    I watched this. It was of interest to me because I must run two dehumidifiers in my house and they use a ton of energy. Unfortunately, this desiccant dehumidifier would use even more energy. Hoping someday someone figures out how to build a more efficient one.

    In the meantime, I think manufacturers need to build all dehumidifiers with a repeat cycle timer built in. I find it far more energy efficient to run for some period like 30 minutes till the humidity drops low — like 45%, then shut off for 60-120 minutes while the humidity slowly creeps back up until the cycle repeats. Most dehumidifiers work based on a humidity threshold and will constantly click on and off as the threshold gets crossed. In my experience, this uses a lot more energy. Being in a high cost state it is completely unaffordable.

      You should be able to pick up an old style timer plug for under 10 euro / USD in your hardware store.

      They’re a tiny bit fiddly to set up but given how power hungry those things are you’ll be saving money in no time.

      We have one around here somewhere. I’ll see if I can dig you out a picture.

      Internet was faster…

      Sounds like something that could be automated via home assistant and an esp32.

    Man, I fucking love watching this guy. He’ll talk about the most niche things and I love learning about it. He inspired a presentation I gave on how rice cookers work

        Short answer — the internal “switch” is held in the on position by a magnet. Magnets become much less effective when they get hot, and while there is still water in the cooker the maximum temperature will be 100C. Once all the water boils off the temperature quickly rises — but the magnets stop being able to attract the switch when they hit around 102 - 103C or so and release the switch, turning the machine off.

        So all has is a switch connected to a magnet next to the bottom of the pot. That’s it. Physics does the rest.
