Mesmerizing to look at, self-sustaining underwater cities will be a part of our world by 2030 – merely 15 years away. Japan-based Shimizu Corporation believes the solution to a shortage of land for housing lies in expanding offshore – literally. It makes sense; approximately 70% of the earth’s surface is covered by the ocean.
Shimizu’s concept seeks to ‘harness the power of the deep sea…to resolve five current crises revolving around food, energy, water, carbon dioxide and natural resources’.
Self-sustaining underwater cities comprising a floating dome and helical structure descending to the ocean floor could be home for up to 5000 people each.
The structures would be built using 3D-printing technology, and would also utilise hydraulic technology to desalinate water for consumption. As if that wasn’t impressive enough, micro-organisms could be used to turn carbon dioxide into methane, which would fuel power generators along the 14km-length of the spiral.
Shimizu predicts that the helical structure will cost NZ$36 billion to build.
This is SUCH a fascinating read:
