Use of solar energy



Section Alternative energy sources. In most parts of the world, the amount of solar energy that hits the roofs and walls of buildings far exceeds the annual energy consumption of the inhabitants of these buildings. Using sunlight and heat is a clean, simple, and natural way to get all the forms of energy we need. Solar collectors can heat homes and commercial buildings and/or provide them with hot water. Sunlight concentrated by parabolic mirrors (reflectors) is used to generate heat (with temperatures up to several thousand degrees Celsius). It can be used for heating or for generating electricity. In addition, there is another way to produce energy with the help of the Sun - photovoltaic technology. Photovoltaic cells are devices that convert solar radiation directly into electricity. ... >>

New schemes of super-regenerative radio receivers for VHF experiments



Section Radio reception. The article N1TEV New Super-Regenerative Circuit for Amateur VHF and UHF Experimentation describes several circuits for super-regenerative VHF radio receivers. The author describes the history of creation and the principle of operation of such receivers. Their classical schemes on lamps and transistors are given. For example, Figures 1...3 show diagrams of super-regenerators at 144 MHz, made according to traditional circuitry. ... >>

VHF radio frequency synthesizer



Section Frequency synthesizers. When working on the design of a VHF radio station, I faced the task of building a simple frequency synthesizer 144 - 146 MHz. Looking through the designs of different synthesizers, I came across the synthesizer of Mikhail Kislinsky (RX9CBI). I really liked this design for its simplicity, the absence of scarce components. However, I was not satisfied with the control using the switches. Therefore, I decided to finalize the scheme, introduce a number of additional features into it. In the process of finalization, the circuit diagram was changed only cosmetically, it is still based on the RX9CBI circuit, and the program had to be completely rewritten ... >>

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 ... >>

4 TB by Western Digital 29.11.2012

Western Digital has announced the availability of the 4TB WD Black hard drive. The device is available in a 3,5-inch form factor and has a spindle speed of 7200 rpm (model WD4001FAEX).

With high performance, the drive is designed for gaming PCs and workstations, explained the press service of WD. WD Black is equipped with 64 MB of cache memory and a SATA interface with a speed of 6 Gb / s. Technologies applied include IntelliSeek, StableTrac and NoTouch - which reduce power consumption, vibration, noise and improve reliability.

The WD4001FAEX hard drive went on sale for a retail price of $339.
