*yawn* Mazda had the RX-8 running on hydrogen like, four days after it came out. Also, H2O is a greenhouse gas.

I wonder how they solved the whole exploding hydrogen gas tank deal...

Honda had a production CNG civic a while back... no exploding tanks there either.

I think Chad is referring to the unstable nature of Hydrogen and how it would do in a collision.

Yea, Liquid Hydrogen and Natural Gas are the same. NOT.
- .RJ - 09-13-2006
You're still dealing with a sealed container under extreme pressure.... the risk of the fuel "tank" rupturing are is the same in both circumstances. The consequences of exploding liquid hydrogen are far more severe, but either of them will probably launch you halfway to the moon if they let go in an accident.

Heh! NOT! I havent heard that for like 5 years. But yeah, I'm unimpressed as well. Who gives a shit when you're still running on gas for 75% of your trip. If those numbers had been reversed, then i'd have been impressed.

hydrogen is so light that most likely it'd evaporate before anything really went boom. not to say its not possible, but as RJ said, its a tank under pressure. you could be carrying scuba tanks in the back and have the same result

Scuba tanks arent at 30,000 psi.....

we've come a long way since the zeppelin. i've worked a lot with the fuel cell guys here and there's a much greater concern about being able to store enough hydrogen than it blowing up in an accident.
as far as the scuba tanks go, i dont know if they're filled with just oxygen or with nitrogen and oxygen, either way, they are several orders of magnitude heavier than hydrogen is.

This is true, however if the fuel storage tank/cell is lets go, you are f'ed in a bad way. It wont just "evaporate and go away".
- Maengelito - 09-13-2006
depends on the wreck. it doesnt just spontaneously combust. you've gotta be driving a car thats already on fire or really hit the tank in a violent way for it to reduce you to a crater in the road. and putting a composite hydrogen tank on the front or back for use as a bumper would jsut be absurd.

It would reduce accidents, thats for sure!

rofl - i think people would die of a heart attack if they were driving and saw they were going to collide

ha, i love that picture Rex
mythbusters did a bit on how possible it was for the guy in Jaws to puncture a scuba tank with a bullet -- to blow it up and kill Jaws. it's pretty damn hard to bust one of those tanks.
