Ocean Spiral – an underwater city

Japanese engineering firm, Shimizu Corp, has announced plans for "Ocean Spiral", an underwater city that would form a nine mile (15 km) structure plunging down to the sea floor. Costing three trillion yen ($25 billion), it would feature residential, hotel and business zones at its top, with resource development facilities at its base to harvest rare earth metals and minerals. Electrical power could be generated by exploiting the wide differences in water temperature between the top and bottom of the ocean. Construction would be achieved with industrial-scale 3D printers using resin components instead of concrete. Shimizu believes the technology required for this project could be available by 2030. The company has been behind a number of previous futuristic concepts, including a "Luna Ring" of solar panels going around the Moon and a floating botanical city that could absorb CO2.

“We had this in Japan in the 1980s when the same corporations were proposing underground and ‘swimming’ cities and 1 kilometre-high towers as part of the rush to development during the height of the bubble economy," says Christian Dimmer, assistant professor in urban studies at Tokyo University. “It’s good that many creative minds are picking their brains as to how to deal with climate change, rising sea levels and the creation of resilient societies – but I hope we don’t forget to think about more open and democratic urban futures in which citizens can take an active role in their creation, rather than being mere passengers in a corporation’s sealed vision of utopia.”
