1. A startup called Sonic Fire Tech has developed an acoustic fire suppression system that uses infrasound, which is below the range of human hearing. The system could protect homes and buildings from fires and wildfires.
2. Sonic Fire Tech's technology works by routing infrasound through ducts on a home's roof and walls, activating when sensors detect a flame. The system consumes around 500 watts of electricity and can be powered by lead-acid batteries during power outages.
3. Sonic Fire Tech is currently working with utility companies PG&E and Southern California Edison to demonstrate its technology on homes, aiming to eventually replace traditional sprinkler systems as a more efficient fire protection solution.
