Chinese Academy of Sciences developed a water-powered friction nano-generator

It is reported that the team led by Wang Zhonglin, a member of the National Top Ten Talents Program and a member of the Chinese Academy of Sciences, has developed a water-powered friction nano-generator that can generate megawatts of electricity per square kilometer of sea surface after use.

According to reports, if this water-powered friction nano-generator is placed in a network and placed in the ocean, it will transform the irregular movement of seawater into a continuous stream of electricity. According to experimental calculations, the sea surface per square kilometer will be able to produce megawatts of electrical energy output.

China's vast sea area, sea water flow around the clock, which provides a stable working environment for friction nano-generators. Relying on the ocean, this “blue energy” may surpass “green energy” and has broad market prospects, which can be used to collect kinetic energy from rivers, raindrops and waves. Through a combination of four basic modes, this generator can efficiently recover kinetic energy resources in the ocean, including up and down of water, waves, currents, and sea water. This generator is the first to achieve solid-liquid interface friction power generation. In the past, it was generally believed that triboelectric charging was only possible under dry conditions. This technology also enables simultaneous collection of water droplets and wave kinetic energy.

The use of ocean energy is the frontier of energy research in the world today. However, due to the high development cost, small scale and poor economic efficiency of ocean wave energy, it has always hampered its large-scale commercial development and utilization. Frictional nanogenerators convert mechanical energy into electrical energy through the coupling of triboelectric and electrostatic induction, which, unlike existing power generation technologies, makes it possible to collect wave energy.
