SKY FARMING : Urban Farming Goes Vertical

Recommended Posts

QUOTE (nicejim @ Feb 11 2010, 08:05 PM) Each square yard of the earth's surface has a certain amount of soil. Vertical farming changes that. Light only comes from overhead between the tropics yet plants grow outside this zone, with their only source of sunlight coming from the side. The further from the tropics you go, the better vertical farming becomes.

 

Do some research on photosynthesis and you will understand why the whole concept of vertical farming is in snake-oil territory - much like electric cars as an alternative to oil. Of course the surface area that is cultivated can be increased but the amount of solar radiation in a given area for a given time is fixed. Get it?

 

As often happens when I post, I come across somewhat harshly - it is just the desire to stop people being duped - those without a basic education, especially in the sciences, are prey to all kinds of schemes which can appear attractive but which can easily be rebutted with some simple maths and common sense.

VERTICAL GARDENS are Growing up, suggests SCMP article

"Only way is Up for Vertical Gardens"

East Asia's architects are sprouting new ideas for greening cities, including vegetable gardens on sides of tower blocks.

 

"If plants can grow in the wild on the barren cliff, why not on city buildings too," asks Patrick Blanc, who was a pioneer in installing a vertical garden at the Museum of Science in 1988. Since then, he has done more green walls in: Berlin, Tokyo, London, Hong Kong, and New York, etc.

 

To house more populations, without consuming agricultural land, cities will have to become denser

 

Sky Green Farms opened in Singapore a year ago, as the world's first commercially viable vertical farm:

 

sky-greens-singapore-worlds-first-vertic

 

+ producing one tonne of leafy green vegetables every day, which are sold in local supermarkets.

+ took the inventor, Jack Ng, three years to develop the prototype for his A-G0-Gro (AGG)

+ vertical vegetable farming using a system of multi-layer troughs, in rotating A-frame structures

+ his plan is to produce 50 per cent of the Sing's green leafy vegetable consumption

+ (this is suitable for stir-fry and soups) : harvested every day, and delivered almost immediately

+ AAG's modular A-frames can also be used on rooftops
