Movement speed record using magnetic levitation

26.04.2016

The Shanghai Maglev, the world's first commercial maglev railway line, holds the maglev continuous speed record of 431 km/h. (The one-time record for passenger trains was set in Japan last year at 603 km/h.) But the absolute record belongs to the 846 US Air Force test squadron at the Holloman Air Force Base near the city of Alamogordo (New Mexico), which is engaged in "horizontal flights" - launching special rocket sleds along various high-speed tracks.

The most famous is the 6m Holloman High Speed Test Track, which set the world rocket sled speed record of Mach 212 or 2003 m/s in 8,6. And on another track, 2 meters long, equipped with superconducting magnets, the 885 Test Squadron just set a new world record for a magnetic levitation sled - 640 km/h. Moreover, this is the second record in a row - a week earlier, testers dispersed a magnetic sled weighing 846 kg to a speed of 1018 km / h. The previous record, 907 km/h, set at the same test site, lasted more than two years.

It took military engineers six months to prepare the current record races. To ensure superconductivity, the magnets were cooled with liquid nitrogen to plus four degrees Kelvin. Despite the impressive speed, the engineers of the test squadron believe that this is not the limit. Their goal is to achieve hypersonic speeds of Mach 10 or 12 km/h, and designers are already working on using lighter materials in the sled for the next record.

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, ... >>

Self-propelled smart chairs 17.08.2017

"Smart" self-propelled chairs for people with disabilities will be tested by the Japanese corporation Panasonic in one of the largest transport hubs in Tokyo - Haneda International Airport. It is expected that this and other developments will be widely used already in 2020 during the Summer Olympics in Tokyo.

As the name implies, Panasonic's robotic chair will move by itself - with the help of a built-in motor and batteries. Users will be able to control the device through an app on their smartphone. Built-in sensors and an image recognition system will allow the chairs to literally "see" obstacles in their path and freely navigate the airport even in the crowd - by analogy with how Panasonic HOSPI robots navigate the terrain. By constantly monitoring its position, the robotic seat will be able to choose the best routes for movement.

"Smart" chairs will even be able to communicate with each other and, if necessary, "stray" into groups - for example, when a family, several disabled people or elderly people who have problems with the motor apparatus move around the airport. If a passenger arrives with luggage, the seat will “see” a sensor-equipped trolley, onto which hotel employees will load the suitcases, and go after it.

One battery charge is enough for the chair for about 25 km, the speed reaches 8,9 km / h.

Smart self-propelled seats were developed by Panasonic Corporation in collaboration with Whill as part of a program to equip airports in Japan with robotic assistants for tasks ranging from cleaning and transporting cargo to informing passengers. Panasonic, which has been an IOC Global Partner for almost 30 years and provides the Winter and Summer Olympic Games with audio and video equipment, expects new developments such as smart seats to help improve the transport accessibility of Japan's major infrastructure facilities ahead of Tokyo 2020.
