Firm plans to sell fuel converting kit for cars

the straits times may 8
German outfit says that is has made a device that will enable fuel powered cars to use cheaper natural gas (CNG) . This alterntive if used by the people would greately reduce polution caused by cars, as cars using fuel , emit harmful gases which are bad for the environment, natural gas would have no harmful effect on the environment, and ensure that the air will be clean.
i think that if this method is succesful, the world will be in for a greener future, and further more if the natural gas(CNG) really works, many markets would be opened selling new green car products. i see only an upward trend if these devices were to work .
