Tourist tips

solar radiation much stronger in the mountains than in the plains. At the same time, with increasing altitude, the proportion of ultraviolet radiation primarily increases.

The impact of ultraviolet rays on the human body is very high. Possible skin burns. The sun's rays adversely affect the retina, causing severe pain and sometimes temporary blindness.

To protect the eyes, it is necessary to use goggles with light-protective glasses. To protect the face, a wide-brimmed hat or gauze mask should be worn; halts and rest to organize in the shade. Water, and therefore snow and fog, perfectly reflect ultraviolet rays. Therefore, one should not forget that it is possible to get snow blindness and burns, even in the case when there is no direct sun exposure to the eyes.

Snow blindness is called snow blindness because it almost always occurs if you look not at the sun for a long time, but at pure snow, and not necessarily in the mountains, this is also not uncommon in the tundra. Even being in an illuminated cloud gives the same effect.

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 ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

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 ... >>

Skyscrapers - solar farms 18.01.2022

The US company Ubiquitous Energy has received funding for a project to develop green windows that can provide buildings with green energy. The organization received $70 million from investors.

Ubiquitous Energy wants to do its part to save the planet from global warming through innovative green energy mining methods. So, to power skyscrapers, the company plans to cover the windows of urban buildings with an additional layer that can process solar energy into electricity. The thickness of such a layer is only a few nanometers, and small wires connect the entire system to electrical appliances.

According to company director Susan Stone, the money received will go to the final preparation of the product to enter the market. "In the future, we will be able to make French windows (windows to the floor). We will turn skyscrapers into vertical solar farms," Stone said. By early 2024, the organization plans to launch large-scale production. In addition to office buildings, Ubiquitous Energy also focuses on residential buildings.

New glasses have a minus - the price. Coated windows will cost 30 percent more than normal windows. However, the manufacturer and investors rely on the urgent need to solve the problem of global warming, hoping that this factor will increase demand for the product. As solar panels, Ubiquitous Energy windows also perform worse than traditional competitors - they are 50 percent less efficient. This is due to their position in space: less sunlight falls on a vertical surface than on a horizontal one.

“But we made a useful surface that did not generate energy at all. Glass was always passive, and we made it active,” Stone commented on the problem.

China has also made a bet on solar energy in the fight against climate change. The country's government is actively financing the construction of new plants for the production of polysilicon, a material used to make photovoltaic cells for solar panels. Thus, it is planned to reduce the cost of producing batteries and increase the pace of implementation of projects in the field of renewable energy sources.
