This is stuff you really do not want in your teen’s homeroom: Diesel fumes contain particulate matter and chemicals like benzene and arsenic, which in the long term increase the risk of lung cancer and in the short term cause breathing problems and dull the mind. But luckily for the Sto-Rox students, they had Joe Krajcovic—and a Speck.
AND SO IS YOUR HOME. BUT BREATHE EASY—AN INDOOR POLLUTION REVOLUTION IS IN THE AIR
Krajcovic had installed this new device in his science classroom as a school project. The Speck measures airborne particulate pollution, which increases the risk for and exacerbates symptoms of respiratory problems like asthma. Krajcovic’s class was analyzing the data gathered by the sensor to learn about indoor air quality when they noticed spikes in particle levels every few hours. Those coincided with the generator’s daily schedule: Whenever it kicked on to power the tower’s battery, particulate pollution increased, says Speck developer Illah Nourbakhsh, a robotics researcher at nearby Carnegie Mellon University. After parsing this unnerving data, Krajcovic filed a grievance, and the tower was moved.
