Good Description of Nukes and the China Syndrome
Too bad the author is a thermite-sniffer-- nonetheless:
The presence of spherules of iron in multiple dust samples is indicative of molten iron widely dispersed. This is important because the official NIST investigators acknowledged there is no evidence to support that the steel columns in any way melted. They said in a 2006 Factsheet: “In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36).”See http://wtcdemolition.blogspot.com/ and http://wtc-chinasyndrome.blogspot.com/ for more on nukes and the China syndrome.
But why are “microspheres” of iron significant? Surface tension naturally determines the spherical shape of a liquid suspended in air. Given that spherical-shaped iron particles are found in the dust, and molten iron is subject to surface tension, it is easy to suggest that the spheres were once in a molten form suspended in air. No other phenomenon can plausibly explain that particular shape in this circumstance. An analysis by the United States Geological Service (USGS) found iron-rich spheres in dust produced during the destruction of the towers.
Another supportive finding for the truth movement’s suggestion explosives were used in the destruction of the buildings is the observation of flowing molten steel in the basements of WTC 1, 2, and 7. (WTC 7 is a special case, having dropped straight down into its own footprint at near free fall speed, as did the others, after not being hit by a plane, and suffering considerably less damage to its structure than its neighbors WTC 4 and 5. The hulking steel frames of these buildings survived without collapse, and required demolition even after sustaining heavy damage and intense, engulfing fires.) Many people involved saw the flowing steel in the basements while in the recovery effort and the clean up. It persisted for at least 100 days. The heat signature was recorded by satellite-based thermography, (and here). What sort of temperatures are needed to create molten steel, and how would such a thing happen in not one, but three, generalized locations?
As mentioned above, iron melts at about 1500C. Not only does iron require a large heat source to become molten, the source must be sufficiently hot, for a long enough period, to overcome the thermal conductive properties of iron. Iron conducts heat energy quite well, efficiently drawing heat away from the area being heated to cooler parts. An energy source must continue to add energy to the metal as the heat is conducted away from the concentration of heat for the iron to melt. The amount of heat necessary to melt a quantity of iron to a molten flow must either be hot enough for a protracted and steady heating, or the heat source must be very intense, with excess heat sufficient to easily overcome the iron’s conductive properties and melt the iron.
This type of energy is neither explained by any of the official investigations, nor supported by the observed event of destruction under the assumption the official explanation is correct. In this line of reasoning, gravity caused the disintegration of the buildings, after fire damaged the supports. It would have to follow that gravity somehow contained the energy to spontaneously generate enough heat to melt iron in three separate collapse events, and under different circumstances in one of those three collapses. Or, if the molten iron is to be explained by residual fires that persisted after the collapses, what would the thermodynamic properties be of the fuel burned in those fires to generate temperatures hot enough to create Dante-esque scenes of flowing, molten metal? Hydrocarbon fires: jet fuel, office materials, carpets, plastics, nylon burn under the most ideal, highly ventilated conditions at about 650C. Air temperatures under blast-ventilation conditions can attain 1100C, but this is difficult to sustain, especially under a smoldering pile of rubble, or in the extremely smoky, sooty, dispersed fires seen before the complete destruction.
The intensity of the molten pools were such that according to the US Department of Energy’s Lawrence Berkeley National Laboratories, “Approximately three million gallons of water were hosed on site in the fire-fighting efforts, and 1 million gallons fell as rainwater, between 9/11 and 9/21…” and all this water still failed to extinguish the basement fires. This was simply the ten-day window in which they looked. The spraying down of the pile persisted for months.
This type of energy is not explained by gravity, or by residual hydrocarbon fires, and is unusual in light of the amount of water dumped on the fires.
