  • I need to correct myself here and get more specific. It’s not only about what generates the electricity that powers the hydrogen extraction/isolation. It’s true that the current electrical grid is powered by a mix of activities that includes burning a lot of natural gas.

    But it’s also true that the current cheapest (and therefore by far most common) means of hydrogen production is steam methane reforming, where the source of the hydrogen atoms is natural gas. And the byproducts are some carbon monoxide and dioxide.

    In short, achieving truly green hydrogen production would require not just a green energy source but having that source be so inexpensive that it would be cheaper to make the hydrogen by electrolysis of water instead of by reforming methane. I don’t know enough to speculate how difficult or likely that will be.



  • I’m glad they at least mentioned, for those who read far enough down the article, that ultimately it’s powered by burning natural gas elsewhere to charge the hydrogen fuel cells [edit: please see my own response below]. I wasn’t sure if the AP had reached that level of ecological transparency/honesty yet so that’s good to see.

    Someday when California’s energy grid is 100% renewable this type of craft will be an amazingly clean way to get around. … Unfortunately it’s not too likely that we will ever see that future before the global economy and most present political structures collapse.






  • Based on having read this same SFGate article about five days ago, I made an online appointment for a booster shot at a Safeway store’s pharmacy, semi local to me in San Francisco. My previous booster was circa last November so it had been more than six months, and the recent news stories about a surge of covid detected in the city’s sewer outflows and also a general rising wave of cases locally seemed to give good reason to stay on the six month program rather than wait until it had been a year.

    The appointment was easily made online, but the pharmacy telephoned me and told me their advice was to just wait closer to a year unless I was over 65 or immune compromised. Neither applies so I cancelled the shot.







  • Ouch. I read this and followed links to read numerous other posts of his. Seems spot-on in his analysis and entirely parallels what I think and feel about our world. I’m struggling to avoid sheer terror in addition to the already present crippling anxiety and burnout. The only comfort, much of the time, is that none of us are truly or purely alone in all of this. The catastrophe surrounds everyone we know, regardless of whether their personal circumstances have yet broken down to a degree that allows them to witness it consciously.



  • When reminding or teaching the younger community about George H.W. Bush, let us not forget to mention that when the US elected him, it elected the former CIA director to the presidency.

    A supposedly democratic Republic elected its own chief of secret police to lead the executive branch of government. Somehow even at that time most Americans didn’t seem to be aware of that glaring fact, and far fewer have seemed to realize it ever since.

    And then the country went on to elect that guy’s completely unqualified son to the same office less than a generation later. /facepalm
