Construction of the road from solar panels is being completed

26.12.2017

In the near future, work will be completed in China to create a fairly long section of the road covered with solar panels. The project is being implemented in Jinan, a city of sub-provincial significance, which is located in the northwestern part of Shandong province on the Yellow River. The length of the road with solar panels is about 2 km.

The coating consists of several layers. At the top is the so-called "transparent concrete": this material transmits light, and in terms of structural properties it is close to ordinary asphalt.

Under the "transparent concrete" are the actual panels with solar cells, which generate electricity. Finally, at the bottom is an insulating substrate.

At present, the installation of all elements has been completed, and specialists are carrying out work on connecting to the electrical network. It is assumed that in the future such highways will be able not only to provide electricity to road infrastructure facilities, but also to wirelessly recharge passing electric vehicles (provided that the necessary components of the energy transmission system are installed). The coating is strong enough to support the weight of trucks.

The world's first solar-powered highway opened in France about a year ago. The experimental section of the road has a length of 1 km, and the total area of solar panels is 2800 m2. An estimated 280 MWh of energy can be generated annually from solar panels. It can be used, say, to illuminate city streets at night.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Yamaha SR-C30A soundbar with compact wireless subwoofer 23.08.2022

Yamaha has announced the minimalist SR-C30A soundbar. The device is cheaper than the Sonos Ray analogue, which is considered the "measurement of quality" in the segment of low-budget soundbars.

The key differences between the promising device and the above standard are the presence of more options.

SR-C30A received:

HDMI ARC interface;
wireless subwoofer for displaying high bass;
Bluetooth streaming;
compatible with TV devices from 32";
virtual surround sound;
remote control option through proprietary software.

The number of speakers in the SR-C30A is half that of the Sonos Ray. Their size is 4,6 cm. The developers promise to endow the soundbar with "virtual surround sound". The device can be controlled remotely using special software.

Having a multi-point Bluetooth connection means you can switch between different inputs (Amazon Echo Dot, phones, etc.)

The announced presentation date for the SR-C30A is October, with an estimated cost of $279.

Sales will open immediately after the ceremony, representatives of the Japanese brand promise.
