Tbontob, I never once said it was safe. Everything I said about it is that it is not as dangerous as most people believe it is. This in no way says that it is not dangerous. You are indeed obsessing over one minor statement that isn't even a large part of what I have said. Go ahead and keep obsessing over it. I am through going in circles with you. You are not interested in amending your misconceptions, only in trying to make jabs at me. Nothing I say makes any dent in your stubborn resolve against me, so there is no point in continuing.

"I never mentioned the first post in the thread. I mentioned the first post I made regarding the hydrogen issue."

Fyron, you seem to post something then later post a clarification. Because this isn't what you said- it may have been what you MEANT, but you said "Why are you so obsessed with the first post? The first post is not the entirety of the conversation, you know." which could easily be taken to mean the very first post.

<font size="2" face="Verdana, Helvetica, sans-serif">Actually, you just said <font size="2" face="Verdana, Helvetica, sans-serif">leaving it at "the first post" rather than "my first post" (which is what you now seem to say you meant) - and they mean two very different things. Odd behaviour, for a person who is often empasising language. <font size="2" face="Verdana, Helvetica, sans-serif">Said: no, you didn't - specifically. Implied: yes, you did. You implied it so strongly on that first post of yours in this thread when you said <font size="2" face="Verdana, Helvetica, sans-serif">You almost outright said the stuff was safe. "nowhere near " parses identically to "far from" - thus you were calling Hydrogen far from as dangerous as people make it out to be, which strongly implies that it is safe. Granted, you later said it wasn't, but you also don't seem to be conceeding that you ever implied Hydrogen was safe. Further, Tbontob never actually claimed that you said Hydrogen was safe - he said you implied it, he said you gave the impression - he never said you said that Hydrogen was safe [edit] my bad - he did once towards the very beginning, which you seem to be obsessing over - but the useage of "say" was light enough that it could mean imply; a one-word slip, perhaps.[/edit]. Odd that you don't pick up on that, for a person who emphasises language and word meanings so much. <font size="2" face="Verdana, Helvetica, sans-serif">The first time you didn't use "not as", you used "nowhere near" which does imply that it isn't dangerous. <font size="2" face="Verdana, Helvetica, sans-serif">You don't seem interested in mending yours, either. <font size="2" face="Verdana, Helvetica, sans-serif">It would appear that the reverse applies as well, Fyron.

<font size="2" face="Verdana, Helvetica, sans-serif">Well as long as we are correcting everyone in this thread, I take a little poke at Geo http://forum.shrapnelgames.com/images/icons/icon7.gif

The ship in question was a rigid airship, not a blimp. Blimps are still very much in favor, while the rigid exist only in memory and advanced design papers. Of note on the Hindenburg is the fact that the gas was not grounded to the airframe, and the ability of low pressure hydrogen to store static energy was unknown at that time. So when the air frame was grounded, the gas would have been required to overcome the built in impedance of the gas bag before it could discharge. In doing so, it would have created a spark. Anyone who works with rotary wing aviation can tell you how much energy an ungrounded airframe can hold. So while the sabotage theory makes for a good story, it was in all likelihood an engineering short fall.

oh the humanity...

Well during the down time I missed about 4 pbw turns...

Re: OT__For All Tesco PBW Games Playing and hosting
 

I hesitate to join a thread that's degenerated into bickering already... but what the hell. Back on the Hindenberg, there has been some pretty convincing modern research on this. The conclusion was that it was not the Hydrogen that was responsible for the (intial at least) combustion. Apparently the doping agent used on the outer skin, in the right conditions, was highly flammable and this was what caused the disaster. I saw a documentary where they had analysed the old film and could demonstrate from the spread of the flames that it was the skin and not the gas that was burning.

As for the relative danger of Hydrogen gas - well, here's an anecdote for you. Back in chemistry class about 20 years ago, a popular (with the kids anyway) experiment involved producing a test-tube full of hydrogen. I forget the exact reaction involved, it may have been some kind of acid-on-iron-filings thing. Anyway, that little test-tube containing hydrogen was then ignited using a lighted taper, producing one hell of a bang and (sometimes, though I never saw it) busting the test-tube entirely. From that I have always concluded that hydrogen/oxygen reactions can release a lot of energy.

However, I had also heard the argument that Fyron puts forward that Hydrogen airships are not as dangerous as they are generally perceived to be. So, why is that? Does that kind of violent small-scale reaction just not scale up?

Did you know the the municipality had to inform itself in writing 30 days in advance that it was digging so that the municipality could determine if lines were buried there.
This did not happen.

There is a fine for this.

So I asked our mayor if the municipality was going to fine the municipality over this.

( The mayor lives around the conor so you can drop in and say hi. He makes a really good jerk chicken on the bbq )

He just laughted

As someone who works with Hydrogen gas, among many other gasses, I can say that both industry standards and safety practices as well as OSHA requirements do consider Hydrogen as very dangerous.

Slick.

Re: OT__For All Tesco PBW Games Playing and hosting
 

Compressed hydrogen is dangerous, yes. But, the Hindenburg and other airships have given the public a false impression that it is much more dangerous than it is. People will gladly get into a car powered by exploding gasoline, but will have great fears/reservations of getting into a car powered by exploding hydrogen, even though it is really not more dangerous than the exploding gasoline (as that is essentially how cars are powered). And no, not everyone would react this way, but a lot of people do. But the thing is, much less hydrogen has to be used as fuel than gasoline (and other fuels commonly used), so the net effect is that using hydrogen is not much more dangerous than other fuels in most applications.
