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.
Love it, but it has pretty niche utility.
It's great for improving frest fruit/vegetable access in small urban communities, without massive transportation costs and preservative use.
Also very cool for small, isolated environments like ocean voyages and space, where production space is severely limited.
And extremely interesting from an ecological perspective when combined with a full circle microsystem, as in aquaculture.
But overall, it remains wildly inefficient for large scale agriculture needs.
I'm hoping to see more successful large scale operations perhaps with some aspects of aquaculture/aquaponics integrated
