The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An electrostatic charge deionizing lightning conductor, comprising two frameworks having different geometries and being electrically separated from one another; insulators which electrically separate said frameworks from one another and a must supporting said frameworks and said insulators and being electrically insulated; each of said insulators being provided with a variable dielectric according to an atmospheric electrostatic field, so that each of said insulators, when each of said insulators balances an energy within it, annuls a saturation of electrical charges in an atmosphere for a protected area which are responsible of thunderbolt formation with a scope being variable according to a geographic area to be protected and said values being of about a 650 meter radius.
2. An electrostatic charge deionizing lightning conductor as defined in claim 1, wherein said frameworks are composed of aluminum.
3. An electrostatic charge deionizing lightning conductor as defined in claim 1, wherein said insulators include three said insulators.
4. An electrostatic charge deionizing lightning conductor as defined in claim 1, wherein said variable dielectric is an inert gas.
5. An electrostatic charge deionizing lightning conductor as defined in claim 1, wherein one of said frameworks is ring-shaped, while another of said frameworks is inverted pear-shaped.
