Yep, it's all about cost of energy. The solar farm that powers a vertical farm will always take up more space than the vertical farm saves.
We have a nice podcast episode about this, maybe this interests you: https://www.predictions-podcast.com/2020/03/29/vertical-farming-10-yearsr-or-1000-years-away/ https://www.predictions-podcast.com/2020/03/29/vertical-farm...
- SamBam 6y agoI can't listen to your podcast right now, but solar panels are more efficient than photosynthesis, and you can produce the wavelength of light needed for plants by LEDs using a fraction of that power, so what makes you say that the solar farm that powers a vertical farm will always take up more space than the vertical farm saves?
- konschubert 6y agoYou're right, I was generalising a bit in my above comment. The wavelength - focusing argument actually comes up in the podcast and we agree it might possibly offer a way out of the energy trap. PS: Feel free to subscribe now to listen later ;)
