A PAIR OF UNIVERSITY STUDENTS IN ENGLAND have just won an international design competition award for their innovative kitchen faucet. Dubbed the Automist Faucet, it is a sprinkler-type device that ejects water under enough pressure to mist it and supposedly extinguish kitchen fires. According to The Guardian:
The creation can be fitted to any standard kitchen tap. If a fire breaks out, a built-in heat detector triggers a pump installed under the sink which sends out a high pressure mist of water droplets through nozzles at the base of the tap unit, suppressing the blaze.
“We learned that fire extinguishers can sometimes actually be a hazard, because people stay and try to fight the fire rather than just getting out. We wanted to design something that would use a completely different approach,” one of the inventors said.
Not only does the misting displace the oxygen, but it has a cooling effect, too. The two designers, Yusuf Muhammed and Paul Thomas have teamed up with a pair of design engineers to form a company to further test the device and then market it.
When asked about the dangers of applying water to a grease of cooking oil fire, they tell Business Week: “It’s an issue we’ll have to overcome as we move to commercialize our idea. But mist is different: the water particles are really small. You’re not throwing water on oil. Instead, water turns to steam which gets rid of the heat, it displaces the oxygen around the fire, and that stops the combustion process of the fire itself. These days they even use water mist sprinklers to protect industrial deep fat fryers.”
This promotional video illustrates the operational theory of the Automist:
Folks in the Firegeezer generation will no doubt recall the John Bean high-pressure pumpers that utilized the same principle back in the 1960′s. Ideally, it allowed you to extinguish an interior room-and-contents fire with less than 50 gals. of water. Using a 4-stage centrifugal pump, it generated fire flows at up to 500 psi through a booster line, creating a high-pressure mist similar to the concept used in this new faucet.
