Proposed 60 mph speed limit, Will it REALLY cut pollution? |

My view is that I don't believe it will. Yes, a constant speed is almost always the most efficient way of using fuel, at the right speed that is, but with the high volume of vehicles on the roads, will it actually work?
I suspect all it will do is bring down the average speed of those that usually drive at 80 plus, to a slightly lower level. Does driving faster actually increase the volume of pollutants expelled? After all, the fuel is only being burnt at a faster rate at higher speed, so surely a litre burnt in say, an hour as opposed to thirty minutes will still convert to the same amount output, only over an extended period of time?

QUOTE (motormad @ Jan 8 2014, 05:21 PM) Hydrogen DOES have infrastructure. There are existing petrol filling stations along with LPG stations. We can utilise 90% of the existing infastructure there, would just be pumps etc. Not until they are empty of petrol.

QUOTE (Andy Capp @ Jan 8 2014, 08:20 PM) Big, big farts! The SERIOUS point I was trying to make is that 60mph speed limits, running on electricity, hydrogen etc. is a futile gesture in the big shape of things. Cars & small vans make up a minority part of carbon emission / pollution caused by burning fossil fuels. A 60mph speed limit, buying a Prius, or running your car on hydrogen will not much change the total emissions and their effects.

As I understand it, the proposal was to reduce NO 2 which is a respiratory irritant, and that apparently comes mainly from cars. Diesels specifically. It's not about greenhouse gasses.

Right an injustice - give Simon Kirby his allotment back!
