It seems that NIST did not follow due diligence in following up on these reports, statements from witnesses, Tulley was hired to do the cleanup, are we to suppose his people would not know molten metal/steel with their own eyes?
Again. You cannot tell a molten substance by sight alone. Especially when there are other materials that could have mixed with it.
That is a fact.
How were the temperatures maintained? It couldn't have been thermite as that burns very rapidly.It is reasonable for people to come to the conclusion at the time, that the molten material under the piles of wreckage were a residual effect of whatever caused the towers to fall.
Something burned hot enough and long enough for witnesses to make these kinds of statements.
So what do you suggest?
The thing with aluminum is that it cools more rapidly then steel, this is why it is used as heat sinks in many electronics. It has a higher heat transfer rate then steel. This is why aluminum engine heads are used. It radiates/conducts away all of its heat so rapidly that it cools off much faster than anything else. So if a piece of aluminum were to be in contact with a piece of steel, at melting temps, the aluminum would transfer its heat to the steel.
Aluminum will not stay hot longer then steel. Certainly not for the length of time the piles
remained at the reported temps. Please correct 5this if I am wrong...
Which will cool faster? Archive - Physics Forums Archive
Hot objects transfer heat to their surroundings by radiation. If you put a pot on top of the red hot coils, the coils often cool down enough to see the decrease in the brightness of the coils; this is because conductive heat transfer away from the coils decreases the amount of power that must be removed by radiation and convection to the air.
When you start stacking metal layers on top of each other, like a sheet of
steel and a sheet of aluminum, you are adding interfaces. And the heat
plate is going to have to get hotter to transfer the same amount of heat
through these interfaces.
Question: I am in search of a metal that when heated, rapidly dissipates the heat, and cools quickly.
Replies: In terms of cooling quickly, what you want is a material with low heat capacity and high thermal conductivity, and you want to have as little of it as possible (low mass). There are lots of metals that fit that bill, but in terms of overall usefulness and cost, aluminum comes to mind.
Metals for Soldering Irons, Cool Quickly
IOW's, if it was aluminum melting in the rubble piles, the fuel source would have to remain high and constant, as aluminum rids itself of the heat much faster then say steel...Regardless NIST ignored the reports of the molten steel/metal altogether, and this is one strike against them IMO.
We have to dig into their reports to find evidence of any extreme temps and times that suggest any steel was melted or weakened
I would like to discuss this next, after any opposing comments..
Mr. Jones.
The point I am trying to make is this.
There is no proof that the molten metal seen was molten steel. That is a fact. You could not have visually determined what the molten substance was by sight alone.
