And radiator? and starter motor? and exhaust system? and fuel pump, and mountings for all those, and ancillary pipework?
Add 50kg
And costs ten times as much per mile on fuel to run.
Current lipo technology is about 185Wh per kilogram.
pretty much the same as an electric would be, then.
The one I calculated;-) T-zero is not far off that.
Which is no doubt why MotoRail is a rapidly dying service.
Municipal and railway station car parks could be used as re-charging zones... like when you go to a campsite with a motor home or caravan, there are generally two rates, one for a straight pitch and another higher rate for services.
At least I'd feel I was getting some value from the pleasure of having to pay £500+ for my car to sit somewhere for 8 or 9 hours while I'm away at work.
No performance difference at altitude on electric propulsion.
Of course, hopefully the run down will charge the batteries by regenerative braking for the run back up ;-)
Public transport can not do what a private car can: we may have to go back to it, but not without a struggle.
I remember using public transport exlusively,. It took all day to get from Surrey to Devon, and involved a lot of strenuous lugging of luggage between various platforms. In a car, its about 4 hours door to door, that public transport never achieved.
Public transport constrains where you can operate from as a normal working person. I remember when my car broke, missing the only bus there was, and being 3 hours late for work.
Now I agree that we should try not to commute at all, make more use of public transport, and, indeed, its a fine thing when it works for you, but it is exrenmely inflexible. And not a cure all for all trips by any stretch of the imagination.
The extra time it takes might be the death of you when you need to get to A & E. Strangely the early adopters of small cars in the 50's were (amongst others) doctors midwives and district nurses...
That is possible, but you need to swap the lot, and at 250kg or more, its not something you can tuck in your pocket on the way from the till..
Its possible, but pretty expensive to make a fully electric 4WD, which sounds like what you are after. A sort of electric land rover.
There are of course a lot of advantages - full 4WD with a motor on every wheel and instantaneous torque transfer to the wheel with grip without much need for specialised drive train control.
All the weight low down in the battery pack, and keeping the electrics dry through a wade is probably easier than keeping air intakes and oil filled transmissions dry.
The actual car weight is not such an issue with towing either. You are not looking for rocket like acceleration - steady torque is very much what an electric motor gives you. Given the actual weight of a Defender, you could put a pretty hefty battery in its pretty light body..and still be no worse off than it is now, weight wise.
Actually leaving super capacitors aside, electric motors have good characteristics for this. Its not hard to make a motor than can have a burst (say 30 second) heat capacity some several times its peak continuous capacity. If you wind for optimum efficiency at cruise (which you probably would) the peak capacity is dominated by copper resistance heat losses. How much power you can absorb (even at not hugely good efficiencies) is really about how hot you can allow the motor to get. there is usually enough thermal mass in there to give you a half a minute of extremely high power - in OR out.
It is in fact ideal for road use, where mostly you are either stop starting at low power, or cruising. The extremes of acceleration and braking are for most drivers outside a race track, only occasional things.
The more you delve into the physics of BEV;'s the nicer the whole thing looks, bar the one bugaboo - that big battery.
I will certainly never be one to say that BEVs will ever equal IC engines in terms of sheer racing car performance, or range per weight of fuel/battery. They wont. You wont see battery powered airliners either - not with lithium anyway,although its doable (and has been done) with microlights.
That is not the point. The point is are they good ENOUGH, coupled with non fossil generated electricity, to replace a *substantial* number of road cars, and here I maintain that they are just about good enough, and will be even better shortly.
Personally a 150 mile range small electric car able to top 80mph and plug into an overnight socket, would be good enough for 95% of all my current motoring needs: I'd still keep the camper for what it does, and the land rover for when off road is needed, but they would simply not get used on a daily basis.
Frankly, with just 50 mile range, that would do ALL the shopping trips - about 50% of what we do.
If someone offered me such a car with suitable guarantees on the battery life, and at less than £10k I'd probabaly buy it on the spot.
I don't think its needed. I think the motors could easily cope with the peak powers..the battery should be able to cope also.
Quite: we try and avoid towns altogether, since there is very little in them of any interest whatsoever these days.
One or two have been made like this with encouraging results. Your idea is have nuclear cell in the car - such is snotty unis.
is it?
It certainly was hugely more expensive than the ferrys last time I used it. I was in a hurry and the hovercraft had vanished..
So I doubt its a technical things: simply the way its priced.
It was certainly a good way to do the crossing: just expensive.
I gave a link.
Not in London as they have filters. Diesels busses shake like hell on idle. The sooner they are electric hybrids the better.
You haven't a clue how it works! It is brilliant. A seamless quiet drive - worth buying for that alone. Mine gets 60-65mpg in London. Fab! They are everywhere in London, The place is swarming with them. Swarming.
"Mary Fisher" gurgled happily, sounding much like they were saying:
Dog slow. Maximum 30mph, and acceleration that would be outstripped by a glacier.
It takes about a minute for the passenger to swap seats with the driver.
Speed.
It also has zero emissions and a super smooth seamless ride. Fab!
Hybrids are availabe to suit your needs.
It means he hasn't got a clue.
The Natural Philosopher gurgled happily, sounding much like they were saying:
Can your local substation cope with every house it supplies pulling so much extra current?
Again, can substations cope?
Anyway - if 12hrs is only giving you 50 miles range, an hour on a meter's barely worth bothering with.
Congratulations, you've just waved your hand and removed a very large percentage of urban residents from the equation.
Quite.
Oh, well, that's OK then... Just remind me of the timescales being talked about for the couple of nuclear power stations we might one day get round to building? Then, of course, there's the political implications of building even those couple, let alone 70 more...
Well said Mary .
"Doctor Drivel" gurgled happily, sounding much like they were saying:
...and still you miss the point more than slightly...
I do wish you'd stop referring to yourself in the second person. It's very... odd...
