There will be several changes of government between now and 2040. I rather suspect that future governments might well undergo a dramatic change of views and reverse or indefinitely delay the decision, especially when subjected to voter pressure. At present, one and a half litres of diesel contains more energy than a typical hybrid vehicle battery pack. Certainly a gallon has more potential energy than the best vehicle battery packs currently available.

Then think about how the emergency services are going to respond to calls. An old hydrocarbon fuelled vehicle decides to drive at a hundred miles an hour plus. An electric pursuit vehicle might well catch up with it, but ten minutes into the chase, the batteries will be flat. How about ambulances, fire engines?

Or the scenario where a sudden overnight cold snap causes the power grid to drain all the plugged in electric vehicles as people boil kettles to defrost their windscreens in the morning. Seems like a step back to the 1950s and '60s with the constant struggle to get frozen engines to turn over and start on a winter's morning.

I will be sticking to diesel!

I see a business opportunity for someone to get into Shire horse breeding and cart making.

This is all the result of a political bandwagon that mindless morons in parliament wish to jump on in order get get the 'popular' (ie Unthinking) vote.
So, 40k people a year die of respiratory ailments.. (out of a population of well over 70 Million) are they all non-smokers ?

Many years ago, an Englishman invented the Hovercraft.

In the 1960s, I attended a university lecture by Chris Cockerell. Apart from explaining the technical side of his invention, he related the tale about a visit from the MOD.
They had heard about his machine and wondered what they could use it for. "We want . . . hovercraft . . . "
Cockerell explained that it was excellent cross-country - but the Army had Land Rovers that could do that. Hedges presented a barrier to (even) Land Rovers though could manage narrow gaps. The MOD bods asked if a hovercraft could cross hedges. Cockerell explained that it was all a question of hover height - and that was related to curtain area. The MOD bods asked for a hover height of six feet. Cockerell did a calculation and submitted the dimensions, pointing out that such a size might present problems finding gaps between trees (and, anyway, the Army had trucks that could burst through hedges).
The MOD bods then asked for a machine that could hover high enough to clear any trees that might be around. The resulting calculations produced a machine so large that it could carry - . . . - the entire British Army - which is why the MOD didn't buy them (at least then, though I believe that they did later buy some modest-sized ones that were ideal for sailing up shallow rivers with rapids as 'assault' craft).

Listening to Jeremy Vine today on this subject, lead me to check on charging points in the UK. None beyond a line from Fort William to Montrose. I'm of the opinion that this is an inner city solution, to an inner city problem.
Yet more mis-information! Click link below.

G-CPTN, was at Ballykelly when the Joint Service Hovercraft Trials Unit was visiting in 1965. IIRC it was the size of a Vulcan and very impressive. Hover taxy at low speeds presented problems and they would dump lift and then start up again.

To use a technical term.....utter bollocks.

Charging for people in terraces with on road parking could be solved with trolley bus wiring. Over head cable along the street, charging cables hanging down like petrol pumps. Pays yr money, plug cable in.

It would have to switch off when unplugged to stop people unplugging your cable to charge their car.

MM, did you not read today, police to stop chases in case the Perl has an accident.

If you are a scooter robber, take your helmet off, they won't Pursue!

That would have to be one heavy overhead cable.

A nascent technology that I'm peripherally involved with, the main thrust is to use it for greener fertiliser production than the Haber process which is very carbon dependant. However the technology can also be used either for internal combustion engine or fuel cell powered vehicles. The fuel density is lower than liquids but the ammonia can be handled like LPG so no high pressure or cryogenic storage required and when catalised the resultant exhaust is Nitrogen and Water so no carbon, NO or NO₂ emissions.

Where to start? Ali cables, go to the old USSR and see how they work. Brittle, is the main complaint, they fail regularly where they re attached to plugs. The higher resistance makes the losses in power transmission greater.
The pollution seems to have increased when the amount of traffic has gone down, in London, this seems to have coincided with the anti traffic measures taken. Traffic lights set to slow traffic down, so what transport is there is there longer burning more fuel while idling. Then there's more stop starts, with a lot of drivers 'racing' to the next stop 150 or so meters along the road. The process then repeats. The back roads are no better with speed humps that do the samething.
I would say set the light to increase flow do away the humps and if you really want to slow traffic to 20 mph average speed cams. Then let's see what the pollution figures are.

Of course I could be wrong, maybe the red stuffs at fault.

All those ne'erdowells of an itinerant nature and cannabis growers would think all their Christmas's had come at once.

Or, indeed, Canada. A friend of a friend bought an old house here a few years ago and then had to spend a fair sum of money replacing the aluminium wiring because it was a fire hazard.

Odds are it will be worse, since the cars are using those roads because they're the most efficient way to travel, and will therefore be pushed onto other roads which are less efficient, which will almost certainly result in more pollution.

Just another example of why big government has no place in the modern world.

The vast majority of both transmission and distribution of electricity (at least in the UK) is now by aluminium. Copper can still be found in overhead lines in coastal areas, but most underground cables are now aluminium...generally with mechanical jointed connections...

Piss-poor check.




R means rapid charger
S means standard charger

So I now have to purchase a diesel generator to charge my electric car?
