With a skyscraper farm, the idea is that one can control the environment and manner of producing crops. Unless the building is wiped out by tornado or earthquake, vertical farms have the potential to reduce weather-related crop failures. And with modern engineering, one could set up an elaborate system of rainwater reclamation and filtering to avoid water runoff pollution. Plus, skyscrapers go everywhere. You could have towers in Tokyo, London, Shanghai, Dallas, or where ever, growing organic goods. Locally-produced organic goods sans the transportation premium and carbon emissions–now that has the potential to be disruptive! Vertical farms use artificial light and with the right combination of renewable energy power a building, I could see this being a legitimate endeavor. Experts suggest we’re about 15 years away from realizing something like this, but hey, it’s not one of the worst ideas I’ve ever heard.
