    Talk about a waste of money.

    OK, a “spark” seems to be the culprit that ignited a hydrogen leak. (duh) Knew that in the 1937. But what caused the spark? Static electricity build up being grounded. You know how to do this at home. Cold dry day, socks on the rug, shuffle the feet and reach for a metal object ….ZAP.

    And it took 76 years to study this? And why?

    Are they sure they can’t blame that on Bush?

    Yet I remember a president who wanted to start building cars using hydrogen as fuel. Imagine one of those getting into a disagreement with an 18-wheeler or a suburban assault vehicle. And you thought the Pinto was a fire waiting to happen (yes, this did happen much more frequently and under much more normal conditions than the Volt).

    And “conservatives”, “the religious” and “evangelicals” still blame Jesus!! Muslims blame Mohammed! Then there are Buddhists and other folks who “blame” their “situation” on dudes who died centuries ago, but still have huge impact on lives today.

    I thought it was the coating on the skin, cellulose nitrate or cellulose acetate and aluminum powder (which is part of some rocket fuel) that was sparked by lightning or static electricity.
    Hydrogen flames are invisible.

    Buddhists not so much, trout.

    Does anyone else here know that the canvas cover on the Hindenburg was made gas-tight by coating it with a substance more flammable than gasoline? That hydrogen is lighter than air and therefore burned up and away from the passenger cabin? And that the gasoline-like substance is what burned the people? And that the hydrogen fuel tank on a car is every bit as safe as a gasoline fuel tank?

    No… I din’t think so.

    Hmmmm, interesting. Well, hydrogen may burn invisibly but the rest of that dirigible did not.

    Except Rockngolfer, he knew.

    “And that the hydrogen fuel tank on a car is every bit as safe as a gasoline fuel tank?”

    No, I didn’t know that. I thank you for your information. I was taught in school that hydrogen is extremely flammable, but did not know that it burned without flame. I suppose the outcome would have been the same, because once the hydrogen burned out, even if the skin did not catch fire, the craft would lose its ability to float, and come crashing down to earth. But I appreciate the info.

    Just as an interesting aside, today’s gasoline is not as volatile as you might think. I know it can explode under the right circumstances (especially under pressure) but I saw a guy flick a lit cigarette into a tub of gasoline, and it went out. Do not try this at home.

    High pressure, or liquified fuels like hydrogen or LNG are pretty tricky to handle safely. Also, it’s the vapor in a gasoline tank that isn’t full that is far more explosive than the liquid. If the U.S. had let Germany have helium from Texas for the dirigible fleet, like ours used, the accident wouldn’t have happened. Well, we DID lose our dirigibles to storms and other issues, but airships, especially for cargo, may well be making a comback!

    What happened to hydrogen fuel cell tech?

    Did the big bad fossil fuel guys squash that too?

    …and we’re still broke. What difference does it make Hillary?

    @I Play One On TV

    Because the gasoline cut of the third leg of the fire, oxygen.

    Could be, but just as likely the materials in the conversion process in a Fuel Cell are very expensive.

    Honda is still working on it with the FCX Clarity – available for lease in Southern California.
