8 hundred and 92 knobheads

exemption from the London Congestion Charge for wholly electric vehicles, together with free parking in Westminster, the City and Camden. I suspect many of the 892 are people gaming those systems.

well? Several major sub-contract companies I go to have EV for transport and tasks up to 3.5 tonnes. Very useful they are too.

Does that make milk floats which have been utilising batteries for decades to lower noise when delivering early in the morning, keep costs lower and provide services otherwise not available to elderly or sick people knobheads too?

Does it make the people living in the cities that benefit from all the concessions provided for EVs knobheads?

No, it's just people like you that provide links and derogatory statements about technology you know little about because it doesn't fit into your "Good old days" attitude lifestyle that are.. Perhaps the apprentices assisting the companies building them should be shouted at more often, or sacked for not clearing the snow in the car park so you can park your gas guzzler and given a thick ear to remind them who's the boss eh.....

Luddite Do keep up at the back, there's a good chap

I know that sometimes Adam refers to a spade as a shovel and not an earth inverting horticultural instrument but...

Electric vehicles in the main, not milk floats, around there they have a Petrol powered one wonder why?.

But there are still serious problems with implementing these the main one is the primary power system. Batteries, unless someone does invent one that is neigh on 100% efficient and has much greater capacity and costs and weighs sod all, will always be their great limitation.

Electric motor power transmission is excellent but this power source.

To hear misguided politicos wittering on about "non polluting" when the power is in the main supplied by coal and gas, the power generated conversion a not to high percentage, and then transmitted and stored with yet another conversion does indeed deserve the worthy comment Knob head...

I always wonder at the mentality of those who deride pollution free vehicles and still think that choking, smoking diesels are OK and we should have more of them and kill ourselves quicker.

My previous diesel (Honda 2.2) would give a cloud of black smoke if you suddenly hoofed it e.g. getting to speed up a motorway on-ramp. Current car (Audi 3.0) has a DPF and I've *never* seen so much as a wisp of smoke from it ... though, yes I've heard the horror stories of expensive replacements being required ... will have to see about that if it comes to it.

An EV is fine for 90% of "all" car trips made per year - fine for 100% of trips only in towns and cities. It is the odd long trips, which overall in a country is small, which requires some focus - and this keeps advancements down. The "poor" range extender in the Volt is giving a claimed ~60mpg with the car not running on the battery. So not bad. The Russian rotary vane engine range extender offers far more.

Note below, "90% charge in less than 5 minutes".

International Corporation, January 27, 2010 - Toshiba proudly announces that it has established US-based sales and technical support for its new product, the Super Charge Ion Battery, SCiBT. This nano-based breakthrough lithium technology is noted for its rapid charging capability of 90% charge in less than 5 minutes, long life of more than 10 years even at rapid charge rates, and excellent safety performance. The SCiBT product line will be supported out of the Toshiba International Corporation headquarters in Houston, Texas and the SCiBT team will focus on business development activities, battery pack design, prototyping, assembly, technical support, and service.

The SCiBT battery technology offers numerous performance advantages that make it an ideal solution for many of today's toughest energy storage challenges.

The secret is brake regen and supercapacitors/efficient batteries. The new Russian hybrid using the rotary vane engines range extender uses supercapacitors. Compressed air brake regen would have been feasible, and air is free, but R&D in supercapacitors and batteries may have pushed air into the background for now.

Coal smoke stacks can be controlled. Gas is very clean. So, 40% efficient from power station to socket. 80^ of the energy in cars tank is wasted, so

20% efficient. A battery wastes only 10% at most so 90% plus efficient. It does not take much maths to see the EV is more energy efficient from station generator to EVs wheels - as it stands RIGHT NOW !!!!

Clean up the towns and cities and its cascades to all over.

There is another problem here, namely that if a much higher density portable energy solution was developed it would have too much potential to be "unsafe". Whether deliberately or not.

You mean like a tankful of petrol or diesel?

Haven't seen a milk float for many a year. Once they were a common sight. But in any case a very specialist application. Travels a short distance with many start/stops. No other deliveries has the same pattern.

The former is the EGR system. Expensive as well, but not as eye watering as the DPF can be. Apparently there is a place in london that will drill a sodding great hole through the DPF and remap the engine as a "bodge".

My next car will not be a diesel.

Plenty of life left in the warranty yet, yes I've seen places offering to remove DPF and remap, not clear what this will mean with the new MOT regime, no doubt reports will crop up on forums if it's a problem.

IF the green faction hadn't pushed for Euro 4/5/6 engines we wouldn't have DPFs or engines that squirt extract of piss into the exhaust.

My off-roader is congestion charge exempt. It has a range of 700 miles and can tackle driving across Europe within a day and a half. Which electric vehicle should I be looking at?

Tanks of petrol are nasty, the vapour produced at normal temperatures will burn (explode) with a tiny source of ignition. Diesel has to be got fairly hot before it vapourises enough to catch fire. Starting from cold it doesn't even burn well on a wick of some sort. Biggest danger from a diesel spill is slipping on it rather than fire.

We do not, however, deem them to be too unsafe to use in millions of vehicles all over the worls.
