It’s well known that cars create a lot of pollution and that if we can get more people to drive their cars more efficiently (better yet – not at all) drivers would kill the environment a little less. To help drivers figure out how much CO2 they release into the air some enterprising floks created an app called Puff.
Puff is designed to let drivers visualize how much pollution they are emitting on their iPhone as they drive. This way drivers can adapt their driving to minimize their CO2 output.
“Puff is attached to the frame of the car or to the tail pipe. The lamp is light weight and thus well below the 50 pounds you can apparently safely hang from the exhaust pipe. The lamp itself is detachable, so you can take it inside with you whenever you leave your car at the curb. (…) The app also logs the drive data allowing you to keep track of various information such as how much total CO2 you’ve emitted during this trip or during all your trips with Puff, what is the average rate of emission, the total number of miles driven and the average MPG. It also estimates how much NOx, CO and hydrocarbons you’ve released into the environment.”
