    I don't think that region is even connected to the main Russian power grid

    And even if it was, the loses will be huge over such a long distance, and transferring 100GW worth of power (because for sure there's nothing there that would warrant even 1% of that capacity)

    Besides, who says that China and Japan would want to import such an amount of electricity rather than building up their own capacities?

    I think its only realistic use is in generating hydrogen. When the world market for that picks up, then we can see.

    Doesn't Russia have the UES(Unified Energy System)? It could just use all that power for itself and get rid of all it's older and more polluting plants in one go as well as exporting electricity and hydrogen on the side.

    Mostly it does, but some far-off areas are isolated from it, and Kamchatka is one of those places

    But even in areas connected to the grid, things are not always so simple. Energy is very cheap and plentiful in Siberia due to the hydroelectric and gas-fired power plants coupled with the post-Soviet de-industrialization of some of these places. But transferring power from there to the Volga region does not come without its losses. Hence the price of electricity in the Volga, where it's a lot more in demand, is significantly higher.

    If the network was lossless then the price and availability of electricity across Russia would be the same, excepting the difference in purchasing power across regions. It's not. In Rostov-on-the-Don it costs nearly 5x as much as it does in Irkutsk, and 2x as much as in Novosibirsk. And these regions are quite similar in terms of the average income of the population.

    In theory you could mitigate things by running a behemoth high-voltage power cable from Kamchatka to Sakhalin and from there to Japan, China, Korea, wherever. That's an option for sure, and it would provide all the power the surrounding Russian regions would ever need as well.

    But the costs would be substantial. Such a line would be over x3 times the length of any existing one, would need to be composed of a lot more individual cables to handle higher voltages just for the sake of that amount of distance, and I don't even imagine what measures you'd have to implement to enable it to transfer 100GW worth of power (!!!!!!).

    The only project that could possibly compare would be the Australian-ASEAN power link project. Which will be well over twice the length, but only a 1/30th of the capacity of a Kamchatka-Sakhalin one.

    I would imagine the costs of such a cable setup could reach $8-10 billion dollars or so.

    So.. wouldn't it just be easier and cheaper to generate hydrogen on the spot and ship it out from there instead?
    For sure though, Kamchatka would have the cheapest energy prices of any place on the planet Razz
    Couple that with its northern frigid climate. Can anyone say data mining farms and data centres? Cool

    Would be excellent for any industries that require cheap electricity, and it being clean generation is a bonus too.

    Aluminium smelting, steel making etc etc.

    I would think the tidal generators could easily be put into a large flowing river and generate electricity there too except unlike a hydro electric dam there would not be any need for a huge lake and they could be positioned along the river to allow navigation to continue for local boaties... it is not like Russia does not have a few rivers they could do this on.

    **sigh**

    Since you guys are so interested in this project, I guess I have no choice but to share the article..

    https://zen.yandex.ru/media/city_swamp/samaia-bolshaia-v-mire-prilivnaia-elektrostanciia-sdelaet-rossiiu-energeticheskoi-superderjavoi-chast-vtoraia-60c49631e188ec3c2a3348e7

    The world's largest tidal power plant will make Russia an energy superpower
    12 June

    Penzhinskaya TPP

    The answer to this question was given by Soviet engineers, back in 1972. There is a unique place in the Sea of ​​Okhotsk - Shelikhov Bay. The minimum distance between the banks in the Penzhinskaya Bay area is 130 kilometers. The largest tidal wave in the Pacific Ocean is observed here - 14 meters. By building hydraulic structures with electric generators, you can get a huge amount of electricity, without environmental consequences for nature.

    Νew Technologies and Innovation Development in Russia - Page 37 16261511

    At that time, the Penzhinskaya TPP (tidal power plant) project was not in demand. There was enough electricity in the region, no one spoke about "green" electricity in general.

    Today, a super-power plant in the Sea of ​​Okhotsk is a "saving straw" for Russia. According to the calculations of the engineers of the Gidroproekt Institute, the capacity of the Penzhinskaya TPP may be more than 100 GW. (more than half of all electricity generated in the Russian Federation). For comparison, 22 GW - this is the capacity of the world's most powerful power plant "Three Gorges" on the Yangtze River in China.

    Tidal electricity is absolutely clean. The prime cost of one MW is several times cheaper than that produced at the CHPP. The dam in the Penzhinskaya Bay will not have any impact on nature. The generated energy can be used to produce "green" hydrogen - a fuel for the future.

    Νew Technologies and Innovation Development in Russia - Page 37 16261510

    "Construction of the century" will cost "a pretty penny." The dam in the Penzhinskaya Bay, together with the power plant, is estimated at 4.5 trillion rubles. Russia spent a little less on the Olympic Games in Sochi.

    According to the Minister of Finance Anton Siluanov, the National Welfare Fund (National Welfare Fund) currently has more than 13 trillion.

    A hydrogen plant, a port for shipping products, and the corresponding infrastructure will also require considerable investments. But this is an economy, with a subsequent return on investment.

    If Russia is destined to be a "gas station country" (and there is no other way in the policy of the state), it is necessary to take a leading position and think about tomorrow. There is money in the NWF. Today they are invested in various foreign currencies and do not work for the benefit of the Russian Federation. Maybe it makes sense to spend them on the development of promising technologies in order to be "ahead of the rest of the planet"?

    This term is used by ignorant people. Russia is the 5th economy in the world with a modern economy that is one of the most self-sufficient. Just look at the import. Of course, it is also an energy superpower. Huge oil and gas deposits and infrastructure for their transmission. The best nuclear technologies, etc.

    UES is the name of the company only.
    They don't have a full cycle grid, which is impossible for a country is so huge.
    Several subsystems are isolated, for example, Yamal, Sakhalin, Kuriles, there is some serious reconstruction going on in association with BAM, so not sure how will it look finally in the Baikal area, but it used to be a separated grid, too.

    And I would add one comment here.
    All the opinions about Russia being unable of doing that, due to economical or technical grounds, are made with the same style and manner as the Crimean Bridge used to be commented. "A cartoon", "even Germans couldn't", all that bullshit. We have all heard that already.
    Such a giant project in any western country would cost 10x the real price, so that is why they yapping bout Russia being "unable".
    They are all missing - by purpose - that obvious fact.
    Considering the scale and progress of Russian infrastructure renewing, this would be just another huge project in the pipeline. Smaller to the ones already executed and in progress, in both financial and technical scale.

    That article you posted shows the solution FP... don't run the electricity back to the main grid as half of it would be wasted in transmission alone, though as an emergency backup once it is operational it is essentially a huge amount of free energy... look at the solar energy that hits the earth every day that is wasted because the surface of the planet is not covered in solar panels to collect it.

    They say use the electricity to generate hydrogen which can be stored or shipped around the world and sold.

    Separating hydrogen from oxygen in water uses electricity which in most places costs money and creates pollution.

    Using this electricity for this purpose is ideal, but of course you would also build a cluster of electricity intensive factories and companies to take advantage of the cheap electrical power.

    There are probably a lot of other industrial processes that use enormous amounts of electricity and it would be ideal to place them in the region of such a power generation station.

    Unlike a hydro electric dam you can scale it... you could start with a few generators and then add more over time.

    Improvements in efficiency in generator design means the later ones are likely to be more efficient than older ones so it probably would not be cost effective to start with a full capacity setup.

    I am sure the Jamestown thinktank will come up with articles showing some migratory fish population that will be devastated by this project but why start listening to them now?

    New technology in transferring electrical energy efficiently with less power lost would be very useful for Russia and a lot of other countries, and of course alternative methods of storing electricity would also be a valuable area of technology they could further investigate too.

    Once it is up and running everything could be electric including cars and trains and buses and aircraft....

    Russian 3D metal printers are becoming mainstream and world leading. Kalashnikov makes 5 coordinate NC machine tools
    that produce parts via laser melting of metal powders. That is like integrating a foundry into the finishing tool. All
    conventionally produced parts with molten metal poured into molds require additional processing with machine tools.

    Kalashnikov's machine tool can produce 300 kg parts and can hybridize their composition. So different metals can be
    used in different parts in almost any degree of complexity obtainable by laser powder melting. The properties of
    3D printer produced parts is on a higher plane than those that can be produced with old style techniques.

    Yandex technologies will translate any video on the Internet

    Online, July 16, 2021. Yandex showed a prototype of video machine translation. The new technology, which has no analogues in the world, will combine machine translation, biometrics, speech recognition and synthesis technologies. Thanks to it, Yandex Browser users will be able to watch videos in a foreign language with voice-over translation. You can see how the prototype works right now.

    "There is a lot of useful content on the Internet that is inaccessible to people due to the language barrier. And we are close to finally erasing all borders. Yandex Browser has been able to translate texts for a long time, this year it started translating images, and video translation is the next stage. This is a big challenge that no one in the world has solved yet. We are also at the beginning of the road, but we already have a prototype and an understanding of where to go next" – David Talbot, head of natural language processing at Yandex says. 

    The prototype only works with videos in English. Developers of the technology have already tested it on videos on various topics. Among them there are videos about climate change, machine learning, the history of Pluto and other equally interesting things. Users of the desktop Yandex Browser can view the video with voice-over translation here.

    Several teams worked on creating the prototype. Currently, it uses speech synthesis technology, Yandex.Translate developments, and biometrics. It allows you to determine the gender of the speaker and select the appropriate voice. And to make the voice-over match the picture, the translator pauses, slows down the speech somewhere, and speeds up the speech somewhere. The fact is that the original and translated lines often do not match in length, so a special algorithm monitors the pace of speech.

    Work on the prototype continues. Users will soon be able to choose which videos to translate using the new technology.

    A video demonstrating this technology:


    Yandex has implemented a truly revolutionary technology with huge potential. I also attach a video demonstrating the operation of this system, but it only works in the Yandex Browser and translates only from English to Russian. I am looking forward to the development of this technology

    Rostec put a video of a testing session of a Russian 5 axis overhead CNC milling machine manufactured by STAN, this was uploaded back in May but I didn't notice it anywhere.

    In the test session, they milled out a 100kg scale model of an Aurus vehicle.

    A few things to note, I looked at STAN's website and didn't find the model number present on their website, which is strange considering how many other paper machines exist on their website but not in metal, there's only a few that actually have real examples manufactured in their model line.

    STAN was always considered by those "in the know" in Russian machinery circles to be on the flaky side in terms of actually manufacturing local made products, as one of their big things was simply importing sanctioned tech through shell companies essentially and building machines for Russian industry through this.

    Though if Rostec put their weight behind this and put this on their website, then perhaps STAN got going in terms of making their own serious tech.

    This is extremely good for Russian industry, these machines are needed like air.

    MTS launches MTS GROM supercomputer. 

    PJSC MTS, a leading Russian digital, media and telecommunications services provider, announces the launch of the MTS GROM supercomputer, which has a performance of 2.26 petaflops, making it the third most powerful supercomputer in Russia.

    MTS will use MTS GROM to develop the digital ecosystem. On its basis, the MTS Artificial Intelligence Center plans to implement internal and external projects in the field of customer service and improving the operational efficiency of the business. The supercomputer will accelerate the creation and launch of products in the field of machine vision and industrial analytics, natural language processing, and intelligent video surveillance. Universities, large scientific and medical centers will be able to use MTS GROM in research related to modeling complex processes.

    A supercomputer plays a key role in training artificial intelligence algorithms. The computing power of MTS GROM allows you to create more complex models, test many times more hypotheses, and train neural networks dozens of times faster than before. This directly affects the quality of products developed by the MTS Artificial Intelligence Center and the speed of their launch to the market.

    In the future, MTS GROM's high-performance capacities will be available to Russian companies in the #CloudMTS provider's portfolio. This will allow large businesses to significantly reduce the time spent developing and implementing projects based on artificial intelligence and big data. For startups, reduce the cost of high-performance computing for speech analysis, video processing, and facial recognition by hundreds of times. For example, in fintech, MTS GROM resources can be used to develop remote identification solutions or to assess credit risks.

    The supercomputer is deployed by the cloud provider #CloudMTS in its own MTS data center based on the integrated NVIDIA DGX SuperPOD solution. This solution provides not only fast implementation of supercomputing systems, but also scalable performance for performing the most complex tasks of AI and high-performance computing.

    MTS GROM is the most powerful supercomputer not only in the Russian, but also in the European and American telecom. In the world ranking of high-performance cars, it ranks 241.

    "MTS is creating a digital ecosystem for Russian companies. Based on MTS GROM, we will develop the most promising technologies related to artificial intelligence, big data analysis and cloud solutions. The MTS GROM supercomputer is designed to increase the company's technological efficiency, as well as form the basis for future services that businesses and scientific organizations will be able to receive in the #CloudMTS cloud, significantly saving money" – Oleg Motovilov, Director of MTS cloud business said.

    About the MTS GROM supercomputer:

    The supercomputer allows you to massively run many parallel calculations at once on all computing nodes (servers). The solution is implemented on the basis of the NVIDIA DGX A100 hardware and software platform with NVIDIA A100 GPUs with a total memory of 320 GB.

    Computing nodes are connected by a high-speed Infiniband network. This is a switched computer network that is used in high-performance computing and has high bandwidth and low latency.

    The MTS GROM computing cluster is equipped with a NetApp data storage system based on NVMe technology, which provides ultra-fast interaction of computing nodes with the data storage system to reduce the training time of AI models.

    Russian-founded graphene nanotube leader valued at $2bn, inks investment agreement with Daikin

    OCSiAl, the Russian-founded global graphene nanotube leader, has inked an investment and business cooperation agreement with Japanese giant Daikin Industries.

    By East West Digital News in Moscow August 5, 2021

    OCSiAl, the Russian-founded global graphene nanotube leader, has inked an investment and business cooperation agreement with Japanese giant Daikin Industries. The companies disclosed OCSiAl’s valuation (“about $2bn”) but not the terms of the share subscription deal, reports East-West Digital News (EWDN).

    Pronounced ‘Oxial,’ OCSiAl refers to four chemical elements: oxygen (O), carbon (C), silicon (Si) and aluminum (Al). Touted as the world’s only manufacturer of graphene nanotubes at a large scale, this company is the brainchild of Russian physicist Mikhail Predtechenskiy and three businessmen — Yury Koropachinskiy, Oleg Kirillov and Yury Zelvenskiy.

    Having established their company in 2010 in Luxembourg, they garnered the support of several Russian investors, including Rusnano, the state-controlled nanotech giant ($60mn invested in 2012 and 2015); individual investor Igor Kim (2013, 2014); Moscow-based PE find Expo Capital (2019); and an undisclosed British investor (2019).

    In 2019 A&NN Investment — an investment holding controlled by oligarch Alexander Mamut — put $5mn to acquire 0.5% of OCSiAl, purchasing a fraction of Rusnano’s stake.

    Graphene nanotubes (also called single wall carbon nanotubes) are one-atom-thick graphene sheets rolled into tubes. Described for the first time by Japanese scientists, this high-performance material enables the creation of products with new properties. They are used for electrochemical power sources, elastomers, paints and coatings, composites and plastics. For example, OCSiAl says its nanotubes are used by all major Li-ion battery makers to develop cells for car manufacturers.

    Quasi global monopoly

    OCSiAl Group has more than 420 employees in facilities or offices in Europe, Russia, the USA, China, India, Japan, and South Korea. It claims a current annual production capacity of 80 metric tons, “accounting for 97% of the world’s graphene nanotube production capacity.”

    The company launched its first industrial-scale facility for graphene nanotube synthesis in 2013, and presented its commercial product, ’Tuball,’ in 2014. A second facility for graphene nanotube synthesis followed in Novosibirsk. The first stage of a new synthesis facility in Luxembourg is scheduled to start in 2024; then a new research center will be established in Novosibirsk. Under plans, this Siberian project will allow the company to increase fourfold its graphene nanotube production.

    OCSiAl and Daikin claim that their combined expertise and know-how “could result in a fundamental shift in the global industry.” The two companies will “develop, produce, and market graphene nanotube solutions for next-generation Li-ion batteries and fluoropolymers,” — which comprise a substantial part of Daikin’s business.

    “Graphene nanotubes demonstrate exceptional performance and definitive advantages over standard additives, opening-up new horizons for these applications,” the companies stated.

    Rosatom shows off a ProEXO passive exoskeleton, which are produced in the city of Vladimir (http://proexo.ru/)

    The girl in the vid puts it through its paces.
    She claims that the two 5-litre bottles feel like they weigh nothing when she picks them up, and she also managed to pick up a 20-kg tray that she couldn't manage without the exoskeleton

    Russian scientists have developed a multi-sensor chip for rapid monitoring of air quality. 

    Researchers of the St. Petersburg State Electrotechnical University (SPbGETU) "LETI" together with colleagues from the Saratov State Technical University named after Yu. A. Gagarin (SGTU) have created a unique chip that will allow you to diagnose the state of the environment, as well as control the emissions of pollutants into the atmosphere.

    Today, special attention is paid to monitoring the content of chemicals in the air. Analysis of the concentration of gases and various impurities in indoor and outdoor areas is necessary for monitoring the state of the environment, controlling the release of pollutants into the atmosphere, as well as for non-invasive diagnostics of respiratory diseases. Usually, special gas analysis systems are used to detect the level of air pollution — expensive and non-mobile.

    The joint development of scientists from St. Petersburg State Electrotechnical University "LETI" and Saratov State Technical University named after Yu.A. Gagarin will simplify the process of air diagnostics, make it faster and less expensive. Their invention-a multi-sensor chip weighing only 5 g-is related to the field of sensor technology and nanotechnology.

    According to Svetlana Nalimova, Associate Professor of the Department of Micro - and Nanoelectronics at St. Petersburg State Technical University "LETI", one of the creators of the chip, the main difference between their device is that it consists of several adsorption chemoresistive sensors, which allows you to detect the presence of several gases in the air. Existing analogues on the market are able to distinguish only one type of gas.

    "Using mathematical processing of signals coming from several sensors, gases are separated. In this invention, this is shown by the example of vapors of organic solvents-acetone, isopropyl alcohol and ethanol. Due to the fact that this invention uses hierarchical structures of zinc oxide in combination with mathematical processing of signals from a line of sensors, it becomes possible to detect and distinguish low gas concentrations, which is impossible to do with other devices in this price category" – she explains.

    Role of the scientific group of St. Petersburg State Technical University "LETI" under the leadership of Professor of the Department of Micro-and Nanoelectronics (MNE) Vyacheslav Moshnikov's role in developing a new method for manufacturing a gas-analytical multisensor chip was to prepare gas-sensitive layers for a multisensor device. They are based on hierarchical zinc structures, which have a larger area of the active surface of interaction with the gas of these structures. Due to it, the recorded resistance increases, which determines the presence of gases. This change makes it possible to determine the concentration of impurities in the air with greater accuracy. Scientists from SSTU, in turn, developed algorithms for processing signals from a line of sensors.

    "These developments did not come out of nowhere. Prior to this, Svetlana Nalimova's PhD thesis presented theoretical and experimental studies of the possibilities of improving sensory properties by forming sensitive layers with a fractal-percolation structure. Further, in the dissertation work of Anton Bobkov, methods of nanolithography with atomic-molecular design are introduced at the patent level — " says Vyacheslav Moshnikov. — "As a result, the new architectonics of gas-sensitive layers represents a hierarchy in which nanocrystalline rods form nanochannels with fractal-percolation geometry from the constituent nanocrystals. The patent for this invention was recognized as one of the best in the Russian Federation for 2018. The prospects for a multi-sensor chip as a whole are quite obvious-improving the selectivity and sensitivity of gas sensors."

    According to scientists, the development can find its place in environmental enterprises during environmental monitoring, in large-scale production when analyzing the state of indoor air, as well as in medical practice. In the future, it can be placed in a small portable device, which will make the equipment for monitoring air quality more mobile and less expensive.

    KRET also released air quality monitor/ disinfecting system on airplanes not long ago:
    https://rostec.ru/news/novaya-razrabotka-kret-pozvolit-obezzarazhivat-vozdukh-v-samoletakh/

    I wonder if they would incorporate this chip into later systems.

    This term is used by ignorant people.  Russia is the 5th economy in the world with a modern economy that is one of the most self-sufficient.  Just look at the import.  Of course, it is also an energy superpower.  Huge oil and gas deposits and infrastructure for their transmission.  The best nuclear technologies, etc.


    Russia is a gas station -energy economy , why you have doubt about it ?

    even the economic minister told it , that russia energy sales and services produce near 40%
    of the Russian budget.

    Russia economy is effectively a gas and energy station.. is an outdated economic model , that have not changed in decades . they do sell other things , food , mining and some weapons to india and others ,but the biggest industry in russia , that produce more for the russian budget by far are their energy and gas bussiness.

    russia have the same economic model of AFrica , the most basic form of business .

    is not an advanced business economy like US , taiwan or south korea ,that sells things , that nations all need for its own development and have no alternative to it.

    look how embarrasing is putin position ,that in the middle of sanctions , need to buy high tech to americans, still today ,  in order to build super computers.. if it wasn't by the anglo western economies ,.. and the asian high tech giants ,  russia will not have any technology at all , since even all their computers manufactured by taiwan ,use american and british tech .. no computers or internet t today , will not have smartphones , neither any advance computers ,. this is the russia vission of putin , a nation that 100% depends on their their adversaries technology ,for modernization of their business.  No

    and someone suggested Russia should sell electricity to japan and china.. No
    he is forgetting that japan is allied to US and if americans say no to japan ,they will obey and will not do any business with Russia. and china is pushing hard to become energy independent too ,and not depend neither in US ,neither on Russia.. so all this "super energy power" claims ,will be good for nothing. Russia will have a ton of energy ,and electricity , but will have no nation to sell it , since europe and china and moving away of their energy dependence and produce alternative sources of energy .

    Literally at least 50% of the words in every single sentence Vann posted is wrong and can be refuted with a single google search (even with the western sources), but I guess it's too hard for him anyway.

    Dude's stupidity is so great he might even get elected if he's in Poorkraine


    P/s Judging by his syntax, is he from Vietnam lol
