Toshiba superconducting electric motor

04.07.2022

Toshiba ESS Corporation has applied all of its expertise in nuclear and thermal technology to develop a prototype of a lightweight and powerful superconducting motor for "mobile applications".

The new electric motor weighs ten times less than fossil fuel engines of comparable power. This combination of characteristics will be appreciated in aviation and in the new field of air taxi with vertical takeoff and landing.

Toshiba's prototype superconducting electric motor measures 50 x 70 cm (excluding the shaft) and has a power of 2 MW. The company intends to start commercial production of such engines at the end of this decade.

The superconducting motor was developed by a team of engineers and experts at Toshiba ESS's Keihin Operations division, which is experienced in designing and manufacturing generators and superconducting products for the nuclear and thermal industries.

An electric propulsion system using the effect of superconductivity (probably, we are talking about high-temperature superconductivity) will save battery power in flight due to higher efficiency and lower current resistance losses.

According to experts, superconducting electric motors in aviation can save up to 30% of fuel compared to traditional technical solutions.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

TRACO TPI small economical power supplies 13.05.2021

TRACO Electronic AG has introduced a new line of compact, low cost, open-top designs for industrial applications, the TPI family. It includes the TPI 30JP, TPI 65JP, TPI 100J, TPI 125J and TPI 150J series in the power range from 30 to 150 W with the possibility of peak overload up to 120...140% for up to 10 seconds (depending on the series).

A feature of the family is a wide operating temperature range of -40...+85°C (with the dependence of the output power on the upper threshold). At full power, the sources operate in the range from -40 to +60 (50) ° С. At the same time, IP have a compact size and high efficiency. In models with a power of 100 W or more, a PFC circuit is implemented (PFC> 0,95).

The products are designed in accordance with the European Energy Directive and consume less than 300 mW at idle. They are designed for industrial automation systems, test and measuring instruments, as well as wherever reliable small-sized power supplies with a wide temperature range are required.
