Sensaris's wearable City Senspod makes tracking air pollution as easy as checking the time. The wristwatch-like device uses GPS and Bluetooth technology to display real-time CO2 and ozone levels for your exact location. An "air quality index" is transmitted via Bluetooth to a central database available for public use--so anyone can track air pollution levels around the world.
It might not save you from swine flu, but the Breathing Bud device can at least warn you when air quality is shoddy. The concept device, designed by Xinxin Wang and Zhi Chai, contains a vent at its base that sucks in air for quality analysis. If the air is pure, a beaming blue light shines. If the air is not so great, a pink light pops up. The Breathing Bud derives all its power from your computer's USB port.
When Governor Arnold Schwarzenegger appointed me to serve as the Secretary of the California Environmental Protection Agency in 2003, my first challenge came not from the smoggy skies of Los Angeles or the pesticide-laden drainage from irrigated fields near Fresno, but from a small town in Missouri. Well, actually it came from the tens of thousands of dollars in campaign contributions made to Missouri Senator Christopher “Kit” Bond by Briggs & Stratton in exchange for the lives of about 1200 Americans.
