As for food, we do plan on growing it outselves. At start, we will be using the single vertical farm (more like ‘angled farm’) we have to grow enough food for 100 people, supplemented by catch from the sea. Imports will be necessary until we can get our first produce. Then when the population increase and that single farm is no longer capable of sustaining our population, we’ll get a separate tanker, converting it into hydroponics farm. So the city itself can be used for aesthetics.
In the future, if the project succeeds, we’ll have a second district where we raise livestock like goats and cows. Now, I know people will say you can’t raise cows at sea. That’s true, but we’re not raising them on a ship or enclosed containers. We’re raising them on the second district, and a district is huge. A single district is double the size of Monaco, with the designer wanting to build bigger. I had to stop him from his delusions because if we build bigger, we won’t ever see it float in our entire lifetimes. The cow will feel like it’s living on an island, and there’s no problem raising cows on an island.
Additionally, we can also build fish farms in the future, but this is up for discussion still. We will decide if we need it when Risenia is finally floating. We won’t be needing it when we start.
Theoretically, our system should allow us to scale it to support our population, making ‘just enough’ for a middle income lifestyle at every step of the way. If anyone wants more, we can import food from somewhere. We will aim to grow or fish enough to provide citizens with the recommended daily nutrient intake on an average day.
Just think of Risenia as something like USS Voyager from Star Trek. There is space limitation, but because it’s big and our population is small, we still have a lot of space to grow. However, once all that space is used up, we’d need to get additional ships to sustain our livelihood.
