Direct conversion of solar energy into electricity
Section Alternative energy sources. From the shortcomings inherent in machine converters, to a certain extent, power plants with so-called machineless converters are free: thermoelectric, thermionic and photovoltaic (solar batteries), which directly convert the energy of solar radiation into electric current ... >>
Metal detector on transistors with quartz
Section Metal detectors. The design offered to the attention of readers is one of the variants of metal detectors of the FM (Frequency Meter) type, that is, it is a device based on the principle of analyzing the frequency deviation of the reference oscillator under the influence of metal objects that have fallen into the area of the search coil. The main distinguishing features of this device can be considered an interesting circuit design of the analyzer, made on a Q1 quartz element, as well as the use of a pointer device as an indicator. The basis of the scheme of the considered metal detector is a measuring generator, a buffer stage, an analyzer, a high-frequency oscillation detector and an indicator device. ... >>
The design of the welding source for semi-automatic welding with a thyristor regulator
Section Welding equipment. On fig. 18.20 shows a circuit diagram of a welding source with a thyristor controller for semi-automatic welding. The source is powered by a single-phase network 220 V, 50 Hz. The basis of the source is the welding transformer T1. It galvanically separates the mains and the welding circuit, and also reduces the mains voltage to the value required to power the welding arc. Alternating voltage from the secondary winding of the transformer T1 is fed to the input of a controlled full-wave rectifier VD7, VD8, VS3, VS4, with which the welding voltage is adjusted. To maintain the arc in the pauses of the rectified voltage, a special two-winding choke L1 is used. ... >>

Latest news of science and technology, new electronics:
The existence of an entropy rule for quantum entanglement has been proven
09.05.2024
Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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 ... >>
| Random news from the Archive Fifth chlorophyll
02.05.2011
Australian biologists from the University of Sydney have isolated a new type of photosynthetic pigment, chlorophyll, from seaweed.
So far there have been four known. The first, the most common, is found in all plants, from the lowest to the highest. It works mainly on blue and red light, absorbing them and reflecting green (which is why almost all plants look green). Two more types of chlorophyll with a slightly different absorption range are found only in lower plants. The fourth type of chlorophyll is present in cyanobacteria (they are also blue-green algae), the range of its work is shifted to the red end of the spectrum.
A new type of plant pigment from Australian algae assimilates the energy of short-wave infrared, that is, thermal rays. This is the first such case in the plant kingdom.
