Off the coast of Rio de Janeiro, Brazil, a city of the future will be 3D-printed. Up to twenty thousand people will live here. The purpose of the project is to study the ocean.

The Aequorea project was proposed by the visionary architect Vincent Callebaut. According to his idea, the jellyfish-shaped buildings of the city will be submerged in water. Each building will be complete with recycling plants, production laboratories, offices, co-working spaces, workshops, research centers, marine farms, organic farming, community gardens and vegetable gardens.

The Great Pacific Garbage Patch is called the seventh "continent" of the planet. Approximate estimates of its area range from 700 thousand to 1.5 million square kilometers at least. Aequorea will be built of recycled plastic waste and algae, using 3D-printing technology.

The project author’s concept envisages people travelling in ships and submarines powered by biofuel. Energy and food will be provided by algae, plankton, and shellfish, which are planned to grow on the island.

"Never forget this: the oceans produce 50 % of our planet’s oxygen. They are its most active lungs!" the project’s website states[59].

MALMÖ, SWEDEN, THE REAL CITY OF THE FUTURE

COUNTRY — Sweden

The city of Malmö, Sweden, is already being called the city of the future, because this is where you can see a synergy between different approaches to urban problems.

Malmö has more than 400 km of bicycle paths and several thousand parking spaces for bicycles. Bicycles are used for 40 % of all trips to work. By 2030, the city wants to achieve full energy independence, increasing the share of alternative energy use to 100 %, according to the city’s municipal program.

In the 1990s, Malmö was known as a port in Southern Sweden; today it is an IT, innovation, ecology and tourism hub. It is all about biofuels, bicycles, and green roofs. The city took over its own restructuring and renovation. The harbor was rebuilt, the labyrinths of industrial shipyards were cleared away and redeveloped with 600 houses, stores, and office buildings equipped with solar panels and wind turbines made of eco-friendly materials.

All homes are connected to a circulating water system, where the same medium is used for heating in the winter and for air conditioning in the summer. Garbage shredders are installed in every kitchen in Malmö. The resulting material is then used as biofuel for cars and urban transport. Food waste is also transformed into biogas, which replaces the traditional natural gas at home. The Malmö authorities even put ashes to work, the Futurist portal reports[60].
