Central receiver solar systems are capable of generating electricity at high capacities and are more efficient than other similar systems due to their high operating temperature. These types of power plants can be used to supply steam to thermal power plants and also to produce hydrogen. Because, like other solar systems, only energy from solar radiation is used, there are no problems with greenhouse gas emissions or environmental pollution. These systems are one of the few solar electrical systems that can properly store solar energy and inject the stored energy into the grid when necessary, such as at night or in cloudy weather. The above advantage can be used to store energy and deliver electricity during peak network times. A 100-megawatt power plant with a capacity of 12 hours of energy storage requires only 4,000 square meters of barren land and can well supply the energy needed by 50,000 households. There are millions of square meters of barren land in the central deserts and in the southern, southwestern and northwestern regions of Iran, which can be used as a source for solar energy production compared to hydropower.

Infection with the corona virus leads to short-term and long-term effects, which sometimes affect the sufferers for the rest of their lives. The effect of Corona on the human brain has been studied by many scientists. The new symptoms that have been observed in patients suffering from the disease of Covid-19 indicate the effect of the corona virus on the functioning of the human brain and nervous system. While examining and treating patients in New York, which is considered to be the most prominent state in America in terms of infection with the corona virus and the number of victims of the Covid-19 disease, apart from fever, cough, body pain and shortness of breath, new signs of the destructive effect of the corona virus on human health. They found that the brain and nervous system of the patients are also somehow involved in this disease. Among the characteristics of this new finding is confusion, forgetfulness and even convulsions caused by nervous pressure in patients with Covid-19, many cases of which have been observed in New York state; In such a way that some patients do not even know where they are and why they are in the hospital or what year we are in now. In most cases, these symptoms are related to the lack of oxygen in the blood; However, it has been observed that this memory disorder in some patients is not very proportional due to the level of pulmonary involvement with the virus. "Jennifer Frontera", a neurologist at Langone University Hospital in Brooklyn, one of the old parts of New York City, believes that according to the new findings, the issue of involvement of the brain and nervous system when contracting the new type of corona virus is now seriously discussed in it has been investigated.

Stroke, delirium, brain inflammation, encephalopathy or even confusion and neuromuscular disorders are part of the list of observed pathologies. The people who conducted this research emphasize that many people who experience these neurological symptoms are under 50 years of age and seemed to be in good health before the infection. American doctors believe that corona virus can lead to sudden stroke in young people, and according to scientific research, one third of corona patients suffer from neurological disorders within six months. Rapid reduction of brain gray matter has been observed in people with Covid-19. A new study has shown that even mild cases of Covid-19 can cause brain shrinkage and rapid gray matter loss. The study, published in the journal nature, examined brain scans of people before contracting the coronavirus and in the months after. This is the first case of its kind that has a longitudinal approach and examines changes over time. In this study, 785 people underwent two brain scans with a gap of about three years from each other. Among this group, 401 people were infected with the corona virus, most of which were mild cases that did not require hospitalization. The studied subjects were in the age range of 51 to 81 years. Of this group of people who got infected with the coronavirus, compared to people who never got infected, the level of gray matter loss in their brains was accelerated.

Regarding this question, it should be strongly said that in most cases the answer is yes. Many of these power plants' problems can be solved, and the national ORNL laboratories play an important role in this regard. Choosing the right place for the right design, design and management can lead to further solutions to these problems. As mentioned earlier, the use of fish ladders, aeration and flow control in large dams is one such solution. Environmental solutions have always existed, meaning that activities can be performed to eliminate or minimize the effects of these projects, or ultimately to compensate for them in some way. In hydropower projects, work can be done to resolve, alleviate, or mitigate the problem before it occurs. ORNL experts have been working for over a decade to effectively evaluate these problems and provide solutions to them. We are currently assisting the US Department of Energy to, with the help of industry, present a plan for the technological development of these power plants in an environmentally friendly manner. Large dams in the Pacific Northwest have stairways for fish that allow adult free fish to enter the river from the ocean to spawn young fish. The fish ladder is a classic example of this. Today, it is found that resident fish in one area also migrate seasonally to spawn to other areas and therefore need a crossing to cross.
