PBS Video on Vertical Farming in Singapore

This PBS video features vertical farming in very populated Singapore. The farm, Sky Greens, is four stories tall and consumes very little energy. Singapore grows only 7 percent of its own fresh produce on a last remaining field of 250 acres.

At Sky Greens, the produce is watered using an ancient water wheel technology “with a modern twist”. The closed loop hydraulic system uses about the same amount of electricity as a 60 Watt light bulb.

Sky Greens costs of operation are only a quarter of the conventional farm’s, it is ten times more productive, and uses less water and land. The commercial venture has funding to quadruple capacity in the near future. In Singapore, ninety percent of the food comes from foreign countries. The government is behind technologies like this to help with food sufficiency, but realizes that it needs to become cost competitive.
