    UK wants to build an orbital power plant by 2050

    UK wants to build an orbital power plant by 2050

    UK government commissioned a study to assess the cost-effectiveness of a solar power plant in geostationary Earth orbit.

    When solar panels are operated on the planet’s surface, their overall efficiency is significantly reduced due to a number of physical factors. They do not generate electricity at night, they do not work well in cloudy weather, without special mechanical systems, their power fluctuates depending on the angle of incidence of rays during the movement of the Sun during the day, some of which are absorbed by the atmosphere. All of these factors disappear when the panels are installed in space..

    The UK space agency was interested in such an opportunity and instructed the consulting company Frazer-Nash to study the issue. The research team will study not only the feasibility of the project from the financial side, but also the specific technical features of construction, possible solutions to maximize efficiency, as well as the impact on the country’s energy sector.

    UK wants to build an orbital power plant by 2050

    All the necessary technologies to create a space solar power plant have existed since the 80s of the last century, but until now such projects have been postponed due to the complexity of implementation and high costs. That changed in early 2019 when China announced it was designing a space facility. for converting solar energy into electrical energy, with its subsequent transfer using a laser or microwaves to the Earth.

    Frazer-Nash Consultancy will work with space organizations, energy companies and scientific institutions to determine the best way to transfer the energy produced in orbit to the surface. In case of a positive assessment, the government plans to implement the project until 2050.

    Advanced jet wings allow vertical takeoff from the ground

    First F-35B Vertical Takeoff Test

    The inventor of jet wings, Yves Rossi, developed an autonomous take-off and landing system that allowed him to rise vertically from the ground for the first time..

    Before the launch took place in the air, and the pilot had to fall out of the plane or helicopter each time before starting to fly on his own..

    Recently, Yves Rossy teamed up with a Swiss engineering team to develop a self-balancing runway system, as well as more powerful Jetcat P550 jet engines on the wings, which provide enough thrust for vertical ascent at speeds of up to 180 km / h..

    During an open demonstration over the lake, he was able to take off without any problems and softly landed on the platform, while looking completely relaxed. However, Rossi said that landing on the second flight was a little more difficult than the first, making him a little anxious..

    China has created a magnetic levitation train that reaches 600 km / h

    China unveils state-of-the-art maglev train prototype designed to travel at 620km/h

    Chinese engineers presented a prototype of an experimental Qingdao magnetic levitation train, which is capable of traveling at a speed of 600 km / h and will compete with passenger planes in travel time.

    According to the developers, powerful electromagnets keep the presented Maglev at a distance of a thumb from the rail, which ensures a quiet and smooth ride at high speeds, close to those of an air flight. The body of the new train consists of ultra-light and high-strength materials..

    Engineers had to solve complex physical problems associated with high speed, productivity and efficiency. It took a team of specialists from over 30 enterprises, universities and research institutes three years to create Qingdao.

    The developers say that Maglev will eliminate the advantage of aviation over ground transport at a distance of 1,500 km. The flight from Beijing to Shanghai takes 4.5 hours, including preparation time, and Qingdao will get there in 3 hours..

    Initially, full-scale testing was planned to begin in 2020, but the presentation of the prototype may change the further schedule. Mass production of new trains should begin in 2021. At the same time, the high-speed transport network will be expanded to the whole of China, since the economic feasibility of operation is strongly influenced by economies of scale.

    China has created a magnetic levitation train that reaches 600 km / h

    The researchers also said that a magnetic levitation vehicle is already in development, moving in a vacuum tube, which will be able to reach speeds of 1000 km / h..

    Recall that in February, India announced plans to create the fastest in the world of the transport system of cargo transportation based on the project of a high-speed vacuum train.

    A new method for producing plutonium-238 invented

    2 Comments

    How to make Plutonium

    Physicists at Oak Ridge National Laboratory (ORNL) have developed a new method for the automated production of plutonium-238, which will increase its production eightfold.

    Previously, a radioactive isotope was mainly needed for nuclear weapons, and now it is used for medical sterilization, artistic restoration, power supply of spacecraft systems and other peaceful purposes. After the end of the Cold War, many governments scaled back their national production programs, although need in radioisotope preserved. ORNL researchers have been making it by hand, but recently figured out how to automate the process..

    To do this, they form neptunium-aluminum oxide granules. Neptunium is also a radioactive metal element, and if the granules are further irradiated, the so-called neptunium-238 is created, which quickly decays and forms usable 238Pu.

    A new method for producing plutonium-238 invented

    According to scientists, partial automation of production will increase the annual production of plutonium from 50 g to 400 g. Additionally, the reduction of manual operations reduces the level of potential risks..

    Chinese scientists have also made incredible progress in transforming atoms. They were able to turn copper into an analogue of gold.

    New non-electric system can simultaneously cool the building and heat the water

    Unique Heating, Cooling and Hot Water Solutions for Multi-Storey Buildings

    Scientists have developed a prototype of a hybrid device that can not only reduce the temperature in a building by 12 °C without electricity, but also heats the water due to sunlight.

    Heating and air conditioning systems are among the main consumers of electricity. Therefore, researchers are improving radiation cooling systems. and heating for light renewable energy sources. Now a team at State University of New York at Buffalo has combined the two concepts in one device..

    To create it, the researchers installed a heat emitter in such a way that heat from the room was collected from both sides of the panels and transferred into the open space in the form of infrared waves. They positioned the thermal emitter vertically between a pair of V-shaped mirrors. In the course of experiments, the device reduced the temperature inside the test setup by more than 12 °C  in direct sunlight and at least 14 °C in simulated night time.

    The system uses mirrors consisting of 10 thin layers of silver and silicon dioxide, which selectively interact with waves of different lengths. They reflect mid-infrared waves from the emitter, absorbing visible and near-infrared rays. This improves the efficiency of the device as it prevents the sun from neutralizing the cooling effect..

    New non-electric system can simultaneously cool the building and heat the water

    Since the system reflects only part of the radiation, the team decided to use the absorbed energy to the advantage. During tests, researchers were able to use it to heat water up to 60 °C.

    The current prototype is only 0.7 m long.In the future, scientists plan to scale the device to the size of the roof.

    Scientists have made fiber from algae

    Researchers have created biocompatible, biodegradable and edible fiber from natural gel that can have many medical uses.

    The team of scientists from the University of Campinas used conventional agar-agar made from seaweed as the main material for the optical fiber. The wire they created with a diameter of 2.5 mm has six cylindrical holes of 0.5 mm along the inner axis. They are located around a solid core and prevent light scattering due to the difference between the refractive indices of the gel and air..

    Waveguide parameters can be adjusted by changing the composition of natural gelatin, the shape and size of the cores for holes during pouring.

    Scientists made fiber optic from algae

    Tests have shown that the gel undergoes structural changes under the influence of temperature, humidity and pH. This allows it to be used for optical sensing, the creation of biocompatible optical sensors, disposable Petri dishes, various devices for operations, research and localized drug delivery..

    Scientists are experimenting with other materials, for example, recently the Finns made fiber from cellulose.

    The new ABBYY system recognizes text as well as the human brain

    1 Comment

    ABBYY has integrated AI into its new text recognition system, which allows it to independently determine the peculiarities of handwriting or printing on individual images.

    Although programs for translating scans into an editable file appeared in the last century, their main problem was recognition by comparing elements a snapshot with a set of symbols in their database. Therefore, when processing images with minor changes, often the wrong letters were displayed, which required proofreading and manual correction of errors.

    Russian developer ABBYY solved this problem using neural networks. The presence of AI elements in the recognition system allows it to work like a human brain, determining the individual characteristics of the spelling of letters. At the same time, it does not wait for the database to be updated, but independently compares the sets of scanned characters with those already known, and expands the list of possible spellings. Details can be found in patent.

    The new ABBYY system recognizes text as well as the human brain

    This speeds up the processing of scans with imperfections, documents with displaced lines, poorly printed elements, and images with hieroglyphs, Arabic script.

    However, competition in this market continues to intensify. In May, Amazon also introduced a new Textract service AI-powered document processing that fully automates data entry.
