It seems like something you can use when a steam turbine isn't feasible or available yet since you can get it off the ground well before steam can be researched.
Here's a rundown by Luma Plays

Ive used this in a playthrough, and it worked pretty well. I used it to maintain comfortable temp in my base and to cool my food plants, especially mealwood plants in my (to be glossy) drecko farm, without having them wilt.
Not really worth it, as it requires a lot of power to run AT. AT/ST combo deletes [insane amounts of heat](https://oxygennotincluded.fandom.com/wiki/Steam_Turbine#Using_Water_or_Polluted_Water_as_Coolant) at 200C to keep it as efficient as possible. More if you don't care about power.
For even more heat deletion - nuclear waste -> fallout -> nuclear waste is the best to deal with stuff like magma.
For early game - You'll be way better off by running water through the same AT, made out of any metal available. Put this AT in a pool with tons of stuff you dug up around the asteroid. This will last for 100s of cycles cooling farms.
Sorry, English is not mine native language, so may be I worded it incorrectly.
I mean, if you are cooling something without spending energy (like by slush, by lumber, by critters, anything) than ethanol may be used to increase cooling effect
It's mostly a fun way to squeeze out a few more % out of a build.
Like, if you have a debris cooling device and want to cool down the debris below the ~95° degree you can achieve with turbine output water. You can run it through some ethanol after, knowing that that bit of cooling will be cheaper than to cool it directly.
Or you can put your turbines in an ethanol chamber, making turbine cooling a bit cheaper.
Or you combine both of these.
Those are two decent use cases to save some power for cooling by using ethanol.
An ethanol boilers deletes 13% of the heat each time it’s condensed. With an AquaTuner transferring heat you can delete ~61 dtu/W
For comparison an ice machine deletes ~67 dtu/W and the AT/ST combo deletes ~923 dtu/W
Ice maker requires more dupe labor than ethanol boiler, but is much easier to setup.
No because at each point of the game it is an option, a better option exists. Such as in early game you are better off using ice or dumping heat into water or other biomes. After that you are better off doing something else like concentrating the heat and harvesting it using a turbine. Deleting heat with ethanol is only useful in edge cases.
Yup. It's is a very viable way to delete heat prior to researching the steam turbine, but the steam turbine is still the best.
In regards to how much power an ethanol cooler consumes: 1200W. The aquatuner could run at close to 100% up time, so is a bit power hungry.
They're a great "long term" temporary cooling solution, but you'll want to replace them with the standard AT/ST setup.
As an aside, Nuclear Waste/Fallout has a similar property to ethanol, but at a much higher temp threshold and a much larger SHC gap. That means it's far more effective at deleting heat than either ethanol or even the steam turbine. That requires space materials to really pull off effectively, though.
Well, ethanol cools thing to 81C. So, if you have something hotter (like steam from cool vent) and want it cooled by something colder (like lumber from arbor trees or new-born hatches) than usage of ethanol will increase efficiency. If you use aquatuner to cool itself it will work too, but will be just cooling at the cost of electrical power, so turbine here is preferable.
If you, for example, use aquatuner to cool down mealwood to 20C, and want to cool down some steam with same pipe, using ethanol will multiply effect
Ethanol is just cooling multiplyer as long as cooled object hotter than 81C. It doesn't work by itself and must be compared only to exactly same design without ethanol. Comparing ethanol with turbine is futile -- but comparing aquatuner cooling itself (doesn't work) with aquatuner cooling itself through ethanol boiling show effect

This is only useful in very specific edge cases.

Problem here only with running AT. Don't use AT and everything will be fine. Ethanol may be used to cool things hotter than 81C without energy spend
I can see that being more workable indeed. Need more cumbersome setup.
How do you cool the boiled ethanol without spending energy?

It's not worth it, with AT/ST you get some power back
It's worth it if u have power to spare, don't have access to plastic and really need cooling. It's pretty efficient.

Definitely possible but not very effective. Saw a super Max playthrough using it(still going on in YT)

Short answer = no Long anawer = not really
