Engineers Propose Lily Pad-Like Floating Cities

Zothecula writes "The idea of going offshore to satisfy our renewable energy needs isn't new, but the grand vision of Japan's Shimizu Corporation goes way beyond harnessing green energy at sea for use in cities on Terra firma — it takes the whole city along for the ride. The company, along with the Super Collaborative Graduate School and Nomura Securities, is researching the technical issues involved in constructing its Green Float concept — a self-sufficient, carbon-negative floating city that would reside in the Equatorial Pacific Ocean."

    As an engineer, I like to think about screwy problems from time to time myself, and have even devoted a little time to the concept of floating housing and infrastructure;

    The problems with building in the ocean are immense:

    1) The ocean is not "smooth and placid", even on a calm day. The cyclical action of small waves lapping against, and rolling under the surfaces of any floating structure causes abrasive damage to those surfaces. This is worsened by "Cavitation", when the water is moving quickly, (basically dissolved gases in the water get turned into little erosive bubbles as the water gets 'torn' by small surface imperfections as it flows over it) such as when there is high wind. This means that any non-self-regenerating surface (pretty much anything other than living tissue of some sort, like coral) is going to end up as nanoparticulate goo in one of the ocean's gyres.

    2) Bouyancy is a major, non-trivial issue. Bouyancy will degrade over time as organic "Cling-ons" stick to the water-exposed surfaces. (In the ocean, this includes coral buds, kelp fronds, barnacles, and friends.) Additionally, "uneven" construction above on top of the "plate" will cause listing of the bouyant building surface. You would need to displace an obscene amount of water to hold up a traditional wood-frame house. (I know, I did calculations for it!) Even more if you intend to have any kind of yard or agricultural system running, since dirt weighs MORE than water. (meaning you must displace MORE water than the same volume of soil.)

    3) Strapping discrete units together causes mechanical stresses at the joints, as the whole under-surfaces of the floating plates act as levers, applying blunt prying force on the joins. You can alleviate this somewhat by using a cantilouvered (sp? whatever.) design, but then you end up with mechanical wear as the joints rub from the undulating motion of the connected platforms.

    All of these problems are major issues for "Fair weather" construction-- The implications of weathering a hurricane or coastal tsunami wave (remote ocean, where the water is deep, Tsunami are not a major factor.) impose whole orders of magnitude greater difficulties.

    Based on some observations I have made on water turbulence, any "Floating city" would be better off about 6 meters under the water's surface, than it would be at the surface. Most ordinary wind driven water flow is greatly slowed and stabilized by the time it reaches that depth, reducing cavitational damage on the outer skin of the complex. Bouancy is more easily controlled with a ballast system, and due to the subdued wave-action at that depth, the mechanical forces between modules is greatly reduced.

    Such a complex could be constructed between what would essentially be "deep ocean oil platforms", but without the oil pipelines. These would function as pylons to help constrain the floating complex, and provide the infrastructure to enter and leave the complex at the surface.

    Building UNDER the water has other problems though-- Namely, risk of flooding, people getting trapped in airlocks, and the whole ball of wax of air, air quality, and atmospheric reprocessing/exchange. (Sad truth-- pumping air is expensive.) At such a shallow depth (basically 18 feet or so) there is little risk of developing nitrogen narcosis, but there would still be psychological effects of living in a tin-can.

    Pretty much, the difficulties in constructing and maintaining a general purpose, habitable structure that is underwater is why there are so few of them, and none of them are 'large scale' construction projects.

      Nitrogen narcosis isn't an issue - or the narcotic properties of other gases breathed at pressure. Not at 6 meters.

      One physiological issue that would have to be dealt with is DCI (decompression illness). Spending a lot of time underwater, even at shallow depths, is going to require a metric asston of decompression when you return to the surface. Decompression theory isn't an exact science - and AFAIK, there isn't a lot of empirical data regarding long-term exposure to higher than atmospheric PPN2.

      Being tethered to the support "pylons", if you had a good balast system installed you might not need to pressurize at that shallow of a depth, since that pressure is well within the bounds of current and conventional construction materials to endure. (Several hundred PSI at worst.)

      You would "weigh down" the structure with dirt, and use a pumped ballast system to control the bouancy of the complex. There would be an emergency pressurization system to cause rapid ascent in the event of a major mechanical disaster (interconnects between modules breaks, balast system experiences extreme fault, etc--) which would pressurize individual modules, and make them self-bouyant in order to prevent having people in them sink to davy jone's locker, but this system would only activate in the "OMG WE'RE ALL GONNA DIE! AHHH!" type circumstances.

      Basically, the idea is to have the connected modules have "neutral bouancy" at that depth, by having static ballast to overcome their water displacement. With that achieved, direct airway access to the surface is possible, as long as the skin is made of a material strong enough to endure the crushing weight of the water around it.

      As you go deeper down, the pressure difference is too high for materials science to keep 1 atm pressure, so they have to "reinforce" the skin by pressurizing the interior; this is when you start having decompression issues and the like.

      Even then, there are effective maximum depths at which ordinary atmospheric gas becomes a problem, but you already seem to have a full working knowledge of that problem.

      At the extreme, the pressure inside the vessel (needed to keep it from crushing up like a soda can) is itself deleterious to the health of the occupants, causing biological disorders in and of itself. (the pressure starts mucking up with cellular metabolism and various vital processes, simply because of the different chemical properties that the body's fluids take on in such conditions.)

      As such, "Living on the deep ocean floor" is probably never going to happen.

No significant group of human beings will pay thousands of dollars per square foot to live on open ocean - but those prices are just about right for certain crowded coastal cities like New York, San Francisco, et cetera. If this project were built as an expansion to an existing city, it would have a shot at being economically feasible. If it were built anywhere else on Earth, there's no way. The overwhelming majority of people will not choose to spend exorbitant amounts of money to live in economically isolated bubbles - there are a few counterexamples (eg certain kinds of suburbs), but they mostly serve as disastrous examples of how NOT to spend money developing cities. In practice, architects who overdevelop undervalued land lose big time.

    *The Norwegian Epic is currently the largest cruise ship in the world. It cost about a billion dollars to commission, and is about 130,000 square feet across. It has 19 decks, so generously assuming each deck provides a full 130,000 square feet of habitable space, it cost about $5000/square foot.

    Second opinion: Scale it down. Bigger is not always better. A project of this size (eg. a 1.5km high tower in the middle of a 3km diameter floating steel bowl) would require tens of billions of dollars in funding and decades of planning and construction. If funding of the project is lost at any point during construction, you're left with an enormous rotting steel skeleton that has no practical economic value. (Similar example: "The World" in Dubai. A super-expensive man-made archipelago that lost funding during the 2009 financial crisis and is now just a $14 billion testament to the dangers of mixing cocaine with urban planning.)

    Third opinion: Scale it down. The only thing worse than living in a giant, featureless box is living in a stack of giant, featureless boxes.

    Fourth opinion: I love urban agriculture. I love greenhouses. I love arcologies. But this is stupid. Rather than spending billions of dollars on a floating experiment (that I can tell you right now is doomed to failure), they could spend some of that money proving that multi-use residential/commercial/agricultural/recreational skyscrapers are an economically viable model for development. It would only cost about a few hundred million dollars at most - peanuts compared to this proposal - to buy several existing skyscrapers, gang them together with skyways/aerial walkways, and convert their top floors into open-air parks, greenhouses, et cetera. If the resulting development could be sold or leased profitably, and could function efficiently and with good livability, it would validate many ideas and would encourage future development along these lines.

      Clearly you've never read of what happens when oil really goes away. To do that, set your clock back to wartime in Europe. It wasn't that conservation, panic, or anything else. It was coal gasification city. Everything was powered by wood and coal. There is a hell of a lot of coal (now some people say it's peaked but that just ain't so). Coal can be converted into diesel, gas, plastic. If the Nazi's produced millions of gallons of aviation fuel from coal while their country was under attack by half the world, the United States can produce a lot more in peace time. In fact, 240,000 barrels a day are produced world wide, right here and now. However, coal is really just the start of this process - biomass goes in with no modification. If you have large quantities of hydrogen (which you have if you have a lot of electricity) and CO2 (which you can capture with a high school science experiment scaled up), you have the input of the process. So anything that produces electricity produces oil.

      Now, you're probably saying, ooohhh that's a technological fix that can't work. Here's the issue. Every time we're about to run out of something, we find a technical fix. When we ran out of wood, we found coal. When we ran out of whale oil, we found ground oil. When we started to feel the first hits of oil depletion, we found natural gas. We also found nuclear but many people don't want to talk about that. Imagine our society today trying to run on whale oil. It just would not happen. You'd be lucky if you got a week of power out of whale oil.

By necessity I mean things like the land becomes undesirable from crowding, pollution, corruption, war, or flooding. Then people will move out to sea to be subsistence fishers, pirates (making a living by stealing from those that have stuff, which can only last so long as there are people with stuff worth stealing), or perhaps some other unforeseen profession. The move out to sea from necessity will not be pleasant, and is not likely to be "green" since people in survival mode are more concerned about today than tomorrow.

    If people are going to move out to sea for profit then there needs to be a product. We already see ships that can create a comfortable environment for months without a need to return to shore. When they return to shore they do so for trade for things that can be found more easily at sea for things that can be found more easily on land. If there is desire to create a "city" out in the sea then one must find a way to economically produce more things that can currently only be profitably produced on land.

    One reason that all current ships need to return to shore is for fuel. This is one key aspect in my mind for sustainable living at sea. Nuclear powered ships can stay at sea for fifty years. If there is a way to draw nuclear fuel from the sea then that need can be fulfilled without returning to shore. The ocean is full of uranium and thorium dissolved in the water as salts. If someone can figure out a profitable way to extract those fissile materials from the water then the ships can fill their own reactors and perhaps have some extra to sell to people on land.

    Nuclear power is fine for very large ships but smaller ships will need diesel fuel. This can be drilled from the seabed or synthesized from nuclear power. If we ever figure out fusion power then the ocean can be mined for fusion fuels like hydrogen, lithium, and boron.

    The other reason people need to return to shore is for food. There is plenty of fish out there, and we have plenty of experience in extracting fish from the sea. People will need water, but we also have plenty of experience in making sea water fit to drink. When it comes to things like grains, fruits, and vegetables that will have to be traded for with land based economies or we will have to develop the technology to grow it at sea. If we have come to the point where we can economically produce food and energy then it is a small step to produce cotton, wool, and other materials for clothing.

    Once we have developed the basics to provide food, water, shelter, heat, light, and such we can concern ourselves with more luxurious items. Cruise ships built only to entertain people are already in existence. The only difference now is that with the infrastructure of ships producing food and energy then the ship will not need to go to any port. People will wish to have the means to get from ship to shore quickly so there might be a floating airport in this developing flotilla. Then people on these ships might have a desire for protein other than fish. We might see floating dairy farms and chicken coups for fresh milk, eggs, chicken, and beef.

    I don't think that a floating city will ever be developed until all the technologies have been proven on other ships for many years. I think that a sustainable floating economy will just happen in time. It will start with fishing boats, oil rigs, and cruise ships looking for ways to cut down on costs and improve living conditions.

Another analogy - we are needlessly throwing in the garbage bin packs food that contains say 1000 calories per pack, but we build special trash bin (using LOTS of resources for R&D) which converts into useful energy small portion of the energy released by the impact between the food and the container. WOW, we are getting back 20 calories, otherwise lost in heat! We are going green! Youhoooo!

    I am speechless by all this. Such stupidity surely will be edited by natural selection. Can't wait...

    It'd be amazing how much more trivial something like this would be if we had a theoretically perfectly rigid/strong material that could withstand near-infinite forces, and was super cheap to produce.

    That and unlimited energy such as fusion would propel us into a real space age. Sigh...
