The insulator portion is positioned between the floating and ground electrodes to insulate the floating electrode from the ground electrode. The floating electrode induces an electrical charge from the environment surrounding the head member. The floating electrode balances an existing charge on the ground electrode using an electromagnetic induction to collect a plurality of charges in the environment such that the floating and ground electrodes generate a balanced electric field.

Provided is a lightning suppression device for wind turbine blades that is provided at a tip of a wind turbine blade and suppresses lightning struck on the wind turbine blade, the device including: an electrical insulator attached to the tip of the wind turbine blade and formed of a non-conductive material; an internal electrode attached to the electrical insulator on a side opposite to the wind turbine blade; and an external electrode attached to the electrical insulator so as to surround the internal electrode with a predetermined gap therebetween, wherein the electrical insulator is fixed to the tip of the wind turbine blade by a fixing member, and a ground line is connected to the internal electrode.

The present apparatus, system and method solves the problems of the prior art by enabling substantial dissipation of an electrical energy surge coming from communications antenna which has been struck by lightning. The apparatus is for mounting to an exterior of a building at or near communications antenna also located at the exterior of the building. The apparatus is connected with incoming coaxial cables extending from exterior mounted antenna and with outgoing coaxial cables which extend from the apparatus to communications equipment housed within a communications center. The lighting strike surge travels from antenna, along the incoming coaxial cable and is redirected within the apparatus by polyphasers which trip at capacity to redirect the surge to three separate grounding bars and prevent the surge from continuing along outgoing coaxial cables leading to communications equipment thus safely dissipating surge and shielding communications equipment.

An improved concertina wire that is portable and lightweight, easy to handle, and protects against wildfires by absorbing heat and dissipating it through the abundant air gaps in the concertina wire. Made of aluminum, this wire is much lighter and a better heat conductor than previous concertina wire made of steel. Made without razors, this wire can be extruded or stamped into a spiral cylinder using standard tool and die methods. Made with lightweight, non-rusting aluminum, and without razors, this wire can be quickly deployed by most everyone without a machine in front of homes, vehicles, grasslands, forests and such. As coiled concertina wire, a person or animal can crawl into the center of the coils so that wildfires will be harmlessly absorbed by the wire and dissipated into the large air gap between the wires. Formed into a dome around a person, the wire forms a smooth Faraday Gage to dissipate lightning strikes. A smaller embodiment can be wrapped in mesh and permanently installed in a building soffit or frieze board to safely vent an attic and prevent flames and embers from entering.
