    Looking for the electron meme about having 1% mass and half the charge, found this, which I think is funnier.

    What he thought was H2O was H2SO4
  • Mary had a little lamb, it drank some gasoline, then wandered near a fire, where it since has not benzene.

    Mary had a little lamb, she thought to make it glow, but if 238 is 'good enough', then better is one more!... Now her school is a hole. And Mary is no more.

    Mary has a unique lamb, truly one of a kind, it's name is 'Singularity', and it can't see its own behind.

    Hamlet should have studied IC, because "2B /=\ 2B" is easily solved by C4.

  • About 10 years ago I did a deep dive on platinum use in fuel cells. Using figures for total platinum mined so far and recoverable reserves, and for the amount of platinum in a typical fuel cell for a small car, I arrived at the total number of vehicles that could be produced: ~100M. That's ALL the platinum on the entire planet.

    Without a better catalyst, hydrogen for passenger vehicles is an unworkable pipe dream.

  • Two chemistry majors walk into a bar. The bartender says to the first, "What can I get for you?"
    "H2O."
    "And you," asks the bartender?
    "I'll have an H20, too."
    The second guy died.

    I have a lot of problems with that joke. But I'm glad it's here anyway.
  • A higgs boson walks into a church.
    The priest says " you can't be in here, you have to leave!"
    The higgs boson says "but without me you can't have mass!"
  • North America has accepted Elon Musk's vision of the future for transportation, communications, environmental policy, electrical grids, space exploration, and digging holes in the ground.

    That is the joke. You already know the punchline.

    Other than that, all I can say is that if the Chinese, who have more battery EVs on the road than any other country in the world by far, are moving ahead with hydrogen research, then the question to ask is not "Why are the Chinese so stupid?" but "What do they know that I don't?"

    Toyota's all in on hydrogen too.  In short, hydrogen is a good battery for an electric motor.  And to pull off millions of cars, you need a cheap scalable technology.   Lithium ion ain't.
  • Proton Technologies. They invented hydrogen mines. And they are going strong three years after I heard of them. That's rare.

    That's a sad bit of info if true.  Not doubting you, just lamenting a fuel cell option with so much promise.  Balls.  Double balls.

    the real problem with using H2 is that it tends to be bonded to other things and it takes a lot of energy to free it so you can use it. it might become part of the solution, in some cases, but it isn't going to be a big player.
