## Questions about this video

What is the purpose of the cold loop in the TEG setup?

The cold loop circulates plasma gas cooled by space and radiators to create a temperature difference necessary for power generation in the TEG.

Why do gas pumps stop pumping at high pressure and how is this managed?

Gas pumps stop pumping when pressure reaches about 9,000 KPA. This is managed by installing an inlet pressure regulator set slightly below this limit to release excess pressure and maintain flow.

Why should plasma glass be replaced in the burn chamber?

Plasma glass can explode under high pressure caused by heating in the burn chamber. Replacing it with regular walls prevents explosions and improves safety.

00:01

Speaker A

Learning to make your first take can be one of the hardest parts about learning atmos in Space Station 14.

00:06

Speaker A

It seems overly complicated, and there aren't many good tutorials online. We're really just going to be going over how it works and how to build it.

00:17

Speaker A

So, it works through the conduction of different temperatures. You're going to have a hot loop and a cold loop.

00:26

Speaker A

And so, it'll take the difference between the two, and that's what makes the power.

00:32

Speaker A

So, we're really going to be starting with the cold loop. It's a lot simpler compared to the hot loop.

00:39

Speaker A

So, you're really going to be starting with a volumetric gas pump. These are necessary to keep gas flowing throughout the pipe. If you do not have a volumetric gas pump, the air will be stagnant because it will not be moving.

00:56

Speaker A

So, before you place it down, you're going to need to check which way the air current needs to flow. You can do this by shift-clicking on the circulator.

01:07

Speaker A

You can see the arrows here. So, I'm going to place the gas pump like this.

01:13

Speaker A

You can tell which way the air is going to flow because of the little arrow in front. So, it's going to be flowing down with the current.

01:21

Speaker A

So, to make a cold loop cold, you're really just going to be flowing it through space because space is cold. And you'll have the radiators, which are super handy.

01:35

Speaker A

You are going to build pipes and connect them down here. And so, your air is going to go like this through here, but we need to connect it back to the top of the circulator so that it can be

01:52

Speaker A

a loop. So, now we have a loop. But with our loop, you can see if you use your gas analyzer that has no gas in it. That is not good. We need a conductor gas flowing through the pipe

02:17

Speaker A

so that the temperature can flow through that gas. So, to do that, it's not too hard.

02:25

Speaker A

You are just going to replace one of your pipes, and you're going to replace it with a T pipe.

02:36

Speaker A

And then, you're going to take a—you can use a gas pump or a volumetric gas pump for this. It doesn't really matter too much.

02:47

Speaker A

And then, you're going to slap a connector port on it. To turn the cold loop on, you are going to take a plasma canister. Typically, there are a couple different gases that you can use for the cold loop, but the

03:03

Speaker A

best one that you're going to be starting with is going to be plasma. So, to get the gas going in here, you're going to anchor it down on the connector port. And then, go ahead and turn your volumetric gas pump on.

03:20

Speaker A

So, you can see it's blinking red. That's because there's no gas in there yet. To get it started, we're going to set our pressure to max, and then we're going to turn this on.

03:31

Speaker A

And then, once we turn it on, you can see that it's starting to flow in here, and so it's activated. You can check it with your gas analyzer to see that, too.

03:41

Speaker A

It's going to start getting cold as it circulates, and that's our cold loop done.

03:48

Speaker A

The hot loop is going to be just about the same as the cold loop, except instead of running it through space, we are going to be running it through a chamber filled with hot gas.

04:00

Speaker A

So, to get started on this, we're going to make another loop. We're going to need that volumetric gas pump. If you look on here, you can see that instead of flowing down like this one was, it's flowing up.

04:16

Speaker A

So, we are going to build another gas pump, and then we are going to put it into there. It doesn't really matter what side you put the gas pump on, in all honesty, as long as it's facing the right

04:29

Speaker A

direction. So, we're going to continue with our loop. And then there is one thing that we're going to add to this.

04:39

Speaker A

So, we are going to put a T junction on here like we did with this one.

04:47

Speaker A

But instead of doing just a connector port, we are going to build out a little bit.

04:57

Speaker A

And then we are going to go outside. And once we're outside, we're going to throw down a vent. So, this is basically just going to be a way to let a little bit of pressure out. So, when the hot

05:17

Speaker A

loop heats up and it flows through the burn chamber, the pressure goes up in the pipe because the heat makes the molecules move faster.

05:28

Speaker A

So, that would be a good thing because it makes the tank more effective. However, our gas pumps are going to be limiting us. So, gas pumps will stop pumping air once the pressure inside of a pipe reaches about 9,000. If we look in our

05:50

Speaker A

cold loop, we can see that the pressure is at around 1,800. That's perfectly fine. We're not stressed at all about that because the pump is working perfectly. If it was too hot in the hot loop and we didn't have a

06:09

Speaker A

release like we're going to make, it would completely stop, and the fan like this is moving, it would stop moving and it would no longer work at all.

06:18

Speaker A

So, to make our release for the pressure, we can craft an inlet pressure regulator. I like to use these a lot. I don't like to manually release gas. I do see a lot of people just make valves.

06:33

Speaker A

So, because our pumps will stop pumping at around 9,000, I like to leave a little leeway, and I will set the inlet regulator to 8,500.

06:47

Speaker A

That way we have about 500 KPA before the pumps will stop. So, we're going to set that, and now we can close that.

06:58

Speaker A

To finish our loop, we are going to actually make another T junction. And we're going to—you can guess—we're going to make another connector port.

07:14

Speaker A

Connect it up. And that way, just like our cold loop, we can have our gas flow in.

07:22

Speaker A

After that, we can continue up, and we're going to need to connect up to the burn chamber.

07:36

Speaker A

Make sure to leave a little extra room. That way your pipes don't overlap. It's not too big of a deal if they do, but I just think it looks a little bit neater.

07:51

Speaker A

So, now that we have the pipes in sort of a loop and going up to the burn chamber, we can head outside.

07:59

Speaker A

So, typically, there's going to be a button for blast doors. You can just unlock it like that.

08:08

Speaker A

And then, once you head outside, you are going to make radiators. I like to use inline radiators because they look cooler, and while the other radiators will work, these ones don't need pressure to work.

08:29

Speaker A

So, I'm going to put a couple radiators in here. So, with that, our hot loop is done.

08:39

Speaker A

Now, we can go ahead and put some gas in here to get this moving along.

08:46

Speaker A

So, I'm going to go ahead and anchor this down like we did before, turn on the pump, set it to max, that way all the air can go in here. If you don't set it to max, not all of the air will flow

08:58

Speaker A

out of the canister. Now, to get it moving like we have this one, we're going to turn on the gas pump again.

09:05

Speaker A

So, then now we have air flowing through here. And now our hot loop is done. On to the burn chamber.

09:16

Speaker A

A lot of stations will start with a burn chamber that has plasma glass for the windows. This isn't good because when air flows in and it burns, the pressure can get really high because it gets so hot. And in a recent update, they made

09:34

Speaker A

it so that glass can actually explode when the pressure is too high. So, to deal with this, we're just going to go ahead and I like to get a fire axe.

09:45

Speaker A

And now I'm just going to break this all down, and then we can move on.

10:02

Speaker A

So, now that our walls are cleared, we don't really have to worry about any of this junk. In all honesty, we can just build over it.

10:13

Speaker A

So, I'm just going to go ahead and place down the regular walls with my RCD.

10:20

Speaker A

This won't block any of the pipes or anything if you place it over. And it will work better than the glass because it won't explode, which is pretty handy.

10:34

Speaker A

And then, to make it a little bit easier to see in here while we work, I am going to put a light down.

10:42

Speaker A

So, in the burn chamber, we're going to need a few things. We're going to take our RPD.

10:47

Speaker A

And then, we are going to place down an injector. So, the injector is where we are going to hook up our gas to get it flowing in here. It pretty much just injects air.

11:02

Speaker A

And then, another component that we're going to need in our burn chamber is a way to let air out. So, when the air comes in and it burns, it creates a buildup of bad gas.

11:16

Speaker A

So, when the plasma burns, it turns into water vapor. And then, the oxygen will build up, and it won't burn as well.

11:25

Speaker A

So,

11:39

Speaker A

So, we can go ahead and open the door back up. I have these here so it doesn't space.

11:47

Speaker A

And like before, I'm going to use another regulator. You don't have to use one of these. I prefer to because it keeps the gas moving in one way and as well as stops it from getting too low.

12:02

Speaker A

So, it starts at 4,500 when you first build it. That's a fine one to keep it at as long as gas is flowing.

12:10

Speaker A

And then we're going to place another vent. Make sure to use passive vents. If you use air vents, they will not work.

12:19

Speaker A

So, now that our release is set up, we can go ahead and close these doors back up.

12:26

Speaker A

And then moving on to our gas mix next. So, a good mix of gas that's going to burn pretty consistently is going to consist of oxygen and plasma.

12:43

Speaker A

If you use just plasma, it won't be very effective just because the plasma burns doesn't mean that it's going to burn very consistently on its own.

12:53

Speaker A

So, up here we can see that there's already a setup going on that's going to be using our oxygen. It doesn't really matter too much if we take a little bit from it.

13:04

Speaker A

So, you can build another T junction. And then you can tell it's the oxygen coming from this because if you use your gas analyzer on the gas pump, you can see it says oxygen. I would always double-check before you fully turn

13:21

Speaker A

everything on because sometimes it's easy to mix up the wrong ports. So, to get the gas moving, I'm going to go ahead and turn it on. And then, always make sure to set the output pressure to max on the gas pumps coming

13:36

Speaker A

from the miners. If you don't, you may not have enough gas flow for everything that you have going on in Atmos.

13:45

Speaker A

To continue on, we're going to extend this down here. We need it to meet up with our plasma.

13:56

Speaker A

And then, like I showed you, we're going to double-check that this is the plasma.

14:00

Speaker A

Looks good. So, I'm going to take my RPD back out. Oops. And then, to make a good gas mix, you are going to need a gas mixer.

14:15

Speaker A

You can see the arrows on each side, and then it mixes the two and pumps it out.

14:23

Speaker A

So, I'm going to hook up the plasma gas pump, and then hook it up with our oxygen.

14:30

Speaker A

I'm going to turn on the plasma. And then, use my gas analyzer again to check.

14:40

Speaker A

And if you click on just the gas mixer, you could see the different inlets that it has. So, the north inlet is up. You can see it has the oxygen flowing in it.

14:51

Speaker A

The east inlet is east. You can see it has the plasma. So, when you go into here, you go are going to be able to set your gas mix.

15:03

Speaker A

I like to personally do a mix of 3% plasma and 97% oxygen. This burns really well and doesn't really use too much plasma.

15:15

Speaker A

So, the primary port is going to be the one coming straight on, and then the side port is the one from the side. So, if we want 3% plasma, we're going to set the primary port to three.

15:28

Speaker A

And then set it to max. I'm not going to turn it on just yet because I want to hook this up.

15:43

Speaker A

So, I think this is just about ready. We just need this one pipe. And now we can turn this on.

16:00

Speaker A

That looks good. I'm going to go ahead and put the final walls in here.

16:12

Speaker A

And take my holo fans back. And now if I go down here, we have both the gases flowing.

16:22

Speaker A

But we do need to start the heat because if you check in here, despite having the burn mix in there, it's still cold.

16:30

Speaker A

That's because we haven't lit it yet. So, to light my burn chambers, I don't like to use igniters or anything like that. They aren't very consistent and can take a minute to get started.

16:45

Speaker A

Uh the firefighter door remote is a pretty good way to open just one of them. That way all the gas doesn't flow out. You can use multiple holo fans, but this is pretty efficient for me.

16:57

Speaker A

And so, to get it started, I'll just turn on my welder and do a little circle in here.

17:05

Speaker A

And now that's started, we can head back inside. And then if you check here, we have the cold loop going.

17:19

Speaker A

We have the hot loop going. It's not quite warmed up yet. It's getting there.

17:26

Speaker A

It'll take just a second to really get flowing. So, it's not quite getting as hot as it needs to. This might be because I lit it too soon after the gas started flowing in.

17:42

Speaker A

So, you can see that it went out because the pressure wasn't high enough yet. So, I'm just going to light it one more time.

17:53

Speaker A

And that should be pretty good. It doesn't seem to be going out. Back inside one more time.

18:04

Speaker A

And then we can see it slowly rising. And there we go. Look, it's starting to get hot. So, if we look at the pressure here as it rises, you can see it's starting to get to that point past no

18:18

Speaker A

return. So, it's going to blink red for a second. That's because the pressure is too high, but our regulator pump is doing its thing. It's slowly pushing the air out.

18:29

Speaker A

And once it is stabilized, it's going to go back to flowing like this. And then we should be all set now. So, it looks hot. That's pretty hot.

18:43

Speaker A

Looks cold. And you can see how much your take is producing. If you look here, you can see how much it's capable of producing if you look here.

18:54

Speaker A

So, this take is able to make 3 MW. Um it's only making 230 kW because we don't need a full 2.6.

19:09

Speaker A

The typical station is going to need anywhere from 250 to maybe 300 kilowatts. You're never really going to need the full 2.6 megawatts.

19:23

Speaker A

Now that you have a fully set up take your station's power should be pretty good. You won't really need any other generators with this setup and it's pretty safe. If you have any questions, do feel free to ask in the comments.

19:36

Speaker A

I'll try to get to everyone that I can.
