    If you want to see one in action, I found this: https://www.youtube.com/watch?v=sApyrDEXGAI

    Using this as a greenhouse vent actuator is pretty cool. It just makes so much sense.

    I'm surprised this page doesn't mention the automotive thermostat which uses the same principle to control the flow of coolant between the engine block and radiator in an ICE vehicle.

    Big Clive took one to bits some years back: https://www.youtube.com/watch?v=uPuvhnIoz2g

      What a treasure Big Clive is. Educational, entertaining, and zero of those YouTube cliches and clickbait that everyone hates. I don't think he's ever said "Like and subscribe" literally ever.

    I once had an interview at PA consulting where they asked one of those questions where they have "the answer" but their question isn't well specified enough to lead to that unique answer. They kept adding conditions, but I hadn't ever heard of wax actuators before. (I was like 19 or something - didn't get that job!)

    Objects like this make me think of grimdark (steam|diesel)punk works like the video games Dishonored or BioShock. It feels like there's a touch of occultism or corruption whenever one creates a device that exploits analog side effects to create machines in a closed, black-box package.

      I have bad news to tell you about your "digital" computer.

      I see what you mean, but it’s less the exploitation itself than its immediacy and legibility. It doesn’t vanish behind a million abstractions or complicated miniaturization processes but can be readily experienced and understood, like steam.

      On the other hand one might as well associate it with “solar punk”, especially when powered by ambient temperature.

      The second sentence also fits for field effect transistors and solid state electronics in general.

      In the spirit of grimdark steampunk, have you ever heard of pneumatic logic? I still see these systems operating normally in some older mechanical rooms, it’s cool to see them still working after 40-50 years.
