Talk:3109: Dehumidifier

Having network access can have some use for a dehumidifier, e.g. to remotely set the target humidity level, or get notifications when the water tank needs to get emptied. But having devices that depend on a specific app or a vendor-provided remote service risks having a useless device after a while ... --134.102.219.31 13:19, 30 June 2025 (UTC)

Humidifiers typically have a physical control to set a target humidity level, and even the most basic models turn off when the water tank gets full. Since humans can't really tell the difference between 40-60%, which is the range of most humidifiers, there is no need for a remote control to change the humidity levels on a machine. As for the water tank, regular use of the humidifier will teach the user about how long it can run before turning off and needing to be emptied. 136.62.110.93 (talk) 13:58, 30 June 2025 (UTC) (please sign your comments with ~~~~)

Though there might be a device that attempts to do both jobs, note that this is a dehumidifier (as you functionally refer to) and not necessarily also a capable humidifier (as you namechecked it). 92.23.2.228 17:53, 30 June 2025 (UTC)

uh, I forgot the leading 'de' . we're currently dealing with a semi-functional a/c unit in our business warehouse/office space. having to keep running the DEhumidifier to keep the temp reasonable during work hours. not enough condensate capacity to run over night, so it shuts off after about 10-12 hours. at least it runs on simple mechanical controls with no reliance on wi-fi 13:40, 1 July 2025 (UTC)

i had a good laugh at this comic, as i am designing dehumidifiers and they include wireless connectivity.....but there are reasons for this. But is more for monitoring, like e.g. in a water damage case the resoration company can see if the room is dry without having a technician drive to the location.

this comic will end up on our wall, together with xkcd:242 The Difference--

"if they discover a new kind of water" - There are several varieties of heavy water (common Hydrogen deuterium, tritium; common oxygen, various other isotopes), not to mention several [wiki:Phases of ice|phases of ice]. 64.201.132.210 20:31, 30 June 2025 (UTC)

I restored the part about phases of ice, because dehumidifiers do deal with ice (when icing up, and if the ambient temperature gets low). Mostly put it back because I thought a mention of ice-nine would be fun. 2600:387:4:803:0:0:0:B2 20:42, 30 June 2025 (UTC)

It's made of the same elements, but it isn't water. BunsenH (talk) 02:29, 1 July 2025 (UTC)

better patch that hole i made with hydrogen peroxide.--me, hi (talk) 21:49, 2 July 2025 (UTC)

Hydrogen peroxide is not to be confused with Dihydrogen Monoxide --134.102.219.31 11:30, 1 July 2025 (UTC)

Ice-nine is mentioned once in the trivia section. Did the user that added that mean to say ice-IX, were they unaware that ice-nine is fictional, or was it meant to be a joke? I thought that any "jokes" in the explanation were supposed to be technically factual, such as adding [citation needed] to a plainly obvious statement. Please forgive me for asking this stupid question. 47.14.13.170 01:22, 1 July 2025 (UTC)

Yes, it's supposed to all be factual. I've updated that. BunsenH (talk) 02:29, 1 July 2025 (UTC)

I just mentioned acoustic-based/light-based attack vectors and that patches might circumvent them. I've heard of them used against other devices, but never against a dehumidifier. Citation needed? 181.214.218.75 17:36, 1 July 2025 (UTC)

NOTE: water molecules do NOT exchange hydrogen ATOMS. atoms contain both protons and electrons. even your reference states that water molecules exchange PROTONS, not atoms. 2607:fb90:8a91:4e30:3c86:6f12:78c6:fe52 (talk) 00:30, 2 July 2025 (please sign your comments with ~~~~)

Does it at least support water conservation? StapleFreeBatteries (talk) 06:06, 2 July 2025 (UTC)

It probably supports water conversation, at the very least. 92.23.2.228 18:18, 2 July 2025 (UTC)

Improving the functioning of a dehumidifier does not require a new type of water. It could for example have a variable speed motor and prop-expansion valve. It is impossible to explore the full range of possible operations, so continuing engineering may be able to find better ways to operate the hardware without alterations. I worked on industrial equipment; we would routinely rollout software upgrades that would tweak a few percent improvement in installed equipment. 76.180.44.2 16:35, 5 July 2025 (UTC)

I can't make much sense of the new "Yet there is a method" paragraph. It seems to be saying that if programmability was added to absolutely everything, stuff could be done with it, but probably not very much. It's kind of like saying that if vitamins were added to absolutely everything, you could get some more nutrition by chewing on random objects in addition to the food you eat. It's a somewhat weaker argument than the usual "citation needed". BunsenH (talk) 04:07, 7 July 2025 (UTC)

That's the only idea i currently have about benefits of Wi-Fi in dehumidifier - it has no benefits for it's intended function, but does benefits for it's undocumented functions. Such smart devices can work as weak-ish computers with programmability; not very much - but they're already in your house, so you're getting that as a bonus - and you likely have many such devices in home, so they could be assembled into actually strong computation network. --SMGmsgsgd (talk) 13:45, 7 July 2025 (UTC)

I'm still not seeing it. Exactly the same argument could be made for adding computational power to anything: shoes, printed books, squirrels, bananas, etc. It isn't an argument for adding such abilities to a dehumidifier in particular. BunsenH (talk) 18:16, 7 July 2025 (UTC)

I just think it's all rather irrelevent, that bit. Some (separate) instances of what uses a wifi (or mobile-internet) connection could convey, and perhaps how they can be subverted, managed to get rolled into this. But some of it seems to be aimed at subverting the owner's expectations, some aimed at subverting the manufacturer's intended uses, etc, and all it really shows is that something that probably doesn't need an internet connection and reprogrammable firmware probbly would be best off without it. The paragrah has grown, admittedly with my own input (or corrective edits) as two parts of that, and probably could do with a good looking at to make sure that it has a more focused message. Or is perhaps split up into several seperately more focussed paragraphs that each is more narratively self-consistent. OTOH, I'm also not sure that anything would be lost by deleting it, perhaps remembering some few aspects of it as minor edits to other bits. 92.23.2.228 18:50, 7 July 2025 (UTC)

By the Numbers

Is anyone intrigued by the sheer numerical properties of the ordinal comic numbers themselves? This one, for example, is a prime number: 3109 is only divisible by itself and 1. I would be unsurprised to learn that Randall adds a layer of meaning based on significant or unusual sequence numbers. Has anyone else tried to keep track or decode such things? As of this writing, the next "Prime XKCD" will be 3119. Elizium23 (talk) 08:48, 12 July 2025 (UTC)

There have been notable number-related comics (or absence, in the case of 404), so there's always going to be some cases of playing to the number of the comic (or not).

But 3109 is the 445th prime number, and I doubt that such a numerical significance has been designed-in/easter-egged to many (if any?) of those. The thing is, prime number keep happening (at this stage in the game, very roughly every seventh number... (between the prie at 3001 and the one at 3203, the actual gaps are (2x)2, (5x)4, (3x)6, (2x)8, (2x)10, (4x)12, 14, 16, 20, and 26; so by another count the median gap is 8, but the two '10's gaps in that ~200 range happen to be either side of 3109 - make of that what you will).

Fun to work out, even if I'm just not sure that means anything. Not even the most obvious 'analysis'. Chief amongst the many numerical 'facts' is that (405 excepted, perhaps) every comic's number is exactly one higher than the one for the comic before. How totally amazing is that, eh..? :P 92.23.2.228 20:22, 12 July 2025 (UTC)
