#CarbonEmissions

This interesting project was made by designer and artist Karolina Sobecka for the World Maker Faire in New York City. Created to raise motorist awareness of their carbon emissions, the Puff comes with two essential components. The first is a cartoon-like cloud that attaches to the vehicle’s exhaust pipe, while the second is an iPhone app that monitors the vehicle’s emissions. When you car produces lots of carbon, the cloud changes color. This alerts both the driver and everyone on the street as to how much pollution is being spewed into the atmosphere.

If you thought the 55mph limit was bad, brace yourself. A study by Dutch consulting firm CE Delft claims that reducing the speed limit to 50mph will cut carbon emissions by as much as 30%.
