Is any manufacturer willing to say that it wants to hide the emissions of its cars? Or to say that emissions are a good thing?
This should be a no brainer. In the long run, we're all dead. John Maynard Keynes
What they never mentioned was that it became CO2 in next to no time and had little effect on the streetside atmosphere.
But it was cheaper to install catalytic converters than to seriously change the way petrol is burnt in cars to remove NO, NO2, SO, SO2, which are pretty noxious at all times. Nobody mentioned that.
Score for the industry. keep to the Fen Causeway
Or to say that emissions are a good thing?
Well, they don't need to be. In a hydrogen based transportation economy the emissions, water, could easily be collected during transport and then released where it is most valuable. It may not be worth doing in most climates but remains a possibility. As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
