Where has bus number 20 run for more than 0 years?

Until 2002, there was a rule in Moscow - for the duration of the repair of trolleybus or tram lines, a bus with a number starting with the number 0 was allowed to run along this route. In 1995, the repair of the line on Prospekt Mira was started, but then it was closed forever. But the temporary bus No. 0 ran along the route Rizhsky Station - the Belorusskaya metro station for 24 years, but, in the end, it was assigned No. 810.

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. ... >>

solar wall 29.08.2011

From small solar panels you can assemble a "green" wall. The idea that a solar panel is a massive panel mounted on a roof is outdated.

A New York-based company called "Sustainably Minded Interactive Technology" (which means "Sustainability-oriented Interactive Technology") came up with a design in the form of sheets comparable in size to a grape leaf. You can use them in the same way as vertical gardening: fix a metal mesh on the wall and attach leaves to it.

The sun's rays will generate electricity, which will run along the grid, and at the same time such leaves will protect from heat. Leaves can be painted in all sorts of colors and attach different batteries to them. So, a sheet equipped with a polymer battery will cost $ 20, and will give energy no more than 0,5 watts, but there will be little toxic waste during its production.

Solar cells based on silicon monocrystals will cost $ 18, they will give 4 watts, but there will be more dirt. Actually, this price seems strange. After all, fans of polymer batteries all the time prove that they can be printed on a printer, which is why the price is much less than that of silicon ones.

Be that as it may, it is easy to calculate that in order to obtain a power of 10 kW (namely, this is how much they are now emitting during the construction of cottages in the suburbs), a solar wall will cost at best 45 thousand dollars, or two to three times more expensive than connecting to the network electric company.
