Use of water from natural reservoirs as a coolant. Basics of safe life

Fundamentals of Safe Life Activities (OBZhD)

The biggest problems thermal pollution associated with thermal power plants. Steam generation of electricity is inefficient, since it uses 37-39% of the energy contained in coal and 31% of nuclear energy. Despite all the shortcomings, thermal power plants continue to exist.

Much of the fuel's energy that cannot be converted into electricity is wasted as heat. The easiest way to get rid of this heat is to release it into the atmosphere. But a more economical way is to use water as a cooler with its ability to accumulate a huge amount of heat with a slight increase in its own temperature, so that it itself gradually releases heat into the air.

A serious environmental problem is the fact that the usual way to use water to absorb heat is to directly pump fresh lake or river water through a cooler and then return it to natural water bodies without prior cooling.

Power plants can increase the water temperature of reservoirs by 5-15 °C: if the initial temperature is 16 °C, then the water used at the station will have a temperature of 22 to 28 °C. In summer, it can reach 30-36 °C.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time.

During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up.

Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time.

Thus, it was shown that our perception of time is closely related to what we look at. Larger, less busy images create the illusion of time slowing down, while smaller, more detailed scenes can make it feel like time is speeding up. These findings open up new perspectives on how our brains process visual information and how we perceive the world around us.

Future studies are planned to confirm these results and refine the model of the visual system, as well as to study brain activity during perception.
