Wind power will fully provide Brazil with electricity

06.11.2013

Brazil's economy is growing rapidly and the country's electricity demand is expected to increase by 50% over the next decade. Currently, a significant part of the energy is generated by hydroelectric power plants, but the government does not want to seriously increase the number of dams in the country, and therefore draws attention to another abundant source of energy - wind. So far, there are not many powerful wind farms in the country, but explosive development of this direction is expected in the near future.

Strong and constant winds are observed in large expanses of Brazil - these are excellent conditions for installing windmills. The same wind turbines will be more efficient here than in many other parts of the world. The current goal is to meet 2021% of the country's electricity needs from wind power by 10.

This energy is enough to provide electricity to Sao Paulo, the largest city in South America, which is home to about 11 million inhabitants. Renova Energia, a wind turbine company, says wind power is a good addition to hydroelectric power, because when it rains, the winds weaken, and when there are strong winds, it usually does not rain.

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, ... >>

Seagate 4TB Portable Drive 12.07.2014

The new representative of the line of external drives is officially presented - Seagate Backup Plus Fast, the first device of this class with a capacity of 4 TB. Unlike desktop DAS (Direct Attached Storage) of this capacity, which use 3,5-inch hard drives, the Seagate product consists of two 2,5-inch 2TB HDDs.

The device is available in an aluminum case in a single color - black. The USB 3.0 interface is used to connect to a PC. A distinctive feature of Backup Plus Fast: in addition to the USB cable, no additional power sources are required.

The package includes both a regular cable and with two connectors - in case a single port cannot provide sufficient current.

Hard drives inside the drive are combined into an array with a single address space, the partition is formatted in NTFS. To support write operations in OS X, you can install the NTFS driver directly from the drive itself.
