The earth energy is considered to be the “blue power” after green forces such as wind energy and solar energy. As a new force that can replace fossil power, the land energy has always been the focus of everyone. However, the problem of low conversion rate of waves has always troubled scientists.
Today, innovation in the form of electricity generation and advancement of power generation efficiency and modification of installation methods are the key technologies and bottle heads for wave power generation, and are the biggest challenges in the real “blue power” in the world. Recently, Wang Zhong, director and chief scientist of Nanotechnology and System Research Institute of the Chinese Academy of Sciences, led his team and first proposed a land energy collection method based on friction generator network structure, overturning the previous method of collecting land energy with electromagnetic inductance, and there is no hope of realizing industrialization within five years.
The potential of “blue power” is insignificant
The earth’s general situation is 70% covered by sea water, and 14 billion tons of sea water are stored in the land. The power of the sea is hiding from a large number of potential land power. This power of the sea is also called “blue power”.
With the severe drying and purification of soil mine fuel, some important soil countries in the world have turned their attention to soil.
Additional investment and accelerate the development of application of Manila escort programs have become a common understanding of humans. “A lot of energy hides in the land. Such a large power tank is worthy of deep exploration of humans. Blue power will have a great effect.” Wang Zhonglin said.
Be clear that green forces such as wind energy and solar energy are developing rapidly. However, in addition to the higher cost, the biggest limitation of wind and solar energy is the unstable and relatively large limitations of natural environments. This unchanged reality limits the development of green power.
In addition, the application of wind and solar energy is oftenDemand occupies a lot of air space. Although it can apply the wide Gobi, the Gobi status is generally more remote and dynamic transportation is more difficult.
The old estimate of the wave dynamics that can be converted around the global coastline can provide humans with 2.5 billion kw of power. The entire coastal wave power in our country is very rich, with a total volume of about 500 million kw, and it can be used from about 70 million to 170 million kw, with a wide range of development and application scenarios.
“So, I think the future should take the path of developing blue power. This kind of power exists at night and has not been developed yet. Once it is developed, we have the ability to open up new ways for the country’s major dynamic development.” Wang Zhonglin said.
It is reported that the national “12th Five-Year Plan for Strategic Development”, “Renewable Dynamics Medium- and Long-term Development Plan for the Construction and Manufacturing Industry” and so on have clearly used the development of land energy as a national research and development task.
In the eyes of experts, the development of the land power, known as “blue power”, is to apply renewable power, solve the current dynamic crisis, reduce purification and carbon dioxide emissions, and improve the narrow and old face of the national rescue station, and the bottom is deserted. The service station’s future career level has serious strategic meaning and grand economic value.
Wave power generation suffers from bottlenecks
Today, since more than 90% of the land energy is wave energy, the development and application of wave energy has become a key technology for the development of countries around the world. In terms of wave energy generation, the UK, Sweden, Portugal, american, japan (Japan) and other countries are in the leading position.
While wave power generation in my country started late, it has developed rapidly. Today, micro wave power generation technology has matured, and small shore wave power generation technology has entered the world’s leading position, but the gap between large capacity and network wave power generation technology and foreign countries is relatively large, and the scale of wave energy development is much smaller than that of European countries such as Norway and the United Kingdom.
In comparison, the “Green Type No. 1” floating wave energy generator developed by the Guangzhou Institute of Dynamics of the Chinese Academy of Sciences, including a hydraulic power generator system with a capacity of 10kW and a 10kw direct drive generator system. It was officially launched at the Pearl River Estuary and successfully developed electricity. This marks that my country’s energy generator technology has achieved new breakthroughs.
But,The wave power development research and development research has been under development for nearly half a century. Its commercialization process lags behind wind and tidal energy. Due to the lack of useful energy harvesting technology, the land energy has developed farther and farther.Manila escort is behind green leaves such as wind and solar energy. “?” force collection.
The important reason is that all kinds of wave power generation technologies have such or that, and the resulting cost, effectiveness and reliability problems have not been completely solved. These key technical problems are the focus of attention in the academic and industrial circles today.
Today, the important thing about wave power generation is electromagnetic power generation. At present, the acquisition of earth energy is mainly based on the principle of electromagnetic induction. It uses the mechanical energy generated by sea surface movement to move the relative movement between the magnet and the coil, and forms an electromagnetic inductor to generate electricity. During the process of transferring from wave mechanical energy to electric energy, the generator is driven after primary or secondary mechanical transformation. This makes the structure of this type of generator complicated, the body is rough and not single to improve the power generation efficiency, and it is difficult to prepare and install, and it also brings great difficulties to floating fixation.
“The magnets and coils that form traditional electromagnetic inductors, which sink when placed in water, cannot float naturally in the water, unless a support tower is set up from the seabed tree. This greatly increases the difficulty and cost of the project. In addition, the irregular movement of the Shanghai waves makes traditional electricity Magnetic generators are difficult to collect wave energy. “Wang Zhonglin said, “But the large number of local mechanical energy in the local area are the wave energy contained in the seawater.” Chen Jun, a doctoral student at the Georgia Institute of Technology, also pointed out that these magnets and coils can only rest well and have no makeup. href=”https://philippines-sugar.net/”>Sugar baby is just a “filling” gift. It collects the energy of the water flow. Its purpose is relatively single and difficult to be corroded by seawater, which greatly restricts the ability of long-term applications.
A different type of pressure generator can directly convert mechanical energy into electrical energy, and the conversion effect is high, but the pressure generator is suitable for high frequency vibration, and the low frequency of the wave must be converted into high frequency vibration, which creates a huge difficulty for the implementation of the generator.
Scientists in the field of scienceSugar daddyIt seems that these disadvantages have reduced the energy efficiency of the local area and the cost of the system is relatively high, which makes it difficult to apply in large areas. Therefore, the innovation of the electric development form and the advancement of the power generation efficiency and the transformation of installation methods are the key technology and bottle heads for wave generation, and are the biggest challenge for the realization of “blue power” in the world.
overlapping wave electric generators
In recent years, friction nano electric generators have appeared and dozed off. After waking up, she found that she turned out to be a supporting role in the book, and she provided complete and innovative key technologies for high-function wave power generation.
In 2012, Wang Zhonglin, a top talent in the national “Thousand People Plan” and an academician of the Chinese Academy of Sciences, proposed the concept of “friction nano generator”.
This is a new form of electricity generation based on friction-induced electrolysis, with energy conversion efficiency up to 50%~80%.
The friction nano generator is realized by applying polymer data to coupling the frictional and static inductor. When two kinds of data are connected, the electronics move, which is friction and electricity. Pulling the two data at a small distance will cause a potential difference (voltage drop) on the two true electrode layers of the data, which is a quiet Sugar daddy inductor. To prevent this voltage drop, the Escort manila unit flows from TC:
