CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This is a continuation application of Ser. No. 10/437,538, filed May 14, 2003, and entitled "Liquid Nitrogen Enabler." BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to a method of applying liquid nitrogen to a fire and, more particularly, relates to a method of applying liquid nitrogen to a fire so as to maximize the generation of gaseous nitrogen to provide for a greater cooling effect. [0004] 2. Discussion of the Related Art [0005] Conventional means for using liquid nitrogen to extinguish a fire, such as that disclosed in U.S. Pat. No. 6,666,278 to Cicanese (hereinafter "the Cicanese patent" or "Cicanese"), have used the release of liquid nitrogen into a fire column to facilitate the introduction of nitrogen gas into the fire. The mechanism disclosed in Cicanese, however, is limited to the application of oil well fires, and furthermore, the Cicanese patent does not disclose a method to cause mass evaporation of liquid nitrogen in the fire. [0006] Similarly, U.S. Pat. No. 5,327,732 to DeAlmeida (hereinafter "the DeAlmeida patent" or "DeAlmida") discloses an apparatus for extinguishing fires using nitrogen. DeAlmeida, however, relates to a high capacity movable plant that continuously distributes nitrogen in a gaseous or in a mixture of gaseous and liquid phases. However, the DeAlmeida patent does not provide a simple, yet effective means of delivering nitrogen in a timely manner. [0007] U.S. Pat. No. 6,401,830 to Romanoff (hereinafter "the Romanoff patent" or "Romanoff") discloses a process for extinguishing a fire using an inert gas as the fire-extinguishing agent. However, the Romanoff patent fails to disclose an effective means of delivering liquid nitrogen to the fire. [0008] U.S. Pat. No. 5,197,548 to Volker (hereinafter "the Volker patent" or "Volker") discloses a method of controlling a fire through the spraying of liquid nitrogen onto the fire. Delivering liquid nitrogen in the method proposed in Volker, however, may leave glowing embers capable of re-igniting the fire. [0009] The need therefore has arisen to provide a simple, effective, method of separating liquid nitrogen into small droplets so as to cause mass evaporation in a fire draft such that extraneous gases, other than the evaporant, are prevented from entering the fire. [0010] The need has additionally arisen to provide a method of applying liquid nitrogen to a fire such that the fire is not susceptible to re-ignition. Furthermore, a need has arisen to provide a method with a simple, yet effective delivery means such that the method may be employed quickly in the area of a fire. [0011] Additionally, the need has arisen to provide a safe and effective method of rendering land mines inert so that they may be safely transported to a detonation chamber. SUMMARY OF THE INVENTION [0012] In accordance with one aspect of the invention, a method of using liquid nitrogen to control and extinguish a fire by dispensing liquid nitrogen as substantially small droplets and applying it to a fire so that the fire is substantially consumed by the liquid nitrogen so as to rob the fire of oxygen. [0013] In another aspect of the present invention, a method of extinguishing and stopping the travel of a wild fire with a directional travel is disclosed through the assembling of a trough or pipe at a direction ahead of the travel of the fire, wherein liquid nitrogen is supplied in the trough or pipe so as to extinguish and stop the travel of the fire. [0014] In another aspect of the present invention, a method of extinguishing and controlling a fire contained in a tall structure such as a skyscraper and the like is provided wherein a trough carrying liquid nitrogen is employed through an opening in the structure so as to apply the liquid nitrogen directly to the fire. [0015] In accordance with another aspect of the present invention, a method of freezing a land mine using liquid nitrogen such that the mine is rendered inert and may be safely transported to a detonation chamber nearby. [0016] In yet another aspect of the present invention, a method of using liquid nitrogen to freeze and safely remove explosives, in particular, buried explosives is disclosed. [0017] These and other advantages and features of the invention will become apparent to those skilled in the art from the detailed description and the accompanying drawings. It should be understood, however, that the detailed description and accompanying drawings, while indicating preferred embodiments of the present invention, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof, and the invention includes all such modifications. BRIEF DESCRIPTION OF THE DRAWINGS [0018] Preferred exemplary embodiments of the invention are illustrated in the accompanying drawings in which like reference numerals represent like parts throughout, and in which: [0019] FIG. 1a is a side cross-sectional view of the trough of one embodiment of the present invention; [0020] FIG. 1b is a top plan view of the trough illustrated in FIG. 1a; Continue reading about Liquid nitrogen enabler...
