Why trading in an old diesel car for a new one could be a bad idea

The new hydrogen double-decker will be trialled on London's roads in 2017 and is made by UK bus manufacturer Wrightbus of Co. Antrim in Northern Ireland. London has committed to procuring about 300 zero emission buses by 2020, with 51 battery electric buses recently going into service on the 507/521 route. This took the number of completely electric bus routes to three, with 79 zero emission buses in total in the fleet.

Lynden, the technology to produce hydrogen from water is easy and out there, it is just being suppressed by governments and big businesses who have too much invested in fossil fuels. What is sad is that the only by product of a hydrogen cell vehicle is pure oxygen, what is even sadder is that the most plentiful element in the universe is Hydrogen as well.

I would take that video with a pinch of salt, the guy who is in it, is Bob Lazar who infamously claimed he reverse engineered Alien UFO's for the American government in Area 51!!  :a102:

You might be better to research the Toyota Mirai, which has been on sale in Japan since 2014, at £43,000 it's a little on the pricey side, but you never have to put petrol or diesel in it

A few years back they said diesel was the way to go,now they say diesels are harmful and electric is the way forward, one day they will realise that all the batteries on them will have to be disposed of at the end of their working life and that will be a problem,so what next ?

What we need is a bright spark to find a way of generating fuel cheaply from water. Trouble is if they did we wouldn't be able to afford to drink it. The taxes on it would be too high.
I see the Japanese have gone to Hydrogen on their Tokyo buses.
You are right about batteries. The resources required to make them is ridiculous and after they are done loads more resources to safely dispose of the heavy metals used.

We've all heard about the emissions scandal with VW but it's not as straight forward as it seems. Apparently according to this report some older Euro 4 compliant cars are actually cleaner in the real world than the brand new Euro 6 ones.
Although their official data complies to the standard, they are heavily polluting in the real world. The Nissan Qashqai diesel is one of the worst offenders. Oddly VW and Mercedes seem to be the cleanest and adhere to the standard properly.
