Why Floating Cities are Becoming a Thing
As the size of the big urban bubbles grows, more and more coastal locations throughout the world are being flooded. By 2050, 800 million people from 570 cities may be forced to relocate. Instead of relocating to individuals who work in our cities, someone has proposed establishing an island metropolis in the middle of the ocean. But is this simply a fantasy, or will some of these technology make their way back to dry land?
By 2050, 90% of the world’s main cities will be hit by a wave of climate change. Some cities have already made steps to combat this, such as Shanghai, which will see a two-foot rise in sea level by 2050. The Chinese metropolis is already ringed by 520 kilometers of protective ceilings to keep itself dry. There’s also the HafenCity flood-proof neighborhood pumper, which features waterproof structures on mounds and a ground-level gate system.
Lake City and Stockholm were moist gardens hail storms in the event of a flood or the hammer. In 2012, Hurricane Sandy wreaked havoc on Manhattan. It left 500,000 people without power. The dry land project, designed by Bjarke Ingels’ Big, will protect York City’s financial district from future hurricane-driven floods. With a mix of climate security and recreational opportunities. This seven-mile water-repellent ribbon includes green parks, bicycle shelters, and boards that serve as seawalls and provide a long-term dry run.
According to the Center for Climate Integrity, the United States will have spent $400 billion by 2040 trying to safeguard coastal cities from rising sea levels. And that appears to be an unsustainable premise. But Ingle’s creative mind appears to have a solution for that as well. Aside from building efficient seawalls, the Danish architect is also responsible for the design of Ocean City. The UN has backed a project to build a floating city, and this isn’t the only plane that will float. Well, there has been some exciting movement toward making the floating dream a reality, which I’ll discuss in a moment. Cities have a number of difficulties. New Orleans might be a good place to take a seat. It fulfils all of the requirements. Some parts of the city are eroding at a rate of two inches per year, and by 2100, they may be underwater.
In addition, the Crescent City is situated on the Mississippi River Delta, with some parts reaching nearly ten feet above sea level. Not to mention the threat of storm surges. It’s easy to see why some engineers proposed seasteading as a way to save millions of dollars. What exactly is seasteading, though?
In a nutshell, it’s your permanent residence on the other side of the world. In other words, it’s a system rather than a homestead. That’s logical. If you think about it, anti-aircraft stations, cargo ships, and even oil are all examples of seasteading floating around in the water. So, can we just build an entire city on a shipyard, like New Orleans? There are obviously some difficulties with this, like as the city’s weight, which would force the shipyard hole 300 feet underground; moreover, the size of the shipyard in New Orleans would be larger than the combined size of the world’s three largest shipyards. The most difficult challenge, though, is weight. Their impact on the vast shipyard, in reality, would result in structural failure. So, what are our options?
We could design a flexible system that essentially surfaces the waves, which would entail interconnecting much smaller components into a larger framework. Rather of relying on a single huge wealthy platform, New Orleans may learn from the Netherlands. Water studio and other architects in Amsterdam have previously created a floating village with a population of 100 people divided across 46 dwellings in order to stay afloat. Apart from providing shelter, the city should be able to support itself so that people can live off the grid, similar to living on a long-term cushion. Aside from wind turbines and solar panels, it’s the ocean, of course, with fascinating technology.
Ocean thermal energy conversion, or OTech, is one of the most promising technologies because it makes use of the natural temperature gradient between the surface and lower depths of the ocean, which may be turned into electrical energy and used in a closed loop. The OTech method for warmer surface water vaporizes a low boiling point fluid such as Steam, which then travels through pipelines until it reaches a turbine, which is connected to the generator. Finish the loop. Colder ocean waters emerge from the depths to breathe and use the Harmonic vapor. The fascinating part is that the leftover cooling water may be used to grow food in aquaculture facilities, such as fish and algae. There’s also an open loop. Instead of ammonia, the OTech plant would vaporize a circle, lowering the amount of ammonia remaining when it condenses back into the form you’re left with dissolved in water overall, and the OTech facility might potentially generate clean energy and food.
It doesn’t matter which way you slice it, increasing sea levels and catastrophic weather events are a very significant threat to humanity’s survival. Those who live near the seaside will, without a doubt, be among the first to suffer the consequences. If climate change continues at its current rate of acceleration, we could all find ourselves knee-deep in saltwater in a short period of time. That is precisely why the architecture company Bjarke Ingels Group (BIG) has been given the formal go-ahead to begin construction on its proposed Oceanix floating city.
South Korea will soon be home to the world’s first floating metropolis, which will help the country deal with the problem of flooding caused by increasing sea levels. It is a collaborative endeavor between the United Nations Human Settlement Programme (UN-Habitat) and OCEANIX to build a floating city. The metropolis, which will be built off the coast of Busan in South Korea, is expected to be completed by 2025, according to plans.
The floating metropolis, which will be developed off the coast of the city of Busan and backed by the United Nations, will be a “flood-proof infrastructure” composed of multiple man-made islands that will all rise with the tide to eliminate the threat of flooding.
The self-sufficient city will generate power from solar panels atop buildings, grow its own food and produce its own fresh water, and ferry residents between islands in futuristic boat pods, according to the plan.
It will also be able to endure natural calamities such as floods, tsunamis, and Category 5 hurricanes due to the fact that it’s floating platforms will be moored to the sea floor.
‘Historic agreement’ signed between Busan Metropolitan Metropolis of the Republic of Korea, UN-Habitat, and New York architects Oceanix will see the construction of a floating city, which is expected to cost $200 million (£150 million), get underway soon.
It is still unclear whether or not residents will be required to pay a fee to live there, or how much the rent would be.
While the practical results of BIG’s Oceanix floating city have yet to be seen, the self-sustaining aspect of the project encompasses everything from sourcing its own food through scallops, kelp, and the like to producing its own energy and fresh water thanks to a fully-integrated, closed-loop system and, most importantly, creating zero waste. In addition, the modular architecture will be able to survive any natural calamity that may arise in the future. Let’s just hope Mother Nature doesn’t come up with anything too inventive between now and the year 2025.
“We believe that humanity can coexist peacefully with life below the surface of the ocean. It is possible to live on water while allowing nature to continue to grow beneath us thanks to advancements in technology. Oceanix is pioneering a new industry with blue technologies that meet humanity’s shelter, energy, water, and food demands while without destroying marine ecosystems.” Oceanix is a leading provider of blue technologies.
The United Nations Development Programme (UN-Habitat) is preparing to collect and analyses data from the Oceanix floating city prototype. It has been reported by the Robb Report that Project Oceanix is currently engaged in negotiations with ten additional governments outside of South Korea about similar projects. In other words, if all goes according to plan, it might very well serve as a model for a solution to this particular component of climate change.
