Seems to be a decade old technology, but I just discovered it this morning and thought it was pretty cool:

Sound Waves to Fight Wildfires: How Does it Work? | Dell

Amid deadly wildfires across the globe, technology offers a promising solution once deemed impossible: Extinguishing wildfires with sound waves.

Acoustic technologies were unsuccessfully tested as a firefighting tool by the United States Defense Advanced Research Projects Agency back in 2008. Undaunted by past failures, as well as skepticism from classmates and faculty, Robertson and Tran solved the problem by adding vortex rings, which move particles in circles around a center core, to carry sound waves over longer distances without losing mass or kinetic energy.
