So we have one algae tank up and running for water reclamation. According to Jo, the vat is producing 60 units of water per day utilizing the colony's "output".
A second algae system is currently under construction. Since all the algae types utilize the same basic tank system we can discuss what kind of algae we should grow in the second tank system. The food, bio-plastic, and bio-fuel algae only need pure (ish) water to suspend in and work by photosynthesis, so we will not be taking away resources from water reclamation
If I recall correctly, Jo votes that we should be growing the food algae next. Food is an issue, to be sure. But I would like to argue that we go either for a second water tank (if colony output will adequately supply it) or bio-plastic.
This is based purely on anecdotal and casual observation that mining, smelting, and forging is incredibly thirsty work. More so than gathering and processing food and water. I also have to consult the Spire Network on how much water the three non-poop-eating algae will need to start and how often/how much will need to be replenished.
Just like the "Happy Farmer" experiment, we should figure out how much food and water a happy miner/smelter/forger needs.
I suggest we should only go with the plastic producing algae if we're confident the plastic would be good for making vats for the algae so we can allocate those precious ore resources to other uses. We might even be able to reclaim some of the previously used metal by, for example, replacing the metal blades on the windmill with plastic ones.
