Hey guys! Ever played Oxygen Not Included and struggled with keeping your base clean and your oxygen levels stable? One of the most effective solutions is using an iWater airlock. Let's dive into what it is, why it's awesome, and how you can build one yourself. Trust me, this will seriously level up your colony management game.

What is an iWater Airlock?

An iWater airlock in Oxygen Not Included is a clever contraption that uses a small amount of water to create a barrier between two areas with different atmospheric conditions. Primarily, it's used to prevent gases from mixing—think keeping polluted oxygen out of your base or preventing precious oxygen from escaping into the cold, harsh vacuum of space. This simple yet effective design relies on the principle that gases can't pass through liquids. So, by creating a small pool of water in a doorway, you form an impassable barrier for gases while still allowing your duplicants (your little colony workers) to pass through relatively unhindered.

The beauty of the iWater airlock lies in its simplicity and efficiency. Unlike mechanized airlocks, it doesn't require power, moving parts, or complex automation. This makes it an early-game viable solution that's incredibly easy to set up and maintain. All you need is a small amount of water, a bit of space, and a basic understanding of how gases and liquids interact in the game. For those just starting out, this can be a game-changer. Instead of scrambling to build complex filtration systems or dealing with contaminated air spreading through your base, you can quickly and easily create a reliable barrier that keeps your colony safe and breathable.

Moreover, the iWater airlock is incredibly versatile. You can use it anywhere you need to separate different atmospheric conditions. Common uses include entrances to your base, doorways leading to industrial areas that might produce polluted gases, or even as a buffer between your base and the outside environment. Some players even use them in more creative ways, like creating temporary clean rooms for delicate operations or isolating contaminated areas for decontamination. The possibilities are endless, and the more you experiment, the more uses you'll find for this handy little device.

Why Use an iWater Airlock?

Okay, so why should you bother with an iWater airlock? Well, the benefits are numerous and can significantly impact the health and efficiency of your colony. First and foremost, it maintains atmospheric control. Keeping your base oxygen-rich and free from pollutants is crucial for the survival of your duplicants. Polluted oxygen can cause sickness, stress, and decreased productivity. By using an iWater airlock, you create a reliable barrier that prevents these harmful gases from entering your living spaces.

Beyond just keeping out polluted air, the iWater airlock also helps conserve precious resources. Oxygen is a vital resource in Oxygen Not Included, and wasting it by allowing it to leak into space or other uninhabitable areas can quickly deplete your supplies. An iWater airlock ensures that your oxygen stays where it's needed, reducing the need for constant oxygen production and freeing up resources for other essential tasks. This is particularly important in the early game when resources are scarce and every little bit counts.

Another significant advantage is the low maintenance and ease of construction. Unlike other airlock designs that require power, moving parts, and complex automation, the iWater airlock is incredibly simple to build and maintain. All you need is a small amount of water and a basic understanding of how the game mechanics work. This makes it an ideal solution for early-game colonies when you don't have access to advanced technology or a lot of spare resources. Plus, because it doesn't require power, you don't have to worry about it failing during power outages or consuming valuable energy.

Furthermore, the iWater airlock can also help regulate temperature. While it's not its primary function, the water in the airlock can act as a thermal buffer, helping to stabilize the temperature between two areas. This can be particularly useful in biomes with extreme temperature variations, such as frozen or hot biomes. By creating a small buffer zone, you can help prevent drastic temperature changes from affecting your base and keep your duplicants comfortable.

How to Build an iWater Airlock

Alright, let's get to the fun part: building your own iWater airlock. Don't worry; it's super simple! Here’s a step-by-step guide:

1. Choose Your Location: Pick the doorway where you want to create the airlock. This could be the entrance to your base, a doorway leading to an industrial area, or any other location where you need to separate gases.
2. Dig a Small Pit: At the base of the doorway, dig out a small pit that's one tile wide and one or two tiles deep. The depth depends on how much water you want to use and how much of a barrier you want to create. A single tile deep is usually sufficient.
3. Add Water: Use a pitcher pump or a bottle emptier to add a small amount of water to the pit. The amount of water you need will depend on the size of the pit, but generally, a few kilograms of water is enough. You want the water to cover the bottom of the pit without overflowing.
4. Smooth the Edges: Use tiles to smooth out the edges of the pit, creating a clean and even surface. This will prevent any stray gases from escaping through gaps in the terrain.
5. Test Your Airlock: That's it! Your iWater airlock is now complete. Test it by opening the door and observing how the gases behave. You should see the water forming a barrier that prevents the gases from mixing.

Tips for Success:

• Use Clean Water: Make sure you're using clean water, as polluted water can off-gas and contaminate your base. If necessary, purify the water before adding it to the airlock.
• Monitor Water Levels: Keep an eye on the water levels in the airlock, as the water can evaporate over time. Replenish the water as needed to maintain the barrier.
• Consider Automation: While the iWater airlock doesn't require automation, you can add a liquid sensor to automatically refill the water if it drops below a certain level. This can help reduce maintenance and ensure that the airlock is always functioning properly.
• Be Mindful of Temperature: In cold environments, the water in the airlock can freeze, rendering it ineffective. If this happens, consider using insulated tiles to insulate the airlock or adding a heat source to keep the water from freezing.

Advanced iWater Airlock Techniques

Once you've mastered the basic iWater airlock, you can start experimenting with more advanced techniques to further improve its performance and efficiency. One popular technique is to use a double iWater airlock, which involves creating two separate water barriers with a small space in between. This provides an extra layer of protection and can be particularly useful in areas with high pressure differentials or extreme temperature variations.

Another advanced technique is to incorporate automation into your iWater airlock design. By using liquid sensors, pumps, and valves, you can create a self-regulating airlock that automatically replenishes the water supply and adjusts the water level based on environmental conditions. This can significantly reduce maintenance and ensure that the airlock is always functioning optimally.

Additionally, you can experiment with different types of liquids in your iWater airlock. While water is the most common choice, other liquids, such as oil or brine, can offer unique advantages in certain situations. For example, oil is less likely to evaporate than water, making it a good choice for long-term airlocks in dry environments. Brine has a lower freezing point than water, making it more suitable for cold environments.

Finally, consider the placement of your iWater airlocks. Strategically placing airlocks throughout your base can help create distinct zones with different atmospheric conditions, allowing you to optimize resource management and improve overall colony efficiency. For example, you might create a dedicated industrial zone with a higher concentration of carbon dioxide to boost the productivity of your carbon skimmers, while keeping your living areas oxygen-rich and comfortable.

Troubleshooting Common Issues

Even with the best-laid plans, things can sometimes go wrong. Here are a few common issues you might encounter with your iWater airlock and how to fix them:

• Water Evaporation: If the water in your airlock is constantly evaporating, try using insulated tiles to reduce heat transfer or adding a liquid sensor to automatically refill the water supply.
• Freezing: In cold environments, the water in your airlock can freeze, rendering it ineffective. Use insulated tiles to insulate the airlock or add a heat source to keep the water from freezing.
• Contamination: If the water in your airlock becomes contaminated, purify the water or replace it with clean water.
• Gas Leaks: If you're still experiencing gas leaks despite using an iWater airlock, double-check the edges of the pit to ensure they're properly sealed. You may need to add additional tiles or adjust the water level to create a more effective barrier.

By understanding these common issues and how to troubleshoot them, you can ensure that your iWater airlock remains a reliable and effective solution for maintaining atmospheric control in your Oxygen Not Included colony.
