It may seem outlandish, but George Mason University engineering students
Seth Robertson and Viet Tran say they’ve developed a way to extinguish fire
with sound waves.
How can this be?
Low-frequency sound waves in the 30 to 60 hertz range -- can apparently separate oxygen from fuel,” Tran said, in a GMU news release.
“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,” Tran told the Washington Post.
