This chapter covers the various devices, mechanisms, and structures that are needed to control and contain space farms. Starting with devices to move mass, such as pumps, fans, then contain mass in vats, tanks, and columns. Other machines are required to separate components of mass, such as filters, settling tanks, distillation columns, and other separation technologies. Condensers and coolers are key to controlling humidity. Injecting gases via aeration is via combinations of pumps and various structures are important for many purposes. Lighting has many purposes and shapes in the farm, such as sterilization, plant growth, and safety. Thermal control and heat rejection are critical to control growth environments. All these machines use electricity, which the chapter examines as energy that must be modeled for design. Finally, the chapter covers control software and systems, which can use artificial intelligence in various roles.
