A 'Vertical Greenhouse' Could Make a Swedish City Self-Sufficient
by Julie Ma
The greenhouse is a conical glass building that uses an internal "transportation helix" to carry potted vegetables around on conveyors. As plants travel around the helix, they rotate for maximum sun exposure. Hassle says the building will use less energy than a traditional greenhouse, take advantage of "spillage heat" energy companies cannot sell, digest waste to produce biogas and plant fertilizers, and decrease carbon dioxide emissions while eliminating the environmental costs of long-distance transportation. And growing plants in a controlled environment will decrease the amount of water, energy, and pesticides needed.
The greenhouse, which will open in late 2013, is already serving as a model for other cities—Plantagon hopes to install the transportation helix technology in regular office buildings around the world, eliminating the need to build entirely new structures. The tallest models even have a name: Plantascrapers.
