Biogas plants

Section Alternative energy sources. The types of biogas plants common in the world are classified according to methods of loading raw materials, methods of collecting biogas, materials used for their construction, the use of additional devices, horizontal or vertical location of the reactor, underground or above-ground design ... >>

Running lights on 8 channels

Section Lighting. An 8-channel automatic setting, Running Lights, is available to provide more dynamic lighting effects. The peculiarity of this system lies in the way the lamps are connected in garlands. The functional diagram of the installation is shown in Fig.1. In this scheme, the lamps are connected in a matrix circuit and connected to the mains through two groups of electronic switches. The first group of switches is controlled by the first four channels of the control circuit, and the second by the other four channels. ... >>

Features of replacing radio components in circuits

Section Ham Radio Technologies. When assembling a circuit you like or repairing radio devices, sometimes it may be difficult to purchase a particular part. What can replace it? To answer this question, you need to know the main features of the parts and have a good understanding of the principle of operation of the circuit in which this part is used, which will allow you to evaluate the limiting modes for a particular node. Most of the parts can be easily replaced with similar ones, similar in parameters, without losing the quality characteristics of the device. This is often explained by the fact that the designer of the scheme, when choosing a particular type of element, often focuses on the list of parts easily accessible to him. ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project.

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

3000 hp electric car 03.10.2013

Now electric cars are inferior to cars with classic internal combustion engines in almost everything, except that they have zero emissions of harmful substances. Serial machines with an electric drive really cannot compete with conventional models, not in terms of speed, or in terms of range, or in terms of engine power. But the Venturi VBB-3 prototype can.

The Venturi VBB-3 is a one-of-a-kind electric vehicle capable of reaching speeds of 700 km/h. True, such results are obtained so far only during laboratory tests and calculations, since testing in real conditions will begin only next year.

Of course, Venturi VBB-3 will not go into mass production, and not only because such high-speed cars have no place on city streets. It is designed for only one pilot, that is, in terms of practicality, this car is completely useless.

In the development of an electric car, Venturi employees are assisted by experts from the Ohio State University, USA. The car weighs as much as 3200 kilograms, which again contradicts the auto giants' current policy to reduce the weight of production cars. It is important to note here that about 1600 kilograms falls on the battery pack, without which the Venturi VBB-3 will not be able to drive.

The motor of the concept electric car develops a power of 3000 hp, that is, it is actually more powerful than any mass-produced hypercar. Its tests are scheduled for next year and will take place near the American city of Salt Lake City.
