Xiaomi has released a new “smart outlet” model, Xiaomi MIJIA Smart Socket Bluetooth Gateway Edition, gagadjet.com reports.

On the body of the outlet there are two USB Type-A connectors for charging various gadgets. The main feature of the device is the function of the Bluetooth gateway. That is, using Bluetooth, the socket exchanges data with other gadgets and sends the received information via Wi-Fi.

As a result, the user can control devices from anywhere - the main thing is to have an Internet connection. You can also set a timer on the outlet.

The body of the device is made of heat resistant metal. If it heats up under heavy load, the user will receive a message about this. And at maximum temperature, the outlet will turn off automatically.

Xiaomi MIJIA Smart Socket Bluetooth Gateway Edition costs only $ 11. When sales begin - is still unknown.

Must save from floods: in China, a 500-meter protective wall was printed on a 3D printer (video)

Posted by: Katerina Andriyuk

In the Chinese city of Suzhou, they created a giant wall using a 3D printer. Winsun has completed the 500-meter wall, which is supposed to protect residents from flooding.

A large-scale design was made of individual parts, but if assembled, it will be considered the largest object printed on a 3D printer in history.

The main task of the wall is to absorb the energy of the waves. The design is able to protect the coastline from the effects of water during floods.

Typically, buildings are used to improve canals and rivers to protect land from erosion. Facing walls often require the development of individual bricks and dams, therefore, they are considered extremely expensive and complex projects.

By the way, the creators reported that their design turned out to be much cheaper and did not affect the coastline in any way, which is almost impossible during the construction of facing walls.

 

Also, scientists from the United States also recently presented their brainchild - a titanium wheel created using 3D printing technology.

The wheel was printed using a unique 3D-printing technology, which allows not to throw out the remaining materials and resources, but to use them in further production. HRE Wheels from California and GE Additive AddWorks have joined forces in developing this unique wheel.

The wheel was made of titanium alloy, where most of the work was done through an improved type of 3D printer. This technology is called 3D printing.

The team of composers, musicologists and IT specialists has been working on the project for several months now. First, the algorithm they created analyzed all of Beethoven’s works. Then the AI gave fragments of the 10th symphony so that he could finish writing its missing parts based on everything else.

The algorithm already even issued several trial options, but the music turned out to be too "computerized," scientists say. The symphony will be ready by April 2020, to the 250th anniversary of the composer.

This is not the first time that they are trying to restore the 10th symphony. Beethoven's art researcher Barry Cooper, who found the sketches of the work, published his own version of the melody, but musicologists did not appreciate it. Scientists hope that AI will do better than humans in this matter.

While the release of large volumes of carbon dioxide into the atmosphere continues, some experts and researchers are trying to find the most rational and effective way to get rid of this harmful compound. So, experts from the Massachusetts Institute of Technology have found a new field of application for large reserves of carbon dioxide in the atmosphere - namely, the creation of a new type of battery based on lithium dioxide and carbon. In principle, the idea is interesting and quite feasible, because carbon dioxide is a fairly flexible compound from the point of view of chemistry, but it needs a certain catalyst to start the reaction with lithium.

And as such a catalyst, experts decided to use a carbon electrode. But first, they preliminarily prepared carbon dioxide for conversion into a full-fledged energy source for the battery. This process involves the reactivation of carbon dioxide in an amine solution, into which a liquid electrolyte with a carbon electrode is then added. Experts emphasize that this is the whole unusual battery, since the combination of liquid and solid electrolyte is an extremely unusual concept that has not previously worked.

But thanks to the use of carbon as an electrode and a lithium anode, a rather high-energy chemical reaction is obtained, which starts the properties of the catalyst for carbon dioxide in the electrode. As a result, experts were able to achieve a fairly stable chemical reaction between carbon dioxide and lithium, which was expressed in an excellent battery. In addition, they finalized the formula in such a way that when discharged, the battery converts the residual carbon dioxide into a solid carbon mineral.

This mineral, firstly, can later be used in similar batteries as an additional power source, and can be destroyed much more easily than carbon dioxide in the atmosphere in case of need. The comprehensive development of specialists from MIT is still at the concept stage and is only an approximate vision of how to convert carbon dioxide into something like a battery.

At the Indiegogo Collective Financing Facility, the new X One electric bike has arrived.

The bike is controlled using the application on the smartphone. On the frame of the device there is a special mount in which the smartphone is placed. Thanks to the owner’s authentication by face, a third-party will not be able to use the bike.

 

The smartphone can also be used to control various functions of the bike using voice commands, and turn signals are turned on by tilting the head to the corresponding side.

The X One frame is designed from composite materials, due to which the bike weighs from 20 to 24 kg. The lights are activated thanks to the light sensor.

The battery is removable, it charges in just 2.5 hours. Its charge is enough to provide 75 km of track at a speed of 45 km / h. It is noted that during riding from a hill, under a hill or during braking, energy is generated, due to which an increase in the course of the bicycle is provided.

The price of X One starts at $ 1999 for the basic version and reaches $ 2199 for the most powerful modification. In retail, a bike will cost between $ 3,999 and $ 4,399.
