Context : humanity growing out of its childhood pants becoming a level 1 civilization getting its shit together on the planet and become “spacefaring” in serious terms.
Seasteading will have a central role in that ( sustainability on the planet )
While some industries like the pharmaceutical/medic industry will go oceanic due to their suffering from “sofocating third party interference” other business is “MARINE by its very nature”… For example you can build, handle, and commercialize, that “space payload launcher” only at sea and nowhere else on earth, especially not on “tierra firme”.
Only the sea allows to put a mile of tube some 45degree vertical move it around to point at a specific coordinate and fire a payload into outer space.
You need very little support structure as the bouyancy provides the support and the dampening
A hyperloop style sistem with enough tube length could also be feasible to launch space ships with a bearable acceleration
interference free oceanic space ports
Space X landed a reusable rocket on a oceanic platform - this lays the groundwork for oceanic space ports.
From Space Launch to Seastead
In addition to his in-person duties, Elwartowski was also administering a web forum for the Seasteading Institute. There, in March 2018, a 50-something German software engineer named Rudiger Koch began pushing a concept that became Ocean Builders, an operation to design, build, and sell small seasteads. According to Koch, the Andaman Sea in the eastern Indian Ocean had historically calm waters generally free of threatening storms, making it an ideal location for floating experiments.
Koch showed Elwartowski a picture of a concrete spar he’d helped build, though “I really had no idea what he was actually doing,” Elwartowski recalled a year later. When they first met in Bangkok around September 2018, Koch seemed more excited about building a “launch loop” in the style of Keith Lofstrom, an electrical engineer and space enthusiast who has long hyped designs for a cable loop system that could propel payloads into space without rockets.
As Elwartowski explains it, Koch wanted to “launch things with electromagnets up in space” and thought the smartest place to build a launch loop would be out on the open seas, since Lofstrom’s design is more than 1,000 miles from end to end.
Elwartowski is no aerospace engineer, and lots of the technical details were hazy to him, despite plenty of listening to Koch “talking technically like an engineer” with his “very heavy German accent.” But Elwartowski says the ocean was important to Koch as a gateway to space; seasteading was just a way to ensure the engineers and workers needed to build his launch loop would have a place to live in the deep ocean.
“This initial phase was definitely not the end goal,” Elwartowski says. For one thing, the water where he and Summergirl so briefly floated was too shallow for the space launch, and while their temporary home floated on an anchored spar, Koch eventually wanted “floating homes with dynamic mooring, motors that can move them.”
Koch hired Thai locals to build a steel spar to replace the initial concrete one, which had cracked and sunk. Watching metal cylinders get welded together, Elwartowski and Summergirl decided they could help promote the project by occupying and publicizing this first seastead. The Ocean Builders website tried to gin up customers to buy their own houses-on-a-spar, creating a small seasteading village. It would be parked safely, they all thought, outside the 12 nautical miles that generally defines an ocean-bordering nation’s sovereignty. But as they would soon learn, governments often try to enforce their will on a “contiguous zone” twice as extensive.
Remembering the local discontent in Tahiti, the Ocean Builders team thought it better to keep things under the radar until it had demonstrated that its one small houseboat could withstand the rigors of the water, that this whole crazy dream could actually be true. The group totally intended, Elwartowski says, to work with whatever Thai authorities might actually care, especially if Ocean Builders got real clients with real money on the line to add to the community of small seasteads. (While hundreds expressed some interest in doing business with Ocean Builders, no actual cash was laid down before the Thai crackdown, though Elwartowski says big money interested in underwater restaurants and Airbnbs was sniffing around.)
But they weren’t stressing too much about making things official. They figured no government would freak out over “one little small floating house in the water,” Elwartowski says. The total cost of the project would be a mere $150,000. “How can they be afraid of that?”
advanced cement composite technology | need help? - our group has a grip on that tech - been there done that - tested it all - works perfectly…it´s about “getting the combinations right” concretesubmarine.com
Postulate: it is feasible to build a tubular cement based composite structure that reaches from the mid ocean depth bottom to the surface.

The system in that first picture is known as the QuickLaunch and is a light-gas gun type launch system. It is used to propel small shell-like capsules to LEO orbital velocities. It fires them at extremely high velocities and so is only suitable to very simple compact payloads such as basic materials and very solid-state microsatellites, though it can launch them in great number with quick turn-around-time between launches. The QuickLaunch developers suggested its key use as a fuel transport system. Consequently it has long been overlooked by space agencies who lack the imagination to envision any use for that --as we completely lack any practical means to make and build in space and figuring out how to do that was never a space agency priority…
Rockets can actually be launched quite well from in water itself. The original Zenit rocket was designed for this purpose, having been developed as an early ship/sub-deployed ICBM. Rockets can float quite nicely on their own in a vertical position when put in the water and thus launch with nothing more than a ship to carry them out to sea and support umbilical cable. This approach was planned for a rocket system called Aquarius proposed by Space-Systems Loral in California which was intended to supply low value payloads (food, water, clothes, oxygen, fuel etc.) to the ISS as a cheaper alternative to supplying that with the Space Shuttle.
The purpose of launching in the water was to allow a low but tolerable engineered reliability for the rockets which would be mass-produced. Launching in water eliminates the potential for damage to structures and property when a rocket fails, making a higher rate of failure relatively safe. In this way Aquarius could achieve a very low cost to orbit as the cost of engineered reliability is what really drives launch costs. Sticking to simple payloads of low value overcomes that. A low-rel rocket for the low-value payloads. That’s the real solution to ‘cheap access to space’ or CATS --the perennial obsession with the space industry. Again, NASA couldn’t see the point. Once the ISS had been assembled, NASA still had to use the Shuttle to get people there and all that extra cargo space was ‘free’. And then the Shuttle failures added up and it went obsolete…
As urban encroachment and sea level rise take their toll on the mostly coastal launch sites, launching rockets at sea will become a necessity and so the idea of using space centers and launch services as a premise for starting marine settlement makes a lot of sense. This was the premise of the marine stage of development in Marshal Savage’s “The Millennial Project.” There the chief role of the marine settlements as space centers was not launch but recovery, as that plan called for the development of a mountain-based hybrid laser/magnetic accelerated shuttle system with glide recovery vehicles. Unfortunately, that concept proved unworkable on further research. The idea of using mountain slopes as support for the system still introduced too much centrifugal force for human transport.
In my own work on revising TMP (as president of the space advocacy group formed to pursue it) I replaced this launch system with the near-term strategy of Aquarius-style minimalist in-water-launched rockets and the active pursuit of in-space industrial capability to minimize payload values. I even anticipated the use of 3D printing for rocket construction. This would be complimented by necessarily more expensive, potentially reusable, manned systems, but still sea-launched and minimalist in design as they needed no cargo capacity of their own once a robust in-space industrial infrastructure was established. There really isn’t much of a point to launching astronauts with much more than the clothes on their backs… Ultimately, the marine colonies might become down-stations for space elevator systems, pairing in-space production to local complementary on-earth production.
Earth Escape Velocity is Mach 33 | Hyperloop is at Mach 1 for now so there is still some development to do…sistems combining a hyperloop capsule with a rocket could be feasible…
