Interviewed a couple of years ago at a vertical farming startup. All the usual talk about making the world a better place through technology (and machine learning for some reason). I asked where the electricity came from, turns out they were literally burning coal to grow some salad not very efficiently. Hydroponic farms have been studied for decades, they are super optimized but they have their limits as well - see the 10 GBP bell peppers in supermarkets today. I would really like to know how the numbers look like when comparing traditional hydroponic with these hyper-local vertical farms.
