I don't see how vertical farming can make sense. There is only so much sunlight striking the ground and you just changed the angle and so shaded something else.
Read the article - it's indoors.
That doesn't change anything. unless you have a perpetual motion machine the energy comes from somewhere.
Eh?
On second thoughts, don't bother.
Goodbye.
your intuition about insolation is correct, but plants are largely not sunlight limited, rather they are nutrient limited. a vertical farm increases soil density and is also an engineered greenhouse.also in this case the light is from grow lights, so can be powered by say, wind, or nuclear.
some plants are light energy limited but these are often not major crops.
