Commenter suggests niche practical use despite lack of commercialization

A Hacker News user argued the technology, while known, hasn't become a product and might be useful for fixed-distance scenarios like grills or grain silos.
“It might have potential for very specific types of extinguishing, such as grills and grain silos, where the distance from extinguisher to trouble spot is fixed.”

Was looking for a video on this specific work, but only found this [1] where the English translation seems AI-generated. It reminded me of thermoacoustic refrigeration which I found cool (heh) when I had encountered it many years ago - where the compression and rarefaction of sound waves is used to pull out heat. The fire extinguisher seems to…

Infobae has more information (in Spanish) and a video demonstrating the fire extinguisher:

Not exactly acoustic but reminds me of a high school science project we had one year, something along the lines of put out a candle with a contraption. My partner and I rigged up a balloon to be popped by the candle, and the balloon pop blows out the candle. Probably not an original idea, but I don't think any other group in the class tried a…

The article starts with a lie: Ángela Karime Venegas Hernández is 16 years old and has an idea no one else had.As others have mentioned it's not the first time.So, is the reporter willfully lying, or is so incompetent that couldn't even do a simple Google search? I don't know which is worse.

I will not ask if she patented it, or if others had the idea before, or if it is ready to be productized.Just simply: it is great that young people, driven by personal curiosity, go and explore their ideas, find solutions to long-standing challenges.Billiant, keep inventing!

Wow, must be the same school that keeps pumping out students who invent water powered cars and machines that turn plastic into gasoline. HN with another YouTube shorts tier front page submission.

Watching that dude is like watching a child doing science and then using AI to explain the result. If he makes someone curious enough to do experiments on their own it's still a win though.

If she can get it mobile enough , so it can be transported by a drone - it could be forest fire fighting equipment. Bonuspoints if the energy to run it could be derived from the fire itself.

The real advancement, not brute forcing mathematical equations like some company does and claims revolutionary breakthrough. How many ideas like this has come from AI companies' models?

> a speaker that emits 30 pulses per second. That vibration pushes oxygen away from the flamesIs that really what happens? Wouldn't the fire be surrounded by the same air?
-
I remember as a kid somewhat accidentally setting a garbage bin on fire before new year's, and successfully putting it out with one of those big cube firecrackers.
-
It's kinda a throw-away remark in the middle, but I thought it was really cool to realize that speakers produce an on-axis net-blow and an off-axis net-suck.

Prove you are a human to continue.No, I dont think I will. closes websiteCloudflare at the forefront of gatekeeping everything on the website

I'll bet that high school girl's science was better than what's in that youtube (it doesn't set a very high bar)

This is really good. Firefighting foam is a terrible material, when entering groundwater, is a "forever" source of PFAS.
-
Oooh.. from the title I thought this was about an extinguisher for when your guitar catches fire. Makes more sense now
-
When an oil well goes off, high explosives can be used to extinguish it. Maybe this is the same principle.

That's the real test of a song. Electric fire extinguishers are a crutch, really.
