Abstract: A method and apparatus for weakening a storm uses liquid or solid nitrogen. In one embodiment, the method includes the steps of providing liquid nitrogen enclosed within at least one container, dropping the container into a storm, and dispersing the liquid nitrogen from the container starting at the top of the storm, whereby the nitrogen cools and therefore weakens the storm. In another embodiment, the method includes the steps of providing solid nitrogen pieces each sized to melt and evaporate in the time it takes to fall from the top of a storm along a major portion of the height of the storm and dropping the solid nitrogen pieces into a storm, whereby the melting and evaporating nitrogen cools and therefore weakens the storm.

Abstract: A process for extinguishing a fire, using an inert gas in its liquid phase as the fire extinguishing agent. The extinguishing agent must be a clean agent so it must not be electrically conductive and it must not leave any post evaporation residue. The extinguishing agent possesses properties that make the agent the capable of extinguishing fires. Also, the process does not have any effects that are harmful to the environment.
