The increasing awareness about the environment has challenged the architects and designers across the globe to come up with innovative ideas. Belgian architect, Vincent Callebaut has proposed a futuristic ocean building made from 3D-printed plastic waste which extend 1,000 meters below the water’s surface. Aequora, the water city would be situated off the coast of Rio de Janerio and derives its name from a bioluminescent jellyfish called aequorea victoria.Â The architect is well aware of the saying that â€œwe donâ€™t own the Earth, we have just borrowed it from our childrenâ€ and this is the inspiration behind the project. Vincent presents the idea to the world in the form of a letter written by the â€œaquanautâ€ named Oceane based Aequora addressed to all the people and dated 24th December 2065. The structure would be made from algoplast, a composite material made algae and rubbish. It is designed to house 20,000 aquanauts in 1,000 towers.Â The entrance to the underwater environment would be done with the domed marines measuring 500 meters in diameter. Life underwater would be bizarre for you need gill masks to breath underwater, food would come in the form of farmed algae, plankton and mollusks, orchards and vegetables gardens would be grown on top of the conch-like structures, transport system powered by seaweed, plant-covered â€œfarmscrapersâ€ and stunning and quirky environment that you would experience all around.
