Jacek Wilk-Jakubowski BEng MSc PhD who is the Erasmus+ and CEEPUS Scholarship holder, is the author of an interesting project: an acoustic extinguisher 🧯🔊.
The innovative fire extinguisher suppresses the fire with sound waves. What may have looked like fantasy a few years ago today is confirmed by facts. An acoustic fire extinguisher was created at the Kielce University of Technology.
Inspired by trials conducted all over the world, the scientist decided to develop a device which, among many advantages, also has the most important one: it is not as destructive as in the case of traditionally used water or extinguishing foams.
The advantages of this technology include lower costs of operation and firefighting. The device extinguishes the flame from a distance of nearly two meters. It can be operated remotely, which means that a person does not have to be close to the fire source. Interestingly enough, not every type of sound is suitable for extinguishing. Jacek Wilk-Jakubowski BEng MSc PhD experiments show that bass is best for this – waves with a frequency close to the lower limit of what a human being is able to hear.
The inventor is working together with Paweł Stawczyk and scientists from the Technical University of Bulgaria. The prototypes have already been tested in the open air for liquid and gas extinguishing, and the tests were successful. We are very proud! Congrats and good luck in testing this innovative extinguisher
