But if you don't like catalytic converters, then go out and develop a better emission's control solution that doesn't rob power or efficiency. But I doubt you'll find a better solution that reduces smog emissions without having another adverse effect. |
i believe the figure was ~10% of the ozone related problems are caused by cars. thats a small amount in retrospect. sure the answer to our ozone problems isnt gonna be solved with a emissionless automobile, so why even bother being so strict if the tangible gains are so small? cats are expensive and for all we know we may be wasting more energy on making and enforcing emissions then we are saving
