Impossible engine successfully tested in space

21.12.2016

Chinese scientists managed to successfully test the fuel-free EmDrive engine, the principle of operation of which is still unknown. The apparatus was tested in detail directly on board the Tiangong-2 space laboratory. Now they are going to use it, in particular, on satellites of an orbital nature.

The researchers noted that since 2010, the Chinese government has been funding research on an engine that allegedly can be used to break the inviolable law of conservation of impulse frequencies.

Scientists have built several variations of the device in order to test it in zero gravity. The results of experiments that took into account the influence of various types of factors were able to confirm that EmDrive actually creates a small thrust coefficient.

EmDrive was able to develop a thrust equal to 1,2 millinewtons. The motor is a device that is designed from a magnetron and can generate microwaves by storing vibrational energy.

The unit looks like an overturned bucket. With this design, according to the engineers, it is possible to convert radiation into thrust.

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 ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Photosynthesis will help improve solar panels 03.09.2017

Georgia State University researchers are using photosynthesis to improve the efficiency of solar panels.

During photosynthesis, plants and other organisms, such as algae and cyanobacteria, convert solar energy into chemical energy, which is then used as fuel for further life.

As noted, in plants, the light energy of the sun causes the electron to quickly move across the cell membrane, and it never returns to its starting point. In artificial solar cells, electrons often return, losing energy. That is why the absorption of solar energy in plants is so efficient.

According to scientists, a close study of the processes that occur during photosynthesis will allow more efficient design of solar panels.

Plants convert solar energy ultra-efficiently, far more efficiently than any artificial solar cell. During photosynthesis, light passes through the electron membrane and does not return. The big problem with artificial systems is that the electron keeps coming back. It's a real mystery why plants are so efficient at converting solar energy.
