To combat growing population demands, Swedish designers have developed a Skyscraper Farm concept that would maximize food production with a minimal footprint. The Swedish city of Linkoping has already begun construction on one such facility, according to a new report.

This glorified greenhouse was designed by Stockholm-based Plantagon. The much-discussed concept is essentially a central, structural cone that supports wrapping, ramped conveyor belts. The belts carry plants to optimally lighted areas or to growing and harvesting stations within the farm. The entire system is surrounded by a giant glass sphere.

The building is designed to collect excess heat and CO2 from a neighboring power plant to use for heat in the winter. It will also produce combustible methane which can reportedly be used for energy as well.

The spheres range in size from five to 25 stories. Plantagon is confident that the farms will each be able to feed tens of thousands of people per year.
