The last oceanic energy generator is a device that harnesses the power of the waves. They move up and down with the waves, floating on the surface of the water, while pumping a piston so that the device will build up pressure and shoot a high pressure beam of water to spin a small turbine these are very efficient because the waves are constant and a factor that unlike wind will never change. The constant motion of the waves are continuous and provide a great amount of energy for these generators. ... The power from the heat of the earth's core. ...
