Sorry, but in every example of vertical farming I've seen, there's nothing that actually works. Nearly all of the farms and companies I've visited and been exposed to use a lot more water and energy (in all forms) compared to a conventional farm. The only appeal I see are for places with limited agricultural land space such as Singapore or the Netherlands, or arid regions such as the Middle East or Central Asia. Even then, it's much cheaper for most of these places to simply import from abroad.
