Don't know why there would be more than some smoke though as it wouldn't be surrounded by many materials that would fuel a fire like that. Reading malformed data may cause a system to malfunction which may leave it open for someone to attack it but as stated before there is no reason the data on its own would be executed as a program. Pretty dumb overall. Is this from a spoof type show, I didn't recognize it at all.

Awwww.... how cute


Of course! Thanks, Barseps

WAIT WAIT WAIT WAIT WAIT wait a minute just wait a MINUTE !

How is this being so awesome and not have a combustion engine on it ?!?!?!

I love jets, they are so simple compared to combustion engines

Autoignition temperature
From Wikipedia, the free encyclopedia

The autoignition temperature or kindling point of a substance is the lowest temperature at which it will spontaneously ignite in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion. The temperature at which a chemical will ignite decreases as the pressure increases or oxygen concentration increases. It is usually applied to a combustible fuel mixture.

Autoignition temperatures of liquid chemicals are typically measured using a 500 mL flask placed in a temperature controlled oven in accordance with the procedure described in ASTM E659.[1]

[edit] Autoignition equation

The time t_{ig}\, it takes for a material to reach its autoignition temperature T_{ig}\, when exposed to a heat flux q''\, is given by the following equation

t_{ig} = \left ( \frac{\pi}{4} \right ) \left (k \rho c \right )\left [ \frac{T_{ig}-T_{o}}{q''} \right]^2 [2]

where k = thermal conductivity (W/(m·K)), ρ = density (kg/m³), and c = specific heat capacity (J/(kg·K)) of the material of interest. T_{o}\, is the temperature, in kelvins, the material starts at (or the temperature of the bulk material), and q''\, is the heat flux (W/m²) incident to the material.

To be consistent in units the group \left[ \frac{T_{ig}-T_{o}}{q''} \right] should be squared.

Hate to see the carnage that would cause if it became an external combustion engine.

Exactly how does some office furniture burn for 7 hours, and then raise (fireproofed) steel to over 1000 degrees? What we know from other videos of WT7, is many of the fires extinguished themselves (burned themselves out).

I really doubt that a failure of a steel beam, which supports the floor (and nothing else), could take down an entire building.
Otherwise the facts in this video are generally correct, but misleading. (because office fires don't burn over 1000 degrees)


Actually, cinder blocks will ignite and burn if hot enough and they make up most people's chimneys in their house. Different materials burn at higher and higher temperatures. The heat from the fire pulls in more air, which causes higher temp things to burn, which pulls in more air, etc. etc.

ANY large fire can burn over 1000 degrees. It just needs oxygen in quantity. If some sweaty bastard with a set of bellows can melt iron and steel in a forge, then air sucked in by a huge, uncontrolled fire can do the same. The whole structure doesn't need to bend, just parts of the bottom.

You can't equate a single-room fire test of material combustion with a fully involved structure fire.

...and yes, you are quite right, most fires, if not brought under control, make highrises into death traps.

Fine...let's use Bill Nye's approach...

Follow the logic...

Let's say these puppets on my fingers are humans..."Oooh yay combustion, let's drive cars, build powerplants, make concrete, raise millions of cattle, and pump all these gases into the atmosphere." *Puppets dance*

What happens then? The levels of CO2, CH4, and CO (among other gases) increase. For example, CO2 levels have been increasing AND these activities lead to an increase in CO2 levels. We know this. (http://en.wikipedia.org/wiki/File:Mauna_Loa_Carbon_Dioxide-en.svg)

Let's then say that this orange is the earth -> O (Hello puppet humans!)

The orange is surrounded by something called the ozone layer. Say it with me kids: O-ZONE LAY-ER. Good. Think of it like a sock around the earth (*stuffs the orange in a sock*).

Now, the ozone layer is made up of greenhouse gases - which are usually very good because they trap heat and make it nice and warm for the puppet humans (Yay! *puppets dance*). Greenhouse gases include CO (Carbon monoxide - given off by cars), CO2 (Carbon dioxide - power plants, factories, cars, respiration, etc), CH4 (Methane - cows, pigs, industry, etc), and several others. More pretty pictures --> (http://en.wikipedia.org/wiki/File:Greenhouse_Effect.svg)

So, what happens when the puppet humans increase greenhouse gases? The greenhouse effect gets stronger, and the sock turns into a sweater! *wraps the orange in a sweater* More gases = more trapping = more heat. *puppets melt*

As for global cooling, that dealt with pollution particulates, which have been declining in the atmosphere since government regulations went into effect in the USA (although pollutants from China and other developing countries are causing some slight cooling, which is, ironically, making climate change *less* prominent than it was actually thought to be at this point).

Look at the puppets. Look at them dance *dancing puppets* Okay, now take a nap.
