I feel this is a brilliant idea. I'm reminded of the odor I smalled shortly after California's Loma Prieta earthquake in
1989 thinking it was a ruptured natural gas line; PG&E's crew rushed to the area with special sensors and it turned out the odor came from broken glass containers of insecticide in one home's garage, but still ...In today's (12-APR-2010) issue of Science Daily: " " Do you carry a cell phone? Today, chances are it's called " a "smartphone" and it came with a three-to-five megapixel lens " built-in -- not to mention an MP3 player, GPS or even a bar code " scanner. This 'Swiss-Army-knife' trend represents the natural " progression of technology -- as chips become smaller/more " advanced, cell phones absorb new functions. " " What if, in the future, new functions on our cell phones could " also protect us from toxic chemicals? " " Homeland Security's Science and Technology Directorate (S&T)'s " Cell-All is such an initiative. Cell-All aims to equip cell " phones with a sensor capable of detecting deadly chemicals. The " technology is ingenious. A chip costing less than a dollar is " embedded in a cell phone and programmed to either alert the cell " phone carrier to the presence of toxic chemicals in the air, " and/or a central station that can monitor how many alerts in an " area are being received. One might be a false positive. Hundreds " might indicate the need for evacuation. " " "Our goal is to create a lightweight, cost-effective, power- " efficient solution," says Stephen Dennis, Cell-All's program " manager. " " How would this wizardry work? Just as antivirus software bides " its time in the background and springs to life when it spies " suspicious activity, so Cell-All would regularly sniffs the " surrounding air for certain volatile chemical compounds. " " When a threat is sensed, an alert ensues in one of two ways. For " personal safety issues such as a chlorine gas leak, a warning is " sounded. The user can choose a vibration, noise, text message or " phone call. For catastrophes such as a sarin gas attack, details " -- including time, location and the compound -- are phoned home " to an emergency operations center. While the first warning is " beamed to individuals, the second warning works best with " crowds. And that's where the genius of Cell-All lies -- in crowd " sourcing human safety. " " Currently, if a person suspects that something is amiss, he might " dial 9-1-1, though behavioral science tells us that it's easier " to do nothing. And, as is often the case when someone phones in " an emergency, the caller may be difficult to understand, " diminishing the quality of information that's relayed to first " responders. An even worse scenario: the person may not even be " aware of the danger, like the South Carolina woman who last year " drove into a colorless, odorless, and poisonous ammonia cloud.
