I came across a very interesting National Geographic article with some really great ideas for future ocean based structures and a lot of them are pretty amazing. Some of the ideas actually exist or are already in progress, some are not too far away from today's technology, and some may never be possible.

Each of them have their own potential flaws but they all have a useful purpose as well. I thought I should share this since they provided some incredible pictures with the proposed ideas.

The Seascraper

Touted as an eco-friendly floating city, the Seascraper (pictured in an artist's conception) is among a raft of concepts for sustainable offshore settlements. With more than seven billion people on the planet, mass migrations to cities, and increased risks of flooding and sea level rise, more and more architects and innovators seem to be weighing anchor.

(Related: "Sea Levels Rising Fast on U.S. East Coast.'")

The Seascraper—a self-sufficient community of homes, offices, and recreational space—was designed with the intention of slowing urban sprawl, according to its designers.

The vessel's energy independence would come from underwater turbines powered by deep-sea currents as well as from a photovoltaic skin that could collect solar energy. The concave hull would collect rainwater and allow daylight to reach lower levels. Fresh water would come from treated and recycled rainwater via an onboard desalination plant.

This green machine would also help keep marine populations afloat, so to speak, with a buoyant base that serves as a reef and discharges fish food in the form of nutrients pumped from the deep sea, the U.S. design team says.

Floating Recycling Center

A larger-than-life lure, the Plastic Fish Tower would attract plastic instead of marine life in an effort to reduce the Great Pacific Garbage Patch, also known as the Eastern Pacific Garbage Patch.

Sprawling in the Pacific between California and Hawaii, this vast mass of mostly tiny bits of the world's plastic debris is twice the size of Texas. Ocean currents pick up millions of tons of discarded plastic and other trash, forming the garbage vortex.

The Plastic Fish Tower would collect and recycle the plastic flotsam with the help of a circular floating fence that creates a 1.2-mile (1-kilometer) circle around the sphere. Arms extending from the bottom of the sphere keep the fence in place. A mixed-use community, the Tower could accommodate residents on its outer rings and above-water sections, while a processing plant in the sphere's core would turn the trash into plastic fish-farm nets.

Specially designed boats would ferry people to and from the Fish Tower and would be "fueled by chemicals that will be collected from the processed plastics within the skyscraper in an as-of-yet-undiscovered method of chemical extraction," say the tower's South Korean designers.

Trash-filled "Oceanscraper"

Another solution to the Great Pacific Garbage Patch problem might come in the twisted shape of "oceanscrapers" built on underwater landfills, such as the Lady Landfill Skycrapers imagined above by a Serbian design team.

Trash would be collected at the bottoms of the towers and recycled in their cores. The undersea towers would support above-water islands hosting self-sufficient human settlements.

To keep the housing developments above from sinking, the Lady Landfill Skycrapers would take in or release ocean water to counteract the changing amounts of buoyant plastic trash in the hulls.

Plastics no longer needed for flotation would be converted into energy stored in massive batteries for charging island life, the designers say.

With only its stabilizing floating ring and transparent dome protruding above the sea, the Waterscraper is envisioned as a tubelike underwater residence and lab—all designed to withstand crushing water pressures.

Natural light would filter down from the dome as the Waterscraper drifts from one destination to the next. Beaches, restaurants, a marina, and a dive center would cater to luxury-apartment dwellers and hotel guests.

Concepts like the Waterscraper are being touted as potential solutions to the planet's urban population pressures.

According to the United Nations Department of Economic and Social Affairs, half of humanity currently calls an urban area home. And before we reach 2050, India's cities will grow by 497 million people, China's by 341 million, Nigeria's by 200 million, and the United States' by 103 million.

Oil Rig Reimagined

The Water Circles concept would convert old oil platforms into water-treatment plants that transform saltwater into fresh water. Remaining fossil fuel extraction infrastructure would be used to channel seawater into the floating desalination plant.

Spherical modules would distill saltwater and store fresh water bound for water-poor countries. The old oil rigs would also house researchers and sustain on-site food production, according to the South Korea-based design team.

Floating Cruise Ship Terminal

This 5-million-square-foot (490,000-square-meter) floating cruise-ship terminal could host three large vessels while providing passengers a novel offshore experience, complete with open-ocean hotel stays, shopping, and dining, according to designers.

An inner "harbor" would allow smaller vessels to dock and would provide natural light for the interior of the terminal. Ten percent of the roof would be covered in photovoltaic cells that harvest solar power, according to Dutch architect Koen Olthuis of Waterstudio.NL.

The terminal is just a vision now, but Olthuis's firm, which is committed to buildings that both adapt to and combat the challenges presented by climate change and sea level rise, has made other floating fantasies come to life.

Waterstudio.NL, based in the Netherlands, has worked on a floating city near The Hague and has started projects in the Maldives, China, and the United Arab Emirates.

The Citadel

Scheduled for completion in 2014, the Citadel could be Europe's first floating apartment building, according to architect Koen Olthuis of Waterstudio.NL. The 60-unit complex is to be built in the Dutch city of Westland, near The Hague, and is meant to protect people from flooding in a country that sits, to a large degree, below sea level.

Holland is home to more than 3,500 inland depressions, which can fill with water when it rains, when tides come in, or as seas rise overall. These so-called polders are often drained by pumps to protect residents.

Floating single-family homes are not uncommon in this soggy country, but the Citadel—to be built on a flooded polder—will be the first high-density floating residential development. The complex's floating concrete foundation will be connected to higher ground via a floating road.

Olthuis predicts the Citadel—and its five planned neighbors—will consume 25 percent less energy over its life span than a conventional building.

Green Sea Star

Slated to open in 2014, the Greenstar is to be a floating hotel and conference center off the Maldives in the Indian Ocean. The island nation is the world's lowest-lying country, making it among the most threatened by anticipated climate change-induced sea level rise.

Designed by Waterstudio.NL to blend in with its ocean surroundings, the Greenstar will have room for 800 overnight guests and 2,000 conference attendees.

Intended to be highly efficient, the development's small environmental footprint is a tribute to the country's determination to fight global warming, according to Waterstudio.NL architects. Appropriately enough, organizers intend the Greenstar to be the number one meeting place for global climate change discussions.

Float House

Making the most of waterfront views, Dutch architect Koen Olthuis designed this floating single-family water villa in Amsterdam to maximize privacy and versatility.

Completed in 2008, the building's bedrooms and bathroom are on the first floor, partially below water. Large sliding doors on the top floor open to a wooden deck, offering the illusion of being on a boat.


I honestly can't pick a favorite but I have narrowed it down to the Floating Recycling Center and the Waterscraper but I think they are all great ideas nonetheless.

Do any of you have a favorite?

And if so, why?

Please feel free to add any of your own ideas as well, this could be very interesting.

Great thread!

But floating on water is only one of the possibilities. Structures in the sky that hold "passengers" and could be developed into floating cities has been theorized as well.

Star and Flag OP!

Thanks for sharing this article. My favourite one is the Oil Rig. If I were to create an idea I would like to invent an amusement park that floats on the ocean. It sounds impossible but it's nice to dream sometimes.

I have always been interested in floating cities in the sky and similar ideas. The possibilities are endless especially if we were to master the technology that could keep these floating sky cities in the air. Perhaps there is technology that exists but I'm just unaware about it

An amusement park on water would be a great idea

In fact, they could probably build one on Green Sea Star that was included in my OP. That would make one heck of an amusement park.

Sky cities on Venus would be pretty awesome. About 50km up in the Venusian atmosphere the temperature and pressure is fine for humans, although you'd need an oxygen mask to keep you alive.

The dense atmosphere would also make it easier to float big things like cities. Could they float so high as 50 km? I have no idea. It would be so awesome though.

Great idea

Perhaps they could have the floating city self contained so the gas mask isn't necessary. But if possible I would certainly stroll through the Venus atmosphere with a gas mask at 50 km altitude.

Nice images and link. Very interesting concepts. Someone should make a movie for the imagination to prosper even further and possibly a prorotype in the making?

A movie and prototype would be a great idea as well.

I would have troubles though with my limited imagination so we would have to leave it up to the pros.

As you guys are interested ,I suggest you study Pykrete. Pykrete and similiar materials have been considered several times but due to lack of insulation it was not possible. But with aerogels its very feasible and possible to build floating ocean cities .Pykrete's main ingredient is water and sawdust.

venus atmosphere is 60% heavier than earth atmosphere at 1 bar. at 50 km ,venusian atmosphere pressure is 1 bar and at ground level it 93 bar.

There are two ideas:

1)buoyancy using vacuum/hydrogen/helium(saturn/uranus/neptune).(normal earth air will do for venus as earth air is less dense than carbon dioxide)
2)use of anti-gravity(its said that altantis,hyperborea use to use this)

Thanks for sharing the ideas.

Do you think it could really work?

Yep. Thats what I meant that wish Hollywood (James Cameron) can come up with one.

The mixture can be moulded into any shape and frozen, and it will be extremely tough and durable, as long as it is kept at or below freezing.
As per the wiki, this is still under investigation and studies.

in my opinon ,both can work.But it will be easier to use the anti gravity pathway as an existing city could be transformed into a flying one via means of anti gravity generator.

the buoyancy cities would need considerable amounts of aerogels which would be expensive.

Buoyancy city:
The volume of hydrogen gas heated to the temperature of a standard Earth environment required to lift a metric ton of mass at the one bar level in one of the gas giants at Solsys is as follows:
Jupiter: 14000 m3
Saturn: 9330 m3
Uranus: 3030 m3
Neptune: 2920 m3

Disk Radius

50 m 100 m 500m 1 km 5 km 10 km
Jupiter 419 m 665 m 1940 m 3.08 km 9.02 km 14.3 km
Saturn 366 m 580 m 1700 m 2.70 km 7.98 km 12.5 km
Uranus 251 m 399 m 1170 m 1.85 km 5.42 km 8.60 km
Neptune 248 m 394 m 1150 m 1.83 km 5.35 km 8.49 km

wiki is utter crap. Maybe you consider the insulation capability of aerogels to insulate pykrete. Also in space especially beyond Jupiter,temperatures are in minus.Which means that Pykrete can be used for o neill cylinders without insulation.

When we run out of land to develop on, sea is the next logical place to explore for sure, interesting images, thanks for sharing.

it does make you dream about how can be our futur
green non poluting cities where everyone lives egualy with technologies beyond the wildest dreams

These cities will exist in the near futur
