Electric cars a step nearer mainstream?

..and still emits filth from the exhaust and still 75% of the energy in the tank is wasted. Boy you are dumb!

Stop making things up.

There are lots of solution to stop wasting energy in vehicles and stopping them killing the planet and our lungs with the filth they emit.

That is encouraging.

I estimate something like 95% efficiency on the motors, and probably similar on the pack.

A normal drive would be an average of perhaps 10Kw average leaving perhaps a KW for heating potentially available.Since there are no combustion products, the pack heat could be simply circulated through the car by a small fan. Obviuosly for winter starts, there wouldn't be a great deal initially, but a 1Kw fan heater to demist and defrost and get the car warm would not be a huge drain for the few minutes until the battery warmed up. If on overnight charge the battery would likely be slightly warm, and it would be possible to have the car pre-warmed off the mains as well.

Indeed. Drivel by name, drivel by content, mostly.

Don't let the fact of Drivel's idiocy have a negative impact on the electric car though. With him its random as to whether the literature he gleans his 'facts' from is competent and correct or total bullshit.

Essentially he can, and should be ignored completely with impunity.

That's easy. Public transport is crap and an unusable replacement for the vast majority of vehicle miles currently driven.

Even if public transport was good, you would still have a major problem persuading people to use it since it is going to be hugely difficult to compete with the freedoms that drivers are now accustomed to. (i.e. A door to door service, in your own private air conditioned space, with your own choice of music, and no other people in your face to put up with).

Because the buses do not get you from your front drive to the supermarket. With no hanging about, and without the need to fend off the unpleasant people you find on them.

.

I wouldn't deny anything bad about the Priapus meself. A cross bred bastard and an abortion, merely produced to sell to the gullible for Greenie points (like Brownie points, but green).

Why it gets special treatment is beyond me. It should be taxed double.

What does 'outperforms' mean?

If it means that it goes faster I'm not interested. A Porche is an extravagent status symbol which wouldn't do what we demand of our Laguna Estate - which we use for fewer than 3,000 miles a year.

I think it might be some time before there will be an electric or dual powered vehicle which will meet our demands which is sad, we'll probably be dead by then. If there was one now we'd use it.

Our demands?

Capacity and being able to tow. Our lives would be less rich if we couldn't do those things but we'd survive :-) A Porche in the drive would be meaningless.

For the rest of our journeys we walk, cycle, scooter or bus.

Not everyone.

Umm yes.....

This is because public transport doesn't meet their requirements.

There are then two results:

1) People take their cars to town, which frankly is a PITA because of parking arrangements being so poor in most places; and so

2) They go to out of town retail parks instead.

What's slug-pace?

It takes at least that time to re-charge a driver - efficiently and enjoyably.

Speed isn't everything.

A big set of AAs[1] might be more workable. Go for a standard cell size that can be swapped out as well as charged in situ. That way you have go to a filling station for a cell swap, and they could slow charge a pile of them off peak. You could also slow charge at home etc.

[1] obviously not real AA cells - but some standardised size

I'm pretty happy using my Land Rover..

The only issue is finding garages with high fill rate commercial pumps so that I can fill it quickly. With 90 litres plus at a time, it takes a while with ordinary mimsy pumps.

When they're new.

Even with excellent servicing they are smelly in only a few months. I wouldn't inflict the particulates of a diesel engine on anyone.

Diesels don't have catalytic converters... petrol engines do and therefore emit more C02

What people want is actually somewhat unknown, and in the case of the USA at lest given cheap as chip gasoline, was easily supplied by bolting a bloody great V8 into a 1940's truck body, and selling it to end users at commercial vehicle taxation rates. But high gasoline prices are frcing rethink even there..

Over here people buy a lot of small cars..and these would be ideal to be replaced by something of not very massive performance, and fully electric.

The area that seems hardest to replace is the high mileage rep car. Big luxury cars don't do high mileage,nor do delivery vans, shopping trolleys, local busses, and the school run car, or indeed the majority of off roaders and sports cars. Its the *long distance* vans, trucks, coaches and rep cars that will be the hardest to replicate.

There may well come time however, when we see that any distance over

100 miles is better served by driving to a rail depot, and shifting a container n(or indeed the whole car, as is done with the channel tunnel) onto a train, rather than driving it there.

Seems unlikely given that the power of braking systems typically dwarfs that of the motive systems in most cars. You will only be able to recover at a rate proportional to the max output of the drive system.

Mechanical recovery into a flywheel might work.

Yup. and asthma one suspects.

For some reason they have never had the stringent (and carbon innefficent) exhaust cleanups applied to them that petrol cars have.

Domestically its a twelve hour charge overnight on cheap rate. Easy enough for those with garages and well within domestic supply limits.

For regulated car parking, again easy enough to add socket-in-pole charging meters.

Hardest one is on street unregualated parking. Poeple will have to find sopmewhere else to park their cars overnight. Oh dear. What a shame.

About 70 nuclear power stations by my reckoning, and a 3:1 upsize in the the grid overall. Howver tht would happen over a couple of decades progressively.

For purely political reasons. We need to be using more electricity, not less, as long as its nuclear and not fossil generated. Anyway, off peak its cheaper than oil, now.

You must be getting weak. I can carry a 2CV engine and box myself :-)
