It is interesting work, but I feel like this is mostly just marketting fluff. Even reducing energy cost by 75% by switching from photosythesis to some hypothetical chemical food, that still comes out to about 400,000 watts per acre for 16 hours a day. Because using high efficiency grow LEDs you need 1.5 million watts minimum per acre for staple crops. I don't see how we are anywhere even close to the energy requirements needed for vertical farming to be anything but a gimmick for multiple decades.
