but kat hawkins has been looking at suntech that might help us to produce less of the killer fumes. —round central london with lincoanopp. but instead of sitting back and enjoying being credible city skylines, i can't quite rest easy because the app we're using for navigation is also telling us how much carbon dioxide and nitrous oxide our car is spitting out in the real—time. it's called air.car and lincoln is part of the team behind it. n0x is a silent killer. it's far worse than c02 and everything we can do in order to reduce the amount of nox people emit into the air is good for the nation's health, good for the environment and we think that we can help people to reduce the amount of nox they produce as they drive. the app works by plugging in a small diagnostics device into the car. this takes data points from the engine and runs algorithms that have been designed by scientists at imperial college london. what we're looking at here is essentially an engine you would find in a car? that's right. it's a relatively old diesel engine by today's standards, but it's been updated with a
