CNN Money brings us the story of Singapore-based farmer Jack Ng and his company, Sky Greens, which builds vertical farms to supply locally-grown food in an economy that is almost completely dependent upon imports. By layering the farms vertically, Ng can make better use of the little available space in Singapore, while using far less water than traditional farming methods. The rotating racks dip plants in a filtered, nutrient-rich solution. Even better, the racks use a modern version of the ancient water wheel, which allows the racks to be powered with the same amount of energy needed to power a lightbulb.
