Flight boots

21.04.2001

Moving around the space station in zero gravity, it would seem, is easy: you have to grab onto the walls and push off objects. But, having pushed off, it is no longer possible to slow down or change the direction of the flight, and at speeds developed in zero gravity, this can be dangerous.

American engineer Philip Watts and physiologist David Carrier propose to give astronauts the means for controlled zero-gravity navigation. If you stand on the scales, raise an umbrella above your head and start clapping it, opening and closing. At the moment the umbrella is closed, the scale will show a noticeable decrease in weight. This force of repulsion from the air in zero gravity will be enough for movement. But the umbrella is too bulky, and the suit with wings like a bat proved to be ineffective.

Since human legs are stronger than arms, the researchers suggest using mainly legs to fly around the station. A simple option is boots with elastic opening bells, which you can sort of run through the air, starting from it. For large and spacious space stations, a kind of bicycle with propellers rotated by pedals will be convenient. Both options are also good because they give the body a load, which is so necessary in conditions of weightlessness.

It is difficult to say whether the Americans know that Tsiolkovsky, almost a hundred years ago, proposed wings-fins powered by leg muscles for flights inside the space station.

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, ... >>

Soil houses 21.08.2020

Experts from the American Chemical Society (ACS) presented a building material from the soil. With the help of a 3D printer, they plan to print from it at home.

The environmental impact of the construction industry is a growing concern. Some researchers have turned to additive manufacturing, or building structures layer by layer, often done with a 3D printer. This progress has begun to transform the construction sector in terms of reducing waste, but the materials used in the process must also be sustainable.

The use of concrete in the additive manufacturing of building structures turned out to be fast and cheap. However, the International Energy Agency claims that concrete production produces 7% of carbon dioxide emissions.

It is convenient to build from the soil, because the soil does not have to be carried far. This means savings on shipping costs. Additive manufacturing with the help of soil is dreamed of using for the colonization of the Moon and Mars.

Chemists treated the soil with an environmentally friendly additive to work with it without any problems on a 3D printer. The microscopic layers on the surface of the clay mixture were "buttoned" so that it would not absorb water and expand, destroying the structure. It turned out that after processing, the clay mixture holds twice as much weight.

Scientists intend to improve the bearing capacity of the soil. It is assumed that the material is environmentally friendly. If this is confirmed, the technology will be tested on other planets.
