Major steps towards better, sustainable and affordable food production free of environmental challenges have been taken, with the "world's first farm to grow indoor, vertically farmed berries at scale" opening in Richmond, VA. It's backed by an international team of scientists that see this new…
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.
Let’s assume the energy for lighting comes from solar. Panels are only 20% effective. Nor your vertical farm needs 5x the space than a basic farm, and you still have to pay for it instead of using free sunlight.
There is some video on YouTube from some professor who works for nasa on growing plants in space about this topic.
Sure, but where does the energy for that light come from? If the answer is burning things (this is the most likely answer today!) then you are making the world worse. Renewable answers all go back to the sun so why not use the sun directly and avoid all the inefficiencies from turning the sun into electric and then back into light? Which leaves nuclear - which is dieing because of expense.

Read the article - it’s indoors.
Artificial lighting exists.

Photosynthesis only uses a couple frequencies. Using solar to generate electricity and feed that into target LEDs can be significantly more efficient.
