The two story windows would provide more available light, and you would actually get more area with direct sunshine in the winter when the sun is lower in the sky (of course being offset by the shorter day.) Having the windows mirrorized on the inside would also help. If you do this right you also get a heat column that can power a "wind turbine" on the roof to provide electricity for the building.
This is not a pipe dream, btw, folks are looking at this with a mind toward implementing it. Fresh veggies in New York City in the winter? Gold mine.
Yes, high-tech solutions like this would be a good way forward. Also science based agriculture with the aim of harnessing natural biological processes, rather than industrially overpowering them, could work wonders and massively improve sustainability. I'm very interested in the concept of permaculture and the possibility of using these techniques to
re-green deserts. Farming techniques that improve soil quality, rather than eroding it, may cost more and may require more effort, but they can also have a better yield (measured per acre rather than by profit) - and especially in the long run.
