And no Hyperloop is needed. China showed a prototype of a train designed to travel at a speed of 620 km / h

While the topic of Hyperloop vacuum trains has subsided considerably in the past couple of years, a prototype of a train was shown in China, which is designed to travel at speeds up to 620 km / h, and at the same time, the creators are working on increasing it to 800 km / h, and this is already very close to estimated speeds for Hyperloop.

The prototype was created by scientists at Southwestern Jiaotong University. The development is based on the technology of magnetic levitation, which makes the novelty similar to the maglev. However, Chinese technology is supposedly much cheaper and more efficient. In particular, according to the calculations of scientists, about 39-46 million dollars are needed to build one kilometer of such a track, compared to about 31 million in the case of a conventional high-speed railway. As for the prospects, the creators of the prototype say that the technology can become commercial in six years.

Compared to the Maglev, the new train has another advantage: it can start levitating immediately, and not after gaining a certain speed. The use of liquid nitrogen versus liquid helium in Japanese maglev trains provides energy efficiency and lower cost. In the latter case, the temperature of helium should be -269 degrees, and for liquid nitrogen such a low temperature is not required.

One of the problems that scientists have to solve is the high noise level. At such high speeds, it is much more difficult to fight it than in any ordinary train.

Considering China’s plans to build high-speed transport routes in its country, it is quite possible that in 10 years, trains capable of traveling at speeds above 600 or even 800 km / h will really become a reality without any vacuum tunnels.

One of the largest retail chains in India Reliance Retail

Major Indian retailer Reliance Retail has implemented support for digital rupee payments in one of its Freshpik stores and plans to expand this experience to all formats of the network.

One of the largest retail chains in India, Reliance Retail, began accepting digital rupees as part of a pilot project.

V Subramaniam, chief executive of Reliance Retail, noted that the adoption of a central bank digital currency (CBDC) is in line with the firm’s vision of providing “choice” to Indian consumers. The executive also emphasized that this initiative gives the firm the opportunity to offer an alternative payment method in its stores.

To make a purchase, customers only need to scan a QR code.

“Indians will get another efficient and secure alternative payment method” — said the top manager.

The deployment of CBDC was made possible through collaboration with ICICI Bank, Kotak Mahindra Bank and Innovative Technologies.

Plans for the country’s CBDC were laid out by the Reserve Bank of India (RBI) on October 7, 2022. The country’s central bank has identified various factors, including the potential positive and negative impact of the digital rupee on the country. According to the RBI, one of the motivations for creating a CBDC is to reduce the operating costs of managing cash.

Overtaken by TikTok ChatGPT has become the fastest growing online

The ChatGPT neural network turned out to be the fastest growing online service in the world. It took only 2 months to reach an audience of 100 million people a month, Reuters reported. A similar figure for TikTok was reached in 9 months. The very same public version of ChatGPT was launched on November 30, 2022, and not even in all countries.

Note that other online services, social networks or platforms have reached such a figure in only a few years.

Also today, OpenAI introduced ChatGPT Plus, a paid version of the chatbot for $20 per month. However, it is only available in the US and by appointment only.

And Microsoft plans to add a new GPT-4 language model to its Bing search engine, which hasn’t even been announced yet. In addition, the ChatGPT mobile application and a neural network for generating video by text queries are expected.

It seems that Samsung took into account the problems with the Galaxy S22 line of smartphones and did not repeat them in new devices when it comes to cooling systems.

Well-known insider Ice Universe has published a visual comparison of the approximate sizes of cooling systems in each flagship of the past generation and the new one.

As you can see, all systems have become noticeably larger, and in the younger model, instead of a graphite film, an evaporation chamber has appeared.

Whether this is enough for the new products not to overheat and not throttling so much, tests will show, but the performance, as we can already see, is really good. Recall that today we also saw a comparison of the Galaxy S22 Ultra and S23 Ultra cameras.

Ice Universe was the first to accurately talk about the new trend for smartphones with waterfall screens, about the notch in the iPhone X, about the new design of the iPhone 14 and about Samsung’s 200-megapixel image sensor.
