A group of researchers from Mindanao developed a sound-wave-based "fire exterminator." The project's goal was to put out fires on electrical wires or devices that would be hazardous to do so with water alone.
Francis Bagol, Franco Bellera, and Chris John Pogoy, all engineering graduates from the University of Mindanao, and their advisor Stephen Paul Alagao developed this unique fire exterminator.
How did they do it?
It is said to be the perfect home safety equipment because it has a sensor that can automatically detect and put out fires up to two meters away.
In addition to being chemical-free, the gadget is safe for human hearing since its noise level is only about 80 dB, which is about the same as that of a vacuum cleaner.
However, sound waves cannot eliminate the fuel supply or the oxygen that feeds it; they can only interfere with combustion by lowering heat if they are strong enough.
Patented tech
The team placed second in the Department of Science and Technology's 2022 National Invention Contest and Exhibit.
The project, which was registered on March 13, 2023, has also been patented by the group.
