Adapting my previous designs for the rge and small cryocoolers to be made in the irling facility took eighteen days. Then, while I had the goblins making the cryocoolers and stirling eo power them, I started building the new facility. I started with the underground part of the facility, si would also provide me with the stoo build the above ground portion of the facility. I decided that ultimately, I want a five foot thick roof on the underground portion, along with a few small vents to let extra air out from any evaporating materials.

  After taking nearly thirty days, I'd excavated the underground portion and had finished work on the dewar style tanks for st the cryogenic fluids. Each tank is equipped with two outlet valves, a pressure relief valve, a small cryocooler to keep the tents liquefied and an emergency failure patch of thinner material that should fail before the rest of the tank. The underground room also vents to atmosphere in case of an actal spill or a more catastrophic failure.

  The first tank was a ten foot in diameter by twenty feet long monster of a tank that I embedded partially in one wall. If the atmosphere is something like 75% nitrogen, then this tank should take about four years to fill up with liquid nitrogen. The sed tank was eight feet in diameter and te long. Using the same heuristic pattern, this one should hold about four years worth of liquid oxygen. The third tank was four feet tall and three feet in diameter, and should hold four years on.

  I also installed two more tanks that were identical in size to the argon tank. One is for holding liquid air before it goes into distiltion, and the other is for holding the argon rich oxygen portions until they go into a separate distiltion n. I haven't started on the , but I've decided on making two fifty gallon ns, and two ten gallon ns. The rger ns are for separating liquid air, while the smaller ones are for processing the argon. Since we're doing batches, I want to have two ns for each, so that we would have redundancy during mainteimes.

  Unfortunately, designing the ns actually requires that we have access to liquefied air so that I do the necessary tests to determine n effibsp; However, I did learn quite a bit from the st n design, so I could get most of the ns' pos built before I actually started fiuning. All in all, after twenty-four days I'd finished getting the ns mostly assembled and the casting teams had made all the rge cryocoolers. Well, they'd made the shells. I still o take the time to charge them with hydrogen.

  So, , using the stone from excavating the underground portion, I first rebuilt the roof over top the pit where I'd been w, to make a basement. I then installed some of our fluorite crystal lights on the ceiling in the basement to keep things visible. Then, over the course of awenty-six days I had the surface building built. Once again, I went with a double yered desig to help keep the inside of the building more insuted. Ultimately, I desig to be a long hallway with fifteen cryocoolers oher side. Their hot eend out of the hallway and are exposed straight to air for now.

  At the other facility, they have flowing water to cool their hot end's down enough to allenic temperatures. Here, I've goh a slightly different approach, and we'll see if it will work. The hot ends have very rge copper heatsinks installed on them with a fan blowing air rapidly over eadividual heatsink's surfabsp; The fans are angled upwards toward the sky to hopefully direct the heat up and away from any air intake. The issue with attempting this before would have been the amount of meical power necessary to actually power an active cooling system in addition to the cryocoolers. Now, with the fluorite powered stirling engines, I'm less ed with not having enough power.

  I've gohrough a lot of trouble to attempt to design this pce to ehat the air is into the cryogenic building are isoted from all the rejected heat that we're produg. Along the roof of the facility is where the five rgest stirling engines will sit to power the cryocoolers. At the far end of the building, there will sit two more engines of the sed rgest size, each driving the fans for the heat sinks on their respective side of the building. The air intakes into the building gh desit, and then their own moderately sized freezer chamber desigo freeze any remaining water, and potentially some of the CO2, out of the air before it reaches the main room. Each of those freezer chambers also has it's own stirling engine power source, though it's being meically powered through a long axle to keep the engine further away from the air is.

  Ultimately, it's very simir to the other cryogenics facility, however, due to the size of it, many items were scaled up. I have about twenty days worth of ges and adjustments to make before I actually start turning things on by fetg the crystal ptes to plug in to the bottoms of the main stirling engines.

  The first thing I o do was gee enough hydrogen to charge the cryocoolers. The hydrogen facility seemed to work, at least for the time being. I didn't hat much hydrogeher, so perhaps iure if it runs for a very long period of time, it might end up showing signs that I o make ges. Ultimately, I brought the hydrogen geing ptes up from ste down in the crystal facility for a few days to make the hydrogen I hen put them back down there. If the hydrogen pnt starts running full time iure, I'll want to keep an eye on it for a bit to see if I notiy dangerous defects .

  After the cryocoolers were charged, I went through a manual check of all the es and devices to make sure that nothing was experieng any sort of meical issues that would potentially cause meical failures that would require rebuilding things. Once everything seemed to be good, I was two days ahead of my estimate, and so I tried to turn the facility on by installing the fluorite heat crystals.

  At first, everything seemed to be w as I expected, which had me feeling quite good. However, as I brought more crystals up, and started turning on more of the cryocoolers, I started to noti issue. With eaew power stirling eurned on by bringing up a new crystal, the more all of them seemed tle. By the time the st engine was turned on, I could tell that they were all struggling to actually power the number of devices they were attached to.

  If I hadn't already desighe air system going down to the crystal growing area, I'd probably be more stumped on what was happening. Today, however, there is almost no wind, and while I know that mana flow against the dire of airflow, I know that it more readily flows with the dire of airflow. We've got a total of six massive stirling engines powered by est crystal ptes, and four of the rgest size, all trated within this one area.

  So, I did a small test, and sure enough, my mana regen on the roof of the building was about half of that just over fifty feet away where it was normal. So, first I shut down all the engines so that they wouldn't degrade, and moved their heat crystals baderground to preserve them. Then, I got to work on what I hoped would be a w solution.

  If mana flow is helped by airflow, then it's somewhat reasohat we just need a bigger natural airflow over these engines. On a windy day, they might run fine on their own, but I don't want to wait for a windy day. So instead, oher end of the roof of the long, hallway like building, I installed two massive fans pointed from the front to the babsp; Each fan has a ten foot radius with six bdes, and it rotates about 10 times per sed.

  Building them took six additional days of time, and I used a single of the sed rgest stirling eo power both of them. There was a signifit amount of airflow over the roof now. I then took a day getting all the stirling eurned ba. This time, only the very st engine seemed to be struggling a small amount to keep up, while the first engine was actually w overtime.

  I could already envision a much better system, using individualized air ihat would flow directly over closed cavities over top the crystals for each stirling engine, but implementing them would take additional weeks of time. Instead, I took ara two days, and installed two smaller fans angled in on that side of the building poi the st engine, and that seemed to do the trick.

  Thankfully, it's the middle of winter now, meaning I easily go and move the goblins who worked at the old facility, and bring them to work at this one. I'll need more intermediate dewar fsks for transp and colleg all the cryogenic fluid we'll be making while I fiuhe new distiltion ns. So for now, I'll shut the facility down again for a few days while I get the goblins up to speed.
