While China is preparing to restart its stalled nuclear program after a three-year moratorium, scientists from the Laboratory of Hefei District are instead engaged in nuclear fusion instead of grossly splitting atoms, dreaming of "putting the Sun in a box."
China has already spent about $ 900 million building a tokamak, which turns hydrogen isotopes into a plasma, fusing them together and releasing energy. Sun Yuntao, deputy director of the Institute of Plasma Physics at the Hefei Institute of Physics, said that despite the technological difficulties, the project received another funding of the same amount, and new construction plans are already being developed, Reuters writes.
“In five years we will start building a thermonuclear reactor. It will take another 10 years, after which we will construct a generator and start generating energy by about 2040, ”he said.
Although thermonuclear energy can make a revolution in the energy sector, until now, engineers have not been able to achieve an economically viable technology in which the energy output would exceed the costs. As skeptics express, fusion technology seems achievable 50 years later, as it was half a century ago.
China has been studying the synthesis reaction since 1958, but at this stage it is still a question of international cooperation, rather than competition, said Sun. In particular, the People's Republic of China participates in the ITER project and is responsible for creating 9% of the components of this reactor, which, according to the plan, should start producing the first plasma in 2025.

Xiaomi has developed a new model of electric bike.
This is the second version and it is called HIMO C20, reports infocar portal. If the first bike was offered at a price of 260 dollars, then the new one costs already 375 dollars.
The model has a twenty-inch frame, a trip computer on the steering wheel with an indicator of speed, mileage and charge level. The new items from Xiaomi range of eighty kilometers. Also, the new lithium-ion battery, which weighs two and a half kilograms. He charged in six hours.
Three modes of operation are available - only on the electric, with an electric motor as an assistant or just on the pedals without the participation of an electric motor.
The total weight is twenty-one kilograms. It develops a maximum speed of up to twenty-five kilometers per hour. Its length is about one and a half meters, and its width is 610.
The HIMO C20 also has a handy portable pump hidden in the seat, as well as an LED flashlight. The bike itself is foldable, foldable. He has a folding steering wheel and pedals, which makes it even more convenient to transport it in transport.
The Xiaomi device will open the car even if it is thoroughly wet.
It can be used both in cars and in a motorcycle.
Xiaomi is preparing to supplement the range of solutions of the branded collective financing platform with a new product - a car lock with an integrated fingerprint scanner.

Judging by the picture, such a lock will regularly cope with its capabilities even if it is thoroughly wet. The Chinese castle Mars Exploration Technology, founded in May 2015, is behind this castle. She is engaged in industrial design and development of a wide variety of devices, from drones to virtual reality helmets.
There are already similar solutions on the market, their cost is on average $ 340. An analogue of Xiaomi should be no more expensive and at least not worse in terms of functionality. The device must officially submit on April 9th.
Also, Xiaomi plans this year to release a new firmware MIUI 11 for their Mi and Redmi smartphones. This firmware will be available for more than 40 models. But for some smartphones update will not be available due to outdated hardware.
According to the manufacturer of smartphones, their technical equipment does not allow for full-fledged work on new firmware. Thus, MIUI 11 will not receive the following seven models of Xiaomi Redmi Note, 3S, 3X, 4, 4A, Pro.
And the owners of the above smartphones should be prepared for the fact that soon the new software for their devices will cease to be released, including patches for the security system from Google.

OpenAI, a research organization in artificial intelligence, can claim to be in the first place in the world: its AI system, trained to play the complex strategic game Dota 2, has surpassed the world champion team in eSports. Reported by The Verge. The OpenAI Five Finals competition was held April 13 in San Francisco.
The top five Dota 2 professionals from the OG team, which won the eSports prize last year - $ 25 million, won first place in the international Dota 2 tournament. OG met in the "best of three" competition with five OpenAI bots. All of them were trained using the same deep learning methods with reinforcement and independently controlled by different levels of the same system.
Reinforcement training is a method of trial and error for self-improvement, in which the AI enters the gaming environment with a zero understanding of how the game works and intensively trains using reward systems and other incentive mechanisms.
"OpenAI Five is based on deep learning, which means that we programmed AI for learning and not for the game. In 10 months of existence, he has already played 45,000 years in Dota 2," said co-founder and chairman of OpenAI, Greg Brockman.
In the first match of the day, OpenAI Five surprised OG with its victory, based on a number of aggressive tactics, including a kind of decision to spend the earned game currency to instantly revive the heroes after death, even at the beginning of the match. As noted by Greg Brockman, OpenAI loves strategies that contribute to short-term profit by identifying weaknesses in long-term planning. In this match, this tactic paid off and OpenAI Five got an advantage, which OG simply could not overcome, because the match was delayed to 30 minutes.

For OpenAI, the victory here is evidence that the reinforced learning approach and the general philosophy about AI are successful. The research team will no longer hold public demonstrations of its AI-bot, now it is developing software that will allow people to collaborate with the OpenAI Five in real time, playing in a team with bots and learning from them unusual, unprecedented strategies and behaviors. The organization also introduced a platform for the game against OpenAI Five - Arena.

OpenAI states that collaboration software may not be publicly available. But, according to Sam Altman, co-founder and CEO of OpenAI, this type of work suggests that working with AI agents can lead to huge benefits in the future.
"This is an important lesson about how the world will work and teach such things. Cooperation is one of the most positive ideas about the future of the world - AI works together with people to make people better, to bring them more pleasure and influence," says Altman .
OpenAI will continue to play Dota 2 and other games, primarily because they are good test sites for artificial intelligence and tools for performance testing. As Altman argues, there is probably no video game now that a system like the OpenAI Five would not have been able to master at a level that exceeds human capabilities.
"OpenAI is trying to create a common artificial intelligence and share these benefits with the world, ensuring its security," commented Altman, referring to the desire to implement a multi-purpose AI system capable of performing any task that a person can perform.

Today, getting from point A to point B is not so difficult. Even if you do not know the city or area - one of the many navigation systems or the same maps from Google will tell you the way. Now imagine a situation in which, for sure, many turned out to be: you got to the destination, enter the building and ... get lost. Where to go? Where is my office / store / department? It is quite possible that such situations will soon be avoided, because the US company is developing a technology for mapping and indoor navigation based on augmented reality (AR).
It is worth noting that Apple already promised something similar to us. Only here the Cupertini built their system on iBeacon devices that need to be installed. Immediately, no "beacons" are needed. Only a smartphone is needed.
Everything works quite simply: the technology is integrated into the internal maps of the premises. Thanks to this, she can find out where the user is at the moment, and then show the right directions on the smartphone screen. To do this, use the camera of the device, which "removes" the room, and the path is projected on the screen in real time. In fact, this is very similar to the AR mode in Google Maps, except that it is intended for indoor use and not for street navigation.
The development is called Dent Reality and the software part relies on both GPS data and special algorithms for determining the position of the user. Algorithms include methods for measuring distance, recognizing objects inside a building, and options for displaying a virtual path with incredible accuracy.
Moreover, the program is based on an open SDK, so third-party developers can make their own improvements in it, as well as use the software part to develop their products of a similar theme. In addition, the developers have opened access to the materials on the basis of which the algorithms were built.
At the moment, the technology looks very promising, but it is at a very early stage and still far from release. However, if the developers and their partners succeed, we will get a very convenient tool for orientation in unfamiliar rooms.
