The ocean, which covers 71% of the Earth's surface of water, generates far more energy than people thought. However, the use of marine resources has always been a major problem facing mankind. The internal sphere is rotated by the kinetic energy of marine currents, mostly the intense and irregular sea waves caused by rip currents. Since the direction of marine currents is different from the wind direction, the generator is rotated and can thus generate electricity. We make the internal sphere symmetrical to ensure that it can rotate smoothly. Therefore, “Mola Mola” is able to use ocean movements, sea buoyancy, and the action-reaction force between gravity and buoyancy to generate electricity of at any angle. Moreover, moving slowly just like the ocean sunfish, “Mola Mola” operates in harmony with nature and does not disturb the calm sea at all.
