Re: Diesel - seriously thinking of giving up cycling

There is another important day in court tomorrow in Germany. The German federal courts will have the final say on whether cities (including Stuttgart - home of the mighty Mercedes Benz) are allowed to ban certain types of vehicles as a response to chronically bad air pollution problems. https://www....

Re: Distance on battery

It might seem like a lot of faff but charging everynight after 19 miles will make your battery last a lot longer than if you were wait until the bike had covered 38miles. Known as 'depth of discharge' - this has a big effect on the useful lifespan of lithium batteries. https://energymag.net/dod-dept...

Re: Diesel - seriously thinking of giving up cycling

The UK government has just been defeated in the High Court for the THIRD time over it's inadequate plans to tackle air pollution :D https://twitter.com/ClientEarth Maybe now they will stop pandering to industry lobby groups and squandering public funds trying to defend the indefensible. Perhaps now ...

Re: Diesel - seriously thinking of giving up cycling

The argument is about the malevolent form of nimbyism involved in agitating for a switch from diesel to petrol cars. We can do the switch and improve our local air quality at the expense of dumping the problem of increased carbon emissions on everybody else. Does anyone have a moral justification f...

Re: Diesel - seriously thinking of giving up cycling

The pollution in vehicle exhausts isn't a trivial matter. How they smell is. If anyone argued that we should ban all petrol engines 'cos we don't like the smell of Hydrogen Sulphide we'd all laugh at them. Except it is extremely rare these days to smell H2S from a catalyst. The smell of diesel exha...

Re: Diesel - seriously thinking of giving up cycling

I think we have our wires crossed!

I am criticising MartinC's post because it is apparently trivialising MickF's concerns about not being able to escape diesel exhaust whilst out riding.

Re: Diesel - seriously thinking of giving up cycling

And MickF, although I know you heart's in the right place, if you don't care about air quality in London why do you expect anyone else to care about air quality (or even just how it smells) in Cornwall? Actually, this bit suggests you are also playing down just how harmful diesel pollution is.....

Re: Diesel - seriously thinking of giving up cycling

we decided that most important problem was air quality in London and we needed to undo the work we'd done previously on CO2 emissions to put this right. I agree with everything you've said .................. except LONDON. Are you sure you agree? The OP is arguing that populating the streets with m...

Re: Diesel - seriously thinking of giving up cycling

Yes really: Your example is just arguing over whether moving the deckchairs to the other side might get them out of the ice blown from the 'berg. Vehicle pollution is about far more than local air quality. I'm struggling to understand the point you are making, it seems like more obfuscation in orde...

Re: Diesel - seriously thinking of giving up cycling

Interesting you mention HGVs Much of the current thinking is that the latest emission controls on diesel HGVs are actually quite effective and, unlike diesel cars, HGVs more or less do 'what is says on the tin' WRT emissions. SO much so that NOx emissions from a modern truck COULD actually be lower ...
