I saw this image first in an Autodesk advertisement in a magazine. It's cool to see a company showcase something like that in an ad; i guess the drawing was made with Autodesk. Whatever, that's not the important part. Vertical farming is apparently a well-studied concept. This particular one is called, "The Living Tower," and it's by Pierre Sartoux. It's an interesting idea, but thinking about it too much makes me mad. seriously? scraping all the topsoil off plantable land to make housing developments, then building skyscrapers to house farmland. it seems like people have their priorities backward. nevertheless, it will sadly become increasingly relevant.
More on vertical farms.
