Using foam to put out fires is so yesterday. Undergraduates at George Mason University have demonstrated that it’s possible with a portable device that uses soundwaves instead. The device is unimaginatively named the ‘Sound-Blasting Fire Extinguisher’ and weighs around 20 pounds.
Currently it can only put out small fires but the potential is there and in the future this will provide a way to fight fires that doesn’t ‘run out’, that will be fine to use on fat fires and that will just be an awful lot cooler.
Also provides handy defense against Venom and Carnage (that one is for the comic book nerds).
