Lots of cities have farmers markets, but most — if not all — of the produce comes from rural farmers that use oil-intensive methods of transportation to cart around their food. With 80% of all people on the planet projected to live in cities by 2050, food production will have to move into cities if it is to remain cost-efficient. A Swedish-American company called Plantagon has conceived of an incredible solution: a massive urban greenhouse contained within a geodesic dome. The vertical farm, which consists of a spiral ramp inside a spherical dome, is currently in the development stages.
According to Plantagon, the farm “will dramatically change the way we produce organic and functional food. It allows us to produce ecological with clean air and water inside urban environments, even major cities, cutting costs and environmental damage by eliminating transportation and deliver directly to consumers. This is due to the efficiency and productivity of the Plantagon® greenhouse which makes it economically possible to finance each greenhouse from its own sales.” No word on how exactly the Plantagon system works, but the company says that consulting engineering firm Sweco has helped untangle the technical kinks of the project. Plantagon hopes to have its first vertical farm up and running within three years.
