What causes a battery to EXPLODE!

[Flashmn]

For those who were reading the thread on the strange idea on converting water to H2 and then combusting it in a standard engine, here is another example of how explosive hydrogen really is..

The hindenburg was filled with hydrogen, worst catastrophe in the zeppelin era.

then you wonder why they had such an issue with the hydrogen fuel cells being unstable. I'm scared to see what would happen to one of those buses they have around the states that are hudrogen powered if it got in a horrible accident

Well it is volatile, thats the thing, kinda like gasoline, doesnt take much of a spark to light a gasoline leak into a fireball. The containers for the hydrogen are quite thick, so they'd rather bend and dent than bust or crack, also they're placed in such a way in the vehicle that its not it a great risk of being damaged in an accident.. Besides hydrogen and LPG powered busses have been around for a long time now and I for once havent heard of a fueling related accident.

Problem with the hindenburg was the mass of the hydrogen, plus the fact that the outer skin was cloth, and the chemical to preserve it was made of such materials, that a static spark would ignite it and well, you know what happens next.

Also with the buses... they are huge it's a friggin bus, there is no way to prevent hydrogen from exploding in something like a civic in some of the accidents I have seen where there is just about nothing left of the car. You would kill the people in the car, the person hitting them and people standing withing a certain radius because of flying shrattnel

Sure there is, for example the gastank in a car is in a relatively safe place, in a crash, its not usually the gastank that breaks and leaks, its the fuel lines up front/under the car. Plus busses are bigger, so they need a bigger tank for hydrogen than a civic. Your imaginenation is playing tricks on you,

[freakinbox]

I understand that. But what I am saying is try preventing something like this from exploding with hydrogen in it. IT;s alot less stable than gasoline...



or how about some pics of when a drunk driver hit a civic and riped the rear end off, which would either take the take with it or rip it in half.

like how you missunderstood me when I said "just about nothing left of the car" I haven't a clue...

Wow where did the top half of that tree go...

I'm sure they would have thought of that in a fuel cell car. The Tanks in an LPG Car can withstand a semi hitting it at 110km/h (apparently). LPG Is alot more volatile than gas too.
