9/15/2002: Peugeot "fire car"

Re: 9/15/2002: Peugeot "fire car"
So...let me understand....the car makes hydrogen (from something)...for the hydrogen fuel cells. Then it needs oxygen to react with the hydrogen to make electricity. Unless the air is too smoky (yeah, sure...if the O2 level is too low to burn hydrogen powering your firecar is going to be the least of your problems. ). So reacting the O2 with the H2 makes....um....water. And electricity.
I suppose it make the hydrogen by electrolysing the water exhaust . :-) Ah, the French!
"So you see we feed the rats to the cats, and the cats to the rats, and get the furs for free!"
The real humdinger among the concept vehicles, though, is the H2O. Let's check this one out carefully: a rather snazzy-looking fire engine - yes. Ladder on the roof - yes. Water the theme - yes, not just in the context of spraying it over a blaze, but also because the H2O has a fuel cell powertrain, with modest amounts of water being almost the only thing in the exhaust.
Actually, Peugeot uses the expression pile à combustible, which is the (rather rude to Anglo-Saxon ears) French version of fuel cell. Hence the name of the Taxi PAC concept unveiled last year.
The H2O is a step forward in design, though, able to generate fuel in "real time". The point of installing the latest system in a fire engine is that if a vehicle of this kind is working in a smoke-filled environment where there's little or no oxygen, then the oxygen needed for operating the fuel cell can be taken from a tank on board. The H2O also has on-board breathing equipment for fire-fighters to use. </blockquote>
And here's another Peugot concept fire car:

I think the second fire car is more feasible.

Re: Fuel cells
Obviously the purpose of the ladder is to make it look like a firetruck. Without the ladder it looks like a cop car...or perhaps a cryogenic ambulance. :-)
Reading the press on this gadget, I don't think there's any connection between the water tankage and the fuel cells, despite what's been said. I think it's just a fuel-cell car witha water tank on the back.
There's a lot of "concept cars" that can't even be driven. Most of them show up at car shows and are displayed on a turntable with Jane Jetson leaning on them. :-)

...Jane his wife!....
Now that I look at it again, I think it looks like an autoclave.

If this is serious, then its real value is the ability to arrive quickly, and operate right up next to a burning building. Get the doors under control, and the people out. The short ladder and low-oxygen ability seem to confirm this. The rubber tires, on the other hand, don't.

I bet under all of that silly exterior, you will find a standard golf cart chassis.

An interesting thread going here, but one question eludes.

uh, i know nothing about hydrogen vs. gasoline, but to me it seems no worse than driving a gasoline powered vehicle to a fire-besought building.

Hydrogen: not just for breakfast anymore
You can't really compare the Hindenburg with the "rescue Le Car"
