  • DO YOU EVER GET THE URGE TO JUST BUILD A NEW WORLD?

  • LIKE, FROM SCRATCH?

  • TO RE-THINK THE UNSUSTAINABLE PATTERNS THAT LED TO OVERCROWDED CITIES, DWINDLING NATURAL

  • RESOURCES, AND THE DRAMATIC IMPACTS OF CLIMATE CHANGE?

  • SOME SAY WE SHOULD JUST CUT

  • OUR LOSSES AND MOVE TO MARS.

  • AFTER ALL, WERE QUICKLY RUNNING OUT OF FRONTIERS HERE ON EARTH EXCEPT, OF COURSE,

  • THAT SALTY ONE COVERING 70% OF OUR PLANET.

  • HOW CLOSE ARE WE TO LIVING IN THE OCEAN?

  • WEVE ALREADY BUILT UNDERWATER HOTELS AND SUBMARINE LABORATORIES,

  • AND WE KNOW WHAT YOURE THINKING...

  • AN ATLANTIAN METROPOLIS WOULD BE AWESOME.

  • BUT THERE ARE A FEW REASONS BIOSHOCK IS PURELY FICTIONAL. INTENSE PRESSURE,

  • A DISTINCT LACK OF OXYGEN AND LIGHT, MAKE THIS EXTREMELY EXPENSIVE ON A LARGE SCALE.

  • BUT WHAT WE COULD DO IS BUILD A CITY ON TOP OF THE WATER.

  • IN FACT, COASTAL CITIES HAVE BEEN EXPANDING INTO THE OCEAN FOR DECADES, OFTEN RELYING

  • ON DESTRUCTIVE LAND RECLAMATION TECHNIQUES.

  • BUT WHAT IF WE SIMPLY DESIGNED CITIES TO FLOAT?

  • FLOATING VILLAGES EXIST ALL OVER THE WORLD, AND OVER THE PAST FEW DECADES, SOME WILD IDEAS

  • HAVE SURFACED FOR SCALING THAT UP.

  • It's not about kind of a rarefied, resort-like, free government, totally independent world

  • 200 miles off the shoreline.

  • It's really about creating a working neighborhood that could sit within a protected harbor,

  • adjacent to a dense coastal city.

  • 90% of the world’s major cities are going to be dealing with the effects of sea level rise

  • in the coming decades.

  • AS IT BEGINS TO SWEEP OUR FOUNDATIONS AWAY, COULD SEA LEVEL RISE FINALLY PROVIDE

  • THE FOUNDATION NEEDED FOR SUCH AN EXPERIMENT?

  • A COMPANY CALLED OCEANIX THINKS SO.

  • ALONGSIDE INTERNATIONAL CONTRIBUTORS, OCEANIX AND ITS TEAM

  • OF DESIGNERS AND ENGINEERS RECENTLY UNVEILED AT THE UNITED NATIONS

  • A CONCEPT FOR A SUSTAINABLE FLOATING CITY.

  • THE DESIGN AIMS TO SUPPORT 10,000 RESIDENTS, ACCOUNTING FOR FOOD, WASTE, WATER, ENERGY,

  • AND MOBILITY.

  • We wanted to make sure that we would provide all the resources that the people would need

  • to really feel like they're part of a vibrant collective system.

  • The design of Oceanix city is a move away from the very flashy, futurist kind of utopian

  • proposals we see a lot.

  • It reflects the kind of utopian architectural style that has been developed

  • maybe in the last 20 years called New Urbanism

  • to really give that nostalgic neighborhood feel to it.

  • THE TEAM STARTED WITH A SIMPLE CHOICE: THEY OPTED FOR A PONTOON STRUCTURE,

  • FOR MORE SHALLOW, SHELTERED HARBORS, OVER A SEMI-SUBMERSIBLE DESIGN

  • SUITED TO THE OPEN OCEAN.

  • THESE STRUCTURES, BESIDES BEING FLEXIBLE AND MODULAR, ARE RESISTANT TO

  • TSUNAMI AND EARTHQUAKE DAMAGE

  • PROVIDED THEYRE DESIGNED FOR THE PHYSICS OF WATER.

  • For any floating body on a water surface, there are actually six forces that act on it.

  • You've got the surge force, where an object sort of slides forward and backwards.

  • You've got a sway, where it slides from side to side.

  • You've got the heave, where it goes up and down;

  • a roll or a pitch or a yaw, where it rotates horizontally.

  • The hexagon just ends up being a great way of approximating the stability of a circular

  • shape in the water.

  • It really lends itself well to combining into fields, or rings, in order to, when you

  • combine six of them, create a sheltered harbor.

  • Then those kind of villages, or clusters, can combine to create an even larger sheltered harbor.

  • That kind of system of growth continues in a fractal pattern.

  • OKAY, SO AN AQUATIC, EARTHQUAKE-RESISTANT BEEHIVE

  • THAT GROWS OUTWARD LIKE A SNOWFLAKE?

  • I’M ONBOARD.

  • BUT WITHOUT WORKER BEES AND A QUEEN, HOW DOES THIS COLONY SUSTAIN ITSELF?

  • You could harness energy if you had a decent wind source through offshore wind turbines.

  • There's also this technology called OTEC, basically what it does is that it takes the

  • differential between the surface temperature of the sea and deeper waters to drive cooling

  • that creates an energy source.

  • IN ADDITION TO WIND TURBINES, OCEANIX CITY WILL RELY ON SOLAR PANELS AND WAVE ENERGY.

  • BUT WHAT THE TEAM BELIEVES IS MOST CRUCIAL IS A MIX OF HIGH- AND LOW-TECH SOLUTIONS,

  • PLUS SOME MINOR LIFESTYLE ADJUSTMENTS BY ITS RESIDENTS.

  • The plan is to embrace a plant-based diet.

  • When you eliminate animals from a diet, we can, right off the bat, start saving our resources

  • of land and water.

  • We are relying on greenhouses, orchards, and also aquaponics and aeroponics systems which

  • will be used within the platforms.

  • We are going to reduce the amount of waste we create by having reusable packaging throughout

  • the island and have as little waste created as possible.

  • We will recycle, we will reuse, and we will compost.

  • THOUGH THIS MAY JUST SEEM LIKE A QUICK FIX FOR OUR OVERDEVELOPMENT PROBLEM,

  • OCEANIX WANTS TO CONSIDER LONG-TERM SOLUTIONS THAT HELP THE MARINE ECOSYSTEM TOO.

  • You would really want cutouts to allow sunlight to penetrate.

  • In terms of the pontoon structures, some of them use gill technology that allows water

  • to actually pass through the structure minimizing the impact on the environment.

  • We're working with the Global Coral Reef Alliance on a technology called Biorock, which takes

  • a steel cage, puts a very small amount of electricity into it.

  • That electrical charge helps attract mineral deposits, which then attract coral and marine life.

  • By building up reefs, and itself acting as a kind of wave break, it can actually start to help

  • dampen the effects of storm surge, and waves, and erosion on existing coastlines.

  • I think what floating structures offer is quite a good intimacy with the water.

  • There's almost the sense of accountability or ownership of that particular patch of ocean

  • that you want to preserve.

  • BUT WHAT IT SEEMS EVERYONE IS AFTER AS THEY FLOAT THESE PROPOSALS

  • IS A CHANCE TO START FRESH.

  • The modular approach to this design allows the city to flex its muscles in different ways.

  • And fit the needs not only of the city itself, but of the coastal city that it's adjacent to.

  • The lessons that we learn on the water, how we're growing food within a more compact

  • footprint, how we're generating our energy, how we're dealing with our waste are then

  • lessons that can actually then be exported back to land.

  • BUT WE WON’T IMMEDIATELY JUMP INTO A FULL-FLEDGED CITY RIGHT OFF THE BAT.

  • THESE PROJECTS COULD START OUT IN A FEW DIFFERENT WAYS.

  • If you're talking about satellite installations you would really be looking at the biggest

  • corporations in existence right now, which are tech companies.

  • Something like Google or Facebook creating a campus or a massive data center on a floating

  • platform off somewhere.

  • In a lot of ways, I think Disney would be perhaps the best candidate for creating a

  • floating resort city.

  • The first larger village for Oceanix could be something like a university.

  • SO

  • HOW CLOSE ARE WE TO LIVING IN THE OCEAN?

  • I think we're closer than you might think.

  • Once we have a partnership with an interested city or state, we'll be able to pretty quickly

  • get a first prototype in the water and then really just build on it from there.

  • We work on a lot of different kinds of climate change adaptation projects.

  • In the case of New York City, we have a really dense, existing coastal neighborhood.

  • But what the Oceanix city provides is a tool to adapt.

  • I think we will see a lot of cities expand onto floating parts of themselves in the next 20 years.

  • The technology is there... let's try and make sure that we don't need for it to be so pressing

  • before we actually create these structures.

  • Let’s create it in anticipation of the need that will come.

  • FOR MORE EPISODES OF 'HOW CLOSE ARE WE?'

  • MAKE SURE TO CHECK OUT THIS PLAYLIST, AND LET US KNOW IN THE COMMENTS WHAT YOU WANT

  • TO SEE US INVESTIGATE NEXT.

  • THANKS FOR WATCHING!
