Comments on the article
The growing interest in energy resources is associated with global warming and the consequences of the greenhouse effect. Today, people understand that fossil fuels are limited and their use leads to environmental pollution: for example, the emission of carbon dioxide leads to global warming, and sulfur dioxide is the cause of acid rain. If we take this into account, then the use of renewable energy sources (RES) becomes more and more attractive, which include: solar radiation, wind energy, the energy of rivers, tides and ocean waves, the energy contained in biomass and organic waste.
Wind energy has been known to mankind for at least 2000 years; in the last 10 - 15 years, its use for the production of electrical energy has been rapidly developing. To date, more than 20.000 wind turbines have been installed worldwide, with a total capacity of over 16 million kW. Modern wind power plants (wind turbines) have a capacity from a few kilowatts to several megawatts and make it possible to convert wind energy cost-effectively with a high degree of reliability.
Wind turbines can be used for various purposes, ranging from charging batteries (AB) and powering various objects (houses, farms, etc.) to supplying electricity to a centralized power supply network.

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 ... >>
| Random news from the Archive knee joint power generator
16.07.2008
In Canada, the production of an electricity generator has begun, which is put on the knee joint, almost does not interfere with walking and generates about five watts of power. In this case, the generator is turned on only in the deceleration phase, when the leg moves by inertia, so that the carrier of the generator almost does not have to exert extra effort.
From the "knee pad" you can charge portable electronic devices. One hundred steps at a moderately fast pace provides ten minutes of conversation on a cell phone.
The developers intend to increase the power and reduce the weight of the device.
