    If you position the community correctly, and take ‘ownership’ of the sea floor below it, you can be sitting on top of a gold mine, of sorts.


    Collecting the rare-earth minerals doesn’t seem to be similar to the giant straw in the ground approach of oil extraction. You may end up needing many more people than on an oil rig (I’m really not sure), and you’d probabaly want the flexibility to move your extration team around. On the surface, this seems to be an industry that Seasteading would work extremely well with. So, instead of Seasteading being seen as libertarian kooks or tax-havens for bankers (those are two silly insults that came to my mind when thinking about Seasteading), the movement could be seen as providing a valuable service to all people.

    This presentation is a great graphic presentation on a seafloor mining venture, http://www.nautilusminerals.com/i/pdf/TD_Newcrest_conference_Jan2011.pdf . I find it interesting that the gold/silver ratios found in the Solwara samples at about 20 different locations are consistent with the historical 1:16 found with most mines, they range from about 1:10 to 1:20. It makes sense to use robotic equipment on the ocean floor with remote operators when needed. It would be ideal if the ore processing can happen on the floor as well, like the crawlers consume and digest the ore to harvest the valuable contents in a continuous process which recycles the chemical reagents.


    Look at that ! remember the – vent base alpha thread – deep sea mining and seasteading…

    . . .

    remember Brazil and Petrobras – presalt oil – deep sea drilling – china going for deepsea mining…

    Remember the discussion of ocean floor mining legal situation just a few months ago… things seem to change quickly…

    I like the diagram of the chemical cycles. Wish I could see it at higher resolution. It could be cool to animate it.


    Sete Brasil was designed to help meet Brazil’s goal of building drilling rigs domestically while taking some of the financial burden of their construction off Petrobras.

    Investors in the firm include banks Santander, Bradesco, BTG Pactual and Caixa Economica Federal, as well as Brazilian pension funds such as Previ, Petrobras said in a statement. Petrobras will own a stake of less than 10% in the operation.

    The rigs are due to be in operation by 2015.

    Petrobras is commissioning 28 deep-water drilling rigs to be built in Brazil as part of efforts to spur the local oil services industry and the expansion of domestic shipyards.

    Acquiring those rigs is a key part of its five-year, 224 billion US dollars business plan that is focused on the deep-water offshore region known as the sub-salt — believed to hold as much as 100 billion barrels of oil buried beneath the ocean’s surface.

    However critics say building the rigs locally will boost Petrobras costs and slow development of the offshore reserves.

    Petrobras also revealed on Monday that during the first quarter it had quickened the pace of drilling in the offshore Santos Basin.

    During the first quarter, the company drilled eight wells in the Santos Basin, home to the vast region known as the sub-salt. That compares to a total of 20 wells drilled in the area between 2007 and 2010, said Santos Basin, Chief Financial Officer Almir Barbassa.

    “That gives an idea of the rhythm of growth that we have in the Santos Basin,” Barbassa told reporters during an earnings presentation. “We have six rigs working there now, and by the end of the year we’re going to increase that number”.

    Petrobras plans to nearly double oil output in Brazil by 2020 with ambitious plans to develop the sub-salt.

    The area has become a new frontier for energy exploration even though its technically challenging fields lie at depths of as much as 7 kilometres below the ocean’s surface.

    China gets ISBA nod for deep sea mining in Indian Ocean
    Press Trust of India / New Delhi September 05, 2011, 17:18 IST

    China’s application to carry out deep sea mining and exploration activities in South-West Indian Ocean Ridge has been approved by International Seabed Authority, Parliament was informed today.

    Replying to a question in Lok Sabha on the implication of Chinese dominance in Indian Ocean, Defence Minister AK Antony said, “Government keeps a constant watch on all developments concerning our national security and commercial interest and it takes all necessary measures to safe guard them.”

    Antony informed Parliament that the China Ocean Mineral Resources Research and Development Association (COMRA) has filed its application with the International Seabed Authority (ISBA) for Deep Sea Mining Exploration Licence and for approval of its plan.

    China has sought approval for exploring polymetallic sulphides in South-West Indian Ocean Ridge.

    “The application has been approved by the International Seabed Authority in July 2011,” the Minister said.

    Meanwhile, Minister of State for Defence MM Pallam Raju, replying to a question on security implications of import from China, said government has advised Bharat Electronics Ltd (BEL) to ensure that components of encryption products manufactured by it are not imported from China.

    “Government has taken cognizance of security implications of import of electronic components from China, especially while manufacturing encryption products,” Raju said.

    Raju said, “BEL, a Defence Public Sector Undertaking (DPSU) which is a manufacturer of strategic defence electronics system has been advised to ensure that components of encryption products manufactured by it are not imported from China.”



    BRASILIA, Jan 15 (Commodity Online): Brazil is chalking out plans to build a multi-billion-dollar underwater base to guard its offshore hydrocarbon resources and to explore farther into the sea for minerals under the seabed.

    A string of commercially viable finds of oil and gas deposits on the high seas have given impetus to government plans to exploit the sea within and beyond the country’s territorial waters.

    Various plans for making the most of offshore hydrocarbon resources are in place and most plans involve close collaboration between the government, the state-run hydrocarbons industry and the defense establishment.

    Plans for an underwater “lab” or “platform” involve the government and the Brazilian navy, both of which are interested in setting up a marine outpost on the edge of Brazil’s territorial waters, allowing deeper access to the sea.

    The idea is to place an oceanographic lab at Brazil´s most remote maritime frontier to have a continuous presence and dominate an area in which hidden natural riches go beyond the pre-salt layers, the Marine Technology Reporter said.

    At the edge of the continental platform, around 350 nautical miles from the coast, the potential for mineral reserves under the seabed is considered to be very high, said the magazine.

    I assume that this will be a tube structure that leads down from the surface similar to Troll A, combined with a submarine station like the one in the pictures…

    while there is still some ocean left.

    Interesting tha Colombia’s portion of the Carribean is so huge, with them holding the islands way out in the ocean.


    This has to do with the spanish overseas empire 1500s -1800s and colombia / cartagena beeing the central part of it. After independence of cartagena, spanish territorial waters became colombian territorial waters. Colombia includes the islands of San Andres and Providencia in front of Nicaragua and the reefs Quitasuenos, Serranilla, Roncador





    A new run to unexplored territory with faboulous riches is sheduled. Those who develop the vessels to get there ( Galeons then – Undersea tech now) will be the owners of a new economic empires.

    TSI could be the East India Company of the oceanic empire if it would play its cards right and focus on developing core technology and ocean asociated business models. Richad Branson is already in with Virgin Oceanic…

    While we are talking about legal issues – China, India, Brazil is gearing up seriously…


    The catamaran float / The plate float out / The real estate squaremeter deal / The Captain Nemo float out / The bubble hotel / The current turbine / Breakwater lagoon marina / Oceanic port city design /

    The bubble hotel.

    It bases on the fact that there is a booming market for exotic hotel vacations. It ranges from Ice hotels, to tree hotels, and there is even a underwater hotel in use as we speak. Jules Underwater Lodge in Florida. There has been big intents of underwater mega hotels in dubai and fiji that folded due problems on the finance front. So it seems logical to start with a single room or a underwater cabin-pod on a low scale and take it from there.



    The Draupner new year wave was the first registered freak wave (rogue wave) registered in history. It came out of nothing in a 4m wave ambient and had some 25m.

    The Draupner wave or New Year’s wave was the first rogue wave to be detected by a measuring instrument, occurring at the Draupner platform in the North Sea off the coast of Norway on January 1, 1995. Prior to this measurement, such freak waves were known to exist only through anecdotal evidence provided by those who had encountered them at sea.

    Minor damage was inflicted on the platform during this event, confirming the validity of the reading made by a downwards-pointing laser sensor. In an area with significant wave height of approximately 12 metres (39 ft), a freak wave with a maximum wave height of 25.6 metres (84 ft) occurred (peak elevation was 18.5 metres (61 ft)). Engineer Paul Taylor estimated the Draupner wave was a one in 200,000 wave.

    . . . . .

    Until the size of the floating city is such that Draupner waves are manageable – which means the wave size is small compared to the structure size.

    Until that size of structure can be built on the ocean – seasteading should go for submerged living space. There is a good reason why mother nature never developed a surface swimming animal and the ocean surface is a biological desert – all animals live BELOW the surface – for a good reason.

    Wow! Wil, the amount of research you can produce is absolutely astounding.

    I think a dual location colony would be a valuable asset for mining. One on the surface, and one on the seabed. ‘Miners’ might need to stay for months below the surface, to become acclimated to water pressure, who knows?

    This setup would be incredibly complex, and would require hundreds, probably thousands of people (and people to service those people, etc). This could easily turn into a semi-nomatic colony. And if it generated revenue, it would be much easier to find investors than simply a Libertarian ocean resort.


    By the way, apparently the areas to the east and west of Hawai and French Polynesia have very large rare earth deposits (and volcanic activity) which would be productive for hundreds of years if the researchers cited in this article are to be believed:



    By the way, I think I read you live in Colombia. How are things there? I have read some articles describing an upcoming collapse of the US, EU, Japan and China. I.E., the Northern Hemisphere, except India and Singapore. Many of these same articles also describe a growth of wealth in the Southern Hemisphere: in Australia and South America (Colombia, Brazil and Chile chief among them). Do you see things playing out this way?


    pie, it looks like TSI is closing down the forums – so may i suggest to have this theme discussed in a moderated space here

    As far as I’m aware, closing the TSI forums is no longer under consideration.
