Oh no, it will release hydrogen and water will form! Not that! Hydrogen is nowhere near as dangerous as people make it out to be. The Hindenburg and other dirigibles created a very bad impression in the public's eye about hydrogen power...

Last time I heard, hydrogen in a confined space with oxygen is extremely explosive.

And you do get water or rather water vapour:

2H2 + O2 = 2H2O

if I remember my chemistry of many years ago.

Close... It was the Hindenburg. Lindenburg (or was it just Lindburg) was the name of a pilot who's child was kidnapped.

Or so my garbled history recalls...

Yeh, I think you are right, it was the Hindenburg.

I think the reason the Hindenburg did not explode was because it was not in a confined space and oxygen was not mixed with the hydrogen.

As the hydrogen and the oxygen were separated, the burning essentially took place on the periphery and moved inwards as the oxygen moved inwards.

Also air is only about 20% (21%?) oxygen, it is diluted and the rate of burning is much reduced than if it was pure oxygen.

Fryon: and release a bit of heat, just incidently.

At the least it would be a heck of a lot more expensive to repair, heh.

Yes, Hydrogen combines with Oxygen to make water and release heat. If you have ever held a match near gasoline you may have noticed that gasoline tends to do the same sort of thing... (making water and carbon dioxide in this case). Fyron is still correct when noting that Hydrogen is not as risky as the public percieves it to be (bad risk assesment, at the time dirigible travel was probably safer than airplane travel which was still in its infancy). I would tend to argue that the Hindenberg got played up in the press at the time bc/ dirigible technology was backed by the Germans and German/US relations were on their way down in the run up to World War II. This misperception that hydrogen is horribly dangereous is unfortunately still with us.

you guys should go argue on irc sometime.

So now I am back on... And every game is due.

Sugar.

Yes, the Hindenburg was the hydrogen blimp that blew up. The Lindenburg was the giant blimp filled with moldy cheeze. (See how I tied all the threads together with that comment? ain't I clever? )

[Geckomlis]

Took me awhile to relocate this article:

"The Hindenburg was covered with a cotton fabric that had been swabbed with a doping compound to protect and strengthen it. Unfortunately, the doping compound contained a cellulose acetate or nitrate (used in gunpowder). This compound was followed by a coating of aluminum powder (which is used in rocket fuel). Additionally, the structure was held together using wood spacers and ramie cord; the furnishings were make of silk and other fabrics; and the skeleton itself was duralumin coated with lacquer. Added together, all of these made the craft itself highly flammable. In DiChristina's article, Bain was quoted as saying that perhaps "... the moral of the story is, don't paint your airship with rocket fuel."

I second that motion! And since only Tesco and I are there, the vote passes! You all need to drop by #se4 on gamesnet IRC network. You have no choice now!

It is explosive, yes. But not really so explosive to be more worried about hydrogen than other gases and liquids running through pipes (save things like water that don't combust ).

But not so much heat to be a great risk over other things running through pipes.

And I am still correct in the first part of my statement. I never said that hydrogen was not explosive, just that it is not as dangerous as many people erroneously believe it to be.

ain't I clever? )

Nope!
