Firefighters show off amazing new way to extinguish flames — by blasting them with sound, not waterBy Jeanne Erickson. Published April 18, 2026, 12:14 p.m. ET
The sound you can’t hear might just save your house.
It sounds like something out of a sci-fi blockbuster, but firefighters in California are firing up a fascinating new way to fight flames — with sound waves.
The San Bernardino County Fire Department recently showed off a futuristic system that detects and extinguishes flames without water or chemicals.
Instead, it uses powerful — but completely silent — sound vibrations to snuff out the fire itself.
Way cool tech. Hopefully coming soon to buildings everywhere.
