A relevant previous submission to HN: https://news.ycombinator.com/item?id=25554941 https://news.ycombinator.com/item?id=25554941 The article linked presented the the efficiency of vertical farming in terms of produce/area. But as was pointed out in some of the comments on that article the cost of the greens grown on vertical farms was in the range of $15/pound [1].
