Method for utilizing electric current in place of explosive

In conventional air defense systems, missiles are mainly used, and in rock excavation for tunnel construction, dynamite is mainly used. These methods utilize the explosive force of gunpowder when destroying an object, but it is necessary to use a large amount of gunpowder, and a more efficient method has been required from the viewpoint of reducing the cost burden.SOLUTION: The same work effect as a conventional missile or dynamite can be obtained by a method using the penetration force (shock wave) of a current without using the explosive force of gunpowder which is the energy action of the missile or dynamite. The method of using a current as a substitute for gunpowder is a method of using a physical action of a positive charge and a load of electric energy (electrons) or light energy (light particles). Since the positive charge and the negative charge have the same characteristics as the N pole and the S pole of the magnet, the discharged current is induced using the light energy that is easy to control, so that the current is applied to an object to obtain an effect of replacing gunpowder. The problem is solved by this method.SELECTED DRAWING: None
