What is the principle of Hamming wave power generation device?

"Haiming" wave power generation device uses the power of waves to work. It is a huge floating body like an oil tanker. It is 80 meters long, 5 meters high, 0/2 meters wide and weighs about 500 tons. There are 20 holes in the bottom of the floating body. These holes are actually air chambers. When the waves keep moving up and down, the air in the air chamber is constantly compressed and expanded, just like a bellows, the air rushes back and forth to the blades of the air turbine and makes it rotate rapidly, thus driving the generator to generate electricity.

Here, the undulating motion of the sea waves plays the role of a general engine piston, making the slow undulating motion of the sea waves turn into a rapid rotating motion formed after the high-speed airflow hits the turbine. Because of the simple structure of the device, Hamming can convert 27% wave energy into electric energy.

"Haiming" wave power generation device was built in 1978, which can generate 2500 kilowatts, and the power generation cost is lower than other power generation methods. The first phase of the test was completed at 1980, and it is still being tested.
