Such a large problem requires a large solution. Enter Plantagon, a company that aims to bring massive greenhouses to major cities and maximize the structures' use of space through vertical farming. Conceived in 2004, Plantagon partnered with SWECO, a Swedish engineering firm, to turn an impressive concept into an equally stunning model. The idea is quite simple: a spherical glass structure holds together a series of planting boxes arranged atop a spiraling ramp; seeds are planted at the base of the farm and collected 30 days later in their ripened state. The vertical component of the model allows a greenhouse of 10,000 square meters to grow 100,000 square meters worth of produce."Our concept actually looks much more complex than it is," says Plantagon CEO Hans Hassle. "Realizing the concept is therefore only a question of finding a place and a market to establish them."
