China launches world’s first neodymium-powered ‘sky train’

Published

China launched the world’s first maglev overhead line built with neodymium magnets that can keep the sky train afloat forever – even without a power source.

An 800-meter-long experimental railway in southern China’s Xingguo County, Jiangxi Province, uses powerful magnets rich in rare earth elements to generate a constant repulsive force sufficient to lift a train carrying 88 passengers into the air. This was reported by the state broadcaster China Central Television.

Unlike most existing maglevs, the suspended train travels about 10 meters above the ground at a speed of 80 km/h. According to the creators from the Jiangxi University of Science and Technology, under free-floating and friction-free conditions, only a small amount of electricity is needed to move the train.

The new maglev technology generates little electromagnetic radiation, and the cost of building it is about a tenth of the cost of building a subway, they said. The local transport authorities said that after several test runs, the line will increase to 7.5 km and its maximum operating speed will reach 120 km/h.

Ordinary magnets with opposite poles can repel each other, but their magnetic strength weakens over time. Adding rare earth elements to a magnet greatly increases its lifespan. Neodymium, for example, can reduce the loss of magnetism to less than 5% per century. Therefore, rare earth magnets are called permanent magnets.

“The permanent magnet maglev train offers personalized and intelligent transportation that can complement metro and light rail,” says one of the creators. “In the future, it will also help create a new engine for the high-tech equipment industry and give China a new advantage in global rail transport.”

The US Department of Defense will be the first to receive products on the 18A process from Intel

Intel said that products based on the 18A process technology will primarily be produced for the needs of the US military.

The US Department of Defense will be the first to receive products on the 18A process from Intel

More specifically, the US Department of Defense will be the first Intel customer to receive the relevant semiconductor solutions. Intel already has a contract worth $250 million, and it does not concern the purchase, but for now only the design and development of next-generation chips. The contract for the purchase of such products will bring Intel much more money.

Process 18A is already being actively developed by Intel. The company claims that it will launch related products in 2024, but this, as we understand it, will not affect consumer solutions. When Core processors on such a technical process will appear on the market is still unknown.

The 18A process itself is difficult to correlate with others, which are described in a more familiar form with nanometers. The name of the process technology indicates 18 angstroms, that is, it is 1.8 nm. Given that the Intel 7 process is actually 10nm and the Intel 4 is actually 7nm, it’s likely that 18A can be loosely called 3nm. On the other hand, for quite some time now, the number of nanometers in the name of the process technology says little, and each company considers it differently.

Acer decided to enter the video card market and not with Nvidia or AMD products. Acer has unveiled its first 3D card today and it’s the Arc A770 Predator BiFrost.

Whether Acer will release only Intel cards is still unknown. In this case, we can see a non-reference design, two eight-pin power connectors at once (the reference card has 6 + 8 connectors) and a very unusual cooling system with two fans, which are very different both in size and design. The smaller one is completely similar to the centrifugal one, but it is impossible to say for sure from one image.

There is also no data on the Acer card yet. Recall, Arc A770 has 8 or 16 GB of memory and 4096 FP32 blocks. The card is priced at $330 or $350, depending on the version. Intel also introduced the more affordable Arc A750, priced at $290.

Camera module for half a smartphone Tecno Phantom X2 camera

In the FCC database, the Tecno Phantom X2 smartphone was lit up, which, first of all, will impress with the dimensions of the main camera module.

As you can see in the drawing, the module will be huge. In terms of the size ratio of the module to the size of the smartphone itself, it is even larger than that of the Xiaomi 12s Ultra.

Of course, the dimensions of the module do not at all mean that the new Tecno will also have a large inch image sensor. Given what the company produces, this is unlikely.

As for other parameters, the FCC base says a 5040 mAh battery with 45-watt charging and Bluetooth 5.3.
