A while back, I mentioned one of the exhibits I remembered from a childhood visit to the Los Angeles Museum of Science and Industry (now the California Science Center) in the 1980s:

…a multi-screen cartoon about energy sources and engine types called “The Water Engine.” (Each screen has a character talking up internal combustion, flywheels, mag-lev, electric, etc. I still quote the Peter Lorre-inspired fuel-cell scientist saying “And then…we burn the hydrogen!”)

At the end, the scientist tries repeatedly to ignite the hydrogen while everyone else watches nervously, then starts hiding behind obstacles or off-screen before the inevitable explosion bursts across all the screens. Then they all climb out of their hiding spots and agree that this would be really cool once the kinks are worked out, but it’s not there yet.

Brooke brought it up on Mastodon last month and I decided to go looking for it again. In 2017 there was nothing I found to show it even existed. In 2024 the only thing she could find at first was…my blog post from 2017. Which I’d forgotten writing. 🤦‍♂️ I kept looking, and found a brief note that it was later shown at EPCOT, with a link to a long-dead page that had been archived in 2002 containing some extremely tiny screenshots!

9 tiny cartoon screens in a grid: You can just barely make out a cowboy, a child with a large tricycle-like assembly, a football coach, a miner with a hard hat, some old, yellowed parchment with a sketch on it, someone carrying an axle with wheels, a large lab flask filled with water, an old man holding up a picture of a horse, and someone in a superhero outfit standing on a row of horseshoe magnets.
Rescued from a long-dead web page via the Internet Archive.

Adding EPCOT to my search eventually turned up an extremely sparse IMDB entry and…*drumroll please* someone’s home camcorder video of the whole presentation!

It does exist! It wasn’t a shared hallucination! The fuel cell scientist (who extracts the hydrogen from water, hence the title) does sound like Peter Lorre! He does indeed say the line that my family still quotes decades later! And it does indeed explode across the whole display!

The “Today’s Outlook” section of the California electricity ISO shows detailed trends and breakdowns of how much electricity is available from which sources over the course of the day, and both actual and projected demand.

You’d think demand would be highest during the hottest part of the day, but it’s early evening, when people are getting home and turning on their own air conditioners. Just as solar is fading.
