    How do the trucks even stay on the ground?

    Ok, now. Hands up everyone who knows where they mine helium from. :)

    Most helium is found mixed in with natural gas. It is a limited resource, since there is only one mechanism for replenishing helium, and that is alpha radiation decay. An alpha particle is two protons and two neutrons, which is a helium atom nucleus. If it manages to acquire a pair of electrons, it becomes a helium atom.

    That would explain why my farts gravitate upward… )<;

    Huckleberry: Biogas contains methane and hydrogen, both lighter than air. Other components are carbon dioxide (moderately heavier) and hydrogen sulfide (significantly heavier and the source of the stink). It still totals slightly lighter.

    Methane is part of what makes up a fart. It can also indicate life on other planets.

    Night-Gaunt: The primary part, it is still crude biogas.

    Wasn’t it somewhere in Utah? Or kept there as some strategic reserve. I read some article about just how limited the supply actually is and how the US stockpile is being sold willy-nilly these past few years.

    Actually, masterskrain is right; most of it is mined from Texas, with a bit from Kansas and Oklahoma. The stockpile is in Texas as well. But you are right about the stockpile being sold off — it was a Congressional decision in 1996 to sell off the whole stockpile by 2015, apparently because congresscritters think there will be an endless supply of it to be fractioned from natural gas. It’s a stupid thing that will come back to bite us in a few decades, considering how much of it is being wasted.
