The rotation is good. Wind turbines are electrical equipment that convert wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat source. work, so rotating wind turbine type is better.
The buoy-type wave power generation device is a device that uses the airflow generated by the up and down movement of waves to generate electricity. This power generation device has an air tube. The water surface in the tube (equivalent to a piston) is relatively stationary, but the water surface can move up and down. Due to the ups and downs of the waves, the buoy moves up and down, fromso that the air in the air piston chamber inside the buoy is compressed and expanded by the "piston" on the water surface, causing the air to escape. The air piston chamber, thus driving the turbine generator, generates electricity.
Japan has also developed a cone-shaped floating body wave power generation device, which is also a buoy-type power generation device, but it uses the principle of resonance to produce electricity. The natural frequency of the floating body of this power generation device is equal to the frequency of the up and down movement of the waves, so it is this resonance that is used to generate electricity. The bottom end of the floating body is a cone, and the top of the cone has a propeller that can rotate forward and backward. When the floating body moves relative to the sea water, the propeller is drivenrotates and the generator is driven to produce electricity.
