Chapter 662 Problems
Everyone was very interested in Professor Wu’s project, but after hearing the project... Zhuang, I was speechless and no one expressed interest in this project.
Professor Wu looked around and saw that although someone was interested, no one dared to respond, and couldn't help but feel deeply disappointed.
Under the constraints of the peak of petrochemical energy and emission reduction issues, people are pursuing new energy, and the hottest field is solar energy.
The energy generated by the sun shines on the earth for an hour is enough for the world's current energy demand throughout the year. Because of this, the use of solar energy is seen as the ultimate way to get rid of oil dependence.
If we can use solar energy in a way that saves resources and obtains net energy profits, humans will truly have inexhaustible energy.
At present, solar energy utilization technology has made rapid progress worldwide, but the proportion of solar energy use is far less than one percent of the global total energy consumption. High costs are an important reason for the lack of widespread use of solar energy.
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 deal with. In addition, its manufacturing process also requires a lot of water and energy. The latest material to replace silicon is an optoelectronic film, but the optoelectronic film is not as efficient as silicon, and the same power generation requires more optoelectronic films.
However, when it comes to whether solar cells can generate net energy profits, that is, when energy output is greater than energy consumption, there is no clear answer now, whether it is present or future.
For now, manufacturing solar cells consumes slightly less energy directly than they produce. So it seems that it can generate net energy profits.
However, to solve the problem of solar energy utilization, the biggest problem is energy storage. Since sunlight only shines during the day, and there is not necessarily sunlight during the day. If you want to rely entirely on solar energy, you must find a way to store solar energy. So far, scientists have not found an economical and 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 photoelectric thin film technology is thinning radiation, which probably keeps the cost of solar power generation equal to existing electricity costs.
However, thin film technology needs to rely on thin, and thin is one of the rarest metals in the world, used in memory chips, optical discs, and is used as a reinforcer for wrong and copper. As long as thin film technology is significantly improved, thin demand will surely rise steadily. Some geologists believe that even under existing use cases, thinness will become very scarce within 20 years.
Most of the thinness comes from copper refining, but energy prices have risen, copper mining costs have become more expensive, and fragmented prices are facing increasing pressure.
In short, although there will definitely be room for development in the future, optoelectronic technology is far from being widely used, and at least thin film technology and solar energy storage technology still need to be improved.
Although Professor Wu was very disappointed, Fan Wubing put some thoughts on this, but he didn't know where the frontier position that was too utilitarian was, so he couldn't say anything rashly. After all, he had just fought with a deputy governor on the Internet. If he showed up again, it would inevitably attract more criticism from others.
However, he stopped talking, which did not mean that others had no idea about what he said just now. Boss Zhu called his secret and asked him to do something, and checked the details of Top Company in detail to see what Fan Wubing said. How many of them hit the nail on the head.
The secret's efficiency is quite high. It only took half an hour to put a detailed digital data in front of Boss Zhu. After turning a few pages, his face looked very bad. Obviously, this data has confirmed Fan Wubing.com's accusation. Top Company is not a serious software company at all, but a bag company that makes money in the stock market under the banner of high-tech.
After reading it, Boss Zhu pushed the information to the side and signaled Fan Hengye.
Fan Heng was a little unnatural because of his son's website. After all, many people on the scene knew about the father-son relationship between the two. Seeing Fan Wubing so openly preventing a deputy ministerial-level from coming to Taiwan, he also muttered in his heart, not knowing where this should start.
At this time, seeing Fan Wubing calm down, Boss Zhu asked him to read a piece of information, and he felt a little unsure. However, he always felt that Fan Wubingji was not talking nonsense. Since he criticized a company like this, the company must be a sewn egg!
Sure enough, Fan Heng glanced and found that this was a survey data against Top Company. After comparing some of the numbers, it was necessary to prove that Fan Wubing.com's fierce speech was definitely not a silence.
"After reading the information about this, Fan Heng gave it to Boss Zhu, but he didn't know how to speak.
"It's still right that Wuya said it's right. For political achievements, the local government's courage. "The Directory of Finance and Sex Chapter 662 has many problems. "Please vote for monthly votes"
A few big 0's" Boss Zhu said to Fan Heng with a bad expression, "With this panicked company, you can actually get strong support from the province. In addition to seeing the problems, there is also the desire for political achievements of local officials. In order to gain the motivation to advance, doing something that violates the basic principles is easy to understand.
In fact, he has now thought it through. There are not a few such things in the current stock market, so he has excellent performance in one year, losses in two years, and attention in three years. The four delisting incidents are happening all the time. The innate 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 will be inevitable.
"Although Wubing is right, he can't catch others' handle now." Fan Ting said after thinking for a while, "After all, if a company wants to expand, it needs financing, and after financing, it is expansion. You have to leave enough development time for others to see if this is a bag company or a real software company."
Boss Zhu nodded, and was a little helpless. If we want to investigate the root of the problem, we should first investigate who put the company into the stock market. In this case, the company does not have the qualifications to be a market, but he is in the market and is hyped very much. This is a problem.
Without the joint cooperation between government and enterprises, this kind of thing would never happen, but if you have to carefully investigate it, it will inevitably be protracted and every process of obtaining evidence will be very difficult.
"Boss!" Boss Zhu couldn't help but curse again, obviously he was extremely angry.
Professor Wu's eyes were already very particular. He changed to an economist to talk about the current real estate development issue. Everyone was very arguing. After all, this is the most closely related to the lives of ordinary people.
Seeing that everyone's attention was there, Fan Wubing quietly approached Professor Wu, then made an invitation, and the two walked to the corner next to him, found a table to sit down.
"Are Mr. Fan interested in my project?" Professor Wu saw that Fan Wubing was looking for him, of course there was no other reason, so he asked happily, knowing that Fan's Investment Group is rich. If he can sponsor himself to do 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 Wubing asked directly.
"Road lighting and solar heating are all feasible, but the key issue is the lack of materials. Professor Wu said very frankly.
From a broad perspective, solar lighting is still very promising. A set of 400 watts of conventional street lights consumes more than 1,000 kW of electricity per year, which is equivalent to consuming more than 400 kilograms of standard media. If you replace a set of 150 watts of solar street lights with a comparable lighting effect, you can indirectly save millions of kW of electricity per year and save more than 400 tons of standard butterflies.
If a city or a thousand cities are replaced with this kind of solar street light, the energy saved will be a very amazing amount. By extension, if this range is increased, it will gradually enter residents' homes. Then, the energy saved will be shocked.
Professor Wu also mentioned that for a set of 150-watt solar street lamps, the initial investment is as high as 15,000 yuan, while the cost of each set of conventional street lamps is only about 8,000 yuan.
Although solar street lights have a long service life and can remain the same as conventional street light investments after many years, the cost of later maintenance and replacement is higher, such as the lead-acid battery commonly used in solar street lights. Its service life is only four to six years. The expensive battery must be replaced three times during the service period of solar street lights.
The photoelectric conversion efficiency of solar street lamp panels is low, which seriously affects the power generation efficiency of solar street lamps. The cost of using solar energy 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 street lamp illumination requirements, solar street lamps also have defects such as narrow light coverage and insufficient brightness, which has become a major obstacle to the promotion and application of solar energy.
After hearing this, Fan Wubing thought about it and immediately discovered the problem. As a local government, even if he could invest huge amounts of money at one time and use solar street lights for road lighting projects, he could not provide more funds for later maintenance and replacement, and solar street lights became decorations.
Due to these constraints, solar street lights can only be promoted and applied in urban communities, roads, parks, townships and other places with low brightness and illumination requirements, and cannot enter the main lighting battlefield on a large scale.
"This is really something that is difficult to solve." Fan Wubing shook his head and said.
