It seems like NYC is a poor place to house this. Ideally, if you wanted it to be viable and not just a proof-of-concept, you'd find somewhere with cheap electricity, cheaper land/rent than NYC[1], and expensive fresh produce. My guess is Iceland would be a good spot, and I'd be a little surprised if they didn't have something like this already in the works. Iceland also has another side benefit for traditional greenhouses: the ground can naturally heat the houses. http://www.nea.is/geothermal/direct-utilization/greenhouses/
