  1. You're better off using abyssalite tiles and putting your pipes on the tile right above them. That way the exchange will be directly between the water and the pipe, it won't need to go through additional layer of granite.
  2. If you mean heating water in liquid pipes by water in other liquid pipes or by gas in gas pipes then probably yes. But since that puts two pipes in the way besides the granite, it's going to be very slow and inefficient. The fewer mediators between the heating and heated element the better.
  3. Technically you can create any kind of carbon from CO2. It's literally nothing but carbon and oxygen so once you get them apart you can make anything with them. The only problem is that they're very happy together. Getting them apart costs all the energy that was before acquired by putting them together. And any sort of catalyst or inventive design cannot get over that since that's law of conservation.
  4. Since you're essentially moving the heat from one water body to another, putting them right side by side is definitely the best approach as there's no mediator slowing the heat transfer down. In general, though, either type of water has worse thermal conductivity than granite. Water: 0.609 W/m/K, Polluted water: 0.58 W/m/K, granite: 3.39 W/m/K. So using water filled mesh tile to conduct heat from e.g. one gas on one side to other gas on the other side is worse than using granite tiles. I'm however not very sure about what exact formulas does the game use when calculating heat transfer. The measure of distance in these constants has no clear sense in context of ONI.
  5. You cannot separate polluted water and clean water pools with a mesh tile filled with either type of water. If you can prevent the two waters to mix, you don't have to use the mesh tile, just put water on water.
  6. One more comment to your design: mesh and gas permeable tiles don't conduct heat between neighboring tiles. They're only in contact with the "ambient medium" in them, i.e. the gas or liquid. A gas permeable tile containing vacuum is perfect heat insulator, better than abyssalite. The heat transfer between polluted water and the cooled water in your design is going only through the bridges and whatever gas is left there in the permeable tiles, the material of the tile only acts as thermal mass again. Here's a small experiment I ran, there's vacuum in that permeable tile and the temperatures of water on the left and right didn't change at all. Below is a granite tile separating the two waters and it has already transferred measurable heat between the two. Water on the left had 6.9 C and water on the right had 96.9 C initially. Granite has greater conductivity than any gas you may fill your permeable tile with, so granite tiles are your best choice. Edit: I compared granite tile to gas permeable containing 2 kg of hydrogen and the granite tile won.
  7. Thermal mass has only effect while the temperature is changing. After some time running the machine, things will have constant temperature at each point and the thermal mass will have no effect. Okay, I neglected that. You may be right about it, there doesn't have to be an exploit in your cooler. Though the first stage of cooling then depends a lot on temperature of the polluted water you send in. I'm a bit confused by your pipe radiator though, you seem to be sending already heated water back at the end of first cooling stage where the water is already relatively cold and should be colder than the water in the radiator.
  8. No. The effect just limits the amount of heat that can be transferred per second. It does not affect heat contents or thermal inertia of the medium you use. If you send 1 g packet of hydrogen to the pipe, it will exchange all its heat in first pipe segment and then it will be useless.
  9. Regarding heat conduction along wires/pipes: test chamber with vacuum in debug mode. There was no transfer at all. Wire and liquid pipe is wolframite, gas pipe is granite.
  10. Well the tepidizer on its own is an exploit, and 2400 kg/cycle of water at 30 C from steam requires 1.17 MW of heat removed continuously. That would be almost 38 kW per wheezewort, and that's more than twice their best performance in hydrogen - so I assume cooling runs on some kind of exploit too, even if unintentionally. And if we're ok with using exploits, then it can be made much smaller. Also, the wires in your design do nothing. There's no heat conducted along wires or pipes, except heat carried by contents or surrounding gases/liquids/solids. The wire/pipe bridges do help, though, as they are in contact with environment in all three tiles they cover.
  11. I think the complaint about valves not using power was based on the fact that you can propel liquid or gas in pipes in closed cycle without pumps or filters in the way. It's not fault of valves, though. You can "propel" the contents in pipes using bridges too. Or just by putting a filter output on one end and filter input on the other end, without powering them up. It's because in ONI, the pipe itself propels its contents, and you only pay power to do something with it, such as place it in the pipe, sort some element out, or process it to something else. Powered valve is not realistic but would make sense in that already unrealistic context. Except I'm pretty sure people would complain about powered bridges, so that would have to be implemented differently, by adding a genuine pipe crossing without adding inputs or outputs. That would be a lot of work, it would break a lot of current designs and I believe there's not much point doing that.
  12. Pipes in ONI don't work like real ones. They always send their contents from an output (green) to an input (white). If they have both behind either end, they get confused. It's always better to first "collect" all outputs, and only then route it all to inputs. It's also possible to add bridges or valves to force direction on such "confused" piece of pipe.
  13. Over sufficiently long time, your base is either creating more polluted water than it can use, or less of it. If you make the buffer large enough, this trend will rule the use and either the pump will run time to time, or the vent will be used time to time. You don't need or want your lavatories or showers out of order.
  14. You don't need to run anything to keep mealwood at ideal temperature. Make the farm as small as possible, just enough room for your plants, no wires, no pipes, all enclosed in insulated or abyssalite tiles. Best if you have inert gas in there, hydrogen or CO2. Ideal temperature for mealwood is 18 to 22 C. A plant - any plant - when planted is at 20 C temperature. 400 kg of biomass at almost exactly 20 C, right in the middle of the ideal temperature range for mealwood. Even if the room isn't at ideal temperature right at the start, the mealwood will condition it to that temperature itself, given enough time.
  15. If I understand you right, you can achieve satisfactrory functionality with this setup: Polluted water from your base is coming from the right in the bottom pipe. The bridge acts as a priority joint, sending the incoming water through the bridge if possible, and only letting it continue through the pipe if the bridge is blocked. Behind the bridge, there's a pipe buffer. It's there so that there's a reserve to be processed before the pump is used. The bridge from the pump will only start adding water towards the purifier and using power to run the pump if even the buffer gets empty. The water from the base will only start flowing to the vent if the buffer gets full. The only way to use your pipes from lavatories/showers as a buffer is when you make the branch towards the vent right behind the showers/lavatories. It's not very practical as you need to draw more pipes through the base. It's better to keep pipes in your base empty and ready to use and have sufficiently large pipe buffer at some convenient place.
