| Eco friendly auto-exhaust system
Like a catalytic converter, a chemical solvent or absorbant (of course, capable of absorbing all the bad gases) could be designed and attached to the exhaust system of any automobile. This also can have an air quality meter so that the exhaust's pollution level can be measured and controled. This would make the air we breath cleaner and safer.
