A method of suppressing a wild fire raging towards a target region of land in a direction determined by prevailing winds and other environmental and weather factors. Prior to a wild fire reaching a target region of land, a GPS-guided system is used to apply an anti-fire (AF) chemical liquid mist over a GPS-specified fire break region, in advance of the wild fire and containing molecules that cling onto vegetation and form a fire break region, while providing a non-treated region of sufficient size between the front of the wild fire approaching the target region of land and the fire break region. When the wild fire reaches and moves through the GPS-specified fire break region, the molecules clinging onto the vegetation reduce the free-radical chemical reactions raging in the combustion phase of the wild fire. This reduces the destructive energy of the wild fire, thereby suppressing the wild fire and protecting the GPS-specified target region of land.

A full jet nozzle for use with a water cannon, the nozzle having a body that encloses a flow channel running along an axial direction, having an outlet opening provided at an axial end of the flow channel, which has an external circumference which encloses an outlet surface to form a flow cross-section. The flow cross-section has a substantially circular or annular base area. There is at least one radial cross-sectional extension of the outlet area is provided exclusively in an angular range of the outer circumference of a maximum of 180. The full jet nozzle also has at least one radial cross-sectional extension formed by a slot running with its longitudinal axis parallel to the axial direction, which opens perpendicular to the base area or has a recess running with its longitudinal axis parallel to the axial direction, which opens perpendicular to the base area.

A dual air vent assembly for wet pipe fire protection sprinkler systems allows air or gas to vent from system pipes as they fill, without spilling any water into the fire-protected environment, even if an air vent valve, operative to discharge air or gas but not fluid, fails. A shut-off valve is upstream of the first air vent valve, and a reservoir is downstream of it. Small amounts of water that escape the first air vent valve are collected in the downstream reservoir, and evaporate. The reservoir also collects fluid if the first air vent valve fails. In response to fluid in the reservoir at or above a predetermined level, the shut-off valve is actuated to arrest the flow of fluid into the first air vent valve. No water escapes the assembly, even if the first air vent valve fails. The shut-off valve may be electronically or mechanically actuated.

Fire spikes and fire spike tips adapted to penetrate a surface and distribute a fire suppressant, such as, water, on the opposite side of the surface are provided. The fire spike tips include a cylindrical body having a first end adapted to be received by a conduit and a second end having a pointed projection adapted to penetrate the surface; an internal cavity in the cylindrical body having an open first end and a closed second end; a plurality of first orifices in the body, each of the plurality of first orifices directed in a first substantially radial direction; and a plurality of second orifices in the body, each of the plurality of second orifices directed in a second direction which at least partially intersects with the first direction of the plurality of first orifices. Kits for the fire spikes and methods of suppressing fire are also provided.

A fire suppression drone comprises a main body, a plurality of propellers provided on an outer circumference of the main body and driven by a driving motor, a pump provided in the main body and connected to a water feeding vehicle through a water feeding hose, at least one water jet nozzle provided on the outer circumference of the main body to jet water supplied by the pump, a camera provided on the outer circumference of the main body, and a controller connected with the driving motor, the pump, and the camera and connected with a remote controller to be wirelessly communicable with the remote controller, wherein the remote controller includes a monitor, the monitor capable of display, in real-time, an image captured by the camera.

A nuclear reactor chamber comprises an inlet portion. The chamber is a part of a nuclear power plant. At least one container contains liquid nitrogen and cold nitrogen vapor and includes an outlet portion. At least one thermally activated release mechanism is respectively connected between one of the at least one container and the inlet portion. Each thermally activated release mechanism is configured to release the liquid nitrogen from a connected container into the inlet portion when a predetermined safety threshold temperature is reached, so that the released liquid nitrogen produces an expanding volume of cold nitrogen vapor within the nuclear reactor chamber.

A modular energy storage system includes a housing, a plurality of energy storage devices, a first door assembly and a second door assembly. The housing includes a first end and a second end. The plurality of energy storage devices are coupled within the housing. The first door assembly is pivotally coupled to the first end of the housing. The second door assembly is pivotally coupled to the first end of the housing adjacent the first door assembly. The first and second door assemblies each comprise an air distribution member configured to distribute and direct a cooling air flow toward the plurality of energy storage devices to absorb heat energy from the plurality of energy storage devices.
