Abstract: 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.

Abstract: A shutter for withstanding hurricane wind and pressures has permanent hardware attached to a structure and a temporary shutter that can be stored until needed. Hardware consists of brackets mounted above or below a window and sliding latches at the edges of the window. Sliding latches have a key way for a carriage bolt to enter and attach. Brackets allow a shutter that has attached hinges to latch and pivot around a bridge. The shutter can be made from any material. Hinges are attached to shutter and are able to be latched and pivoted on the brackets mounted on the house. The shutter can also be swung up to protect a high window. The shutter is swung over the window and locked down to sliding latches and carriage bolts with wing nuts through holes in shutter.
