These 2 Guy’s Invented A Device That Incredibly Uses Sound To Extinguish A Fire

According to National Geographic, uncontrollable blazes fueled by weather, wind, and dry underbrush cause more than 100,000 wildfires every year. These dangerous occurrences destroy 5 million acres of land per year and that includes people’s homes and the wildlife that inhabit these areas.



For those of us living near these sites, here is a glimmer of hope: The invention of two George Mason University students could potentially help in the fight against forest fires. They’ve created a fire extinguisher that uses low-frequency sound waves to douse out a blaze and could potentially prevent the loss of human life. As Seth Robertson and Viet Tran stated in this YouTube video, “engineering is finding solutions to complicated problems.”

How their invention works is by the use of sound waves which are also “pressure waves, and they displace some of the oxygen,” Tran told the Washington Post. When the frequency is right, the sound waves “separate the oxygen [in the fire] from the fuel,” he continues. “The pressure wave is going back and forth, and that agitates where the air is. That specific space is enough to keep the fire from reigniting.”
