Swamp Coolers are a more efficient replacement for Air Conditioning where I grew up in Utah. The air there was so dry normally that you would need to add humidity to it in order for it to even feel normal. Plus the incredibly hard water we had actually made the cooler more efficient by constantly leaving calcium deposits on the thatch it used as an evaporation medium. As they built up, the little calcium crystals would increase the surface area being presented to the air. Eventually, after a few years it would get too clogged and we'd have to replace it with a new panel but as long as you had a trickle of water and enough power to run a barrel fan, you had something that would turn your lips blue if you stood underneath the vent for more than a minute. You put that vent in a central upstairs room and the cold air coming out naturally sinks down through each room until it pools down in the basement. That's just how nearly everyone cooled their homes off where I grew up.

[@rite2bcreative]

I live in Utah and this was definitely my experience too :) Lots of memories laying on the top floor landing with my sister after coming in from outside and feeling that ice cold air hit us! Also lots of memories changing out those panels every few years, replacing the pump every great once in awhile, and of course draining the water and taking the cover on and off. They really are pretty simple to take care of and cheap. It's too bad they don't work well in more places

[@Jumpboots_Jamstrang]

Ibra Chaka Scam is a good word for it, calling this an “air conditioner” is baloney. At it’s core, the theory behind refrigeration/air conditioning is to take the heat from an area where you don’t want it, and spit it out some place where it doesn’t matter. Swamp coolers are not capable of that whatsoever, and will only work where it’s warm and dry. They would be fantastic in Arizona due to it’s desert climate, less so in Florida because it’s so humid already. In that setting, it’s essentially a little desk fan, and will not do much for you.

[@vergeofapathy]

There's an even more absurd issue with these: Somewhere around 60% relative humidity, slight increases in air humidity lead to significantly increased apparent temperatures, due to massively lessened effectiveness of perspiration. So if you use them for long enough, these things will end up making you feel hotter, not colder.

[@JohnnoNonno]

Yeah, if you live in a humid place you experience this almost every summer: here in Milan it never goes over 35 degrees, but since it's *VERY* humid it feels much much hotter. So much so that there's literally a word in italian (afa) that means "hot and wet weather".

[@kelaEQ2]

Basically, if you don't live in an area that averages around 35% relative humidity these things are useless. However, if you do they can be a god send. I used to live near Sacramento, CA and depending on which way the wind is blowing, these things work great. You see Sacramento there are 3 different ways the Air Blows, from the North the air temp is the hottest, not blowing at all when it feels the hottest, and from the South West, when the state's Natural and quite literal Swamp Cooler is active, known there as the Delta Breeze, as it is when the Wind blows over the Sacramento River Delta prior to reaching Sacramento. Swamp Coolers are so effective during certain times of the year in Sacramento they have gigantic ones on the tops of some buildings there, like 10ft or more tall. I had one that was a "room" cooler, and it actually cooled the house ~2200 sqft for most of the Max heat days of the summer, when humidity and temperature was at Arizona levels, in fact at that level of humidity you may actually WANT to add some water to the air to make the AC more Pleasant as it will squeeze what little water there is in the air out of it.

My guess (also not an engineer) might be concerns that the condensate will not be purely distilled water, but distilled water from the humidity in the air *plus* whatever pollutants might be in the air that might come along for the ride and change the pH of the water. Possibly enough to be corrosive over time. Mind you, I’m mostly speculating as to the source/ rationale for the concerns of concerned. I am old enough to remember hearing talk of “acid rain”, but not quite old enough to remember what exactly it was (if it was different than what I described above). The validity of this concern would also likely vary by location, presumably greater in large metropolitan areas (especially in countries with low environmental standards), and lesser in rural areas far from any industrialization.

Well, corrosion is a thing, too. And yes, it will degrade the process to some minor extent, but it's hardly enough to make a difference. Yes, the condensate "water" will be some nasty stuff, because the air it came out of was rather nasty, and it ran off nasty, dusty, dirty, corroding mystery-metal (and copper.) (note: the condensate lines from our data center chillers are silicone, and copper. and despite the relative quality of the air, that water is not clean either.)

[@BobWiersema]

It also serves to evaporate the condensate water. That's very useful if you use them in a inside office space like I do. No water dumping on the floor outside.

[@YTubechangeAccount]

Its also that they use a material that is more corrosion resistant (chromium, manganese ect mixed) because it will be exposed to more than a light condensation. The same amount of water exposure may shorted the life of units not built to have water sitting inside it as part of its design, as it would use slightly cheaper composite metals (other than the aluminum fins, which weigh+cost less than copper fins with not much less heat transfer & more corrosion resistance) These reasons are better explained in next years video he makes, the magic of metallurgy, & not including it here was to make this a better video (reasons why he so good!)

[@saltherilshaven]

I just realized why it's harder to get cool in a humid environment. As he said in the video, if the atmosphere can't take on any more moisture because it's too humid, then your body can't use evaporative cooling (sweating) to cool down. It makes sense now! Thank you for educating me!

[@jonathanberry9502]

Actually, you can break second law of Thermodynamics! You see Joule screwed up, according him the energy released as heat from compression is about equal to the energy put in to compress the gas, but he ignores the fact that the gas cam be re-expanded and this can power about 80% of the energy needed to run the compressor in the first place. If you cool the compressed gas to ambient it still has most of the energy that you invested in compressing it remaining (it loses about 2%. If the compressed gas is allowed to come to ambient temperature, you can then decompress it and make it super cold, so now you can extract about 70% at best of the energy from the thermal imbalance created. The device can output usable mechanical/electrical energy and provide cooling. The second law of Thermodynamics doesn't work where pressure changes occur because most of the energy invested into compressing a gas is regained on decompression, but current technology (heat pumps, aircon, freezer) doesn't try and gain energy from decompression, they throw that energy away.

Indeed they are. Ancient civilizations in the middle east used to build towers that functioned the same way. They were meant for travelers and rulers who desired cooling areas.

[@cleonituk]

Which makes me wonder why stores would bother carrying them in obviously very humid states.

[@donbionicle]

@@cleonituk Because as demonstrated in the video they are dirt cheap to make. Consequently only a few suckers need to buy them to turn a profit, even if the rest of the stock sits unsold!

[@Choralone422]

@@cleonituk stores in humid environments only carry these "air conditioners" because the margins on them are high since they're usually overpriced. You would be surprised at the number of dumb people who see a real window A/C unit for $150+ in a store and think they're getting a deal with one of these personal "air conditioners" for $40-80. Those are the people the stores that do carry them are counting on! Most of the marketing for units like in this video is being done via the internet in ads on social media, in-game ads on mobile games and various websites, especially news websites. Again counting on people thinking they're getting some sort of deal cause it costs less than a real A/C unit but it's not super cheap so it must have something substantial inside right? LOL

[@KuraIthys]

@@Choralone422 I wish I had ever seen an actual AC that cheap. Around here (granted not US currency, but it's the relationship that counts) An evaporative cooler will go from about $40 to $150 depending on size and construction. The cheapest air conditioner I have ever seen for sale is $550, which is more nearly 14 times the price of the cheapest units, and still more than 3 times the price of the most expensive. Then again the whole category of window mounted AC largely doesn't exist in this country (it used to, but I haven't seen one on a building or for sale anywhere in about 20+ years) So you go straight from the somewhat questionable portable AC in the $550 to $1000 range, to split systems which start at about $1500 (not including installation costs), and can easily get into the $5000+ range, if not substantially more... So, yeah. AC is not that affordable around here. Especially if you're in rental accomodation, because the rights of landlords to restrict what tenants do to a property are very extreme, and make it hard to do anything at all if you're renting...

[@Chiaros]

Your explanations are great

[@damaliamarsi2006]

I had a friend who lived in Mojave CA who had a swamp cooler and would turn it on for the summer months and it kept the house cool. Basically a four sided box with wet paper on the sides and pan that gets water from a copper tube that is metered by a toilet float mechanism. Super cheap to run and fix. Kept the humidity at around 55 to 60% in the desert which is not bad.

I just watched a 30 mins video explaining how something I've never seen or would have ever bought doesn't work.

Mine works great.

[@silver3882]

My parents bought me one cuz I needed a fan.. that thing made my room hotter it was a waste of 30 dollars and we returned it and got my self a normal fan

[@tzukishiro]

Except it works amazingly well

[@shakesbits5220]

Except that whether it works depends on where you are - where I am and for my purposes it works and it was only 20 bucks or so.

So fun fact: the medieval reenactment group The Society for Creative Anachronism used to use Freon cans as helmets. I've seen some of them: they really weren't actually strong enough for the purpose (and have now been phased out, though some groups keep them on hand as "relics."

You should cover car ACs too. 10/10 on this. Very informative and funny 😂

[@Gremlack13]

I lived in the high desert of Wyoming for 11 years, using a swamp cooler. It’s amazing how cold it can be and how well it works. Can cool a home with a 3/4 hp fan motor, and a small water pump. It also puts moisture into the incredibly dry air of a desert. They don’t work well in a humid environment.

[@laurajphillips5981]

Gremlack13 Plus put in ice cold water it also work great !

[@ukeleleEric]

The only problem is: swamp coolers use up water. And water is scarce in the desert, so then has to be pumped in from elsewhere, so the cumulative effect on the environment is greater. I'm just glad I live in the UK. No AC needed, few fans occasionally at height of summer (some years).

[@GaetanoRomano]

And a shitty weather all year around causing one of highest depression rates in whole Europe over the winter. At least is environmental friendly!

[@robertwoodliff2536]

G13....,you are in the right place....,it must help a lot to get some moisture in the air & if you can get solar panels to provide the power you would have cut out another cost.

[@RangerM98]

@@ukeleleEric True, the accumulative effect on a LIMITED reservoir of water (sending the water out into the environment rather than to be used by drinking) could be a consideration (3-15 gallons/hour depending on how much cooling you need). But too, you can always look at the glass half full by realizing that a swamp cooler costs 15 cents a Kilowatthour (KWh) of electricity, where as an AC Unit would be costing about $1.20 a KWh for the same cooling. Therefore (for instance and assuming the electricity is made from a 'coal-fired' electricity power plant), all the coal that is burned to create that extra electricity needed (in the case of electricity powering AC systems) creates that much more CO2 to put into the atmosphere (greenhouse gas), to contribute to global warming. To suggest that a swamp cooler is less environmentally friendly than an AC System is very debatable.
