More solar panels in Tokyo

16.09.2022

The Tokyo Metropolitan Region Government has announced a new policy that mandates the installation of solar panels on some of its new homes as part of a move to promote the use of solar energy. The initiative is scheduled to start in 2025 and will be the first of its kind in Japan, according to The Japan News.

About 50 developers building buildings with a total area of at least 20 m2 per year will fall under the new rules requiring the installation of solar panels.

However, the proportion of solar panels required for installation will differ from area to area, taking into account the degree of insolation in a particular place. For example, if in the districts of Chioda and Chuo, where many tall buildings are located, 30% of the roofs should be covered with panels, then in low-rise areas - up to 85%. Since the life cycle of panels is about 20-30 years, the county government will also set up a system to promote their recycling with an eye to preparing for the mass replacement of panels in the future. Panel leasing is not excluded, as well as subsidies for home buyers and other benefits.

According to the publication, some developers are expressing concern about additional costs that can raise the cost of housing. In response, with the start of the program, the authorities promise to strengthen support measures.

Starting in the spring of 2025, new homes across the country must meet certain energy efficiency standards - for example, developers must use materials with a high level of thermal insulation. The local authorities decided to launch their "solar" initiative at the same time as the start of the implementation of national standards in order to make it easier for builders.

Tokyo Metropolitan Governor Yuriko Koike said she hopes the new initiative will be a turning point in history, after which it can be said that "Tokyo has changed."

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 ... >>

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, ... >>

Gamma-ray telescope in the Canary Islands 08.06.2004

A new gamma-ray telescope, designed by scientists from Germany, Belgium, Italy, Switzerland and Spain, went into operation on the island of Palma (Canary Islands).

The telescope registers gamma-ray fluxes from space not directly, but by Cherenkov radiation, which gamma particles generate in the upper atmosphere. A 234-square-meter swivel mirror made of carbon fiber and aluminum captures the flashes that occur at altitudes of 10-20 kilometers, when gamma rays strike air atoms and create charged particles rushing towards the Earth.

The rays of light reflected by the mirror are concentrated on a camera of 577 highly sensitive sensors. The computer, analyzing the data from the camera, calculates the trajectory of the initial beam of gamma rays. This will allow physicists to understand the nature of radiation sources. The telescope can look into the depths of the universe for eight billion light years.
