Idea for Hyundai: I have had likes from various car sites regarding this idea which I am giving to various car manufacturers: For polluted cities: Put electrostatic precipitators on car roofs and drive through the dirty air. An electrostatic precipitator works as follows: Gas (eg air) is ionized by passing it between two highly charged electrodes. The ions then attach themselves to dispersed particles (dust and so on) in the gas. These particles then migrate towards oppositely charged electrodes and are so collected, cleaning the gas. Hyundai could drive such cars through polluted city streets. The electrostatic precipitator could clean outside air and also pump clean air into the interior of the car. Another idea is to put a catalyst on the roof or in the paint that would clean the air (platinum, rhodium, etc). If the roof got hot enough to significantly speed up the chemical reactions to reduce pollution it could clean up the atmosphere a lot. Also see below: In Chemistry by Raymond Chang we read that, A recent technological innovation to combat photochemical smog is to coat automobile radiators and air conditioner compressors with a platinum catalyst. So equipped a running car can purify the air that flows under the hood by converting ozone and carbon monoxide to oxygen and carbon dioxide... A drive on the freeway would help clean up the air!
