Well, a search for "youtube acoustic fire extinguisher" indicates it has already been invented a few times by people all over the world. The most interesting video is https://www.youtube.com/watch?v=ZvnCQg4w4o8

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 channel (The Action Lab) is great, it sets an amazingly high standard for clarity of explanation, and for practical combination of experiments and theory, all while being appealing to a broad audience. Most educators would be extremely proud to produce work that's accurate to the standards of a university professor, while remaining appealing to middle-schoolers. I can't imagine what more you want from the content.

that comparison says more about you than about how high school girls science is

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.

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!

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?

This seems to be a known technology but hasn't made it as a product.[1] 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.

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.

I wonder if she got the idea from https://www.sonicfiretech.com/

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 similar approach. Worked like a charm.

When an oil well goes off, high explosives can be used to extinguish it. Maybe this is the same principle.

This sounds like a cool science fair project being blown out of proportion by the media.

Generally, you get a lot of skepticism when you see an article about high schooler or teenager inventing or discovering something. This is not completely invalid because there have been lots of cases in the past where things like this are just fluff pieces and not actually real breakthroughs, more of a feel good thing. Add onto that that she’s a girl and Mexican and you get even more detractors of the shiftier variety.

I've seen a number of "child invents thing" news stories where the supposed invention was entirely bogus. For example, one widely circulated story in the late 2000s involved a young student in Nepal inventing a solar cell made out of human hair. Their supposed invention made no technical sense, and no one was able to replicate their results.

I sure hope humans are in the loop at those companies, reviewing pics that aren't recognized as faces. If I ever see one of those captchas, they'll get to see some things that no human has ever, or should ever, see.

> Ángela Karime Venegas Hernández is 16 years old and has an idea no one else had.

...meanwhile, some folks at George Mason University were doing this back in 2015[1]:

> The fire extinguisher uses low-frequency sound waves to douse a blaze. Engineering seniors Viet Tran and Seth Robertson now hold a preliminary patent application for their potentially revolutionizing device.

US military showed a version in 2012 [1], and there is a DARPA report[2]

That said, it's a solid student project. I'm sure she'll do well at university.

It’s frustrating that the site wrote that. I’d wager a taco that she never made that claim.
