Vol 5 Chapter 662: Many problems "seeking a monthly pass"

Ji Gan Professor Wu's project. Everyone is very interested, but I heard the omen...Zhuang and Hou. Suddenly I was speechless, and no one expressed interest in this project.

Professor Wu looked around, and saw that although some people were interested, no one dared to respond. He couldn't help but feel deeply disappointed.

Under the background of the peak of petrochemical energy and the constraints of emission reduction issues, people are pursuing new energy vigorously, and the hottest area is solar energy.

The energy produced by the sun illuminating the earth for one hour is enough for the current world's energy demand throughout the year. Because of this, the use of solar energy is seen as the ultimate way to get rid of dependence on oil.

If solar energy can be used in a resource-saving way to obtain net energy profits, mankind can truly be said to have inexhaustible and inexhaustible energy.

At present, the utilization technology of solar energy has made rapid development around the world, but the proportion of solar energy usage is far less than 1% of the total energy consumption in the world. The high cost is an important reason why solar energy has not been widely used.

Most of the solar cells used today are made of silicon, because silicon is more efficient than other materials. However, silicon is a more difficult material to handle. In addition, its manufacturing process also requires a lot of water and energy. The latest material to replace silicon is photovoltaic thin films, but photovoltaic thin films are not as efficient as silicon, and more photovoltaic thin films are needed for the same amount of power generation.

However, when it comes to whether solar cells can generate net energy profits, that is, when the output energy is greater than the consumption energy, there is no clear answer now or in the future.

For now, the energy directly consumed by manufacturing solar cells is slightly lower than the energy they produce. So it seems that it can generate net energy profits.

But to solve the solar energy utilization, the biggest problem is energy storage. Because the sunlight only shines during the day, and there may not necessarily be sunlight during the day. If you want to rely entirely on solar energy, you must find a way to store it. So far. Scientists have not found an economical way to store solar energy. The two methods currently developed, compressed air and battery storage are very expensive.

So far, the most successful photovoltaic thin film technology is thinning radiation, this technology probably makes the cost of solar power generation equal to the cost of existing electricity.

But thin film technology needs to rely on rare, and rare is one of the world's rarest metals, used in memory chips, optical discs. And it is used as a strengthening agent for wrong and copper. As long as thin film technology is significantly improved, the demand for rare earth will surely rise. Some geologists believe that even under current usage conditions, scarcity will become very scarce within two decades.

Most of the rare earth comes from the refining of copper, but the price of energy rises, the cost of copper mining has become more expensive, and the crushing price is also facing increasing pressure.

In short, although there is definitely room for development of optoelectronic technology in the future, optoelectronic technology is far from reaching the point of widespread use. At least thin film technology and solar energy storage technology still need to be improved.

Although Professor Wu was very disappointed, Fan Wubing took some thoughts on it, but he didn’t know where the frontiers were too much to be used, so he couldn’t say anything rashly. After all, his own net talent I had a fight with a deputy governor, and if he showed up again at this time, it would inevitably attract more people's criticism.

But he stopped talking, it doesn't mean that others have no idea about what he said just now. Boss Zhu called his secretary and asked him to do something, to check the details of Top Company. Those words that Fan Wubing said. How many are hitting the point.

The efficiency of the secretary is quite high. In other words, it took half an hour to put a more detailed digital data in front of Boss Zhu. After turning a few pages, his face looked very ugly. Obviously this data has confirmed Fan Wubing. The accusation of the net talent. Top Company is not a serious software company at all, but a leather bag company that uses the high-tech banner to make money on the stock market.

After Boss Zhu finished reading it, he pushed the information aside and signaled to Fan Heng.

Fan Heng was a bit unnatural because of his son's internet. After all, many people at the scene knew the father-son relationship between the two. Seeing Fan Wubing so blatantly preventing a deputy minister from coming to Taiwan, he was a little bit unconscious in his heart. , I don’t know where to start.

At this time, seeing that Fan Wuyao was stabilized, Boss Zhu asked him to read a document, and he was a little uncertain in his heart, but he always felt that Fan Wuyao basically didn't talk nonsense, since he criticized the family in this way. Company, then this company must not be an egg without seams!

Sure enough, Fan Heng glanced twice and found that this was a survey of Top Company. Comparing some of the figures above, it goes without saying that it can prove that Fan Wubing’s fiercely worded speech is definitely not a rhetoric.

"After reading the information, Fan Heng returned it to Boss Zhu, but he didn't know how to say it.

"It's still right to say that it is not diseased. For the sake of political achievements, the courage of local governments"

It's very big," Boss Zhu said to Fan Heng with a grim look, "This is a panic company. In addition to seeing the corruption problem, there is also the desire of local officials for political achievements. In order to get the motivation to move upward, it is easy to understand something that violates the basic principles.

In fact, he also thinks about it clearly now. In the current stock market, this kind of thing is not rare. Therefore, he has a good performance for one year, a loss for two years, and an eye for three years. The four delisting events are happening all the time. The birth defects of the Chinese stock market have caused this strange phenomenon. If the stock market operation system does not change, this kind of thing cannot be avoided.

"Although it is correct to say that it is not sick, I can't grasp it now." Fan Ting thought for a while and said, "After all, the enterprise needs to expand. It needs financing. After financing, it is expansion. You have to leave it to others. With enough development time, we can see if this is a leather bag company or a real software company."

Boss Zhu nodded, but also a little helpless. If you want to investigate the root cause of the problem, you should first investigate who put the company on the stock market. In this case, the company is not eligible for listing at all, but it is listed, and it is hyped. Very powerful, this is a problem.

Without the concerted efforts of government and enterprises, this kind of thing is absolutely impossible, but it is bound to be time-consuming to investigate carefully, and every process of obtaining evidence will be very difficult.

"Buckling!" Boss Zhu couldn't help but cursed again, apparently in anger in his heart.

Professor Wu's eyes are already exquisite. He changed an economist and went up to talk about the current real estate development. Everyone was arguing very fiercely. After all, this is the thing that is 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 request. The two of them walked to the corner next to him and sat down at a table.

"Mr. Fan is 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 that he knew that the Fan Investment Group was rich. If you can sponsor your own scientific research, or realize a batch of commercial solar energy utilization equipment, it will be quite constructive.

"Do you have any more mature projects now?" Fan Wuyao asked directly.

"Road lighting and solar heating are more feasible, but the key problem is the lack of materials. Professor Wu said frankly.

From a big point of view, solar lighting is still very promising. A set of 400 watts of conventional street lights consumes more than 1,000 kWh a year, which is equivalent to consuming more than 400 kilograms of standard media and replacing it with 1,000 sets of lighting effects. The equivalent of a 150-watt solar street lamp can indirectly save millions of kilowatt-hours a year, saving more than 400 tons of standard butterflies.

If a city or a thousand cities are replaced with this kind of solar street lights, the energy saved is quite an amazing amount. By extension, if this range is enlarged, it will gradually enter the residents' homes~ www.wuxiaspot.com~The energy that can be saved, I am afraid that everyone will be stupefied.

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 later maintenance and replacement costs are relatively high, such as the lead-acid batteries usually used in solar street lights. Its service life is only four to six years. The expensive batteries must be replaced three times during the service life of the solar street light.

The photoelectric conversion efficiency of solar street light panels is low, which seriously affects the power generation efficiency of solar street lights. The cost of using solar energy to generate electricity is currently about three yuan per kWh, which is much higher than conventional power generation. At the same time, for urban roads with high requirements for street lamp illumination, solar street lamps still have defects such as narrow light coverage and insufficient brightness, which has become a big obstacle to the promotion and application of solar energy.

After hearing this, Fan Wubing pondered for a while, and immediately discovered the problem. As a local government, even if it can invest a huge sum of money in one-time to use solar street lights for road lighting projects, but then it can’t spend more money. In the later maintenance and replacement, the solar street light became a display.

Because of these constraints, solar street lights can only be promoted and applied in urban residential roads, parks, villages and towns where brightness and illuminance are not high at this stage, and cannot enter the main lighting battlefield on a large scale.

"This is really a difficult thing to solve." Fan Wubing shook his head.
