Abstract:
A demolishing apparatus using discharge impulse to suddenly melt and vaporize a melting and vaporizing material, said apparatus comprising:a container with an open end;a first electrode or conductive wire with insulating covering with an upper and a lower end portion;a second electrode or conductive wire with insulating covering with an upper and a lower end portion;a cover element containing two openings for receiving said first electrode and said second electrode for attachment to the open end of the container;electrical wiring connected to the upper end portions of said first and second electrodes;a solid and/or semi-solid demolishing material;a granular material selected from the group consisting of metal balls, ceramic balls and pebbles, said granular material being dispersed in said demolishing material; anda melting and vaporizing material connected to the lower end portion of said first electrode and to the lower end portion of said second electrode, said material generating said discharge impulse to supply electrical energy for a short period of time;wherein said container contains the lower end portion of said first and said second electrodes, said melting and vaporizing material, and said granular material dispersed in said demolishing material; andwherein said melting and vaporizing material melts and vaporizes in response to the generation of the discharge impulse;said demolishing material vaporizing and expanding, in response to the melting and vaporizing of said melting and vaporizing material; and,in combination with said discharge impulse of said melting and vaporizing material and the vaporizing and expanding of said demolishing material, said granular material accelerating in response to the discharge impulse and the vaporizing and expanding, said granular material transmitting forces to the surroundings to demolish an object.
