A floating city will be built in the Pacific Ocean

30.01.2017

In early 2017, the authorities of French Polynesia signed a memorandum of understanding with the American Seasteading Institute, which plans to build the world's first floating city in the country's controlled part of the Pacific Ocean.

The competition for the best architectural project of the floating city was held in the spring of 2015. The first place in it was taken by "Artisanopolis" (Artisanopolis), developed by the Roark 3D group. Now that a platform for the implementation of a unique project has been found, the institute's experts will have to find out how the emergence of floating communities will affect the economy and ecology of the region. In addition, they plan to develop a special management scheme for such cities, which will require serious legal research. Initially, mobile communities were supposed to drift in international waters.

Aspects of managing the future city in the waters of French Polynesia are to be discussed with the authorities of the region and France, which controls the territory. Creating a community on a platform in the open ocean, away from the coast of French Polynesia, is possible, but not economically viable.

The main advantage of floating cities, according to the scientist, is that their inhabitants will be united by a common voluntary choice: “They will form communities guided by their own interests, instead of living side by side simply because they were born in the same place and because of belonging to one or another nationality.

The agreement between the Seasteading Institute and the government of French Polynesia will be finalized and is expected to turn into a full-fledged bill by the end of the year. If adopted in 2018, the creation of the world's first floating community will begin as early as 2019.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

The Milky Way is Bigger Than Thought 07.07.2013

A new study by scientists at the University of Colorado Boulder using the Hubble Telescope shows that the Milky Way may actually be much larger than previously thought.

Studies of spiral galaxies like ours have shown that they are surrounded by a halo of gas more than 1 million light-years across. For comparison: until now, the diameter of the Milky Way was estimated at about 100 light years. Despite the fact that the density of the gas is small, nevertheless, spiral galaxies turned out to be much more massive than previously thought. The scientists calculated the mass of the haloes, which are mostly oxygen-enriched interstellar gas. This mass turned out to be large: almost the same as the stars inside the galaxies themselves. Needless to say, this discovery will seriously affect modern models of the evolution of spiral galaxies, and the entire Universe as a whole.

Why has such a significant mass of matter not yet been discovered? Everything is banal: the halo around galaxies is cold and contains too rarefied gas. It is not known when it would have been discovered at all, if not for the calculations carried out by NASA specialists in 2009, when the installation of the COS spectrometer on the Hubble telescope was being prepared. Then theoretical studies showed that spiral galaxies seem to have about 5 times more gas than was observed by astronomers. Only now, thanks to Hubble's observations, it was possible to find part of the "missing" gas.

A very complex technique was used to detect a highly rarefied gas. Scientists used distant quasars (superbright massive black holes) as "flashlights" that shone through space and made it possible to record the passage of ultraviolet light through the haloes of gas around galaxies. Then, using the COS spectrometer, the chemical composition, density, velocity, and other characteristics of the galactic gas halo were studied.

At present, astronomers are busy carefully studying the phenomenon they have discovered. Scientists are very hopeful that the Hubble Space Telescope will continue its work. The fact is that the James Webb telescope, announced as Hubble's successor, cannot observe in the UV range, and most likely its capabilities will be mainly directed to the "fashionable" topic of searching and studying exoplanets.
