| 7 billion humans | only 4 billion can live in normal land cities | the 5 billion others need to be accomodated on the oceans (or in outer space) | what is more feasible? |

The situation: there are 7 billion humans on the planet already. To get a equilibrium with nature having about 3-4 billion in land based cities is the “planetary sustainability maximum” without trigger species mass extinction (status back in 1970). The at least 5 billion “rest that does not fit and can not be accomodated on land” needs to solve their housing needs in the only space that is left and available – the oceans - all this upcomming in the next 30 years. ( 10-11 billion population expected).

This creates a need for a “marine construction business” of gargantuan scale…(around 200 billion real estate squaremeters to build in 30 years) conservative numbers.

What needs to be done to achieve that the people who invested 7,2 billion USD in the structure (right) start to invest into the POTENTIAL of Seasteading…

Marine construction business. 5 billion humans will need real estate squaremeters at sea in the next 30 years as there is no development space left in land cities…
This mean that the equivalent of 780.000 Empire state buildings needs to be built at sea. 26.000 Empire State Building per year…every year…in the next 30 years.

That makes more than 70 Empire State Buildings per DAY !!! to build on the ocean during the next 30 years just to keep up with the demand.

The Empire State Building holds 257.211 real estate square-meters on 102 floors and can host 6430 people in 40 squarmeter apartments.

Any architect and real estate investor who is not “looking into large scale oceanic real estate development” by now, will look like a Neandertal in a few years.

Not convinced?… hear little talk about oceanic real estate?… Remember Internet ? nobody “saw it comming” nobody was “planning for it” – looks so obvious now … – is dominating everything… we live in the 40 years where humanity is struck by wave after wave of groundbreaking technological change – faster than anybody can imagine it – ocean colonization is the next big thing to come.

One of the best ways to get started with ocean colonization is, to cook it down to a simple real estate deal. You produce 1 squaremeter of useable space at a cost of USD 166 (been there tested that) and you can sell that space at a price of at least 2000 USD. (check oceanfront real estate prices)

Any real estate agent can understand that business, any investor and any bank can understand it. It looks feasible and desireable business in any business plan.

This is why we should not go with “complicated turnkey concepts” but simply try to establish a fabrication site for “floating real estate squaremeters”.
Creating oceanfront real estate by building sandbanks is a fairly common and well understood business that is going off on large scale in Dubai and other locations. It is a central paradigm of the real estate business that space can not be created but is limited – especially oceanfront space.

Concrete float solutions expand the sellable real estate to the water – this should be a desireable business field for investors that normally have no affinity to “boating” of any kind.

So to start with i would just sistematicly mass produce floating “empty building lots on the water” and offer them for sale. This is a simple deal, with a never ending pool of possible customers, easy handle for established real estate businesses.

Concrete has clearly emerged as the most economical and durable material for the building of the vast majority of marine structures. Reinforced concrete too has overcome the technological problems making it a suitable material for the construction of advanced marine structures such as offshore drilling platforms, superspan bridges and undersea tunnels. As the world becomes increasingly ocean-oriented for energy and other resources it is predicted that construction activities during the 21st century will be dominated by concrete sea structures. The performance of concrete in the marine environment is presented here in a logical manner giving state-of-the-art reviews of the nature of the marine environment, the composition and properties of concrete, history of concrete performance in seawater, major causes of deterioration of concrete in the marine environment, selection of materials and mix proportioning for durable concrete, recommended concrete practice and repair of deteriorated marine structures. It is of value to any design or construction engineer responsible for marine structures.
