The best location for a wind turbine is on top of a hill or in the middle of a field. But in real life, things are much more complicated. If you want to install a wind turbine near the house, then the height of the mast should be 3-5 m higher than the house, or if the mast is lower, it must be installed from the house at a distance of at least 3 times the height of the house, that is, if the height of the house is 10 m, then the mast should be placed no closer than 30 m from the house. In the presence of tall trees, the distance to them should be at least 2 times the height of the tree. All this imposes additional costs on the owner of the "windmill" in electrical wiring to the consumer directly, its length will increase, as well as energy losses.
Below in table. 2.2 provides information about different wires with a large cross section (recommended for installation as part of a wind turbine) and the resistance of conductors per 100 m of length. Domestic cable PVS-3 / 2,5 (bay 100 m) costs 4 thousand rubles.
Table 2.2. Characteristics of wires for connecting powerful energy consumers in DC circuits
A high mast, among other things being equal, is more beneficial, since the wind at a height of 15-20 m will give an increase in electricity generation by more than 20% compared to a mast half as low, especially in built-up areas or saturated with tall trees.
It is not recommended to install wind turbines in ravines and depressions (by definition), as well as on the roof of the house, since noise and vibration in this case will be noticeable.
Thus, the height of the mast on which the wind generator is installed is important. It allows you to avoid the so-called "dead corner", in which even a medium-strength wind for a "windmill" is not effective.

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 MiniSKiiP with thermal paste application
25.05.2007
SEMIKRON offers its customers a new service: the supply of MiniSKiiP miniature IGBT modules with a pre-applied layer of thermally conductive paste. This option allows you to simplify the installation process by eliminating an important and critical technological step, improve the thermal performance of the structure and ensure a high repeatability of the production process.
To ensure high stability of thermal parameters, SEMIKRON uses heat-conducting pastes from leading European manufacturers: Wacker P12 (silicone-based) and Electrolube HTC.
The new option provides the following advantages: quick and easy installation of modules on the heat sink, the ability to automate production; optimal thickness of the paste layer, reducing the risk of damage to the MiniSKiiP ceramic base; optimal paste distribution in the gap, uniform heat dissipation, minimum thermal resistance; good temporal stability of thermal characteristics.
