Acoustic fire suppression goes commercial.

“Infrasound stops kitchen fires” reads like “we found a way to bully the flame until it lets go, ” which is basically the fancy version of blowing out a candle. I’m curious how it behaves once there’s real fuel involved (grease, cabinets, plastics) because knocking down an open flame is one thing, but stopping re-ignition feels like the part sprinklers are still annoyingly good at.

Okay so yeah, the “bully the flame” part tracks, but it feels like it’s only interrupting the reaction for as long as the sound is on — the second you stop, you’re back in the same heat/grease-vapor situation and it can just light again. sprinklers (or even a messy powder extinguisher) win because they change the environment after the flame’s gone, not just the flame itself.
