Transformer for China

09.07.2009

By order of the People's Republic of China, the German electrical engineering firm Siemens designed and built an 800 kilovolt transformer.

A transformer the size of a two-story cottage is now awaiting delivery to China. A 1400 km long transmission line from Yunnan to Guangdong will require ten such giants and the same number to transfer energy from a new hydroelectric power station in the southwest of the country to Shanghai (the line is more than 2000 km long).

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, ... >>

Music server on ARM processor 22.05.2013

Design and manufacturing company BitBox from Basingstoke (England) has created a music server on the ARM processor. The music server has three separate audio outputs controlled via a wireless keyboard or web browser. The design from BitBox is based on the ARM Cortex-A8 Freescale i.MX512 processor. It runs Debian Linux, and the hardware includes a SATA interface for the hard drive, Ethernet ports, USB, and a serial interface.

"We used open source compilers to generate the code, and we wrote our own libraries to avoid using heavy Glib libraries," BitBox said.

To provide maximum control over the hardware, the company also wrote its own loaders for processors. BitBox manufactures a significant number of these music servers as off-the-shelf products that are already available to customers.

The company specialized in ARM-based devices and has recruited a design team in Basingstoke with a wide range of design skills, including analog electronics, high-speed digital, FPGA design, CAD input, and PCB design in Cadence Orcad and Allegro. Their experience with processors covers ARM9, ARM Cortex-M3, M4, A8 and STM8, and programming for them in C, C++ and assembler. BitBox also creates multiple application base designs and IP elements.

The design department has significant design for manufacturing (DFM) experience and can offer mass production and lifecycle management for the products they create. The production base allows for: surface mounting with a pitch of 0,8 mm, wave soldering, manufacturing of cases, testing - in-circuit, optical, functional and limiting modes and component control.

"Conditions about outsourcing in electronics design and manufacturing are changing," the company said. "Some offshore design and manufacturing advocates have found that perceived cost savings have been offset by the need for remote project management, especially for products and components in small to medium batch production." .

At its manufacturing facility in Basingstoke, the company conducts design, prototype testing and series production.

"There's an advantage to being able to 'touch' the design and optimize the design as it's built, and have control over the mass production and delivery process that's always at hand," the company says.

The company's projects are used in medical, audio, power management and industrial applications, including RFID, ZigBee, MEMS, Bluetooth, GPS and Galileo technologies.
