    Siemens launches the world’s first 10 MW wind turbine with a 193-meter propeller

    Siemens Gamesa installs its offshore Direct Drive wind turbine number 1,000

    Siemens Gamesa Renewable Energy (SGRE) launches the world’s first 10 MW offshore wind turbine that delivers maximum power output at all wind speeds.

    Such a huge power indicator was achieved thanks to the increase in the rotor diameter to 193 meters. Moreover, the length of each individual blade is 94 meters, which is comparable to the length of one ordinary football field. The working area of ​​the screw rotation is 29,300 m2. A system of 20 such wind turbines will be able to cover the annual energy consumption of a city the size of Ryazan or Tomsk.

    Direct drive technology reduces the number of rated and wear-prone components in offshore turbines, making them easier to service. Efficiency is increased by using a permanent magnet generator. The wind turbine is equipped with a High Wind Ride Through energy generation stabilization system, which in strong wind conditions (more than 25 m / s) does not turn off the device for self-protection, but gradually reduces the output power, providing a smooth decrease in performance, which increases the stability and reliability.

    The cast epoxy blades are reinforced with fiberglass to increase strength and protect against damage. Special sensors help to detect anomalies and prevent possible failures, which continuously transmit data to the control center. Siemens Gamesa plans to start commercialization of SG 10.0-193 DD wind turbines in 2022.

    Earlier we wrote that the University of Lancaster invented a new version of the rotating wind turbine, which is capable of capturing wind in any direction and is optimal for working in urban environments..

    Scientists have created a device for the production of oxygen from moon dust

    Scientists Are Making Air Out of Moondust for Lunar Settlements

    Researchers at the European Space Agency are developing a system that can produce oxygen from lunar dust (regolith). Technology will help future settlers extract air and industrial materials.   

    Analysis of lunar dust samples delivered to Earth during missions «Apollo», showed that it contains 40-45% oxygen. However, it is not so easy to extract it, since the gas in the regolith is in the form of oxides as part of various minerals and glasses. To address this issue, a team from ESA is currently testing a prototype of a miniature lunar residual soil recycling plant..

    Extraction of oxygen in it is carried out using molten salt electrolysis. For this, the regolith is placed in a metal basket. with molten calcium chloride salt heated to 950 °C, which acts as an electrolyte. Under such conditions, the lunar dust remains solid, but when an electric current is passed through it, the oxides are split, and pure oxygen begins to migrate through liquid salt accumulated at the anode.

    A by-product of this process is various metal alloys that are suitable for further use. Therefore, the team is also exploring ways to recycle and use these metals in lunar environments, such as 3D printing..

    So far, researchers transform only an artificially created regolith, but it is hoped that the technology will also work effectively with real material. The final version of the system, which can function in low temperature and gravity, like on the moon, is planned to be developed by the mid-2020s..

    Although humanity will not soon be able to transfer industrial production to the satellite, but such devices will help the first explorers and colonists to obtain oxygen for breathing and fuel, as well as metals for the repair of equipment. ESA also plans to use regolith as an affordable building material and store of value solar energy.

    Created a self-healing filter that does not allow bacteria and gases to pass through

    Tips for BLOATING with Crohn’s Disease

    Mechanical engineers at Pennsylvania State University have created a fluid membrane that allows large objects to pass through and traps small objects. The material is self-regenerating, stabilized, has many properties of the cell membrane and is the complete opposite of a conventional filter..

    The simplest example of a filter is a sieve. If sugar and peas are poured into it, then it detains larger objects. The invention of the Pennsylvania scientists works the other way around. The principle of operation of a liquid membrane is based on kinetic energy, which is usually proportional to size, to achieve the desired reversing effect. After passing the object, the shape is completely restored like a layer of surface tension on the top of the glass.

    The liquid membrane looks like a regular bubble blowing ring. It is based on water and many other components, and the first prototypes consisted partially of soap. In the course of further research, the content was greatly changed. Thanks to this, the membrane has now become stronger, and also received antibacterial properties and the ability to neutralize odors. Now it can function for a long time and even blocks certain gases..

    Bugatti Chiron sets new speed record of 490 km / h

    490+ kilometers per hour | Bugatti Chiron | Speed record

    Bugatti has unveiled the fastest passenger car to date, which can accelerate to 490 km / h, but for this the engineers had to redesign and reinforce the wheels.

    Initially, the Chiron could not reach its maximum, because at speeds over 480 km / h, the wheels overheated due to strong centrifugal force and a tire load of about 7 tons, from which they were torn apart. However, the designers decided not to look for another rubber, but to strengthen the tires. and redesign the vehicle to reduce drag and eliminate downforce from both sides.

    As a result of tests at the Volkswagen Ehra Lessein proving ground in Germany, the pilot managed to accelerate to 490 km / h, installing a new world record. The track itself was perfect for testing, but it took more than five hours to clean it up at this speed. Although at the finish the windshield was littered with smudged insects.

    The Worst Bitcoin Crash In History Is Coming (Tesla Selling)

    Over the past 24 hours, the cryptocurrency market experienced another decline, as a result of which its capitalization decreased by 3.8%, and the bitcoin price dropped to $ 3590.

    In the second half of Sunday, there was a sharp collapse of the crypto market, reducing the total capitalization from $ 124.2 billion to $ 119.5 billion, but this is still almost $ 2 billion more than last Monday. Over the past 24 hours, the bitcoin (BTC) rate has fallen by 3.78% and at the time of this writing is $ 3595. Although the current value is still relatively far from the December low, and the current value is even slightly higher than exactly a week ago. Some analysts say that in the absence of significant positive developments, investors are waiting for another powerful rebound to enter the market..

    Altcoins also showed a moderate decline. Most cryptocurrencies have lost 3-6% of their value. During the day, the ripple rate (XRP) decreased by only 2.77% and is $ 0.321. Ethereum (ETH) against the background of the next transfer of the hard fork, the project suffered a more significant loss of 5.58% and is now trading at $ 117. Bitcoin Cash (BCH) and EOS Prices Drop 5% & 4.7% up to $ 123 and $ 2.36 respectively.

    Found an efficient way to convert brewery grain waste into fuel

    How Plastic Waste Is Converted Into Fuel At A New Plant In Indiana

    Researchers have developed a technology for converting barley leftovers from breweries into carbon fuel.

    Breweries dump huge amounts of unused grain every year, but chemists at Queens University in Belfast have found a cost-effective solution to convert this waste into useful products..

    The method developed by the team consists of just a few steps. First, the grain is dried, after which it is subjected to a two-stage chemical and thermal treatment with using phosphoric acid, and then washed with potassium hydroxide. After this remains activated carbon and valuable carbon nanotubes.

    The final product can be formed into pellets and used as fuel for heating houses, producing water filters or charcoal for barbecues..

    Found an efficient way to convert brewery grain waste into fuel

    Since the chemical solutions used are readily available and cheap, such processing is cost effective. In addition to the high rates of profitability of synthesis, an additional benefit lies in the parallel disposal of production waste and resource savings.

    This direction even an oil and gas company got interested BP, which plans to build new venture in Brazil and annually produce 2 billion liters of biofuel there.

    Astronomers first spot water on a potentially habitable planet

    A Potentially Habitable Super Earth Has Been Discovered

     

    Found the first planet outside the solar system, which has not only water, but also the necessary temperature conditions to support life.

    K2-18 orbits a cool dwarf star 110 light years away in the constellation Leo. It is eight times heavier than Earth and has a different composition of the atmosphere. Given the high level of activity of the red dwarf, the conditions on it are likely more hostile., as it must be exposed to strong radiation.

    Although this exoplanet will not be able to become a new home for humanity, the discovery brings us closer to answering the fundamental question about the uniqueness of the Earth..

    In their work, a team of astronomers at University College London used archival data from 2016 and 2017 from the Hubble Space Telescope and developed open source algorithms to analyze the starlight that passed through the atmosphere of K2-18b. The results showed the presence of water vapor, hydrogen and helium. Researchers believe other molecules, including nitrogen and methane, may also be present in the atmosphere, but further research is needed to find them..

    Astronomers first spot water on a potentially habitable planet

    K2-18b was discovered in 2015 and is one of hundreds of super-earths – planets with masses between Earth and Neptune – found by the Kepler spacecraft. Scientists believe many of these super-Earths will be found over the next few decades, as they are the most abundant type of planet in our galaxy, and red dwarfs are the most common stars..

    Recall that last year NASA announced that it will begin to look for signs of advanced forms of extraterrestrial life..
