**It probably does. That merely reflects Toyota's unfortunate choice of IC
engine in their Prius. The concept is good, but the execution leaves much to
be desired. IMO, a MUCH larger battery, plug-in recharging and a smaller
Diesel engine would have been better choices.

The Prius is indeed merely an interim 'feel good' solution for a few bleeding
hearts.

When the REAL series hybrids like the Opel Flextreme (using a diesel engine for
efficiency when battery recharge is needed) come on stream the whole situation
will change radically and every motor manufacturer other than GM will be left
looking very stupid.

Even considered they might have learnt something from the EV1 ?

**Indeed. That VW engine is an impressive device.

The '3 litre' Lupo could do 100km on 3 litres of fuel.
http://en.wikipedia.org/wiki/Volkswagen_Lupo

And that was several years ago and not even a hybrid !

"The Lupo 3L was a special-edition made with the intent of being the world's
first car in series production consuming as little as 3 litres of fuel per 100
kilometres (78 miles per US gallon or 94 miles per Imperial gallon). To achieve
this the 3L was significantly changed from the standard Lupo to include:
1.2 litre 3-cylinder diesel engine with turbocharger and direct injection (61
hp, 140 Nm)
Use of light-weight aluminum and magnesium alloys for doors, bonnet, rear-hatch,
seat frames, engine block, wheels, suspension system etc. to achieve a weight of
only 830 kg (1830 lb)
Tiptronic gearbox
Engine start/stop automatic to avoid long idling periods
Low rolling resistance tires
battery location moved to boot for better weight distribution

During the period of series production of the Lupo 3L, Volkswagen also presented
the 1L Concept, a prototype made with the objective of proving the capability of
producing a roadworthy vehicle consuming only 1 litre of fuel per 100 kilometres
(235 miles per US gallon)."

I'm not sure that it is just efficency, but more startup and sht down
times. AFAIK coal fired takes 24 hours to start up, gas turbine minutes
and hydro seconds. so if you have the coal burning and the boilers
bubbling you want the generator to be spining producing electricty that
you are getting paid for.

This is the fundamental difference between baseload and peaking generation.
Peaking is expensive typically. Baseload is very cheap typically.

Certainly, rechargng a whole pile of electric cars during off peak would
give he coal station generators better return and thus higher efficency

How does it change their efficiency ?

It is NOT however worth the home owner charging a whole pile of batteries
atthe cheap rate and then runing their house on an inverter during the
day. Efficency in and efficency out, then cost of asset and deprecation
takes care of all that. <Just thought I'd shoot that turkey before it
got off the ground>

That would be just nuts.

**I'm pretty certain I could find a motorcycle with superior fuel economy
too. Additionally, that is not in stop-start motoring. THAT is what the
Prius is designed to do best. You seem to forget that the Prius offers
comfort for five people and reasonable luggage capacity. It is important to
compare apples with apples.

Not for turbo diesels, Increased efficiency over a narrower rev range
compared to petrol engines. Not a problem when mated with lots of gears or
CVT

**Indeed. Things are changing in that area too.
Not for a turbo diesel as I keep telling you.

**Ah, the old apples with oranges comparison. I understand it well.
My *average* is 6.0L/100km, including peak hour city driving. Why should I
care about Sydney peak hour traffic anyway? That's what public transport
is
for.

**It is also why many people buy Prius cars.
Nope *easily* out exelerates most cars in traffic without needing a petrol
bowser in tow!

**What is the acceleration from 0-100kph? The Prius is approximately 11
seconds. My own dinosaur manages it in around 8 seconds.
Thanks, I won't!


Actually designed for countries/cities different than our own.

**Nope. The Prius works extremely well right here in Sydney.

But mostly
just to get in on the developmental ground floor. Pity they haven't
climbed
any higher in the last decade though.

**They have, actually. Just not far enough.
And not even then! But you see it it pointless for you, just as it is for
*most* people in Australia.

**I disagree. Most people I see on the roads do not require huge load
carrying capacity, nor long distance ability. Some do, but most do not.
Nope, the Ford Focus and GM Astra Turbo diesels (among others) are far
more
practical in Australia than the overpriced Prius.

**Not around Sydney, they're not. The price of Diesel is far too high and
they don't provide sufficient economy for city driving.
And God help you when the batteries need replacing.

**What's the warranty? 8 years? I did some calculations and figured that I
could replace the batteries in a Prius for around AUS$1,000.00. Given that I
could manage it, I'm certain others could do likewise, at lower prices.
Toyota's battery price is just silly, of course.
GM had an electric car long before the Prius. The time wasn't right, just
as
it still isn't.

**I've seen interviews with the people who leased that car. They seemed to
feel that the time was right. They were not allowed to keep their cars.

I'm not saying that won't ever change however. Maybe then
the vehicles will improve, they certainly need to!

**Oh, we're just starting this particular journey into the technology. But
start we must. Personal transport using fossil fuel is doomed.
If you live long enough.

**Like I said: we'll see. 'Peak oil' has probably been reached. $10.00/Litre
for Diesel/petrol is not an unreasonable expectation within the next decade.
At those levels, electric cars will suddenly appear to be a real good idea,
despite the limitations (and they are certainly considerable).
No argument from me!


Ignorance of the total costs involved until too late, or simply a wish to
scare pedestrians? :)

**A desire to do their bit for the environment. At least, three of my
neighbours, who own Prius cars cite that as their rationale. I applaud them
for putting their money where their mouths are. The Prius is a very
expensive way to make a statement. They are certainly not under the delusion
that the Prius will pay itself back in fuel savings.

Could you please list that "revenue", then list all the money spent on
roads at federal, stae and local government level?
It will be very informative for you.

Yep, sure is. I suggest you try it. Make sure you include all motoring
related taxes, levies, duties, excises, fines, etc, both state and federal.
I have no real problem with motorists being taxed for other purposes than
roads, (although I do object to the ad-hoc nature of many of the charges)
but denying it happens is just plain ignorance.
I still remember part of the targeted bi-centennial fuel levy being used
here for a tram extension. So even when it's not supposed to go to
consolidated revenue, it still doesn't benefit drivers.
(OT. Trams must be the worst form of public transport invented IMO, and the
biggest cause of traffic congestion in the cities of those that have them,
along with indiscriminate on street parking)

Then there are the cross subsidies actually spent on roads, but mainly for
the benefit of freight transport. Car drivers help fund the free interstate
highway network, whilst being forced to pay tolls on many local roads. So
they could at least admit non-motorist consumers benefit from all those
motoring taxes, levies, duties, excises, fines, etc. etc,or get the
interstate freight off the road and onto the rail network where it should be
IMO! Or how about tolls on the Hume, and all the current freeways to bring
some semblance of fairness to the system.

My first change though would be to cut out fixed registration and CTP
charges, and increase fuel taxes, thereby making smaller or hybrid vehicles
and motorcycles a viable option as a second or even third vehicle, and
making those who use their vehicles more, actually pay more.

there are a couple of sticking points:

other road users. Perhaps a tax based on the 'agressivity' and road damage
of the vehicle is required.

Why? My car is directly comparable to a Prius in size, passenger/luggage
carrying ability, comfort, overall running cost, emmissions etc. BUT
performance is better, costs less to buy, no batteries to replace.
It's actually YOUR car that is a totally different category it seems.

**What is the acceleration from 0-100kph? The Prius is approximately 11

See, mine is less than that! (9.3 seconds according to the manufacturer with
a slightly more expensive model rated at 8.2 seconds with a rated fuel
consumption of 6.3 litres combined) You really need to see what is out there
before singing the praises of overpriced obsolete technology like the Prius.
My own dinosaur manages it in around 8 seconds.

So can *many* cars, at the expense of fuel consumption of course.
**Nope. The Prius works extremely well right here in Sydney.

Yep, if all you do is travel in the city, save your money and use public
transport. OR buy a motor scooter.

No argument there. Renewable energy sources and electric only cars will be

Not to mention delusional when there are far better options.
My beef is that the single biggest problem with the world is 6+ Billion
people, and yet those pretending to save the planet are often the same ones
screaming for baby bonuses, child care support, and a hundred other handouts
to encourage people to make the problem worse!
They are certainly not under the delusion

Me either, that's what you get with a no fault system. The bad drivers are
subsided by the others.
Yet,
my CTP insurance STILL rises each and every year. There needs to be a fairer

True, but at least a system that charges for the time you are actually on
the road rather than in the garage, would be an improvement IMO.
Certainly no worse on that score.

At least including it in fuel taxes does help, since the bigger the vehicle
the more fuel it will use.

Strawman. Where does the electricity come from at what efficiency ?






Grid losses are typically in the order of 6-10% alone AIUI.

And you're not going to replace all that coal fired electricity overnight.. The
only realistic option is a huge scale program of nukes. You have the uranium
AIUI. Result, the EV is currently LESS efficient than modern ICE based proposals
and is inherently inflexible wrt long journeys.

Pitifully simple.

They only sell electricity late at night for a discount because they
HAVE to keep the baseload stations running regardless.

It's merely a question of getting at least something for what they
have no choice but to do.

Make it popular and the price will go up. It's called 'the market'.

Come on, have you even done a rough calculations of what kind of load we
are talking about? I like to see you do some back of the envelop
calculations. Firstly, how much energy are we talking about?
Do you even understand the difference between baseload and peaking
generation ?

Without any calculations, how do you know what sort of load are we
talking about? As you say if you have to keep the baseload stations
running why
not put them to good use? Apart from heating people's hot water over-
night and street lighting, what else would you be using them for?
NO free lunch again you see plus pure EV ranges are pitiful. AND the
batteries take an AGE to recharge and last at best 5 years.

Graham

That's right they are talking about building the infrastructure to
support it. What's the difference between that any heaps of suburban
petrol stations across the cities? Batteries and solar cell technologies
are getting better. Finally when you say taking a long time to recharge,
what sort of time are you talking about? How about some calculations to
show that it is not feasible?

One more thing, if nothing else, we will have much cleaner air, at least
in the bigger cities. That has to be a good thing for people with
breathing difficulties.

Yes , it doesnt work in liqufied form.
Its only used that way for export.
Large ships with special insulated cryo tanks carry the stuff around
the world.
The local busses here run on CNG but its simply compressed as a gas
into hi pressure cylinders which are located on the roof of the bus.
There are some cars running around powered by CNG and there is one CNG
filling station near where I live.
Just looks like a normal petrol station with slightly differant
looking pumps.
CNG is a bit of a dilemma for Govts in how do they tax it.
Gasoline and LPG are taxed, but CNG isnt, or not yet anyway.
If you tax it , then the tax will have to apply to all CNG uses, as
you wont be able to stop people filling their cars at home of the gas
pipe.

purposes than roads,

That is the point, motorists ARE NOT TAXED for other purposes,
but are grossly subsidised out of general revenue by EVERYONE,
including non-motorists.

you Graham.

energy? Amazing isn't it?

Indeed !



No. I suspect an attempt to manupulate share prices with provocative media
announcements.



I believe the highest energy density types are the molten sodium and molten
salt types e.g.
http://en.wikipedia.org/wiki/Molten_salt_battery

Like the Zebra battery. One small problem.....
"When not in use, zebra batteries typically require being left under charge, in
order to be ready for use when needed. If shut down, a reheating process must
be initiated that may require up to two days to restore the battery pack to the
desired temperature, and full charge."

They ALL have to be kept hot i.e. molten to work.

Graham

And they are simply too heavy.
The lightest batteries at the moment are Lithium Ions which weigh
around 10 KG per KWH.
So for a range or around 150 miles you need 30 KWH , so thats 300 KG
of battery in your car, or the equivalent of around 4 passengers all
the time.
But its really all academic anyway.
History shows that people wont adopt new technology unless it costs
around the same or less than whats currently available for the same
level of performance.
So Evs will have to compete price wise with conventional cars for
similar performance, and so far thats just a dream.
Heres a bit of interesting info.
When Henry Ford invented his model T , it sold for around $300
which was approx 4 months pay at that time.
That would make a Model T cost around $4000 in todays money, not
far from what Indias Tata motors are aiming for . ($3800)
Electric cars will have to come down to around $20K or less before
there will be much interest, and currently you cant even buy the
battery for that price.

Heres an interesting question to ponder.
What gives the greatest improvement in CO2 reduction per dollar spent.
Solar Panels or Electric cars.
Why arnt Electric cars subsidised like Solar Panels are.
