Floating Cities and Sea-Level Rise – an unsinkable idea – Anthropoce

But Chen claims that Oceanix City will be different, partly because of lessons hes learned from working with TSI. During his time as Tahitis minister of tourism, Collins Chen helped connect his native French Polynesia with TSI to establish a self-sufficient floating city within the territorys Special Economic Zone and to test its viability as a climate-change solution. After both parties signed an MOU in early 2017, Collins Chen co-founded the Blue Frontiers company to develop and construct The Floating Island Project.

Mounting opposition from Tahitian locals to what appeared to be a floating tax-free haven for the wealthy, however, ended government support for the project in 2018. Borrowing elements from the failed project, Collins Chen moved on to found the floating cities company Oceanix, which he says will be free of the political baggage that sank the French Polynesian prototype.

Unlike TSIs autonomous libertarian utopias, Oceanix settlements will be floating extensions of host nations and subject to government rule. Most importantly, he adds, Oceanix City is being developed with a focus on egalitarian principles and environmentalism, rather than governmental reform and a bias towards the wealthy.

Oceanix has put together an impressive teamincluding MIT scientists and Danish architecture firm Bjarke Ingels Groupto develop designs based on TSIs principles of modularity and self-sufficiency. Created to withstand extreme climate events such as Superstorm Sandy, an Oceanix City comprises hexagonal modules constructed from hollow concrete caissons that buoy the flood-proof city upwards in the event of rising waters.

Since the company will market the Oceanix City concept to governments worldwide, modularity is a key feature of the customizable design. Prefabricated off site, the 4.5-hectare floating platforms, which house 300 people each, can be joined together in a variety of configurations, with modules added or subtracted as needed. Six combined modules form a village, while six connected villages add up to an Oceanix City of 10,000 residents.

In reframing floating cities as a climate-change solution, Oceanix has earned support from the UN. Packed to the gills with sustainable techfrom locally grown food to water-to-energy plants, Oceanixs floating city redesign promises zero-waste, self-sufficient living. One notable example is the unique application of Biorock to anchor the settlements while simultaneously creating artificial reefs for marine ecosystem regeneration. Developed in the late 1970s, the mineral-accretion technology uses electric currents in seawater to crystallize dissolved minerals into heavy limestone coatings that are two to three times stronger than ordinary concrete.
