Plantagon seems to have traded in its initial geodesic dome design for a sheer tower that both contains and showcases the plants growing inside. This prototype building will be called the International Centre of Excellence for Urban Agriculture, and it will be a place for scientists to test new technologies aimed at improving urban farming.
Inside the massive glass walls, vegetables will be grown in pots and then transitioned to trays positioned around a giant central helix. The plants grow as the trays slowly migrate down the central core and are ready to be harvested once they reach the bottom. Plant residue and manure will be collected along the way and transformed into biogas to run the heating and cooling systems of the greenhouse. Scientists want the vertical farm to not only grow food but also help in developing sustainable solutions for energy, heat, waste, and water issues of daily city life.
