And here's the Connextras experiment
Added 2025-08-31 02:10:18 +0000 UTCYeah, just a little thing I thought to test based on a theory which was not correct. As per the new usual, you can watch it here or on YT at the link below.
I'm gonna do all the tidying up necessary (on this video and the other) before publishing in the morning.
Toodles!

Funny you say that. My fiancée keeps tons of desiccant gel around her printer and AMS to keep things dry. Then heats them up to reset them and use them again.

2025-09-02 14:07:22 +0000 UTCWith the desiccant dried air compressors at work, they use the waste heat from compressing air to regenerate the desiccant drum, apparently at a speed around 1 revolution per hour Manufacturer notes that optimum drying performance takes 4 to 5 hours at full load Though I forgot that yours rotates 30 times faster so it may be stabilised in 8 to 10 minutes This makes me think that you may be getting some inconsistent results as your desiccant may not be as baseline as you are thinking starting tests I am also really curious if there are dual type machines that use the vapor compression cycle to supply the hot and cold sides of the desiccant dryer for increased efficiency at the cost of complexity

2025-09-02 09:07:47 +0000 UTCI'm curious about the 80 second / 40 second standard. Assuming the wheel spins at a constant rate, that would mean that the ratio of adsorbing to heating areas should be two to one, but it looks like it's more than three to one. If the beige area was a quarter of the space, it would be three to one and it sure looks less than that.

2025-09-02 02:07:49 +0000 UTCI’d be curious to see how much water a bag of Lay’s Potato Chips will extract from the air. They go stale VERY quickly when you open a bag…. And they’re pretty cheap. 😃

2025-09-02 00:06:46 +0000 UTCTwo experiment variants: 1. Run at "half power", and run the rotaty motor on a PSU which lets you set 30 Hz, or less. Leave the rest as is. 2. Can you try that rotating one in a dry desert environment?

2025-08-31 19:32:21 +0000 UTCI could see this being turned into a really good 3d printer filament storage device. Odds are you could run the heater intermittently, not sure how one would sense when to run it. Maybe watch the moisture level in the heater exhaust and shut it off for a while when it drops?

2025-08-31 16:50:03 +0000 UTCMore pedantry: You label the experiment a failure, but I disagree. The experiment was a success in that you tested your idea (aka hypothesis) and got a result. The result was not the one you were expecting, but it's a result nonetheless.

2025-08-31 15:09:37 +0000 UTCIt might be interesting to take the plastic radiator to an actual radiator shop and see how much that experiment would cost.

2025-08-31 14:13:53 +0000 UTCGranted, framing experimentation explicitly around the formalities of the Scientific Method is cool and good actually! Which is to say if you’re doing educational content (which you are!), emphasizing the basics is important, particularly when it comes to science, given the war on science which has escalated astronomically in 2025.

2025-08-31 14:03:38 +0000 UTCNot to be too pedantic, but the thing you test in an experiment is an hypothesis, whereas a theory is what you what you develop based on the results of an experiment. (The reason this distinction shouldn’t be considered overly pedantic is that Creationists used to make hay over the fact that Darwinian evolution is only a theory, when theories are basically all you ever get from science.) (I wouldn’t have bothered with this correction if you hadn’t used “theory” in the context of being a thing being tested in an experiment. The hypothesis/theory distinction doesn’t really matter otherwise in colloquial usage.)

2025-08-31 13:59:54 +0000 UTCi think the only way to actually make it more efficient is to use a metal radiator to increase the amount of moisture condensation, it's currently made out of plastic, and plastic isn't typically known for its heat conduction efficiency.

2025-08-31 05:04:02 +0000 UTCNice experiment! I still don't understand why you'd get less water with this approach though. In my opinion, if you give the gel more time to absorb water by stopping the wheel instead of increasing its size, nothing should change. I think of it as emptying a swimming pool with buckets of two different sizes; in one case, you have small buckets and can fill and empty them frequently but the ammount of whater removed with each bucket is low; in the other scenario, you have larger buckets but it takes longer to fill and empty them altough with each bucket you carry away a lot of water and thus in the end the ammount of water removed should be the same. I am assuming that the heating element is powerful enough to completely dry the gel regardless of the amount of water it contains.

2025-08-31 02:42:37 +0000 UTCI love these experiments. Still valuable knowledge obtained even though it was different than expected.
