The Swedish company Plantagon will show how to grow more food in less space when it opens its first urban greenhouse in 2013 in Linkoping, a city some 180 miles from Stockholm. The plan is to grow vegetables in a turning helix with minimal water, energy and the need for fertilizer. With the world’s population to top 9 billion by 2050 — and with 80% of those people projected to live in cities — finding innovative, cost effective, and environmentally friendly ways to supply food to cities is a major challenge.

According to Plantagon, the farm “will dramatically change the way we produce organic and functional food. It allows us to produce ecological [resources] 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.
