The Puff, a cloud of plastic that tells you just how much your car’s been polluting

So, you drive a Hummer, all that power and muscle showing, making heads spin around as you drive by. You probably don’t care too much about just how much gasoline you’ve been burning, cruising around. We seriously doubt you’d want one of these too! Well, this sure is for the environment-conscious folk out there, who like giving their gas-guzzling cars a twist. Behold the Puff! Basically a cloud-shaped car accessory that fits on to a car’s exhaust pipe, this one tells you just how polluting your car is using a series of different color lights. Now, a simpler and smaller device would have sufficed. The designers decided to make this one turn your car into a bad animation though. With green lights for less emissions and a flaming red for exhaust puffers, the Puff keeps users informed about their car’s emissions using an iPhone application.

We’d rather prefer having our car’s emissions checked by professionals, instead of using a plastic cut out stuck on to its exhaust pipe though.
