Vertical farms solve a problem but their problems have not been solved.
Vertical farms still have unsolved problems. There is not enough land to grow fruits and vegetables at scale; the Salinas Valley is full and hugely per acre. Vertical farms could solve that, potentially.
Below is a starry eyed story by an ignorant reporter, who was told by an editor to go back and include other examples, which he did at the end of the article. I’ve been that ignorant reporter in a rush. https://www.forbes.com/sites/johnkoetsier/2020/11/20/this-2-acre-vertical-farm-out-produces-750-acre-flat-farms/
The story leaves me with these questions, which may not be the right ones. Are there vertical farms in that list that have solved the need for extraordinarily high yield with the nexus of also creating food quality that is the central one this entrepreneur is focusing on? What about microorganisms and soil health; do they exist in a vertical farm ? What are the energy and water costs, what are other externalities like that? A second story that was not wide eyed about blue sky potential but that looked at what can overcome the biggest system blockages would be worth it.
