Build city from sea

At the risk of a lack of shelter in the third millennium, scientists have recently devised ways to use seawater to build houses, moving forward to build beautiful cities in the open sea.

A cargo ship will anchor offshore, about 300 miles from the North African coast. Sailors on the ship used a crane to lift metal-sized metal frames and large power cables out of the compartment and into the sea. Later, they began assembling solar panels together and gently laying them on the sea surface, anchoring them to the housing frame. When the ship ran away, it left behind a giant spiral ring created by floating solar panels floating on the water.

Five years later, a luxury ship arrived at that location. Instead of seeing solar panels, passengers on the deck will admire the beauty of a city with 50,000 inhabitants. This city will become the latest and most unique place for ecotourism tourists. Uniquely, all the walls in this city are built from . sea water.

Indeed, no one had ever thought of using seawater to build houses, and even built a city, an island right on the ocean's surface, except for German architect Wolf Hilbertz. This is the result of a large-scale application of ' mineral accretion ' construction techniques (mineral deposits) that he was the first to develop. If it is simply evaluated, Hilbertz was the one who invented the use of sunlight to turn minerals in seawater into limestone.

This city named Autopia Ampere began construction with the anchoring of wire meshes made of metal mesh into an undersea mountain. As soon as the wires are dropped, they will be connected to a DC power source with a low voltage due to the solar panels floating on the water. Over time, electrochemical reactions will attract minerals in seawater and accumulate them around wire molds, creating walls of calcium carbonate (which we often call limestone). Of course, according to Professor Hilbertz, wire molds must be made of titanium to withstand the effects of electricity and seawater for a long time. Limestone forms on these metal wire molds that are stronger than concrete.

In fact, Hilbertz's idea was ' activated ' just like the theory. He began modestly by creating limestone around wooden piles wrapped with steel wire at 30 piers on the coast of Texas, Louisiana and California. He is currently a professor of architecture in Germany and is undertaking a larger project using the same technology to create reefs off Jamaica. In partnership with Negril Reef Protection Association, Hilbertz has five artificial reefs around the island. 3 of the 5 experimental rock projects use shore power, the fourth project uses batteries from seawater and the last project uses solar batteries.

Plan for the city on the ocean

Hilbertz intends to create a closed island city, able to sustain itself. This island city will be located in the waters of Seamount Ampere, in the middle of Madeira Islands and Cape Portugal (Portugal), where it is less than 15 meters deep. In addition to the advantage of shallow water, the island is also home to a rich source of seafood, with favorable ocean currents and a sea floor with many metal mines such as copper, cobalt, manganese, nickel, iron .

A giant limestone dam will be built around to protect the city. Complete parts for infrastructure construction are also created from the sea itself. Solar generators and wind power will provide electricity to the city. In addition, thanks to a thermal energy conversion system, the temperature difference between different ocean currents will also be used to generate electricity.

The production and trading of limestone will give this city a significant source of income.'Compensation' technology will not only be used to create reefs in the Caribbean or build future cities on the sea, but can also be used to produce complete parts for construction on land. Just using a properly shaped wire frame, precise size, the minerals deposited from seawater can create building blocks, wall panels, ceilings or complete structures of a building. land. Hilbertz envisioned one day that these products would be carried directly from the sea to large ships and distributed throughout ports around the world.

Hilbertz also thinks about the possibility that cities on the sea will become the center of the ocean bottom industry. The sea floor has a lot of metals and minerals. Metal refineries in these cities will specialize in producing pure metals. Even though metal refining costs a lot of energy, that is not a problem. Hilbertz described very excitedly a unique hydroelectric plant that could help solve this problem. From seawater, people made limestone pipes. These pipes will lead slow-moving ocean currents deep through the turbines of giant power plants .

These cities rising from the sea can stand on their own and become independent and autonomous regions. In the third millennium, people will inevitably face extreme crowds. The time has come for us to find the appropriate ' new lands '. In parallel with finding ways to bring people to the moon or Mars, the sea and the oceans also began to be more thoroughly ' watched ' by humans. With the blueprint of Hilbertz, new cities growing in the vast sea are no longer illusions.
