Reading over the dev diaries and some of the streams I have a few questions. Some of the disasters and problems seem to me to lack the proper tools to combat them. I'm very much interested what you think, if I am forgetting something.
- Sandstorms shut down your oxygen production, but I don't understand why. While external intakes for CO2 may need to be closed to prevent damage, nothing should interfere with splitting CO2 removed from the atmosphere of your domes. Of course, lack of power may cause oxygen problems indirectly, but the machine should itself should be fine working during a sandstorm
- Water seems to be a open system as well, without any recycling by default. There was talk about a water reclaimer, but as a spire, instead of very basic equipment for every dome. In fact, I'd be very worried about not removing water, as high humidity can cause mold and all kinds of electrical problems.
- I am also very much confused by the subsurface heating for surviving cold waves. Why should it be preferable and more energy efficient to heat an entire area than heat the buildings needed specifically and locally? With the thin atmosphere, the ground is likely to be the biggest channel of heat conduction, so you would want to isolate your buildings from it as good as possible. Also, why should you not be able to thaw frozen buildings? Electric heaters are extremely easy and reliable, so if you have enough power, you should be able to turn them back on.
