Not a lot of extra weight is needed at all. First, keep in mind that Ford will
have the Topaz on the market, this fall.. based on Ballard fuel cells. This
entails a hydrogen tank, fuel cell, and electric motor, the heaviest parts of
your list above. Ford has stated repeatedly that it will be functionally
identical to a gas powered Topaz (as in, it will have the same range on a tank
of fuel, it will travel as quickly, it will carry the same load).
Compared to a hydrogen tank, the water tank is actually very light, since it
can simply be made of lightweight plastic. There is obviously no need for
the complex tanks that are used with h2. Since the water tank would only fill
as the h2 tank empties, then I suggest you keep your tank full. Keep in mind
here that we aren't talking about storing the great lakes in your water tank.
The electrolysis equipment isn't large, isn't hefty, and isn't expensive, nor
is a small compressor. The plumbing isn't either. Mostly likely, WITH solar
panels, I'd add ~ 150 lbs to your car with the h2 tank empty, and the water
tank full. With it empty and the h2 tank full, I'd add 80 lbs.
Considering the Topaz Ford is bragging about is supposed to be functionally
identical to a gas powered one (for range of travel on a tank, and speed and
weight it can carry), I really doubt the extra 150 lbs is going to make a
massive difference. I have 150 lbs in the trunk of my Jetta now. It helps keep
the rear end on the road in the winter ;)

Yes, but Ballard is the way to go. Every major car manufacturer has looked
into it. Buses in Vancouver and Victoria and New York are running on them
right now.

I do read the business section of the local newspaper, and I have watched the
President of Ford Canada on CPAC with the PM stating all these things, just
before he took a drive around the block with it.

P2000 Fuel Cell
Did you think it was possible to accelerate
from 0 to 97 kilometres per hour in 12
seconds while producing zero emissions?
Well, it's possible if you are driving the newest
member of Ford's ultra energy-efficient P2000
family zero-emission vehicle.
Ford's P2000 Fuel Cell is an advanced, hydrogen fuel powered sedan;
a midsize family car designed to achieve the performance of today's
Ford Taurus, going from 0 to 97 kmh (0 to 60 mph) in 12 seconds, and
produces 90 horsepower.
-----------------------
Is probably what you found, and it is indeed the car I was refering to. Sorry
I thought it was the Topaz, but obviously its the Taurus. I think that
"designed to achiecve the performace of today's Ford Taurus" explains the
statements I'm making.

Yup, they do. So does a gasoline truck that explodes, yet we use that today in
vehicles all over the place. Such a flammable liquid, and yet its everywhere.

Yes, years ago. I initially read about it 15 years ago. Times have changed,
and prototypes have improved into workable market models, that are used in
buses now, and will be used in cars this fall.

It is relatively safe. Haven't you heard about the tanks that the h2 are going
to be stored in? Why do you keep shoving that aside, and keep saying "Danger,
danger Wil Robertson!".
H2 WILL NOT EXPLODE AND KILL YOU BECAUSE YOU LOOK AT IT FUNNY.
Feel more secure about it? I know you're just arguing a point here, but why
aren't you worried about people who have a natural gas furnace, or stove?
They're obviously too inept and stupid to not kill themselves with them.
Natural gas is actually MORE dangerous than H2, since it disipates more slowly.

1) Take the same volume of gasoline, and use it to launch a rocket (leave aside
other issues). What would happen if something went wrong with the rocket as
did with the h2o rockets? Correct! It would explode. Its odd how cars aren't
exploding right now, all over the street. After all, a car is just a rocket,
right? Same concerns, same amount of fuel, same technology. BAH!
2) Erm, trying to liken gas and h2 explosive potential through volume is silly.
h2 is way _LESS_ explosive per volume than gas, since to compare volume you
have to compare the volume at the SAME PRESSURE AND TEMPERATURE. Gasoline at
one atmposphere and 20C compared to h2 at the same results in h2 loosing. H2
is in a gaseous state at 20C and one atmposhere, gasoline isn't.
3) How combustable something is doesn't equal the amount of energy you get from
something ONCE its ignited. The combustability of something only dictates how
easy it is to get it ignited.
4) Less hydrogen is consumed then gasoline to create electricity because of the
incredible efficiency of the ballard fuel cell. I suggest you read :
http://www.ballard.com/pem_intro.asp
and find out more about this fuel cell. Its not fire as you know it. Its not
going to explode and kill you.

Not at all. My link above points to a site that lists a car that uses h2, and
a SUV that uses the method you stated above. Considering this is round ONE of
a new technology (for mass market), I find it quite impressive. Ten years down
the road h2 power will change dramatically, as even more research and money
goes into it.

Which is why pure h2 is the way to go.

No, but it makes reference to the Taraus, a larger, more luxurious and more
powerful car than the Topaz. My mistake. However, it doesn't list anything
about mpg ratings, and since you're giving me mpg I would expect you are
refering to a US site. The American branch of Ford would never undertake
something like this, to much pressure from the oil tycoons, I suspect. Honda,
Germany car companies, and Ford (with a government grant) up here are going to
release models based on Ballard cells.

Fuelcell powertrains?! What are you refering to here. Fuelcells don't have
powertains. They provide electricity to electric motors.

They are completely and utterly incorrect. Ford has claims to the contrary.
I don't think you really looked to hard around ford's site to find any info on
the above, since this :
http://www.media.ford.com/article_display.cfm?article_id=4762
Lists a summary (although incomplete, and changed) of the press release done on
Parliment Hill. You can even see a little picture of our good old buddy, the
evil PM, driving around in it ;) Its interesting that they clearly (and I mean
*clearly*) stated that these vehicles would be out for fall 2001, and now it
states 2004. Perhaps the President of Ford Canada meant "some ballard powered
vehicle" instead of the Taurus based on. No matter.

Electric cars aren't just a dream. The prime minister has driven one around
Parliment Hill. That shows a massive difference from "Just a dream" to
"Designed, developed, planned, and built". This is a VIABLE, USABLE car.
