Great video. My major takeaway: vertical farming is not economical for many crops due to the cost of electricity. Another takeaway: vertical farming might work well for some crops that are mostly water by weight and have low energy requirements (e.g. bazel, lettuce).

I wonder how the numbers work out. I guess they'd want to avoid (1) limiting themselves to certain crops and (2) limiting themselves to specific geographical areas in order to make their market as large as possible.
