    • It will take time for the temp to decline, but you are also fighting the heat of the crop itself which starts at 19c at every planting and it has 400kg of mass. Having hydrogen directly in the room makes this a little tougher because it is the gas most readily going to exchange energy with the plants and warm up. The temperature of the plant doesn't matter in terms of getting ideal temp, just the temp of the gas around it.  A more insulating gas would work.

      Insulated pipes not made of abyssalite are also not that great compared to just regular pipes/tiles of abyssalite.
    • In terms of things you can construct, only abyssalite tiles really block temperature transfer.  The airlock doors of all varieties are metal and extremely heat conductive. The water in the water lock takes up the temperature as anything else does.
    • This depends on what you're trying to cool. For example if you're trying to create an environment for mealwood, then the mealwood itself helps stabilize it around it's ideal and your primary goal is proper insulation with abyssalite tiles and making sure it has good air pressure. If you are looking for something more direct you have basically 3 options in combination of good insulation. Radiators, Piping in cold gas, and wheezeworts.

      With Radiators you can use liquids or gasses.  There are no devices that directly cool liquids so their application can require some luck regarding having liquids of  the right temperature in abundance. (Though there are exploits that let you sort of cheat this process to create indefinite liquid cooling). For gasses you have the option of using Thermo regulators that remove heat from processed gasses piped to them and take that heat energy onto themselves. This means that the regulators will probably need to be cooled in some fashion as well. In either case you will pipe you liquid or gas around with a conductive material like granite creating a loop that covers as much area as possible.

      You can also just pump the warm air out of the room you want to cool, send it through a regular and then pipe it back in to condition the air directly.

      Wheezeworts are energy free plants that you can put in planters that will chill air around them. They're more effective if they process a gas like hydrogen so sometimes these are used in conjunction with regulators where you put the thermo regulator in a hydrogen filled room with wheezeworts and pump cooled hydrogen around in a radiator.

      If you're more specific about what you want to do people can probably offer you more specific advice.  The community seems pretty helpful.
    • My intention was not to demean your accomplishment regarding your steamer/heat exchanger. I am sympathetic to the goal of energy symmetry that appeared to drive your design ideas. And I definitely learned some things to take away from that thread that will probably be useful in ONI projects going forward. But strictly speaking if we're going to talk about exploits, as alluded to above using the tepidizer, it was probably not intended for such use and is probably in the realm you carved out for exploit. The the unique tendency of ONI fluids resulting in the scheme of mechanical separation might also fall under this category. But it is not wrong to say you work with the tools you have if you consider them in the spirit of the game.

      Considering how water geysers exist in relative abundance and that I very much doubt they are intended as a trick to get people to cook their base without alternative, I am going to say going forward their use is intended and that using that inexhaustible source of water is probably going to remain.

      Though, outside early game microbe mushers and later Co2 Air scrubbers, clean water is a luxury and not a necessity. It is probably possible to survive (if in a stressed situation) without nearly indefinitely if you have a solution for the the Co2 (void tile and less indefinitely through freezing). If I start a new colony I might just give it a try and see if I can manage completely independent of clean water either through natural sources or filtration/purification after cycle 80.
