But Hummers are greener than Hydrogen Fuel-Cell cars. I know because someone told me. And that someone was me.llafnwod said:
Environmental Warrior James Cameron Gives Avatar Cast Blue Hybrid Cars

And I suppose all the mining equipment and container ships run on magic fairy dust and fart rainbows...Physics Engine said:Friend of the environment are we James?
Here's where the nickel comes from for all those Prius batteries. Looks very green huh? The environment is thanking you for saving it Mr. Cameron... somewhere... I guess.
They certainly do fool the public, though...
BTW, for a good laugh, try driving through Beverly Hills and count the Priuses (Priusi?). You win when you lose count.
My thoughts as well. But, you must remember that the new special edition of Avatar just came out so...Celtic_Kerr said:
Personally I'm not convinced with Hybrids as of yet due to the matter of regaining savings on fuel costs depending on numerous factors like individual driving distances versus the (sometimes) high cost of the actual vehicle and inevitably the ability to save or at least break even after that initial investment. Some are actually on the right track to create an automobile that is competitive with its non-hybrid counterpart. Meanwhile others like the Chevy Volt[footnote]40 grand for a Chevy, as in the bottom General Motors line now? Glad I'm not drinking any milk...[/footnote], make me facepalm with its $40,000 price tag and really seem like more of a boisterous show like what Cameron seems to be attempting here.
Loved Avatar as a spectacle.
Loathed it as an over-preachy, shallow, retreaded version of Pocahontas repackaged for sci-fi fans.
Seriously. Everything from Grandmother Tree down to John Smith/Jake Sully. They couldn't even come up with different initials for the guy. BLARGH.

It's been repeatedly tested than in practice a prius does like 50-55 mpg, not the stated 65.
Most small engine diesel powered cars will beat that, for example the VW Lupo diesel will do 65.
So giving them all VW lupo saves the environment more.

The more this guy talks, the more I dislike him. He talks about Avatar like it was revolutionary in every way conceivable, when really it was just a special effects spectacle with a poorly executed unoriginal story. He needs to get over himself and next time he feels like being a pretentious enviroasshole maybe buy a car that's actually good for the environment rather than buying into the only marketing campaign that gives his own a run for its money.
Yes. When people like James start droping this kind of bullshit I just wanna go out for a baby seal steak.Calbeck said:
I bet the people who got one are just thinking "Oh shit. I actually have to fucking drive this or everyone will think I'm a dick."
Actually it wouldn't surprise me if most of them just passes theirs on to someone else in the crew that didn't get one that didn't get so much of the percentage take.MurderousToaster said:
Cameron is starting to really show his dickface. I loved the movie for the story and the part where it wasn't Fern Gully reimagined, but this is making me sick to my stomach.
Besides, a Prius, really? He may as well have given them Smartcars as much as taped 'I'm a Dork' on their backs.
Actually that stuff is probably from Top Gear. Perhaps not the most reliable source though.llafnwod said:
Ironically, you *MAY* actually be partially correct about this (though Hybrid Cars don't use this.).SilentHunter7 said:
ALERT: SCIENCE AHEAD!
Hydrogen Fuel Cells produce Water. Now, at this point people all think "hooray water. How nice and natural". However, did you by any chance know what the main 3 Greenhouse gases are?
Water Vapour
Methane
Carbon Dioxide.
That's the same water vapour Hydrogen Fuel Cells produce. That list is also in order of strongest to weakest. The Carbon Dioxide scare actually only deals with the third weakest Greenhouse Gas (though due to its larger quantities, it's more damaging than Methane. Still bellow H2O though). Anyone who knows a little about organic chemistry will know this, but when you're burning petrol you're performing a similar reaction to this:
C4H10 + [3]O2 = [2]C2O + [5]H20
The square brackets represent how much many molecules are being used or produced. As you can see, actions that cut down on CO2 have the added bonus effect of cutting down on H2O, but both of these are a problem.
Hydrogen Fuel Cells cut out the Carbon part and just produce water. Depending on HOW MUCH water they produce, they could actually end up contributing more to the greenhouse effect than fossil fuels ever did.
Of course, burning Fossil Fuels has environmental impacts other than the greenhouse effect, and using Hydrogen is much cleaner.
It would be interesting to see a study on just how much difference it makes, but I don't know any.
Funny you should mention that last bit. I take it you are wishing more people would look things up. The Prius doesn't use a lithium ion battery. It used a nickel metal hydride battery.llafnwod said:
Japan has been strangely tight lipped on the disposal costs of those batteries (typically lasting 5-7 years), Since the Prius has been sold world wide for under ten years, and only really reached a real level of popularity five years ago, we may have to wait a few years before significant numbers of the 900,000 Prius owners in the US realize they have to pay through the nose to get rid of their suddenly non-functional vehicles.
Much more interesting a viable battery replacement already exists, flywheels, and they have larger energy densities (by weight) then current chemical battery systems, produce far less waste in their creation, and would likely outlast the vehicle with only bearing replacement every 5-10 years required (and with some currently prohibitively expensive alloys they may never need replacement). If you think it's a pipe dream buses where used in the 50s that where powered by flywheels, and a vehicle was successfully tested in 97 that used a combination gas engine and flywheel system to power a vehicle. It's a technology worth revisiting, especially as NASA once again shows why the space program is important by placing best on future of flywheels for energy storage in space. Still it's hard to persuade a company to give up on a technology they have already spent billions developing and marketing to the public for a new technology that may not even pan out.
Oh, and in case you where wondering there are studies that show the total energy cost of a Prius and most other hybrids is actually higher then traditional "gas guzzler" vehicles. The "Dust to Dust" [http://cnwmr.com/nss-folder/automotiveenergy/DUST%20PDF%20VERSION.pdf] CSW study springs to mind, through it has a contested conclusion that the total energy cost over the life of a Prius is higher then the total energy cost of a Hummer, it does point out that fuel efficiency is not the full picture when it comes to total energy cost. Groups as large as the British goverment have been trying to get Toyota to release more information about the total CO2 production related to production of the vehicles without getting much in the way of solid data out of Toyota. Overall I would say people are justified in saying that the Prius probably has a much, much larger environmental footprint then your average person believes. At the very least they are no better overall then your average efficient gas vehicle.
