I cant speak to other parts of the U.S. but where I am from, people would design their farm houses so that when you opened all the windows, the natural wind direction wanted to blow through your house and naturally "cool" it. Coming from a house with AC, it seemed like a shit system lol, but i guess compared to being roasted in your stuffy house, it was probably pretty nice

They actively use this design in large buildings (with a modern twist). Its known as a chilled water system: https://hvactrainingshop.com/how-a-chilled-water-system-works/
Or you have ones that do not run at all during the day, and only chill/freeze the water at night on excess power/cheap power: https://www.buildinggreen.com/news-article/making-ice-night-cool-buildings
The second system I linked would then let the ice slow melt over the day as its way of actively chilling air passing through its exchanger.
These systems work by chilling water instead of air, which has a much higher heat capacity. Meaning, it can accept much more thermal energy per unit mass before raising its temperature by 1 kelvin. You are able to build a single, very well designed, and efficient refridgeration unit that can provide HVAC services to up to multiple high rise buildings. This reduces waste and reduces the usage of coolant/refridgerant.
This system can be reversed in the winter (heating the water instead of chilling) with geothermal heat, solar heat, or if no "green" options are readily available, natural gas direct fire heat can be extremely efficient compared to electric coil
Not necessarily in your house. I'm talking about the design of the units from when you were a child (Many public buildings in the EU have AC regardless of houses not having it). AC was invented in 1901, and has come a very long way since then, and we have begun combining it with old principles to extract the best of both solutions
Combining modern refrigeration/cooling techniques with well designed passive systems that exploit material properties (Heat capacities, transfer coefficients, etc.) to their advantage is the future of HVAC. It started with CFCs and knowing we could exploit their boiling point with mechanical force to chill air beyond the outside air temperature. Who knows where science and engineering may take us next!
This would be a great idea if you want everyone in that building to file humidity complaints every single day. Air conditioners work by using mechanical work (compressor) to exploit evaporation in order to pull heat from one location to another and exhaust it away, in turn cooling the first location (this could be air, water, etc.)
This system works by using ground temp water as a heatsink to suck heat out of the air passing over it. When it does this, it humidifies the air. In the desert...who cares? In an office building...who cares? Every single worker who is stuck there all day
If you're saying we need better systems than the AC unit you grew up with, fear not! Many office buildings have been moving away from it (same with other large venues) they use a chilled water system. They use the best of both these systems to get WAY more performance out of way less wattage. You only need a fraction of the cooling power with a chilled water system because the water can absorb much more heat per unit mass than air and can be sized to never run during the day, but only at night when the grid is least in use
I wouldn't call it obnoxious, it's just pointing out that they are using terms that don't align with what they stated. If nobody ever mentioned the difference, how can they ever learn? Not saying everyone needs "taught" but it really didn't seem malicious like you seem to believe
The water does not perform work in this instance.
I do not think you're trying to say the water "does work" in the physics sense, but to clarify, the water is just a large heat sink that has a much higher heat capacity than air. You can heat the water with air (which in turn cools the air), and that water can hold MANY times the heat (per unit mass) that the air can. Water also has a higher thermal conductivity than air. Allowing it to absorb and pass heat very well. This water is in the ground which also acts as a massive heatsink.
The air passes heat to the water which then passes the heat to the ground effectively cooling your air feed. A quick look online says current soil temp in Iran 21 inches deep is 35C or 95 F. That is your lower temperature limit. It's physically impossible to become colder than the soil temperature (in this instance, as that is your lower temperature bound for heat transfer, in reality you wont even get there, because your driving force for heat flow is gone at that point) without putting in mechanical work (which is what a compressor does in your air conditioner) to compress your cooling fluid so that it may be evaporated repeatedly to exploit the tranfer of heat into an evaporating substance
Having played Factorio, Satisfactory, DSP, and Captain of Industry. I personally find Satisfactory to be the least enjoyable of the group. I have the hardest time playing it all the way through (its pacing falls apart in phase 4, I expect this to be fixed as they complete more of the game). If you love factorio for the logistics problems and factory expansion, you may find Satisfactory long term tedious and grindy. The BP system is still in its infancy (they are pretty small BPs, you need mods to use larger ones, and you can't use mods in Multiplayer on a server if you intend to play with friends).
The first person aspect is super cool, and it's "base building" is rivaled only by minecraft in the sense of you can build full buildings in your factory. Those only had so much shine for me before the tedium of lining up belts perfectly, running train lines without them doing weird bending and shit, and the slow process of hand building full setups without the ability to quickly place items one after another or rapidly run/readjust belts.
This is entirely a personal opinion, and I like Satisfactory as a game. I feel it has a lot of potential down the line, its just not able to keep my long term attention (nor anyone I play with) compared to the other factory games I listed. I have played through DSP and Factorio multiple times through, I've played Satisfactory 3 times through and have always quit in phase 4 at different points as it becomes a literal chore to me to set up these huge (at ratio) processing lines when I don't have any form of top down building. It makes me wanna do a DSP or Factorio run instead (possibly Captain of Industry, but I have the least experience with it so far so I cant speak much on it)
Also, many developed countries tout EVs as "AMAZING" for the environment. Meanwhile that is solely because none of the lithium mining and processing occurs in their nice countries. While they get their nice "green" batteries, China and South American countries destroy their environment strip mining and processing lithium ore. That shit is TERRIBLE for the environment, and there is no economic incentive to clean up the process. The news, media, politicians, CEOs, etc. never speak about this because it paints the reality of the picture. You're shifting the carbon footprint to something else, not really even reducing it.
I actually am very interested in the new solid state batteries Toyota is talking about. Using polymer based batteries can allow for longer lasting, less impactful energy storage to help make electric/H-fuel cell cars genuinely green/a great step from combustion vehicles
They have announced and have been working on a DLC expansion for the game
My girlfriend and I dipped out after MANY months of BTB being completely non functional. The 4 player Playlist got stale as all fuck (due to having like 3 game modes, not even infection until this sesson) and we just haven't been back since. We play MCC now and again, but infinite really screwed the pooch on this one.
I'm not opposed to ever booting it up again, it's just gonna have a very hard time competing for our time
That is the deepest depth I could find being actively tracked on the website I ended up on. I did not wanna do a deep dive into "great" average soil temp data lol. If you have a good source of data I will gladly change my comment to include the updated numbers. I wanted to say the average soil temperature at depth is ~50-55 degrees F, but I hopped online to make sure that was not a number that I know to be true due to where I live. Good to know that its roughly 6 feet where it stabilizes
