Rachel Nuwer – Will We Ever… Live In Underwater Cities?
bbc.com. September 30, 2013. There is growing interest in deep sea mining for minerals and metals, especially around island nations such as the Cook Islands, the Seychelles and Tonga. The Chinese in particular have been investing in deep sea expeditions to investigate the viability of mining manganese nodules, rocks that contain nickel, copper, cobalt, manganese, gold and also valuable rare earth minerals. This work is being done remotely, however if large-scale operations do go ahead they might be simplified by having people continuously on-site at depth, according to Koblick.
Then there are those who see underwater living as a way of preserving our species in the event of an apocalyptic catastrophe. In the event of a disaster that put paid to human life, communities could perform reverse versions of Noah’s ark. With that in mind, Philip Pauley, a futurist and the founder of the London-based visual communications consultancy Pauley, designed the self-sustaining habitat Sub-Biosphere 2. His design includes circular structures that could be floated out to sea and then sunk, creating a haven for 50 to 100 lucky people.
