Wildfires release enormous quantities of carbon dioxide and other greenhouse gases in addition to devastating animal habitats, destroying homes, and causing fatalities. Drones equipped with artificial intelligence to navigate through wooded locations, fire-detection hardware, and firefighting hardware can protect the environment by preventing wildfires. Methods can use a drone system that includes one or more drones to prevent wildfires. Each drone can include an infrared camera configured to detect fires. Each drone can fly in view of areas that might have a fire. After detecting a fire, the drone system can put out the fire if the fire is small. The drone system can also notify systems and people who can put out the fire.

Wildfires can quickly grow to enormous scales with devastating environmental impacts. Drone systems that provide early detection of wildfire risks can prevent wildfires before they grow out of control. Methods can use drones equipped with artificial intelligence to navigate through wooded locations and detect fire risks. Drones can include fire-detection hardware and fire-fighting hardware.

The present disclosure discloses a device for detecting and alerting of a fire at the vicinity thereof. The device is deployed in an area at the outdoors, e.g. a forest, that is desired to be monitored. The device has two main parts, a first part that is intended to remain relatively cold and therefore is thermally isolated from the environment. The first part can be isolated by being inserted into a static object in the desired area, e.g. a trunk of a tree, or a rock, or, in some embodiments, can be surrounded by a thermal-isolating material. The first part is thermally connected to a first end of a thermoelectric generator (TEG) unit and a second part of the device, a hot part, is thermally connected to a second end of the TEG unit. The second part is intended to be thermally exposed to the ambient environment such that in case of a fire in the vicinity of the device, the second part is heated to high temperatures while the first part remains relatively cold since it is thermally isolated. Therefore, the second part causes the second end of the TEG unit to heat to high temperatures while the first end of the TEG unit remains relatively cold since it is thermally connected to the thermally-isolated first part that may be considered to function as a heat sink. The temperature difference between the two ends of the TEG unit generates an electrical energy, e.g. a voltage difference that is supplied to an alerting unit in the device. The alerting unit is inactive as long as there is no generated electrical energy by the TEG unit and become active only when the temperature difference reaches a certain value. Upon being activated by the electrical energy of the TEG unit, the alerting unit is configured to transmit an alerting signal indicative of the location of the fire. The alerting signal is received by a receiving station and triggers operation of fire fighters for extinguishing the fire quickly.

A system and method that is both effective and accessible. The system is machine-learning enabled, reliable, scalable, versatile, and may be efficiently installed. The system will improve US, state, and local fire suppression efforts because more homeowners will successfully evacuate if they have access to protection. Also, it may allow more fire crews to focus their efforts on the flame front, rather than suppressing structural spot fires in areas where the systems are installed. The system significantly reduces insurance and governmental suppression costs which would provide significant incentives to homeowners. The system minimizes fire related damage to the home, may operate independently from local utilities, may remain in service with minimal attention from the homeowner, and minimize the impact of system discharge on the environment. The system does this by precisely targeting firebrands and discharging only the amount of aqueous solution needed to extinguish the firebrand.

A fire protection system for retarding the spread of wildfire toward a structure includes a structure positioned on a ground surface. A tank contains a fire retardant fluid. Each of a plurality of sprinklers has a base coupled to the ground surface with a line extending outwardly away from ground surface. Each sprinkler has a nozzle coupled to a distal end of the line relative to the ground surface. The line of each sprinkler is fluidically coupled to the nozzle and the base. Each of a plurality of heat sensors is positioned proximate a respective sprinkler of the plurality of sprinklers. When one of the plurality of heat sensors detects a predetermined rate of heat, a CPU activates a pump to pump the fire retardant fluid from the tank to the base of each sprinkler.

A system and method for extinguishing wildfires with the assistance of soundwaves at a distance is provided. The system generally comprises a camera, output device, waveguide, processor, power supply, and a non-transitory computer-readable medium having instructions stored thereon that instruct the processor to perform operations of the system. In one preferred embodiment, a database may be operably connected to the processor and store any data associated with a combustion reaction therein. In some preferred embodiments, the system may comprise a computing device having a user interface, which may present, to a user, data that may inform the user about a particular combustion reaction and/or allow the user to control the system remotely. The system and method are designed to safely stop wildfires without a resource that must be spent and subsequently replenished.

A fire retardant delivery system for use with a source of carrier for protection from wildfire is provided. The system includes a retardant tank for storing a fire retardant. The retardant tank is in fluid communication with the source of carrier. A metering valve is constructed and arranged to meter a flow of fire retardant injected into the carrier discharged from the source of carrier to maintain a predetermined proportion of fire retardant to carrier, thereby creating a fire retardant and carrier mixture. At least one distribution nozzle is configured to deliver the fire retardant and carrier mixture to a desired area.

An outdoors fire alerting device, including a first part and a second part spaced apart from one another by a thermoelectric generator unit, the first part being shaped for insertion into a static object and the second, exposed part intended for being exposed to the ambient environment while the first part is retained within the static object; the first part, the second part and the thermoelectric generator unit being integrally coupled to one another, the thermoelectric generator unit being configured to generate electrical energy in response to a temperature difference between the first part and the second part, an alerting unit electrically coupled to the thermoelectric generator unit and configured to transmit a signal indicative of fire alert when the temperature difference between the first and the second part reaches a predefined value, where the first part has a generally cylindrical shape and is elongated along a first axis, where the first part is axial symmetric about the first axis.

A device for characterizing a fire comprises at least one stereovision system and at least one processing unit. The at least one stereovision system comprises a first and a second image capture unit. The at least one processing unit is configured to determine at least one geometric characteristic of the fire. The processing unit is also configured to determine a radiative flux of this fire on the basis of a calibrated linear relationship established between a radiative flux of a reference fire as a function of at least one of the geometric characteristics of the fire and of at least one fire category in order to be able to determine zones exposed to a radiative flux that exceeds a reference threshold. The present disclosure also relates to a method for determining radiative fluxes that implements such a fire characterizing device.

A system and method for protecting an area from fire having one or more area fire prevention units capable of discharging fire suppressant via a directable nozzle, each fire prevention unit being communicatively coupled to a computing device which detects airborne firebrands, predicts their trajectories and final landing positions, and directs one or of the fire prevention units to discharge fire suppressant toward the firebrand at its final landing position. Depending on configuration, the system may further use wind data, GPS, and terrain models to calculate the trajectory and final position of the firebrand. Also depending on configuration, the system may calculate a spread and distance of suppressant discharge, a nozzle aperture, and an amount of suppressant to discharge. Some embodiments may use trained machine learning algorithms to make one or more of the system's calculations.
