Chapter 662: Many Problems 《Seeking Monthly Pass》
Project of Professor Ji Qianwu. Everyone is very interested, but after hearing the omen... Zhuang, Hou. I was immediately speechless, and no one expressed interest in this project.
Professor Wu looked around and felt deeply disappointed when he saw that although some people were interested, no one dared to respond.
Against the background of the peak of petrochemical energy and the constraints of emission reduction and other issues, people are vigorously pursuing new energy, and the hottest field is undoubtedly solar energy.
The energy generated by the sun shining on the earth for one hour is enough to meet the current energy needs of the world for an entire year. Because of this, the use of solar energy is seen as the ultimate way to break away from dependence on oil.
If we can utilize solar energy in a resource-saving manner and obtain net energy profits, mankind will truly be said to have inexhaustible energy.
At present, solar energy utilization technology has made rapid progress around the world, but the proportion of solar energy used is far less than one percent of the world's total energy consumption. High cost is an important reason why solar energy is not widely used.
Most solar cells used today are made of silicon because silicon is more efficient than other materials. However, silicon is a more difficult material to work with. In addition, its manufacturing process also requires a large amount of water and energy. The latest material to replace silicon is photovoltaic thin film, but photovoltaic thin film is not as efficient as silicon, and the same power generation requires more photovoltaic thin films.
However, when it comes to whether solar cells can generate a net energy profit, that is, produce more energy than they consume, there is no clear answer now or in the future.
For now, making solar cells directly consumes slightly less energy than they produce. So it looks like it can generate a net energy profit.
But to solve the problem of solar energy utilization, the biggest problem is energy storage. Because sunlight only shines during the day, and there may not be sunlight during the day. If we are to rely entirely on solar energy, we must find ways to store it. So far. Scientists have yet to find a cost-effective way to store solar energy. The two methods currently developed, compressed air and battery storage, are very expensive.
To date, the most successful thin-film photovoltaic technology is dilute radiation, which may bring the cost of solar power to parity with existing electricity costs.
But thin film technology relies on dilute, which is one of the rarest metals in the world and is used in memory chips and optical discs. And is used as a fortifier of copper and copper. As long as thin film technology is significantly improved, demand for thin films will inevitably rise. Some geologists believe that, even under current use, the resource will become scarce within twenty years.
Most of the metal comes from the refining of copper, but as energy prices rise, the cost of mining copper becomes more expensive, and the price of scrap is increasingly facing upward pressure.
In short, although there is definitely room for development of photovoltaic technology in the future, photovoltaic technology is still far from being widely used. At least thin film technology and solar energy storage technology still need to improve.
Although Professor Wu was very disappointed, Fan Wubing had put some thought into this, but he didn't know where the current frontier for Tai Neng's use was, so he couldn't say anything rashly. After all, he was a network expert. I had a fight with a deputy governor. If I show my face again now, it will inevitably attract more criticism from people.
However, just because he stopped talking does not mean that others have no thoughts on what he just said. Boss Zhu called his secretary and asked him to do something and check the details of Top Company in detail. What Fan Wubing said. Just how much hits home.
The secretary's work efficiency is quite high. In other words, it took half an hour to put a relatively detailed digital information in front of Boss Zhu.
After he turned a few pages, his face became very ugly. It was obvious that this information had confirmed Fan Wubing's accusation. Top Company is not a serious software company at all, but a leather company that makes money in the stock market under the banner of high technology.
After Boss Zhu finished reading, he pushed the information to the side and motioned to Fan Heng.
Fan Heng felt a little unnatural because of his son's Internet talent. After all, many people at the scene knew about the father-son relationship between the two. Seeing Fan Wubing so blatantly making a deputy minister unable to come to the stage, he also murmured in his heart. , I don’t know where to start from.
Seeing that Fan Wubing had stabilized at this time, Boss Zhu asked him to read a piece of information. He was a little unsure, but he always felt that Fan Wubing basically didn't talk nonsense. Since he was criticizing a family like this company, then this company must not be a seamless egg!
Sure enough, Fan Heng glanced at it and discovered that it was an investigation document against Top Company. Comparing some of the above numbers, needless to say, it can be proved that Fan Wubing's fierce speech was definitely not just talking nonsense.
"After Fan Heng read the information, he returned it to Boss Zhu, but he didn't know how to speak.
"Wu Bing is right, for the sake of political performance, the courage of local governments" Cai Se P Chapter Table of Contents Chapter 662 Many Problems "Asking for Monthly Votes"
"How big a company is this?" Boss Zhu said to Fan Heng with an unkind expression. It was actually able to receive strong support from the province. In addition to seeing the corruption problem, there was also the desire of local officials for political achievements. It is easy to understand why one does something that violates basic principles in order to gain motivation for promotion.
In fact, he has now thought it through. There are not a few such things in the current stock market. Therefore, there is a year of good performance, two years of losses, and three years of staring. The delisting of four stocks is happening all the time. The congenital defects of the Chinese stock market have led to this strange phenomenon. If the stock market operation system does not change, this kind of thing is inevitable.
"Although Wubing is right, we can't catch him now." Fan Ting thought for a while and said, "After all, if a company wants to expand, it needs financing, and after financing, it will expand. You have to leave enough time for others to develop, so that you can see whether it is a shell company or a real software company."
Boss Zhu nodded, and was a little helpless. If you want to find the root cause of the problem, you should first find out who put this company into the stock market. A company in this situation does not have the qualifications to go public at all, but it went public and hyped it up very much. This is a problem.
Without the joint efforts of the government and enterprises, this kind of thing would never happen, but if you want to investigate it carefully, it will inevitably be a long-lasting process, and every process of obtaining evidence will be very difficult.
"Son of a bitch!" Boss Zhu couldn't help but curse again, obviously very angry.
Professor Wu's eyes were already exquisite, and another economist went up to talk about the current real estate development issues. The debate was very heated. After all, this was the most closely related to the lives of ordinary people.
Seeing that everyone's attention was there, Fan Wubing quietly approached Professor Wu, and then made a gesture of invitation. The two walked to the corner next to him and found a table to sit down.
"Is Mr. Fan interested in my project?" Professor Wu saw that Fan Wubing was looking for him, of course there could be no other reason, so he asked happily. He knew that Fan's Investment Group was rich. If he could sponsor his scientific research or realize a batch of commercial solar energy utilization equipment, it would be quite constructive.
"Do you have any more mature projects now?" Fan Wubing asked directly.
"Road lighting and solar heating are both feasible, but the key problem is the lack of materials. Professor Wu said very frankly.
In general, solar lighting is still very promising. A set of 400-watt conventional street lights consumes more than 1,000 kWh of electricity a year, which is equivalent to consuming more than 400 kilograms of standard medium. If a thousand sets of 150-watt solar street lights with equivalent lighting effects are replaced, more than one million kWh of electricity can be indirectly saved a year, saving more than 400 tons of standard medium.
If a city or a thousand cities are replaced with such solar street lights, the energy saved will be a very astonishing amount. By extension, if this scope is further expanded and gradually enters the homes of residents, the energy that can be saved will be astonishing to everyone.
Professor Wu also mentioned that for a set of 150-watt solar street lights, the initial investment is as high as 15,000 yuan, while the cost of each set of conventional street lights is only about 8,000 yuan.
Although solar street lights have a long service life and can be equal to the investment of conventional street lights after many years, the cost of later maintenance and replacement is high. For example, solar street lights usually The lead-acid battery used. Its service life is only four to six years. During the service life of the solar street light, the expensive battery must be replaced three times.
The photoelectric conversion efficiency of the solar street light panel is low, which seriously affects the power generation efficiency of the solar street light. The cost of using solar energy to generate electricity is currently about three yuan per kilowatt-hour, which is much higher than conventional power generation. At the same time, for urban roads with high requirements for street light illumination, solar street lights still have defects such as narrow light coverage and uneven brightness, which become a big obstacle to the promotion and application of solar energy.
After listening to it, Fan Wubing pondered for a while and immediately found the problem. As a local government, even if it can invest a huge amount of money at one time to use solar street lights for road lighting projects, it will not be able to take out more funds for later maintenance and replacement, and the solar street lights will become a decoration.
Due to these constraints, solar street lights can only be promoted and applied in places such as urban community roads, parks, and towns where the brightness and illumination requirements are not high, and cannot enter the main battlefield of lighting on a large scale.
"This is really a difficult problem to solve." Fan Wubing shook his head.
