"Sound Waves: The Future of Fire Extinguishing"
Originally Published 2 years ago — by Hackaday
A recent video by The Action Lab explores the use of sound waves as a fire extinguisher, demonstrating how a combination of a bass reflex port and an air vortex cannon can effectively extinguish flames by oscillating and diffusing the air, cooling it, and alternatingly pushing oxygenated air and carbon dioxide-heavy combustion fumes into the flame. This approach could be practical in low- and zero-gravity situations, such as space stations, where traditional fire extinguishers are less effective.
