How to protect yourself from sea robbers

22.01.2001

Japanese designers are developing ways to protect against the attacks of sea pirates, which suffer ships in Southeast Asia.

The Togapotop system (translated as "tiger cage") reacts to the hit of metal hooks, which are the main weapon of pirates, on the deck of the ship. When hit by such hooks, the wire stretched along the sides bends or breaks, as a result of which a system of mirrors and fiber optic cables is activated, and a powerful searchlight is turned on, illuminating the place of attack.

Another system - Seajack Alarm - is based on the use of satellite tracking of the location of ships, speed and direction of movement.

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, ... >>

Medical mask that you can eat in 31.05.2020

Now the whole planet is forced to wear masks in order not to catch Covid-19 - they are uncomfortable, unusual, hot, but relatively safe. Since the coronavirus pandemic has been with us for quite a long time, there were craftsmen in the world who decided to slightly modernize this accessory so that, for example, you can eat in it.

Yes, it is obvious that sane people are unlikely to do this in those places where you can pick up something, but this is not about today, but about the near future, when such properties of masks can really come in handy. This concept was developed by employees of the Israeli company Avtipus Patents and Inventions.

A special switch is attached to the mask, by pressing on which it can be opened at the right time. So far, this mask is easy to use with solid food, but sauces and ice cream can be a problem.

At the moment, the company has only filed a patent for the development, but its employees are preparing to launch mass production soon and promise that the mask will open automatically when a cutlery is brought to it.

Employees at Avtipus Patents and Inventions do not see their mask as something funny and claim that with the help of their product, people will feel calmer in restaurants and other public places for the first time after the threat of the virus subsides.
