New Fire Extinguisher Uses Sound Waves to Put Out Flames
Apr 01, 2015
(CNN)Boom out da fi-ya! Bass out da flames!
Firefighters may be snuffing blazes with deep-toned sound, if a new device invented by two engineering students in Fairfax, Virginia, catches on.
Viet Tran and Seth Robertson's new fire extinguisher looks a little like a conventional one, but instead of a compressed air tank spewing out chemicals, theirs has a loudspeaker the size of subwoofer drumming out sound waves.
It's not much to listen to, just a low hum, but when pointed at flames, it makes them vanish.
In a way, it's like blowing the fire out, because sound waves are basically multiple, regular blasts of air.

The fire extinguisher uses low-frequency sound waves to douse a blaze. Engineering seniors Viet Tran and Seth Robertson now hold a preliminary patent application for their potentially revolutionizing device. www.gmu.edu
