Seventeen-year-old Ángela Karime Venegas Hernández, a student at CETIS 78 in Altamira, Tamaulipas, Mexico, has invented a unique method to extinguish fires using sound alone. The device, dubbed "Vortex Tech", is a compact system consisting of a 12-volt battery, a frequency generator, and a speaker that emits 30 pulses per second. By creating vibrations, the apparatus displaces oxygen from the flames, causing them to extinguish within five to eight seconds.
To validate her invention, Angela conducted extensive testing, subjecting it to over 100 trials with various materials including wood, flammable liquids, cooking grease, and electronic equipment. The results consistently demonstrated the device's effectiveness in extinguishing these substances without any adverse effects on the environment, residue left behind, or harm to the operator.
Having originated as a classroom experiment, "Vortex Tech" has garnered attention beyond Mexican borders. Angela has been selected to represent her country at an international fair, where she will showcase her innovative approach to tackling one of humanity's most enduring challenges - the battle against fire.
