The fabulous SKY GREENS in Singapore is one of the world’s first commercial vertical farms. Designed, owned and operated by 50 year-old engineer, Jack Ing, this is a thriving and quite beautiful farm.
With 5 million people on a small island city, Singapore is one of the most densely populated cities on Earth. With just 250 acres of farmland left, they grow just 7% of their food, an expensive and precarious position to be in with a reliance on cost, energy and pollution intensive transport of food, especially fresh vegetables from distant points around the world. Singapore’s goal is to produce 10 to 20% of their fresh food locally in the near term.
The 4 story tower which rotates vertically, runs off of a compact gravity powered water wheel and the entire tower costs just $3./year to run (about as much as a 60 watt bulb).
It is estimated that 80% of the world’s population will live in cities by 2050 with food a critical factor. This prototype points the way for healthy local production that is 10 times more labor, energy, water and input efficient than commercial agriculture. Aside from feeding people, being a locovore (eating organic, fresh local food, emphasis on the local) is an important part of reducing greenhouse gases and climate change.
Check it out…and enjoy. If you live in a city, please start your own SKY GREENS and then expand upward and out to the people around you.
