Pump Up the Bass to Douse a Blaze: Mason Students’ Invention Fights Fires

Pump Up the Bass to Douse a Blaze: Mason Students’ Invention Fights Fires


We’re both graduating
from the Electrical and Computer Engineering Department at
George Mason University, this coming May. We’re here, we’re just gonna test
out our device that we used, that uses sound frequencies
to extinguish flames.>>I see this device being
applied to a lot of things. First off, I think in the kitchen,
it could be on top of a stove top. But eventually, I would like to see
this applied to maybe swarm robotics, where it would be attached to a drone. And that would be applied to forest fires,
or even building fires, where you wouldn’t want to
sacrifice a human life.>>Professor Bryan Mark
really stepped in to help us.>>Just gave us a lot of support.>>I think, as a whole, engineering
is really just finding solutions to, finding some solutions
to complicated problems. Engineering is all about finding a way
to make the impossible possible, so that’s what we do.

  • Eh, I'm not shitting on their creative thinking and hard work but I'll be impressed when they apply it to fires that are actually realistic.

  • Is there something like a 'resonant frequency' for fire? Was there a specific frequency or is it a sweep/range? Plz do tell 🙂

  • But what about the embers? Wouldn't the fire just re-ignite again if the embers causing the initial heat are still there?

  • Way to go.  That's American youth – they are not all dysfunctional as the media portrays – my faith is being restored

  • What category of fires have you guys tested this on and have you considered entire systems for large structures rather than what only looks like a portable model? Would this system be safe around other reactionary chemicals? I can already imagine this as a wider scale fire suppression system. 

  • дорогий старий друг says:

    I can't even fathom how sound can extinguish fire but then again I am not an electrical engineer lol

  • NathanThomas1979 says:

    My question is about how this works in larger scales. Pushing the amount of air/sound around in small forms is fine but to put it into practical use, how safe/dangerous would this be in a larger scale fire? A house? Forest?

    What about grease fires vs. regular fire? Is the application still the same?

  • Stephen J. Mariano says:

    AY I hope you guys make this into commercial product in order to save things such as books and other valuables from water damage!! BIG UPS!!!

  • Meh, not impressed. Let's see you try douse a burning log with that. Blowing out the flame on top of some liquid is not nearly as impressive as putting out something that is actually burning and hot flame energy sick nasty. Looks pretty sick tho. 

  • Lol this is hilarious and stupid. There is no way that sound waves are going to be able to put out fires. Hell, all it's really doing is creating wind to blow it out. This is a stupid invention and academia is even stupider to blow it up. Fuck, one of these days academia might even get me a fucking job for Christ's sake. Oh wait, I forgot, NOBODY TAUGHT ME HOW TO DO THAT with my fucking degree

  • Daniel Wachtel says:

    Wow, the hate escalated rather quickly. Yes, the video was rather uninformative and they should of shown more realistic fires, however, I am sure since this is a small study they used a smaller, more relative sized extinguisher to the size of the fire. As they reach the level of sophistication needed for realistic applications for similar, but albeit larger versions of this product, the tests will become more applicable to real life situations. This was just a small demonstration that was scaled down to show the capabilities of the project. The ethnicity of the students plays no role in what the project can do and it also makes us look bad.  

  • the best thing for your product atm is for you both to become white anglo males….only then you will go somewhere…

  • Kamikaze Gorilla says:

    "Finding solutions to complicated problems…that already have simple answers."

    It's called water and fire-retardants. And they're a hell of a lot cheaper and more practical than a speaker that needs to get within a foot a flame to put it out.

  • Great concept and idea of this! Would just like to know if the energy input in the device increases as the extent of the blaze increase? if that makes sense? also will the temperature of the fire matter in regards to setting of the frequency? Apologies if i sound dumb, my knowledge of physics is very low but really intrigued with your invention. Regardless, keep it up! i can see this changing the world! hope you go far!

  • This is amazing!!! I can only imagine how much water can be saved if we just had a huge one to clear a building. Though you may want to design it so the humming sound breaks cell phones screens that are out in the open so the fire department can clear out crowds of butt heads who get in the way so they can have a 50 pictures to post on their tumbler.

  • The Recombinant says:

    Got a couple questions, if you do not mind me asking. 
    1. How portable is the device? ie. Is it heavy? If so, how much does it weigh?
    2. How much did it cost to make?
    3. Are there any components that degrade quicker than others and need constant replacing?
    4. How much electricity is needed to power the device?
    5. Does this device work on larger fires? Or so far small fires are the most successful in your test?
    6. Does the fuel source matter? ie. does the machine have easier time extinguishing fires gasoline in comparison to wood?
    Sorry, for so many questions. I just find this really interesting to use vibrations to put out fires. This is really cool and this has a mountain of applications. So thank you for your time and hope for a reply.  

  • Lkhagvasuren Davaatseren says:

    how strong it must be to be useful in the forest fire? I am assuming it could help it spread more if not sufficient enough, right?

  • Im not a smart person by any means but isnt this realy good to like stop the fire for a bit so the fire acces the fire more easy and then put it out???

  • Came because of Reddit. I like the video and the idea. And fyi, the etymology of engineering is along the lines of 'a genius design' orginating from Latin 'Ingenious' (or something) and morphed into the word 'engineering'. So yea, this is engineering. Good luck with the project.

  • Laughing Achilles says:

    Applicable to the real world or not, it's a really cool invention. Would it be useful in niche applications, such as lab settings where chemical fire extinguishers can be troublesome? Or where you don't want to blast around whatever it is you are trying to put out? I imagine one of the big problems with larger fires is the remaining heat even when the flames are gone as it can cause things to light back up.

  • I'm skeptic on real world application, thats a lot of air movement needed to douse a fire that would be larger than say a waste paper basket.  You talk about drones and forest fires, I have a hard tiome seeing this being applicable or effective when there are safe chemicals that would doa better job and continue to suffocaste the fire, where as this would need a constant power source.  Perhaps over a stovetop? But what is the human impact?  I've seen vids of books being shredded by isolated sound, so, again, i'm skeptical of this being a viable alternative, Darpa did this years ago, and they too doubt this is going to be an alternative. 

  • The aviation industry uses the same halon (cfc) fire suppression chemicals since 1995 when thier manufacture was banned. All those systems will need to be replaced one of these days. The demo looked like a small version of the engine fires the cfc systems wait for.

  • The fire didn't go out. You make a video about how you built the "fire extinguisher" and don't even show it putting out fires (well it made it die down but not out, when baking soda would do it a lot quicker and safer). Why didn't you set a piece of paper or wood or fire and put it out? Is it because it won't put the fire out? I think you have a great idea, but will not be practical.

  • well done guys, electrical engineers rule! (from a fellow electrical industry student and tradesman). Good luck with your future endeavours.

  • When something is deemed "impossible", that just means someone has yet to figure out an ingenious solution to overcome said obstacle. There are no limits, and no impossibilities; there are only the limits that humanity sets for itself.

  • The applications that this device and technology can offer are amazing. I'm speaking for home owners and people with electronics. Which is pretty much everyone. No one likes sprinkler systems anymore. We all have too many valuables that are damage by water. Imagine only installing basically a sound system around your house to suppress and extinguish a fire. 

    Many data centers don't even have sprinkles and go for fire suppressant systems because water is not an option. But those suppressant systems are insanely expensive. Hopefully this can be the better alternative. 

    Amazing work guys. As a network administrator, I truly do appreciate the work that you have created. I hope this goes big and I can have this system installed in my server rooms. 

  • Anton Savinkov says:

    Это только сковородки так можно, или что-то реальное можно потушить?
    It can snuff out only a fry pan, or something serious?

  • Pretty cool, have you guys tested it on different combinations of fuels and accelerants to see if it's equally effective at things like wood fires, charcoal fires, etc?

  • Полная хрень. Это будет работать только на ьаких маленьких предметах. Он просто сбивает пламя, а доступ воздуха не перекрывает, в связи с чем огонь снова разгорится (что и произошло бы, если проверяли бы не на горящей жидкости, а на дровах, например). Вроде взрослые парни, а такие тупые…
