The current development of ocean energy lags far behind the collection of wind or solar energy. At present, the collection of ocean energy, after decades of development, is mainly based on electromagnetic induction. However, there are some drawbacks to electromagnetic energy-based ocean energy acquisition.
First of all, the electromagnetic induction machine is mainly composed of heavy magnets and coils. Such a power generation device cannot naturally float on the surface of the water unless it is supported by a floating platform.
Second, these coil magnets are also very difficult to withstand the corrosion of seawater, making their long-term usability extremely challenging. Again, most of them are based on electromagnetic generators, which can only collect the energy of the water flow and have a relatively simple directionality.
Unfortunately, most of the mechanical energy of ocean energy is the wave energy that is contained on the surface of seawater. Therefore, these drawbacks make the energy efficiency of these ocean energy collecting devices not ideal.
Finally, costly electromagnetic induction generators also make it difficult for these generators to be placed on the surface of the ocean to collect ocean energy.
Recently, the main team consisting of Chen Jun, Yang Jin, Li Zhaolin, and Fan Xing, under the guidance of Wang Zhonglin, a professor at the Beijing Institute of Nano Energy and Systems, Chinese Academy of Sciences, proposed a method for a friction generator network.
Compared with the existing ocean energy gathering devices, the power generation technology consisting of a friction generator network has the following significant advantages: First, it is mainly based on the surface charge effect of polymer materials and a very small amount of metal electrode materials, and the technology is inexpensive. The product is lightweight and resistant to seawater corrosion, so it is extremely suitable for large-scale production, and can not only recover the mechanical energy of the water flow, but also float on the water surface to collect the fluctuation energy.
Second, the ingenious design of the structure enables the device to not only collect mechanical energy of large winds and waves, but also effectively collect small fluctuations. Again, the tunability of the mesh structure allows these devices to work not only in a wide range of waters, such as oceans and lakes, but also in small areas such as pools and streams.
Finally, a network structure consisting of thousands of friction generators has a very low failure rate. Even if one or two units fail, it will not have a major impact on the normal operation of the entire power generation network. Current experimental tests show that a square kilometer of ocean energy output can be expected to reach 1.15 megawatts. Large-scale power generation networks are expected to achieve DC or quasi-DC output. Related research results were published online in the ACS Nano magazine on February 26.
