What is a wave power plant? Definition:
Wave power designate hydropower plants that convert the constant movement of ocean waves into electrical energy. All systems of this kind operated to date are prototypes in the experimental stage. Experts believe that wave power plants could in the future be able to cover between ten and fifteen percent of international electricity demand. However, as the technology is relatively young and many years of experience are lacking, it is impossible to predict how wave power plants will affect the ecological balance of the oceans.
Wave power plants are based on different modes of operation. So far, four different types of wave power plants have been developed:
In the so-called pneumatic chamber (1) are concrete pipes in which the incoming and outgoing water compresses air. This drives the turbines and thereby generates energy. The so-called sea serpent (2), on the other hand, works on the basis of joints connected by joints, located at the water surface, which are moved by waves and thereby a liquid through integrated generators and turbines. Other methods are the ramp (3), on which the waves are concentrated, thereby driving turbines, as well as those called bumps plate (4), which fluctuates by connection with the seabed under the action of the waves and thereby generates electricity.
The best locations for wave power plants include the Atlantic coasts of Scotland, Scandinavia and Spain as well as some coastal areas of the Pacific.
