I can't stop thinking about this photo...truly an awesome encapsulation of the political and aesthetic economy of early 20th c. Los Angeles. This is a 1939 shot of the MGM backlot in Culver City.

"Clean" is a massive stretch here, true only if you wrap your mouth directly around the ferry's exhaust vent.
The article acknowledges that SF's ferry H2 is grey - i.e. heavy CO2 emissions in manufacturing! The article doesn't mention how H2 gets to the ferry: via diesel truck.

Ok I have to issue a very important correction, and an apology to the Germans: The world's largest electric vehicle is the Bagger 293, which is both a bit larger and way more evil-looking than Big Muskie.

The Trump regime wants to hide the threat of climate change from the American people. I believe they're going to fail at that. I know I've never felt so motivated to shout about that threat as I do now.
Participating in the NCA was a great honor, and suspending it is a crime - but the work goes on!

🤔I wonder if there's anything new about the relationship between SpaceX and FAA lately that might be worth mentioning...I seem to recall something, hazily...

A belated photo from an after-work protest last week. Rallies and protests aren't sufficient, but they are necessary! A woman leaned out of her car window to shout to me that she didn't believe anyone cared until she saw this 300-person crowd. This is how we build capacity to force a change.

This is not only very stupid - it's also the exact same logic that led Merrick Garland to slow-walk Trump's prosecution. These people have stepped on this rake again and again and again over, since at least 2000. There are only a few remaining ways to explain their refusal to learn...

A good ex of how far US train service has to go: My train from San Jose to LA - the only train of the day - is cancelled. Amtrak offers no alternative for anyone at the 9 stops S of Oakland. If you want a refund, you've got to request one yourself. If you want to fly, there are dozens of options.

Taking gas out of burn zones and high-fire-risk neighborhoods removes a flammable, explosive fire risk - one that likely played a role in making the LA fires worse. There's evidence of gas fires all over the place - in coming months, we'll hopefully learn more about the role gas played. (8/12)

Castaic is the 4th-largest pumped-hydro energy storage facility in N America and a crucial part of LA's electric system. As I wrote during a previous round of fires, climate-exacerbated disasters are making decarbonization harder.

Utility mutual aid - and the tremendous effort and sacrifice that utility workers pour into it - has always been amazing to me. A glimmer of the type of solidarity that could be possible if we structured our utilities differently.

Here's the Getty Villa (large rectangle near bottom right is the peristyle) sometime earlier today. Hoping the firefighters deployed around it stay safe and succeed.
