In the lecture, the speaker mentions how sea creatures inspire people in making new devices that could harness wave power and generate green energy, At the beginning of the lecture, the speaker says that there is one device called the Oyster. The device sits on the sea floor, and it opens and closes as the waves pass over it. Also, the speaker mentions that there is one device that looks like a snake, which is called the Anaconda. It is made from a rubber tube and filled with water that floats below the surface. According to the speaker, when swell hits the front of the anaconda, the tube would squeeze and generate power. And the full- scale version will be 2000 meters long Lastly, the speaker indicates that there is another system that looks like a snake, but it is made of steel. It floats near the surface of the water. Same as the anaconda, they are both being tested now.
