Vertical farming, the best solution to support an ever growing population or just a scam?
IMHO it has a lot of potential but not being able to grow grains really is something that should be tackled sooner rather than later. But I could see this being used by self sustaining communities to provide lots of food while using very little space. And it's technically more environmentally friendly than just using vast stretches of land to produce the same amount of food.
Freshness is such a key thing, the difference is taste is so significant especially with herbs and greens so enabling people to have an easy to manage and small footprint little tower of good food in their garden, balcony, or similar would be really good especially for renters if it could be packed up for transport then resembled in the new location.
An overlooked factor that I have no idea how to quantify is that access to tasty greens may reduce meat consumption.
