Quote
Two engineering students from George Mason University in Virginia have stunned their professors by inventing a fire extinguisher that uses sound to put out flames.

By blasting a fire with low frequencies between 30 and 60 hertz range, the extinguisher separates oxygen from fuel, explains inventor Viet Tran, who built the device with fellow student Seth Robertson. “The pressure wave is going back and forth, and that agitates where the air is. That specific space is enough to keep the fire from reigniting.”
The pair faced plenty of opposition to their project initially because they’re electrical engineers, not chemical – several faculty members refused to act as advisers on the project. Eventually their professor Brian Mark agreed to oversee their work and not fail them if the whole thing flopped, said Tran.

Although they originally envisioned it as a tool to stop kitchen fires and to eliminate the toxic and messy chemicals used in commercial extinguishers, Tran and Robertson think their invention could be used in wide areas outdoors, such as forest fires, or even in space. A local fire department has also asked them to test their bass waves on a large structure fire.

Read more about the extinguisher in the Washington Post, and check out this project to show what sound waves really look like.

That's imagination at work, thinking like this can change the world, fantastic story, brings sci fi into the real world and . yes. I hope those kids have as much success as Steve Jobs and Bill Gates.

They did this on myth busters a while back, without much success.

Well that means they *didn't* do it on mythbusters.

Probably the difference between two special effects guys VS two PHD students...

C'mon, do it!
