This chapter ties up the themes in the book overall by examining at a top level of the factors that affect space farm designs, then adds top-level concerns for space farms, including choosing locations to build space farms, getting the inputs to start the mass flow cycle, construction of the farm, getting crop organisms to a distant space farm. There is also a discussion of how different crop products and farm input may be part of a larger space economic web and outgrowth of current space efforts. Finally, the chapter covers research topics that will lead to better farm designs.
