I found this on Inhabitat recently but haven’t had a chance to post about it before..

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’ consists of a spiral ramp inside a spherical dome and is in development. Plantagon hope that the farm “will dramatically change the way we produce organic and functional food” and they hope to have their first farm up and running within three years.

It’s a bold project with interesting ideas but no word yet on the inner mechanisms. It looks fantastic though so I’ll be watching this one with interest!
