The new development of Alphabet X will connect rural areas of India to the Internet

New development of Alphabet X will allow to connect rural areas of India to the Internet – high-tech and advanced news on

The Alphabet division under the stamp X developed the technology of Free Space Optical Communications (FSOC), a new type of optics, thanks to which it is possible to connect large rural regions to the Internet.

Now Alphabet signed a contract with the Indian state of Andhra Pradesh, within which the state purchased 2,000 FCOS devices. They are small boxes that are attached to poles with mobile Wi-Fi points, and then communicate with each other using light rays, providing an Internet coverage area with a speed of up to 25 Mbps for citizens and up to 100 Mbps for enterprises and organizations.

Now only 20 percent of the inhabitants of the Indian state have access to the Internet, whereas by 2019 local authorities expect to connect to the Network an additional 12 million new users, among which there will be not only private individuals, but also enterprises with organizations.

FSOC technology was used by Alphabet engineers and earlier in the Project Loon project – then it was planned to distribute the Internet using special balloons equipped with FCOS devices.

The installation of FSOC on poles is much cheaper than balloon launches, the effect is just as good, so the Alphabet engineers team will soon arrive in India to implement the project.

Microsoft is trying to breathe life into the search engine Bing with the help of artificial intelligence

It's unlikely that many of our readers will use the Bing search engine as the main source of the information sought. Surely there are such people, but their overwhelming minority. Most of the users of Runet prefer to systems such as Google and Yandex. Microsoft Corporation, however, does not give up, and constantly develops Bing, introducing new features into it. For example, yesterday it became known that now he will actively use artificial intelligence to search for information.

As part of the event that was held yesterday in San Francisco, Microsoft officials announced that Bing will henceforth actively use the capabilities of advanced artificial intelligence when processing users' search queries. For example, when he answers the question, he will first find the answer immediately on several sites, and then he will choose the most popular option. If the answers differ, Bing will try to provide the user with a choice of the most popular versions, so that he can choose the option that best suits him.

The answers to queries will now be presented in the most accessible and understandable form, so that a person could read them comfortably . Microsoft employees themselves gave this example: instead of answering that the area of ​​Syria is 71,489 square miles, Bing will compare its area to the US state of Florida. Of course, this is an analogy, but Microsoft representatives, of course, know better. They insist that they do not want to load people with numbers, but instead offer them a more vivid answer, which they will immediately understand.

The search engine will also improve its skills in comparing different concepts and phenomena. Want to know the difference between Pilates and yoga? No problems. Bing will detail the pros and cons of these two systems of exercises in the most accessible form. Among other things, the search engine will begin to ask leading questions to clarify what exactly interests the user. Well, the most important achievement is that Microsoft engineers consider a new search for images. Bing has learned to recognize objects in photos and search for them on the Web. For example, a girl wants a handbag like a movie star – the search engine will process the photo from the red carpet and immediately give out the name of the product and the link to the store.

Microsoft also announced its collaboration with the popular Reddit forum. From now on Bing will be able to search for information among the millions of topics of this resource and to provide search results to users. You can search even among the most popular recent AMA interviews (Ask Me Anything), when users of Reddit ask any questions entered by the celebrity forum. In addition to Bing, the advantages of artificial intelligence will also include a voice assistant Cortana and office suite Office 365. All of the above will be available to users within the next month.

Prototype truck Tesla Semi was seen on the road

It so happened that the new Tesla cars begin to "accidentally" appear on the road after some time after the presentation. Before that, someone periodically skated on the brand-new Model S, which had not yet left on the conveyor belt, now it was the turn of the Tesla Semi truck, which was filmed in broad daylight on the usual municipal road.

Thanks to the attentive operator, who was very close to the design- the center of Tesla, past which an electric truck was traveling along the road, we will be able to consider the novelty in more detail, making the most complete picture of what a cargo electric car from Ilona Mask will look like.

The video clearly shows that the rear the cabin has no compartments and placed in a niche of her equipment. Apparently, the battery, as well as its passenger cars, is really located in the bottom of the truck. Apparently, the well-established scheme of installing and disassembling the batteries best allows you to replace it with this arrangement of batteries, and the weight, it seems, distributes this position better.

According to the information published by the developers, the battery capacity of Tesla Semi is about 1 MW-h – a fairly large battery, which because of its weight and dimensions is really difficult to install along the chassis or hang on the car's cab .

Mass production of an electric truck in Tesla is planned to begin in two years. After the presentation, the number of pre-orders for Tesla Semi began to grow slowly but surely – several large orders for trucks came from Wallmart, Sysco and Anheuser-Busch. Companies are actively advocating for the protection of the environment, so they plan to purchase small lots of Tesla trucks to reduce the number of harmful emissions.

Blue Origin launches new modification of the New Shepard missile

Private space company Blue Origin returned to launching missiles after almost a year's interruption and successfully launched the New Shepard rocket, and then successfully landed a capsule for the crew. The suborbital launch vehicle was launched from a company-owned launch pad in West Texas, reports the port of The Verge, citing company representatives.

For almost the entire year of 2017, the company was not very active and rarely found headlines in the media, at least for compared with previous years. In 2015, Blue Origin became the first private company to carry out the vertical landing of the rocket after its launch. After that, a total of 5 launches were made, and all of them were successful. In the latter, held in October 2016, despite its own expectations, Blue Origin also carried out everything at the highest level and gently planted the spent first stage.

Today the company launched a new modification of the New Shepard missile, which is more similar to that final version A missile that will deliver tourists to space. For example, a new capsule for the future rocket crew now has portholes, while the previous versions used fake painted pictures in the form of windows.

Earlier, Blue Origin CEO Bob Smith said that the company is aiming for the first commercial tourist launch by early 2019, but before that, a private space company is going to conduct several pilot manned flights. According to Jeff Bezos, owner of Blue Origin, billionaire, these manned flights will take place next year, which is somewhat later than previously scheduled.

Western media note that it is not yet clear how these launches are going to be held – open or closed. In the end, Blue Origin all this time is not very actively covered all the previous starts, celebrating them only in "Twitter", and after publishing a video.

Jeff Bezos himself reported on the successful launch of the new modification of the missile in "Twitter" himself, who wrote:

"The NewShepard rocket with the new capsule Crew Capsule 2.0 successfully carried out the first flight. The new capsule is equipped with windows. On board was a test doll. The train was great. "

… and who accompanied the video recording:

The New Shepard missile is planned to be used in tourist launches to the border of outer space. The entire flight will take place within 11 minutes, within which those who paid for the ticket can enjoy the views of the Earth and experience all the delights of weightlessness for about 3 minutes. After that, the capsule will descend back on parachutes, and the first stage of the rocket will be gently planted on a special pad and then prepare for a new launch.

Is it possible to turn the desert of the Sahara into a giant solar battery?

In 1986, a surge in voltage during the security check at the Chernobyl reactor caused a catastrophic explosion. Thirty-one people died on the spot, even more died due to the consequences of the release. Along with the Fukushima accident in 2011, this is one of the two worst nuclear accidents, which are marked by a maximum severity level of 7. Support for nuclear power has fallen sharply around the world precisely because of these events.

But Gerhard Nies, the particle physicist from Germany, decided to ask a simple question. Fossil fuels such as coal, oil and natural gas have come a long way before becoming our energy source, and partly due to our energy supply to the sun. Plants and animals buried under the earth, for thousands of years turned into this fossil fuel. Radioactive uranium, which feeds nuclear power plants, has also become a by-product of nuclear fusion in the stars. Will not it be cheaper, simpler and cleaner to get energy from the sun directly?

Nisus made a simple calculation and found out that in six hours the world's deserts receive more solar energy than the entire human race consumes for the year. The energy needs of the world can be met by covering only 1.2% of the Sahara desert with solar batteries. Nis probably did not even think about carbon dioxide emissions – because once fossil fuels would end one day – but climate change fueled the motivation to engage in such a project. And, of course, all this looks very simple: Nisus himself was amazed, are we really so stupid as to pretend that they have not come to this yet?

Of course, it's difficult to persuade people to invest in such a grandiose and ambitious scheme – and which requires huge investments that do not promise any serious profit – but Desertec's initiative was a real attempt to demonstrate the concept's working capacity.

The plan was to place solar panels in the Sahara that would provide most of the facilities in the Middle East and in North Africa, and will also provide energy exports worth $ 60 billion, which will satisfy 15% of the electricity demand in Europe. Meanwhile, Europeans – importing the energy of the desert – could save up to 30 euros per MWh on electricity bills. All will win in the long run.

The Desertec project began to develop in 2009 and soon acquired a number of industry partners, including EON, Deutsche Bank and Siemens. Their investments were necessary, since the project was estimated at 400 billion euros – although in a few years of work, it would already pay for itself. However, the project was stalled, and by 2014, only three of the seventeen original partners of the industry remained.

What happened to Desertec? This is due to two sets of factors. First, these are problems that have for many years pursued the transition to renewable energy sources. Secondly, these are unique geopolitical and logistical problems of solar batteries in the Sahara. Both deserve attention.

Reduction of gaps

The first is the common problems of renewable energy. The Desertec plan implied the creation of a centralized power station that would distribute electricity to three continents, and transferring this electricity to such long distances could be a problem.

The plan was to use high-voltage DC transmission lines – instead of AC lines, to which we are accustomed . At great distances, energy loss can be as low as 3% per 1000 km, which is much less than in the case of alternating current. But nothing of this magnitude was built before; The biggest chain is in Brazil, it's the line of Rio Madeira, which transmits 6.3 GW to 2,400 kilometers. To Desertec was successful, from the Sahara to Europe it is necessary to transfer 30 GW of energy over a distance of more than 3000 kilometers. And yet, it can be quite realistic on the news that in July 2016 China started financing a high-voltage DC transmission line that will transmit 12 GW to 3000 km.

And it's not just about transferring energy. What to do when the sun is not in the sky? But this is a serious problem for renewable energy sources.

Energy storage can be part of the solution, but not yet developed enough. In the global repository, hydroelectricity is currently dominated by pumping. This simple technique defines 99% of the world's storage, but with global storage of 127 GW, it is still less than 1% of the total power used by the world. Researchers in the energy industry are talking about a hypothetical "European supernet", which will allow the transfer of power from regions of excess production to regions of excess consumption. The same is happening within countries to ensure a continuous supply of electricity, but this is largely due to the fact that the production of fossil fuel energy can be increased or decreased.

And there are precedents for such a system: France and the UK are connected by a power line in 2 GW. High-voltage direct current allows to transfer energy in both directions, depending on demand; usually the British import French electricity, but not always. The fjords of Norway allow producing 98% of its electricity in hydroelectric power stations; the winds in Denmark make it possible to produce 50% of own electricity from renewable sources of energy; Cables coming through Scandinavia guarantee that everyone can get energy if the wind blows or the sun shines. Studies have shown that the Mediterranean region with an energy source like Desertec can provide 80% of its own energy needs through solar alone, without worrying about interruptions.

Expect the unexpected

While people were considering a project that could focus the world's energy supply in Libya and Algeria, more specific problems arose – civil war in Libya and political instability in the Sahara. Add to this the fact that the project was planned to be completed only by 2050, and industrial partners would have to be convinced only by promises of short-term gains.

There is a more subtle political problem of the rights to natural resources.

As with many courageous, futuristic projects, little government intervention can prevent a project like Desertec. Countries have benefited from the export of oil or coal; Can sunlight play a similar role once? At first glance, this is another bonus in the Desertec scheme; the poor countries of Africa would be extremely valuable by exporting energy to the world, while providing their own needs. But in practice, another imperialist exploitation will begin. This is only a new form of exploitation of resources, and history remembers a lot of sad stories on this topic.

There is another reason for stopping the development of Desertec.

The project supported concentrated solar energy in which parabolic mirrors concentrated sunlight that boiled water that set in motion wind turbines. This technology allowed to attract to the project Siemens. The problem is that when Desertec began to develop, the price of solar batteries began to fall precipitously. From 2009 to 2014, the cost of photovoltaic cells fell by 78% and continues to fall. In just five years, photovoltaic cells went down five times. Therefore, Siemens left the project.

Desertec continues to live in small forms; The construction of power stations in Morocco is continuing, which will allow meeting the local demand for energy in the country. Perhaps, it is worth starting with this: to increase own production in the countries of the Middle East and North Africa. In the end, this is not the first and not the last project, which promised to provide the world with boundless energy and which has reached a deadlock; historians remember the "Atlantropus" – a plan to block the Strait of Gibraltar and use it for hydropower, which was of great interest in the 1920s.

Still, the prospect remains too tempting. The solar energy that could be extracted in the world's deserts is just one of the few possible ways to tap renewable energy sources to meet the needs of people on a large scale. One day we will be much more effective in using what the sun gives us. We will have to.

How to sail without Nicehash? Instruction, links and illustrations – high-tech and advanced news on

For several days Nicehash has been hacked, and we only talked about how to mine with it. Therefore, we correct and tell about the alternative method of mining on video cards.

Nicehash was not an ideal, but very convenient crypto currency mining ministry: download the application, drive in a purse, press "START" and receive payments in Bitcoins without unnecessary fuss about how it all works. Now we will try to do without it.

  • 1. We register on the exchange Bittrex . If there are any difficulties, we look at the instruction from our friends
  • 2. We go to the Wallets tab, then in the search we write "ETC" without quotes. Look for the found Ethereum Classic and press +. We copy the received ETC address into any text document and save it – a bit later we will need it.
  • 3. We go to the section Lab -> Auto-Sell
  • 4. In the search, we again write "ETC" without quotes and press Enter. The system finds Ethereum Classic. Click on the button "Enable Auto-Sell" opposite to it.
  • 5. We go to section of support of mining-pool ETC . Download the archive with the latest version of the Miner Claymore .
  • 6. Unpack on the computer, look for the file etc-pool.bat and open it in notepad. Then change the purse address to your own, which we saved in the second paragraph in a separate file. If anything, the address is after -ewal. We close, save and exit.
  • 7. We press twice on etc-pool.bat, after which the mining should begin. Sometimes Windows prevents the launch of files with the extension .bat – in this case you need to allow the alarm system to start the security system, then start the "batch file" again.
  • 8. After a few minutes, you can go to page statistics pool, where in the upper right corner to drive your wallet from point 2 and click search and see the statistics of your farm. if the video card is one, you need to wait a little longer, because alone it works very slowly, where it slowly looks for solutions and sends them to the pool.
  • 9. Every few days we go to Bittrex in the Wallets section, write in the BTC search and check our balance, which is listed opposite the word "Bitcoin". Did you collect enough money? We deduce it on your local wallet!

This instruction allows you to run the mining of any coin, Ethereum Classic, we took for example, since we personally like it more.

How exactly does the AI ​​make decisions? Scientists have stopped understanding this

Speakers at the Neural Information Processing Systems conference, experts in the field of artificial intelligence said that they ceased to understand the decision-making principle that guided AI, – said Quartz. According to experts, taking for granted the actions of AI without understanding its logic is quite frivolous, because people need to adopt machine learning models, they need to know what exactly AI is guided by when deciding how exactly it should act in a particular situation.

Often, decisions made by AI are biased, in addition, its associative "thinking" is also often not so ideal, as a result of which AI conducts incorrect analogies. Such mistakes can be costly if AI controls complex projects, such as flying to Mars. In this case, an incorrect act of artificial intelligence can not only destroy expensive equipment, but also lead to the death of people. Therefore, before allowing AI to make important decisions on its own, it is first necessary to learn the principles that guide it, "explains Metra Raghu, an AI expert from Google.

At the conference, she presented a report describing the process of tracking the actions of individual parts neroset. Viewing them in parts, you can understand the logic of AI, and then, in which case, it and correct it. Analyzing millions of operations, she was able to identify individual artificially "neurons" that focused on misconceptions, and then disable them, making AI more compliant and correct.

It's something like a teacher submitting some material, and then asks the student to tell in his own words what he understood from the lecture, "explains Kiri Wagstaff, an AI expert from NASA.

Judging by the results of this research, it is not so difficult to understand correctly the actions of an artificial intelligence. The main thing is to solve the problem before it becomes too late.
