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, ... >>

Key quantum security technology on a single chip 30.10.2021

Toshiba Europe announced the world's first Quantum Key Distribution (QKD) system-on-a-chip. This achievement will make it possible to apply quantum security technologies that are protected from future generations of supercomputers in the widest range of scenarios, including solutions for the "last miles" and the Internet of Things (IoT).

Miniaturizing the optical circuits used for QKDs and quantum random number generators (QRNGs) and integrating them into tiny semiconductor chips not only makes them much smaller and lighter than fiber optic counterparts, but also reduces power consumption.

It is especially important that such quantum devices can be manufactured in large quantities in parallel, on a single semiconductor wafer, using standard semiconductor industry technologies. For example, quantum transmitter chips developed by Toshiba have dimensions of only 2 × 6 mm, so several hundred such devices can be obtained from one plate at once.

The global QKD market is projected to grow to around $20 billion in fiscal year 2035. Major quantum-protected fiber networks are currently under construction in Europe and Southeast Asia, and there are plans to launch satellites that could expand these networks to a global level.

In October 2020, Toshiba launched two fiber QKD products built around discrete optical components. Together with project partners, Toshiba has deployed quantum-secure metro networks and long-distance fiber backbones in the UK, Europe, the US and Japan.
