Yes, I kind of discovered that in a dream, in which I extinguished a fire by teleporting away oxygen. It worked, until I stopped teleporting. The oxygen came back and the fire started again. When I eventually woke up I thought about it and I told to myself that I should have chilled the place, not that it matters in real life. I was also proud of my subconscious' understanding of physics.

I wonder if one could use a thermal camera (or some other, high speed sensor) and some kind of feedback loop to squelch it and keep it disrupted until it cools. Or conversely, manipulate the flame for more complete combustion (in industrial processes).

But granted, I have trouble seeing this work on a large scale without much more sophisticated sonic wave tech.

Same application spectrum as CO2 fire extinguishers I'd imagine (which we use for expensive lab hardware that we don't want to get damaged by water, foam, ..., but which are utterly useless for anything more substantial becuase it just reignites).
