Waterstudio’s floating sea wall harvests blue energy from crashing water

By Tafline Laylin

December.2015

 

Certain world leaders might be dragging their feet on addressing climate change, but in the meantime, Koen Olthuis and the rest of the Waterstudio crew are working on solutions that we can use today. The Blue energy floating sea wall is a floating breakwater that doubles as an energy generator. Called The Parthenon, the floating breakwater not only stems the crash of water pushing into a harbor, but harvests the tremendous energy a wall of water like that can generate.

Waterstudio used the Hudson River to illustrate their new design’s function. “In a harbour on the Hudson river in New York the wave conditions are so strong that a sea wall must protect its boats. The strong current in the river is constantly attacking it and water is pushing itself against and through the fixed wall, which results in more corrosion of the sea wall every year.”

The floating sea wall acts as a permeable breakwater that converts the wave power into electrical energy while reducing the waves’ impact on the harbor at the same time. “The floating breakwater lives with the force of the river instead of fighting it,” they told Inhabitat in an email.

The columns of the sea wall are comprised of 3-foot cylinders that rotate – both clockwise and counter clockwise – at low speed. The energy created by this rotation is then captured in a concrete box inside the floating platform. The cylinders are filled with water to give the structure flexibility without affecting in any way the efficacy of the wall in reducing the wave’s impact on the harbor. The whole thing is then anchored to the riverbed, and the top can double as an urban green space or boulevard.

“The Parthenon blue energy sea wall resembles the column structure of the famous ancient temple in Greece,” according to Waterstudio, “but divers see it as a part of the sunken city of Atlantis.”

The Floating Dutchman

THE FLOATING DUTCHMAN

In the tradition of his water-taming nation, Dutchman Koen Olthuis designs floating islands to dwell and live on – not least because climate change calls for new solutions in architecture.

A vacation doesn’t get more wonderful than this: a white sandy beach, a green-blue, glistening sea and an exotic underwater world to thrill any snorkeling enthusiast. All you have to do to explore it is jump into the Indian Ocean from your personal jetty, because the elegant vacation villa where you’re staying is floating on the water. In a Maldivian lagoon, this dream is currently becoming a reality as the construction of 185 floating vacation homes is currently underway. They’re arranged in the shape of a giant flower on the water. Hence the name of the project: Ocean Flower.

It was designed by Koen Olthuis, a Dutch architect who is considered a pioneer of what is called Aqua Architecture: “I build exclusively on the water,” says the 44-year-old with a strawberry-blonde mop of curly hair. His buildings are made to withstand floods and climate change because everything Olthuis designs can adapt to the level of the sea. It is not by accident that his office in Rijswijk near The Hague bears the name waterstudio.nl.

Bracing for climate change, without leaving a trace

In order to make such bold projects as the Ocean Flower a reality, Olthuis partnered with a fellow Dutchman, project developer Paul van de Camp, to found the company Dutch Docklands. It buys water properties all over the world to use them as building sites. This opens up completely new perspectives – not only for densely populated cities or countries where building sites are in short supply and hence, expensive: “It also helps residents protect themselves from the consequences of climate change.”

There is a reason Dutch Docklands launched its first project in the Maldives. It’s not just to cater to the recreational interests of spoiled tourists: The 300,000 inhabitants of the island nation will soon literally be up to their necks in water, because 80 percent of the Maldives are located barely a metre above sea level. The government had already announced plans to buy to land elsewhere in order to survive. Until Olthuis and van de Camp assured them that this was quite unnecessary: “We made the President of the Maldives understand that climate refugees can be pioneers of climate management,” said Olthuis. They understood immediately.

The Ocean Flower is just the beginning: Four more lagoons with floating vacation lodges are to follow, as well as a floating conference centre and one of the world’s most spectacular golf courses that will spread over several man-made islands to be connected by underwater glass tunnels.

And all this can be done without leaving a trace in nature or inflicting any damage, for Dutch Docklands is committed to what it calls the scarless approach: “Our units can float anywhere on the water for 200 years, yet if the area is needed for some other purpose, they can just be hauled away,” Olthuis explains. They will be gone without a trace.

The Dutch know how to live with the water

It isn’t surprising that the pioneers of Aqua Architecture are Dutch: Like no other people, the nation at the mouth of the Rhine River has spent centuries learning to tame the water or to keep it in check with dikes, dams and levees. As the proverb goes: “God created the world – and the Dutch the Netherlands.”

Whether it is in New Orleans or in Bangladesh: The expertise of Dutch hydraulic engineers and architects is in high demand throughout the world – today more so than ever, thanks to climate change, which brings swelling rivers, rising sea levels and more catastrophic floods around the globe.

The Dutch have long recognized that building ever higher dams won’t be enough. Therefore, the former nemesis is instead given more space: Polders are being flooded, retention basins are being built, tributaries being carved out and filled-up canals dug free again.

The old seafaring nation now has even less residential land available. Yet the Dutch discovered that the flooded polders and artificial water basins offer more benefits than just a controlled channeling of excess water.

Trend and challenge of generation climate change

As a consequence, aqua living has since become a trend in the Netherlands; all over the country, people reside in what is called waterwoningen. Their foundation consists of a concrete tub filled with Styrofoam, which is considered unsinkable. To keep them in place, they are moored to poles with rings so they can easily adapt to rising sea levels. Electricity and water lines are connected via hoses and cables.

Olthuis has designed countless waterwoningen: transparent villas sitting elegantly on the water, such as in Aalsmeer, Zwolle, Leiden or Amsterdam, which received an entire floating neighborhood in 2012, the steigereiland. In Antwerp, Olthuis designed a floating boulevard on the Scheldt, in Paris he created a restaurant on the Seine. And in a polder between The Hague and Delft, he wants to build de Citadel, Europe’s first floating apartment complex on a foundation of 140 by 90 metres. “Technologically speaking, all of this is easy to do,” he stresses.

The technology developed and patented by Olthuis virtually eliminates size limits on foundations for waterwoningen. In other words, the foundation can be a platform large enough to accommodate entire blocks of houses, complete with yards and parking garages: “The larger an object, the more stable it is on the water,” the architect explains.

Olthuis is therefore convinced: The city of the future consists of floating platforms that can be moved around like floes of ice. “It will evolve one step at a time,” the bold Dutchman predicts: The next fifteen years will see churches, schools and sports fields move out onto the water, then in 50 years, we will have platforms as large as 200 by 200 metres, with houses, roads and parks – until a century from now, the city of the future will be a reality: a flexible delta-metropolis of floating elements. For Olthuis, this new type of urban design, this new flexibility is “the great challenge for the architects of the climate change generation.”

1st Scientific paper on researching wetslums was published

Slum Upgrading: Assessing the Importance of Location A plea for a spatial approach as an integral component; view online (free till Nov 1st)

Abstract

The world population is growing rapidly and much of that growth is happening in urban areas. In developing countries, this process is often accompanied by the formation and expansion of slums. A variety of slum upgrading projects have been implemented to improve the living conditions of slum dwellers however a wide study to investigate the objectives of slum upgrading projects highlighted that environmental features were of low priority compared to basic services and infrastructure. The paper deduces this to be a result of the dominance of UN’s household-based definition of slums which lacks emphasis on the locational aspects. An aerial analysis of slums located near waterbodies emphasised the slums’ dynamic nature brought about by location and therefore the importance of location itself. Taking cue from this, the paper recommends upgrading projects to be more location-specific that offer flexible yet customised solutions that build upon local knowledge to account for the dynamic and diverse nature of slums. Another inference from the study was that for various reasons – one of which is hazardous location – slums are perceived to be temporary and as a result, there is low incentive to invest in slums. Such a perception prohibits slum upgrading and pushes them into a negative spiral. Concluding that slums are, however, permanent features in the urban landscape, the paper recommends a change in perception and urges practitioners to accept this permanent nature of slums. The focus and findings of this paper are relevant in context of the Habitat III Conference in 2016 which has as its focus the ‘New Urban Agenda’ that recognises the ever-changing dynamics of human civilization and aims to bring together diverse urban actors to review urban and housing policies.

Podcast: Maldives’ Floating City?

The Seasteading Institute, Joe Quirk, Nov 2015

Interview of Joe Quirk from the Seasteading Institute with Koen Olthuis about  Maldives’ floating cities.

Podcast: Maldives’ Floating City? Koen Olthuis of Waterstudio

Podcast: Play in new window

What if a nation sinking below sea level became the innovation hub for floating cities?
What if you could float the infrastructure of Holland to the slums of Bangladesh?
What if the future of floating cities is in 3D printed technology?

Dutch architect Koen Olthuis is the co-author of Float! Building on Water to Combat Urban Congestion and Climate Change with David Keuning. Koen founded Waterstudio which designs many components of floating cities, including schools, golf courses, hotels, and even stadiums, and he co-founded Dutch Docklands which plans gorgeous projects for the Maldives.  In 2007, Koen was chosen at Time Magazine‘s “most influential people of the year,” and the French magazine Terra Eco chose Koen in 2011 as one of the 100 greenest persons who will change the the world.

Koen Olthuis initiated a project to transform shipping containers into Floating City Apps to upgrade living conditions in coastal slums by providing “plug-and-play” schools, kitchens, health centers, internet cafes, and water purification units.

Should seasteads establish political independence first, and then change the world? Or should floating cities set humanitarian examples, win hearts and minds, and then seek independence? Koen and I discuss the strategies and agree to partner on a shared goal.

I hope you enjoy this discussion as much as I did. And if you subscribe to podcasts on iTunes, you can find this podcast and all of our other podcasts on our iTunes page.

Why Blue is Better

Annelie Rozeboom
Hi Europe
October.2015

 

Architect Koen Olthuis draws on a roll of paper while explaining why we should be building our cities on the water and how he is planning to help the poor with his ideas. “As an architect, you can design towers, but every child can do that in their Minecraft game. Plus none of the towers we build now will be there in 300 years’ time. What I want to leave behind at the end of my career are concepts and ideas, the main idea is that we need to push our cities unto the water.”
Green is good, blue is better is the motto of this Dutch architect. “Our cities don’t change fast enough. We build houses and building and expect them to be used for ever, but our society changes every ten years. If parts of our cities float, we are much more flexible. The center of Amsterdam will always be the same, but the neighborhoods around it change all the time. If buildings float, you can just pull them away and put them somewhere else,” Olthuis told Hi-Europe.

Working with the Water

One-half of the Netherlands is flood-prone and about one-quarter is below sea level, so it’s no wonder the Dutch spend their time developing ways to incorporate water into their style of living. The philosophy is shifting from fighting the water to living with it, or rather, on it. Instead of trying to claw back more land from the sea, developers are exploring the cost-efficiency of building homes that rise and fall with the tides. “We need to start working with the water in a more intelligent way,” Olthuis says.

This relatively new amphibious architecture is attracting interest from around the world, with floating and amphibious homes and schools now being designed for flood plains everywhere. Amphibious architecture is for both dry and wet conditions, so the houses stay dry and on the ground during normal times and then when the water arrives, they can float up.

Waterstudio

Olthuis wants to do much more than build a few villas. His architectural bureau Waterstudio.NL has designed complete apartment complexes, which could accommodate hundreds of people. And that is just one project. There is also a 33-meter-tall trees that can float. “Our cities have become sick environments. Green has been pushed away, but bees and other insects need quiet places. Our sea tree is like a cut-up park, which floats at a safe distance from the shore. Nature will take over on the platform and create its own ecosystem.”

Olthuis is also planning to help people in the slums of the world, which are often located on flood plains. “Worldwide you see that the most vulnerable people are being pushed into the water,” he says. This coming month he will send a floating school to Dakar – it’s a container that floats on empty plastic bottles. “The way to upgrade a slum is by installing facilities like schools and internet cafés, or easily movable small buildings that slum entrepreneurs can use. We have designed a kind of toolbox, which have 20 functions inside. This way, the entrepreneurs can choose what it is they need.”
Olthuis exports his concepts all around the globe, including to the flood zones of Hainan Island. “They have land there that they can’t use, but they will if they take our technology.” He also sells floating islands to Dubai. “Making artificial islands out of sand doesn’t work. In Dubai they built some, but they are too far away from the coast, and there is no electricity or drinking water. We are now going to put floating islands in between.”

Fight Against the Sea

The Dutch are famous for their age-old fight against the sea, and they have the best flood management technologies in the world. In the beginning, the people in this low country put their homes on artificial hills called terpen, but they soon started building dikes. Popular in the middle ages were wierdijken, earth dikes with a protective layer of seaweed. Later dikes had a vertical screen of timbers backed by an earth bank, but these were replaced by stones after the timber was eaten by shipworms. When the polder windmill was invented in the 15th century, it meant that land could also be drained.

The dikes around the rivers were maintained by the famers who lived next to them. Special water board directors would come to check every three years. This changed radically after a devastating North Sea flood in 1953, which resulted in 1,800 deaths. The government adopted a “never again” attitude, and built dams all around the country, guarding all main river estuaries and sea inlets. According to computer simulations, today’s defenses in the Netherlands are supposed to withstand the kind of flood so severe that it would occur only once in 10,000 years.
“We have pretty much won the fight against the sea,” architect Olthuis says. “The problem now is rainwater. Holland has 3500 low-lying polders enclosed by dykes that function as sponges – they soak up excessive rain water. However, more and more of this land is now used for housing. These are ideal places to build amphibious houses.”

Rising Sea Levels

Dutch scientists predict a rise in sea levels of up to 110cm by the year 2100. “We can make the dikes higher, that’s not a problem at all. Technically, all that is possible. The problem with a high dike is that when it breaks, more water will come in,” he says.

There is also growing pressure on existing land. The Dutch government estimates that 500,000 new homes will be needed in the next two decades. Most of the land suitable for conventional building has already been used up, so Dutch architects are encouraged to experiment with new solutions. “The palace in the center of Amsterdam was built on 13.654 wooden poles. It’s the densest forest in the Netherlands. There was real innovation in those times. We are built on places where there shouldn’t be land at all. It’s not about giving up, it’s about continuing to grow,” says Olthuis.
