# Vertical Farming The question is a whole optimization problem - at what point does the supply chain shortening + productivity gains balance with the increased land costs, construction, equipment? * Could you use robots to get the calories per acre cited [[How Asia Works]] for labor intensive things? * How much efficiency gains could you get if you could control CO2 precisely? Do people do this in greenhouses already? * Does the “expose growing plants to electric fields” thing actually work? * Has anybody run the numbers on energy building costs?
