DARPA Creates Machine Which Extinguishes Fires With Sound


"The team arranged two speakers either side of a liquid fuel flame to demonstrate how fire can be controlled by amping up an acoustic field. The sound increases air velocity, which then thins the area of the flame where combustion occurs, known as the flame boundary. Once the boundary area is thinned, the flame is easier to extinguish. "

Pardon my scepticism, but if you can position speakers at the base of a flame, you can also position CO2 nozzles there too.

BUT - this could be significant - a robot carryin
