17-10-2024 (MANILA) A team of ingenious Filipino engineers has captured global attention with their groundbreaking invention: a fire extinguishing device that harnesses the power of sound waves. This novel creation, dubbed the “fire exterminator”, represents a significant leap forward in fire safety technology, particularly for electrical fires where traditional water-based methods pose additional risks.
The brains behind this revolutionary device are University of Mindanao engineering graduates Francis Bagol, Franco Bellera, and Chris John Pogoy, working under the guidance of their adviser, Stephen Paul Alagao. Their invention is specifically designed to combat fires originating from electrical wiring or gadgets, scenarios where conventional water-based extinguishers could exacerbate the danger.
At the heart of the fire exterminator is a sophisticated sensor system capable of detecting fires within a two-metre radius. Upon detection, the device autonomously activates, emitting sound waves that effectively suppress the flames. This automated response mechanism renders the invention particularly suitable for home safety applications, where rapid reaction times are crucial.
One of the most remarkable aspects of this innovation is its chemical-free nature. Unlike traditional fire extinguishers that rely on potentially harmful substances, this device operates solely through the manipulation of sound waves. Furthermore, the inventors have ensured that the device poses no risk to human hearing. The sound output is calibrated to approximately 80 decibels, comparable to the noise level of a standard household vacuum cleaner.
The ingenuity of the fire exterminator has not gone unnoticed in scientific circles. The project clinched second place at the prestigious 2022 National Invention Contest and Exhibit, organised by the Department of Science and Technology. This recognition underscores the potential impact of the invention on future fire safety protocols.
In a move to protect their intellectual property, the team has successfully patented their invention. The official registration of the patent on 13 March 2023 marks a significant milestone in the project’s journey from university concept to potentially marketable product.
