If you want to use natural lighting, you're going to need to increase the light catchment area beyond the area of the building. One layer of crops already wants a full dose of sunlight, so splitting the amount of solar energy which hits a single building between 10 floors will just leave each floor with 10% of what it actually needs. About the only way I can think it could possibly work is if the roofs of all the buildings around the vertical farm were fitted with sun-tracking mirrors, but that assumes both that the roofs are available and not used for, say, solar electricity generation, and that you don't want to put vertical farms too close together.
- _delirium 16y ago> One layer of crops already wants a full dose of sunlight Is that actually true? Crops are grown in a pretty wide range of locations, and sometimes the same crops are grown in different locations with quite different insolation. Surely there must be at least some set of [location,crop] pairs where the crop needs less than the full amount of sunlight available in that location?
- regularfry 16y agoSure, but you'd then be limiting the applicability of the idea quite a lot, which goes very much against the idea that this can be used to chop delivery distances down. I also find it hard to believe that you could find 10 layers' worth of crops this would work with. Two or three, maybe, but I would be astonished by more than that.
