My most ambitious project so far: 3-building complex to make 840 batteries/min. Donut-shaped building is water extractors. Rectangular building (3 levels + roof) is logistics, drone ports, and train stations to collect bauxite, sulfur, coal, raw quartz. Hexagonal building (5 levels) is battery production. All water and silica produced is recycled back into battery production. All unused bauxite, coal, quartz available to deliver elsewhere by drones. 33 Drones available to deliver batteries, as well as a train with 2 freight cars (priority given to delivery by drones). All items not being delivered somewhere are sent to Awesome Sinks. Hypertubes connect all levels to central "observation deck" as a transport hub.
