Floating City Freedom Ship

30.06.2002

Norman Nixon, owner of Engineering Solutions, has designed a completely unique ship, a real floating city, called the Freedom Ship.

Freedom Ship will have 55 decks, its length is over 1 km, its width is about 300 m, displacement is 2,7 million tons (for comparison: the displacement of the world's largest supertanker Jahre Viking is 565 thousand tons). The weight of the floating city is 3 billion tons.

About 70 thousand people will be permanently on board, of which 50 thousand are islanders who own real estate on the ship, and 20-25 thousand personnel, including security services and a small army. In addition, tourists will live in hotels on board. The cost of the project is 9 billion dollars, and 22 million dollars have already been allocated for equipping the construction site alone. To date, 20 thousand residential apartments have already been sold, each costing from 80 thousand to 6 million pounds.

There are at least 50 architectural and design styles for living spaces. There will be: a library, a university, computer rooms with Internet access, a hospital. Also banks, restaurants, stadiums, casinos, courts, swimming pools, hotels, several light and processing industries and an airport. 200 acres of land allocated for parks and gardens. The floating island will make round-the-world cruises every two years, call at ports where local residents will board.

The floating island will be far more environmentally friendly than any other vessel in existence. To do this, the ship will use high-tech toilets that process wastewater. The ship will recycle paper, glass, metal and plastic. Materials not available for recycling will be incinerated and the energy from the combustion will be used to run generators.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

Headphones for heart rate monitor 04.11.2013

Kaiteki Institute and Bifrostec have developed a heart rate measurement technology that uses headphones as a sensor. The development was demonstrated at the Healthcare Device Exhibition 2013 in Yokohama.

The demo used simple consumer electronics headphones that cost less than ten dollars.

To eliminate interference, Kaiteki Institute and Bifrostec engineers developed digital signal processing technology
The development is based on the change in pressure in the closed space of the auditory canal, closed by the earpiece. The change is caused by the fact that the tympanic membrane oscillates in time with the pulsations of the arteries. The earpiece, acting like a microphone, picks up these pressure changes.

It is noteworthy that nothing needs to be changed in the headphones, so that they can perform their main function, measuring the pulse from time to time, for example, when the user listens to music while jogging.
