Sonic fire extinguisher: new technology allows extinguishing fire without water

In the US, firefighters tested a new sonic fire extinguisher, developed by engineers for situations where the use of water may be undesirable or impossible.

The device uses sound waves that create strong vibrations in the air, preventing the fire from receiving the oxygen it needs to burn. As a result, the flames gradually die down without the use of water or traditional extinguishing agents.

This technology could be particularly useful in areas with limited access to water and where it's important to reduce the risk of property damage.
