Mexican student creates an acoustic fire extinguisher to put out fire in seconds

Fire extinguishers that use sound to operate become available for purchase.

Sixteen-year-old Mexican student Ángela Karime Venegas Hernández has developed an acoustic fire extinguisher called "Vortex Tech." This device utilizes sound waves to extinguish fires in seconds. Composed of a 12-volt battery, a frequency generator, and a speaker, it emits 30 pulses per second. These vibrations displace oxygen from the flames, causing them to extinguish within five to eight seconds. Extensive testing confirmed its effectiveness on various materials, including wood, flammable liquids, cooking grease, and electronic equipment. The method is non-polluting, leaves no residue, and is safe for users. Venegas Hernández's innovation, originating from a school project at CETIS 78, will be presented at an international fair to represent Mexico.

The development of an acoustic fire extinguisher by a teenager signals a potential disruption in fire safety technology, moving away from traditional water or chemical-based suppression. This innovation could lead to more accessible and environmentally friendly fire-fighting solutions, particularly for sensitive equipment or areas where water damage is a concern. The simplicity of the components—battery, frequency generator, speaker—suggests a pathway for lower-cost manufacturing and widespread adoption if proven reliable and scalable.

This acoustic approach to fire suppression could significantly impact industries reliant on sensitive electronics or those with strict residue requirements, such as data centers or clean rooms. Its effectiveness across different fuel types also points to broad applicability. The next steps to watch will be independent validation of its efficacy, safety certifications, and whether larger fire safety companies will license or develop this technology further for commercial markets.
