Date on the article: 7 March 2024

Also, if you keep reading, it talks about research in 2022.

It's funny to see this on here now, 10 years later. I went to school with both of them. Was and still is a very cool project! GMU produces some pretty good minds out of the ECE Dept.!

Maybe it's the hacker news app but I can't even scroll this article on my phone without clicking on one of the adverts. I once glimpsed the third paragraph but ended up on Amazon 8 times before giving up.

Lately noticed that if I browse the spammiest 10% of the web on Chrome I can't do anything without opening up links I don't want, on Firefox it's a lot better.

So wind blows out fire?

Blowing on fire extinguishes it by removing heat. This device "agitates the air enough to separate oxygen from the fuel, starving the fire."

Reads like an AI written story, maybe with some human editing.

>The prototype already weighed 20 pounds, and in a real firefighting scenario, lugging around a heavy, power-hungry device could be a dealbreaker.

Too heavy? Unlike, I don't know, literally any other fire fighting equipment?

Anyway, it's clearly a silly curiosity and not a serious fire fighting tool. Maybe there is some undiscovered efficient waveguide modified systems that magically puts out forest fires like a wave of a wand but a amplifier and a speaker attached to a tube isn't it.

Not the greatest article, but I love the idea of a fire truck that arrives with fire resistant drones that swarm out, each autonomously extinguishing a small section of fire using sound waves and mist. Definitely still a science-fiction idea, but it’s cool nonetheless. Even if the sound wave idea doesn’t work in practice, they could deliver traditional fire suppression methods at much closer ranges than people can.

I came across these guys working on commercializing it with a bit of a spin on the approach (generating the sound waves a slightly different way): https://www.youtube.com/watch?v=NYUwME-dkC0
