Japan to build a network of orbital energy platforms

18.05.2014

According to the Japanese space agency, platforms are planned to be launched into geostationary orbit to collect solar energy and transfer it to Earth.

The tragic events at the Fukushima nuclear power plant prompted Japanese scientists to such an unusual idea. They believe that extracting energy in space is much safer. At the same time, it is not reported how much the implementation of the grandiose plan will cost.

It is assumed that the platforms will be located at an altitude of 36 thousand km from the Earth's surface. In addition to space platforms, it will be necessary to create a special receiving station on Earth, which will be able to receive solar energy from space.

The network of constructed orbital stations will have a total capacity of 1 GW, which, if successful, will make it possible to abandon the use of nuclear power plants. The energy will be transmitted to the Earth by means of electromagnetic radiation of ultrahigh frequency.

At the moment, scientists are engaged in compiling related maps and graphs. It is assumed that the project will be able to start in 2030. The launch of the project will be preceded by a 10 kW space farm launched 100 years earlier. It will be required to develop new technologies.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Created an elastic form of carbon 04.07.2017

A joint research team from the Carnegie Institution, Washington, USA, and Yanshan University, China, has synthesized a material that is carbon in a new form. This material is very, very strong, but the most interesting thing is that it has elastic properties, like rubber. What's more, the new form of carbon is capable of conducting light and electricity through itself, making it possible to use all this in a very wide range of applications, from space and military equipment to household appliances.

A new form of carbon was obtained by applying pressure and high temperature to one of the amorphous forms of carbon, which does not have an ordered structure, called glassy carbon. This starting material was placed under a pressure of 250 thousand times atmospheric pressure and heated to a temperature of about a thousand degrees Celsius. Under these conditions, carbon atoms form chains that connect to each other in various ways. And the result is a form of carbon that simultaneously has the properties of graphite and diamond.

Obtaining a new form of carbon was the result of a number of experiments. In some experiments, scientists exposed glassy carbon to high pressure at room temperature, while in others they simply heated carbon to ultrahigh temperatures. The material obtained as a result of the first experiments had absolutely no elasticity and was not able to restore its shape even after slight deformation. And in the second case, diamond nanocrystals began to form inside the carbon.

And as a result of one of the intermediate experiments, which used heating to a moderately high temperature, the scientists obtained a new carbon material that can compress more than twice as much as other carbon ceramic materials. Moreover, the new elastic carbon is able to completely restore its original shape in the place of sufficiently strong local deformations.

"Lightweight materials with high strength and elasticity are required in a wide variety of applications. In some cases, these materials are used in practice, despite their high cost, the light weight and other unique properties of such materials come to the fore," says Zhisheng Zhao ( Zhisheng Zhao is a professor at Yanshan University.
