I probably explained it poorly. My startup communities are very small. Less than 60 residents. 2-3 habitats, a few farms, 1 or 2 atmosphere plants, blue lab and factory, a concrete factory and one steel factory. Warehouse and spaceport.
As I try to progress up the tech tree into green and appliances, I see that food has begun to get low and finally the habs will start to downgrade. The farm efficiency that started out as 100% is down to maybe 20%. Adding additional farms just seems to lower the efficency rather than increasing total production. Actually, all of the processors (O2, mines, factory’s) behave this way, efficiency drops over time and adding capacity does not overcome the problem. I see the futility of continuing when the efficiencies get down int single digits so I end that attempt and try again with different technology focuses, but that is not the problem.
Is keeping everything compact the answer? I haven’t focused on that yet, but maybe concrete delivery for new construction happens without the need for roads and can be separated, but all the other necessities need interconnected roads. My start up is so small that traffic is not an issue and its hard to see how distance can be the problem as everything is located in a 4 block square.
