A special thermal battery will help solar stations generate energy at night. In addition, it will provide an opportunity to store electricity.
Thermal Battery, United Sun Systems, ITP Thermal, Solar Energy
It is reported Sotsportal with reference to Hightech.
- The thermal battery was developed by specialists from Curtin University and international companies United Sun Systems and ITP Thermal as part of a project to create a system of concentrated solar energy, which requires a battery. It provides an opportunity to store energy and give it away at any time of the day, seven days a week, writes Phys.org. The ultimate goal of the project is the development of a new technology that integrates the thermochemical energy storage into the parabolic Stirling concentrator. This technology produces up to 46 kW of energy and is ideal for remotely located industrial enterprises, such as mines, because it provides them with the right amount of electricity on demand. Depending on your needs, you can install several parabolic plates.
A thermal battery developed by a team of Australian scientists will become part of this power grid. It accumulates heat in the metal, and gaseous hydrogen or carbon dioxide is used as the coolant. At night, or when it is overcast, hydrogen or carbon dioxide from the tank is absorbed by the warmer metal, forming a metal hydride or carbonate that releases heat. Then heat is converted into electricity using a thermogenerator.
“Energy storage has always been a stumbling block for renewable energy, but our prototype thermal battery can store and, if necessary, give off solar energy regardless of sunlight,” explained Professor Craig Buckley, project manager.

The so-called soft robotics, based on the use of flexible polymeric materials, has a really impressive list of technical advantages in comparison with traditional robotics - that is why so much money and time is spent on its development and improvement. So the team of specialists in robotics from the Massachusetts Institute of Technology decided to contribute to this development, presenting today a unique version of artificial muscles based on the use of special complex polymer coils-beams that change their shape depending on the effect of a particular temperature spectrum.
More specifically, the new development is a slightly reworked type of artificial muscles for robots, which is based on the use of special coils-wires composed of cyclic copolymers and elastomers, as well as thermoplastic polyethylene, which in total gives a material with unique properties. Material that can autonomously and without any third-party control adapt in its form depending on where it is affected by a source of low or high temperature.
In some ways, the new format of artificial muscles resembles the internal structure of a cucumber, because here and there the principle of enveloping with the processes of the main structure is used - which in this case consists of a mix of polymers. Whatever it was, at this point in time, scientists continue to test their new development, which promises to be really decisive in the near future in the field of applied robotics. Especially considering the fact that for them this is the first experience.
Soft robotics, which could use such a format of artificial muscles, could become even more complex and interesting in terms of selecting additional tools and segments of their application - that is why the team from MIT continues to actively engage in experiments and experiments to make these artificial muscles more elastic. because she wants them to find application in a wide variety of ways.

Controllers from Xbox One, without a doubt, are the most convenient gamepads for computers and consoles, but for mobile devices they are not the best fit. Yes, there are a lot of custom mounts on the market, but often this solution is not the most practical one. Microsoft is well aware of this and is actively experimenting with various gamepads for mobile devices and tablets. Last year, information appeared about the project of the Microsoft research division, in which the company designed a gamepad capable of being divided into two parts for fastening on both sides of a smartphone or tablet. Although the gamepad itself has not yet come true, Microsoft received a patent for this idea. The schemes described in the patent look exactly the same as in the documentation published in October last year.

We all know well that having a patent does not mean that the device will definitely be on sale, but it would be very nice to see such a gamepad on the market. Xbox One controllers are already natively supported on Android and iOS (in the fall with the release of iOS 13), which means they can be used to work with Project xCloud. Getting out of a gamepad specifically oriented to mobile devices with more ergonomic fixings and functions would be a far more convenient solution than using third-party mounts for existing gamepads. The controller for mobile devices looks like a logical and even demanded product from Microsoft, which in the near future plans to transfer its console and PC games to mobile devices via Project xCloud. We'll see what the company offers its users in the near future.

Today, a talented team of robotics from the Higher Polytechnic School in Lausanne, Switzerland, presented their new unique brainchild, namely a group of small robots called Tribots, which are really mini-robots with many useful sensors and functions. In essence, development is something like an artificial ant colony that can cope with various tasks within a single information transfer system between individual robots - as was demonstrated during the preliminary testing of Tribots robots, where experts also indicated their ability to move efficiently. on any surface.
At the same time, small robots perfectly avoid obstacles in their path, forming something like a virtual map of the object-obstacle that stands in front of them - thus, they can effectively find out what kind of obstacle they need to overcome. Moreover, the robots are composed in a very convenient three-legged format and, in their design, really resemble ants during movement.
The fact is that they move and carry out different patterns of movement in much the same way as an ant does - for example, if they need to jump over an obstacle, they close the upper part of the legs and thereby make a jumping movement. The robots were called Tribots, because they have three protruding micro-limbs, each of which is controlled in a separate way - so that the robot can effectively move even on the most problematic areas of the surface. It is worth noting the fact that robots are completely autonomous and do not have a wired connection.
All this allows a potential user to use the potential of the Tribots robots to organize a more complex and multi-purpose robotics system - for example, when it is necessary to cope with the development of some particularly complex ways of movement. However, the Swiss specialists do not limit the scope of their development exclusively to the creation of separate systems of robotic movement and see for them a really wide field of subsequent use.

“Over the past two decades, AI systems have mastered more and more complex forms of poker. However, all previous breakthroughs were limited to the participation of only two players, ”said the publication.
Compared to the paired games, games with a large number of players caused difficulties for the AI. To overcome their scientists have equipped the system with "abstract action" and "abstract information." These properties are needed to help the system reduce the number of options and highlight those needed to make a decision.
To do this, experts have developed a program called Pluribus, which has learned to play Texas Hold'em with its five copies. Playing time after time at random, Pluribus gradually determined which actions and with what probability gave the best results. Analyzing this data, the system gradually improved its strategy.
The self-learning method was previously used in zero-sum games for two, such as backgammon, Dota 2, Starcraft 2, and doubles poker. But as experts note, the algorithms used there differed significantly from Pluribus.
How did the experiment go
The computer game was evaluated in two formats: five players against Pluribus and one player against five copies of Pluribus.
Each of those who took part in the experiment earned more than $ 1 million at poker. The participants were players Jimmy Chow, Seth Davis, Michael Galliano, Anthony Gregg, Dong Kim, Jason Les, Linus Leliger, Daniel McAuley, Greg Merson, Nicholas Petrangelo, Shaun Ruan, Trevor Savage, Jacob Thule.
Every day, five professionals were selected for the game. However, they did not know the other participants. Each person was given a pseudonym, which remained unchanged throughout the experiment. It was possible to track the progress of the players. Between people, $ 50 thousand was divided to motivate them to play with full dedication. The players were guaranteed at least $ 0.40 per hand. The amount could increase to $ 1.60 per hand, depending on the outcome of the game.
In a match with five professional poker players or with five copies of Pluribus playing against one player, the AI for the 12 days of the experiment showed the best results in more than 10 thousand hands.
