Attorney, Agent or FirmInternational ClassH02H 003/22AbstractA system utilizing ionization produced by beams from laser and laser-like devices to pre-determine the course of stepped leader and lightning channel development, thereby affording protection of life and property. The applications of such a capacity to harmlessly discharge thunderclouds include forest fire prevention, protection of aircraft, protection of missiles and spacecraft (particularly at time of launch), protection of electric power transmission and distribution networks, protection of communication networks, and (to the extent that Vonnegut's electrical theory of tornadoes may be valid) reduction of the destructive force of tornadoes.Field of SearchSeries connected discharge devicesWITH RADIANT ENERGY SENSITIVE CONTROL MEANS Radiant energy responsive load device Load device irradiating the radiant energy responsive device Plural load devices Selective energization of the load devices Selective electric switch controlled by the radiant energy responsive device Plural radiant energy responsive devices Radiant energy control of an electric discharge device in the supply circuit of the load device Discharge control discharge device load controlled by the radiant energy responsive device Radiant energy controlled regulation of the current supply for the load device MISCELLANEOUS SYSTEMS | |
