Vertical farms don't make sense, and never will, except as a curiosity/novelty/luxury product. There's only so many calories you can grow with the incident sun

Vertical farms don't make sense, and never will, except as a curiosity/novelty/luxury product. There's only so many calories you can grow with the incident sun on a piece of ground.

If you grow under the sun, vertical systems and hydro-/aeroponics still make a lot of sense, IMO. Check what these guys are growing under the sun in grow towers: https://youtu.be/GpKGbXWepAs https://youtu.be/GpKGbXWepAs I think this would be impossible to reproduce with traditional horizontal farming.
- PeterisP 4y agoThey make all sense given cheap energy. For example, Iceland grows most of its tomato consumption locally around the year despite a lack of sun in seasons like this one (currently 4-ish hours of not-that-strong daylight), doing that under artificial light in greenhouses, getting both heat and electricity from cheap geothermal power sources. So when at some point in future we manage to get cheap renewable replacements to fossil fuels, all of this becomes very relevant.
